Boston is racing to decarbonize its public housing by 2030. The latest tool it’s deploying to reach that goal? Window-straddling heat pumps.
Last week, the Boston Housing Authority announced that it’s piloting the electric technology at Hassan Apartments, a 50-year-old public housing community with 100 units for older people and adults with disabilities. The modular appliances, made by California-based startup Gradient, plug into a typical 120-volt wall outlet and will replace the apartments’ outdated, much less efficient electric-resistance system.
“We believe that low-income people and the families and individuals who live in our buildings deserve access to 21st-century technologies and home comforts, just like anyone else out there,” said Joel Wool, the agency’s deputy administrator for sustainability and capital transformation. “We’re also doing our part to reduce air pollution and combat climate change.”
The Boston Housing Authority has ordered about 100 window heat pumps for the project. Two other Massachusetts housing agencies are also piloting Gradient’s appliances, the company announced last week: the Chelsea Housing Authority, which is testing about 400 heat pumps, and the Lynn Housing Authority & Neighborhood Development, which is trying out roughly 200 heat pumps, about half of which are already installed.
Outside of Massachusetts, in 2022, the New York City Housing Authority (NYCHA) committed to purchasing a total of 30,000 of the devices from Gradient and global appliance maker Midea over a period of seven years. The agency has been learning from an initial 72 heat pumps installed, and their performance has been positive enough that Gov. Kathy Hochul (D) announced on Friday $10 million to fund demonstration projects statewide.
Heat pumps, which are essentially reversible air conditioners, are key to electrifying heating. They provide potentially life-saving cooling, too. Because they shift around ambient heat instead of generating it anew, the appliances are routinely two to four times as efficient as electric-resistance and fossil-fuel-fired options. (Gradient claims its heat pumps are also about 50% more efficient than plain old window AC units.)
But retrofitting a building with a conventional heat-pump system can be a complex undertaking, requiring electrical upgrades and new refrigerant lines that run to individual air-handling units in each apartment, for example. Window heat pumps might require some trade-offs in terms of efficiency, but they also sidestep those serious installation hurdles.
That ultimately makes them faster and cheaper to deploy, as well as less disruptive to tenants, according to Wool. Two workers can install one of Gradient’s 140-pound heat pumps in about half an hour, NYCHA estimated, draping its saddle shape across a windowsill. And a July study by the American Council for an Energy-Efficient Economy found that window heat pumps are typically the lowest-cost option for efficiently decarbonizing space heating, coming in at an average lifetime cost of about $14,500 per apartment compared to between $22,000 and $30,000 for large-scale heat-pump systems.
For its pilot, the Boston Housing Authority is paying $5,450 per residence to retrofit with window heat pumps — about one-eighth of what it has spent to update other buildings with conventional heat-pump systems: approximately $40,000 per unit, according to Wool.
Electric and gas utility Eversource is fully funding the project through the state’s energy-efficiency collaborative, Mass Save. Once the retrofit’s complete, the Boston Housing Authority expects to save up to $60,000 in energy costs per year.
In New York, window heat pumps are already making deep cuts to energy use. At the NYCHA-owned Woodside Houses, going from a gas-powered steam system to the appliances slashed the amount of energy consumed for heating by 85% to 88%, according to preliminary results from NYCHA.
“This [reduction] sounds unrealistically large,” said Vince Romanin, founder and chief technology officer at Gradient. But “we roughly know the reasons.” Waste abounds with fossil-fuel systems: Boilers don’t perfectly convert fuel into heat, steam leaks on its way to apartments, and residents, lacking control over the temperature, are prone to throw open windows if they’re overheating, he noted. User-controlled window heat pumps avoid all of those issues.
Gradient has raised more than $31 million in venture funding and signed over $9 million worth of federal and California grants to develop its window heat pumps, which it has shipped to multifamily building owners and developers in 18 states, Romanin said. He declined to specify the cost per unit.
At the Hassan Apartments in Boston, installations are already underway and should wrap up by mid-November, said Wool of the city’s housing authority. The agency will monitor energy costs closely, as it weighs whether to deploy the tech at other properties. Across its 10,000-unit portfolio, heat pumps — of the conventional variety — serve just a few hundred apartments so far.
“We do think that window heat pumps are a great technology,” Wool said. “It’s also still an early one. We want to see how it performs.”
More than a decade ago, residents of Loudoun County, Virginia, banded together to buy up treasured open space before it became a strip mall and housing development, donating the land to the Piedmont Environmental Council instead. The nonprofit has maintained it as a unique blend of cattle pasture, a nature preserve, and a community farm that donates its yield to a local food pantry.
Now, a small corner of the farm has become what organizers say is a first for the state: a crop-based agrivoltaics demonstration project. They hope the combination of solar panels and vegetable farming will showcase how much-needed renewable energy can complement, not harm, agricultural lands, at a time when data centers are demanding more and more electricity.
The Virginia Clean Economy Act requires the state’s largest utility, Dominion Energy, to stop burning fossil fuels by 2045 and to develop 16,100 megawatts of land-based renewable energy by 2035 — mostly in the form of solar.
Virginia has more than enough room to meet that target without threatening great swaths of farmland. Using a conservative metric that 10 acres of land can host 1 megawatt of solar capacity, a Nature Conservancy analysis found that the state has 40 times more suitable land area than needed for solar fields, even after ruling out over 2 million acres of “prime conservation lands” including farmland.
Researchers from Virginia Commonwealth University determined that large-scale solar today is erected on less than 1% of the state’s cropland. Under a “high-growth scenario,” that figure could rise to 3.1% by 2035, including 1.2% of the state’s federally designated prime farmland. Yet low-density residential development may pose a far greater threat to those spaces, according to research by the nonprofit American Farmland Trust, which advocates for “smart solar” that doesn’t jeopardize agricultural land.
In fact, many landowners find that renting a portion of their land to solar companies can help their farming enterprise pencil out financially, reducing pressure to sell their property to developers. An acre of land, after all, may yield hundreds of dollars if devoted to crops but thousands if leased for panels.
And yet there’s no doubt that solar has grown exponentially in the state in the last decade, and that it has disproportionately displaced farmland. Cropland makes up 5% of Virginia’s total acreage but 28% of the land area now used for large-scale solar, the Virginia Commonwealth University researchers found.
Especially in the early years of renewable-energy construction, some companies set a poor example for responsible development, said Ashish Kapoor, senior energy and climate advisor with the Piedmont Environmental Council. “It was a little bit ‘Wild West,’” he said. “Those early projects in 2018, 2019 — there were a lot of significant runoff issues.”
As solar fields have gone up at a breakneck pace — replacing plots of forests as well as farmland — opposition to them has also grown. Virginia localities approved 100% of solar projects in 2016, according to reporting from Inside Climate News. By 2024, the approval rate had fallen to under 50%.
The increasing number of rejections stems from a “a mix of disinformation and resentment,” Kapoor said. But the tension between solar and farmland is real. “That’s a national thing,” he added. “It’s everywhere.”
Agrivoltaics — the awkward portmanteau of agriculture and solar photovoltaics — has emerged as a potential solution, wherein farmland is kept in production even while it hosts solar arrays. The most common application is sheep: They graze on vegetation beneath the panels and prevent the need for expensive and polluting mowers. Planting flowers in and around panels to supply honeybees and other pollinators is also popular.
Still, the Piedmont Environmental Council team wanted to experiment with a crop-based model because it fits better with what most farmers in the area are doing now: raising vegetables.
“You want to change as little as possible for the farmer,” said Teddy Pitsiokos, who manages the organization’s community farm.
Occupying a quarter-acre section of the nonprofit’s 8-acre community vegetable farm in Loudoun County, the agrivoltaics project is small by design. It features 42 ground-mounted solar panels with a total capacity of 17 kilowatts, two batteries for backup power during outages, and about 2,000 square feet of growing area.
The array will supply more than enough power to meet the farm’s needs, with additional headroom for a planned EV charger and a greenhouse that organizers want to electrify eventually. But the Piedmont Environmental Council isn’t trying to demonstrate scale. Rather, it hopes to carefully measure impact.
With the shade and protection from rainwater that they provide, how do the solar panels affect soil moisture and temperature? What’s the resulting crop yield? What do vegetables grown beneath and near solar panels look like, and how will consumers react? Do any contents from the panels make their way into the crops, posing health problems?
Most research has found that the answer to the last question is no. But the team still plans to test for contaminants in response to public concern as a show of good faith and transparency, and in an effort to address any potential barriers to agrivoltaics from the get-go.
While most crop-based agrivoltaics projects involve growing produce in the ground, the Piedmont Environmental Council’s farm also includes raised beds, which enable educational tours and widen the demonstration project’s relevance.
The beds do increase costs, said Pitsiokos. But the rationale for them, he said, “is so we can create data for people who might be doing this in an urban setting, a parking lot, or on some other nonpermeable surface,” he said. “We have productive agricultural soil; not everybody does.”
The experiment could also help inform compliance with new state rules designed to mitigate land loss from solar: Certain developers have to conserve land on a one-to-one basis for projects on prime farmland, but their burden is less if the array is used for agrivoltaics.
Pitsiokos also wants the data to reach educators, policymakers, and cohorts he hasn’t anticipated yet. “We want to share it with everybody,” he said, “because we know that we can’t predict who might benefit from it exactly.”
Perhaps most of all, the Piedmont Environmental Council hopes the project will reach farmers. Plenty are outspoken on solar, both for and against. But a 2024 survey from the American Farmland Trust found that most Virginia farmers and farmland owners hold nuanced views. Over half would consider solar if they could continue farming under and around the panels, according to the survey, but nearly two-thirds agree that solar developers should be responsible for returning land to a farmable state after an array is decommissioned.
With the project’s first crops of kale getting harvested this month, the Piedmont Environmental Council plans to make real-time data available as soon as this winter, for all to see. But grand conclusions won’t be forthcoming for another two or so years.
“Like with all scientific experiments,” Pitsiokos said, “slow is actually good.”
The Office of Clean Energy Demonstrations was supposed to be a launchpad for ambitious projects to help America lead the way on cleaner power and manufacturing. Now it’s been reduced to a shell of itself.
As the Trump administration slashes spending and fires workers across the federal government, the U.S. Department of Energy has emerged as one of the hardest-hit agencies — and perhaps no other of its divisions has been singled out as deliberately as OCED.
It’s a dramatic reversal for the four-year-old office. During the Biden administration, Congress endowed it with nearly $27 billion to try to scale up cutting-edge technologies that could curb planet-warming pollution from industrial facilities and power plants. Trump officials have in recent months hollowed out the office, canceling billions in previously issued awards for everything from low-carbon chemical manufacturing to rural energy resiliency, while also dismissing over three-quarters of its employees.
The situation is best summarized by the budget the White House has requested for OCED for the next fiscal year: $0.
Experts and insiders warn that the tumult within OCED and the DOE more broadly is eroding the private sector’s trust in the federal government and its ability to drive energy innovation.
“The administration has really created a chilling effect on the willingness of future early-stage technology developers to work with the Department of Energy,” said Advait Arun, a senior associate for energy finance at the Center for Public Enterprise, a nonprofit think tank.
Ultimately, that will stifle investment not only in the clean energy sectors the Trump administration dislikes but in those it has championed as well, such as advanced nuclear and geothermal. Former OCED staffers and contractors, who were granted anonymity to speak freely, told Canary Media that the disruption is a major setback for America’s efforts to launch the world’s next generation of energy technologies and industries.
“We are eliminating ourselves as a leader in the clean energy space, especially for the industrial complex,” one person said. “What I’m seeing is China is about to slip right into that position. Just logically and economically, I don’t understand the steps that are being taken.”
Congress created OCED in December 2021 to help deploy first-of-a-kind projects at commercial scale. The idea was for the government to absorb some of the risks and provide early capital to usher companies across the valley of death that lurks between promising research pilots and real-world operations that can move the needle on decarbonization.
The 2021 bipartisan infrastructure law provided OCED with about $21 billion over five years to scale up emerging technologies like small modular reactors and long-duration energy storage, and to advance ambitious “hubs” for producing hydrogen fuel and capturing carbon dioxide from the sky and smokestacks. In 2022, Congress gave OCED an additional $5.8 billion through the Inflation Reduction Act to help decarbonize U.S. manufacturing of materials like steel, cement, and chemicals.
“A lot of this stuff is a chicken-and-egg situation, where the private sector doesn’t want to come in [and invest] yet because it’s not proven,” said Zahava Urecki, a senior policy analyst with the Bipartisan Policy Center’s Energy Program.
“But we need the technology to go through this [demonstration] process in order to make sure it becomes proven, so that eventually we can have this in society,” she added. “And that’s where the federal government plays a key role.”
Over the course of three years, the office selected 116 projects in 42 states to receive over $25 billion in federal funding. For most awards, participating companies were required to cover at least 50% of total costs themselves — meaning the office expected its portfolio to spur nearly $65 billion in private investment, in addition to creating potentially hundreds of thousands of jobs.
Among the biggest winners were seven regional hydrogen hubs and two major direct-air-capture initiatives that would remove CO2 directly from the sky. The choices were not always broadly celebrated, and critics raised concerns that the hydrogen and carbon-capture initiatives in particular would do more harm than good for the climate by propping up unproven, energy-intensive projects involving fossil-fuel companies.
But other OCED picks garnered more public applause — and supported industries that President Donald Trump had flagged as priorities. In 2024, the office selected Cleveland-Cliffs for an award of up to $500 million to begin lower-carbon steel production in Middletown, Ohio, the hometown of Vice President JD Vance. Another manufacturer, Century Aluminum, got up to $500 million to help it build the nation’s first new aluminum smelter in decades, which would be powered by carbon-free electricity.
Former OCED staffers said they attempted to brief the incoming Trump administration on the office’s portfolio and to explain how they could support the president’s stated goals of boosting “American energy dominance” and “advancing innovation.”
However, from the time Trump took office on Jan. 20, “It became pretty clear that it didn’t really matter,” a former employee said.
It was quickly evident that Trump would, in fact, be adopting the right-wing policy platform Project 2025 after trying to distance himself from it on the campaign trail. The blueprint — which outlines ways to erase federal spending — called for eliminating “all DOE energy demonstration projects, including those in OCED,” in order to avoid “distorting the market and undermining energy reliability.”
For one staffer, “it all started crumbling” on Day 1, when the White House issued an executive order to halt federal work on “diversity, equity, and inclusion” — a measure that affected OCED’s grant recipients. Under former President Joe Biden, the office required participants to create community-benefit plans to ensure the billions in taxpayer dollars went to projects that included neighbors in the planning process and supported local economies. Under Trump, the strategy became a liability.
A blitz of federal funding freezes and layoffs — and court reversals and injunctions — then ensued, creating chaos across federal agencies and for all the outside companies that hold or held government contracts. In late January, the White House extended federal workers a “deferred resignation offer” that would allow people to resign from their jobs and go on leave with pay through Sept. 30, the end of the fiscal year.
Few OCED staffers initially took the offer. But after several months of chaos, about 77% of workers at OCED signed the deal when the White House extended it again in April. Insiders say that figure is likely even higher now. Across the DOE, some 3,200 employees within the agency’s roughly 17,000-person workforce opted to leave.
“That’s when folks at OCED actually started to realize it was going to be personnel changes that would first impact the projects, and not the program cuts,” according to a former employee.
On May 15, about a month after the staff exodus, Energy Secretary Chris Wright said the DOE would begin scrutinizing federal grants to “identify waste of taxpayer dollars.”
The agency started requesting additional information for 179 awards totaling over $15 billion, with a focus on large-scale commercial projects. Wright claimed that these awards were “rushed out the door, particularly in the final days of the Biden administration,” and required further review to ensure that individual projects were “financially sound and economically viable.”
Less than 3% of the over $25 billion in OCED’s awards portfolio had actually been paid to projects as of March 31, in part because larger grants were meant to be doled out in tranches over a long development timeline, according to EFI Foundation, a nonpartisan organization led by Ernest Moniz, who served as energy secretary during the Obama administration.
Project developers interviewed by EFI claimed that, contrary to Wright’s statement, OCED’s “due diligence was more rigorous than what private-sector investors would conduct” and that, rather than undergo the office’s laborious process, “faster decisions would have better aligned with developer timelines,” the foundation said in a June report.
Wright didn’t wait long to begin nixing projects. In late May, he announced the termination of 24 awards issued by OCED totaling over $3.7 billion, including funding for carbon capture and sequestration and projects within the office’s Industrial Demonstrations Program that aimed to reduce emissions from iron, cement, glass, and chemicals production.
“These clean energy projects were enshrined into law by bipartisan majorities and represent the will of Congress,” Sen. Martin Heinrich, Democrat from New Mexico, said in a recent statement to Canary Media. Heinrich and other congressional Democrats sent a letter to Wright on Sept. 9 accusing the DOE of undertaking a “haphazard, disorganized, and politically driven” cancellation process.
More funding cuts arrived earlier this month, when the DOE said it was slashing 321 grants for projects almost entirely in states that voted for Democratic nominee Kamala Harris in the 2024 presidential election. A spreadsheet of the cuts lists 11 newly affected OCED projects totaling nearly $2.5 billion, including for two major hydrogen projects planned in the Pacific Northwest and California. The October list also repeats five OCED-backed initiatives that first appeared in the May announcement.
Project developers have said they’re appealing the award terminations and are in continued talks with the DOE. Still, it’s unclear how much capacity the office has anymore to helm those discussions.
Wright said in an Oct. 3 interview that more cancellations would follow, and early last week rumors swirled about a second spreadsheet that appeared to outline deeper cuts for carbon-removal projects, hydrogen hubs, and other OCED projects. The nature of the list remains unclear, but if it proves to be a signal of cuts to come, it would cancel another $6.1 billion in awards from OCED.
The project areas that have yet to be cut — or to appear on any potential hit lists — include advanced nuclear energy and critical minerals. Additionally, the energy agency said it has started tapping OCED’s authority to make some new grants for Trump’s favorite energy source: coal-fired power plants. Should the office shutter, these awards would likely be managed by other divisions within the DOE.
Alex Kizer, a senior policy advisor at EFI, noted that gutting OCED won’t end America’s efforts to decarbonize heavy industries.
In the case of cement and steel, demand for low-carbon materials is growing within U.S. and global markets as tech giants look to build less carbon-intensive data centers, and as state governments and European and Chinese regulators work to rein in industrial pollution. Still, losing grants — and the DOE’s seal of approval — will undoubtedly make it harder and more expensive for companies to raise private capital for commercial-scale projects. Stifling the DOE’s role as a gatherer and publisher of real-world lessons could further slow progress, Kizer said.
“The potential for breakthrough across different energy sectors is so significant,” he said of OCED’s work, noting that “a relatively small investment from taxpayers could have an enormous benefit to taxpayers over time,” in terms of delivering cleaner, more reliable energy. “Who says no to that?”
Barbara Kelley remembers when her car and windows were routinely coated with a thin film of coal dust that had drifted over from the power plant on the edge of her neighborhood in Salem, Massachusetts. She remembers the noise as a conveyor belt lifted the coal into the building. She also remembers how pleased she was when the community started to discuss the possibility of building an offshore wind terminal on the site when the plant eventually closed.
“The coal plant — it worked, it gave us energy, but it was time to change,” Kelley said. “My reaction was, having a wind port is part of having wind energy — and that’s a good thing.”
In the years since the coal plant shut down in 2014, Kelley and many other community members have worked to promote the goal of transforming part of the property into a staging ground where wind turbine blades, tower sections, and nacelles can be prepared for transport to offshore construction sites south of Cape Cod and north in the Gulf of Maine. The vision was to turn Salem Harbor, one of the country’s oldest ports, into a linchpin of the then-burgeoning offshore wind industry and provide an economic boost to some of Salem’s most disadvantaged residents.
Last year, that dream seemed close at hand. City and state leadership had embraced the idea. The state had promised a hefty investment, and the Biden administration had awarded the project a sizable grant. Massachusetts Gov. Maura Healey attended a groundbreaking ceremony for the development in August 2024, and operations were expected to begin in 2026.
Project developer Crowley had agreed to pour nearly $9 million into a community benefits agreement that included job training, childcare, emergency services, and local sustainability and resilience efforts. Planners estimated construction and operations would create hundreds of jobs. And the whole process of bringing the idea to life gave community members a sense of agency and hope for their city.
Then this August the Trump administration announced that it would cut off $679 million in federal funding for offshore wind ports. The move was part of President Donald Trump’s ongoing attacks on offshore wind, the impacts of which are being felt far beyond the nascent sector. Now, like those in so many communities across the country, the people of Salem find themselves facing the fallout of national political priorities, and wondering whether more than a decade of work will ever bear fruit.
“I feel like we’re all a little bit in the dark still,” said Lucy Corchado, a local activist who was part of the group that negotiated the community benefits agreement. “I hope we hear some good news, but I’m not sure that’s going to happen.”
Community advocates first started floating the idea of building a wind port on Salem Harbor roughly 15 years ago. At the time, plans were underway to build a commercial wind farm off Cape Cod, and the coal plant’s closure looked likely. The advocates saw a promising future for the large industrial waterfront parcel in what seemed to be a growing energy sector.
Once the epicenter of the spice trade in early America, Salem has a deepwater port that today serves mostly recreational boaters, tourist outings, and the occasional cruise ship. Though the city is home to a hospital, university, and thriving hospitality sector, it also has a median household income well below the average in most surrounding towns and statewide.
When the owner of the coal plant proposed building a natural gas–burning facility on the site, activists from Salem Alliance for the Environment, or SAFE, were skeptical of replacing one fossil fuel with another. However, they decided not to oppose the plan for a new, smaller plant and to instead push for the rest of the property to be used for an offshore wind port that could both contribute to the decarbonization of the grid and create new opportunities for local residents.
“It wasn’t that we were really supportive of the gas plant, but we had bigger dreams of a wind port coming into town,” said SAFE founder Patricia Gozemba. “Our dream played out.”
In 2022, then-Gov. Charlie Baker, a Republican, announced the state would make a $75 million investment in the port, and the project was also awarded a $34 million grant from the federal Port Infrastructure Development Program. Two years later, the Massachusetts Clean Energy Center bought 42 acres of the former coal plant property, with the intention of leasing it to energy and marine developer Crowley. The City of Salem acquired five adjacent acres.
The plans enjoyed widespread support in the city.
“We’re a uniquely progressive community,” said SAFE executive director Bonnie Bain. There was no organized opposition to the wind port idea beyond occasional grumbling by Facebook commenters, she said.
As negotiations between Crowley and the city got underway, SAFE and other groups started to worry that, despite their longstanding advocacy for the project, important community input was missing from the process.
“This wasn’t just a wind port — it was an investment in the community,” Bain said. “We want to make sure that when we build projects that they enhance the community.”
Advocates raised their voices, submitting testimony for state and local proceedings, attending planning board meetings, and hosting educational webinars about offshore wind. In 2023, SAFE and several Salem neighborhood associations and civic groups formed a coalition to ask for a seat at the bargaining table as the city and developer hammered out the community benefits agreement.
The coalition was determined to make sure that the project didn’t harm nearby residents and created opportunities for some of the city’s disadvantaged populations. The group met once a week — Thursdays at 4 p.m. — for a year to discuss strategy, write letters to the media, and plan for local and state meetings. Salem Mayor Dominick Pangallo agreed to include two coalition members — Kelley, representing the Historic Derby Street neighborhood adjacent to the planned port, and Corchado, representing The Point, a largely immigrant, lower-income neighborhood nearby — in the community benefit negotiations.
“We kind of pushed our way to the discussion table to make sure they heard what we were looking for,” Corchado said.
The parties struck a deal that included a range of measures. The city’s public schools were set to receive $40,000 annually for technical and vocational education programs and another $50,000 per year to expand prekindergarten childcare to help parents attend job training. Crowley also committed to offer paid apprenticeships and internships, help graduating students find jobs in the industry, and fund scholarships for local workers to access relevant training opportunities.
When Trump was elected in 2024, some port supporters held out hope that the project would escape the president’s well-known hostility to offshore wind. Corchado, however, was concerned from the beginning.
“We were so far along and the funding has already been secured. It was like, maybe it’s not going to be that bad,” she said. “But, yeah … it’s what I was worried about.”
The news on Aug. 29 that the federal funding would be terminated was an enormous disappointment for proponents. It also left them with questions about whether the lost funds would scuttle the plan entirely, force the developer to change course, or merely delay implementation. Crowley will say only that it is reviewing the action and determining next steps. The city of Salem is also figuring out what to do now.
“We are still working to pursue all avenues to address the funding termination,” the mayor’s office said in a statement. “That includes working to get it restored or, failing that, looking at how we could revise the project plan to account for the loss of what was around 10% of the expected construction costs for the port.”
Community members are feeling somewhat adrift as the concrete plans they invested so much time in become increasingly uncertain.
“It wasn’t necessarily surprising,” Bain said. “But it’s still dizzying when it actually happens.”
An enormous solar project planned for the Nevada desert was canceled last week while awaiting final federal approvals, an ominous sign for renewables development on public lands under the Trump administration.
Esmeralda 7 was unique for its size: It would have installed 6.2 gigawatts of solar generation and 5.2 gigawatts of battery capacity across 62,300 acres of Nevada desert. No other solar project in the U.S. comes close to that scale. It was also a test case for a new, more efficient approach to federal permitting, one that promised to get clean energy infrastructure built more quickly.
The solar colossus incorporated seven distinct solar-and-battery projects from different developers on adjacent parcels of land overseen by the federal Bureau of Land Management. Instead of each going through an exhaustive process to attain federal permits, the projects banded together to undergo a joint analysis by the BLM. The bureau completed a draft environmental review of the megaproject under the Biden administration, but didn’t release a final version. Instead, as first reported by Heatmap, the BLM website switched the project status to “canceled” on Thursday.
It’s not yet clear if the decision to cancel was made by the BLM or Interior Secretary Doug Burgum, or if the Esmeralda 7 developers pulled out, perhaps based on conversations with the government. An automated email reply from Scott Distel, the BLM contact for the project, said he is not authorized to work during the government shutdown and thus was unable to respond.
The BLM circulated a statement to media on Friday saying that “applicants will now have the option to submit individual project proposals to the BLM to more effectively analyze potential impacts.” Such a move would entail repeating the already-conducted environmental analysis for each project individually, after which the administration could simply move to cancel the projects again.
“While we await further clarity from BLM on its apparent decision to abruptly cancel these solar projects in the late stages of the review process, we remain deeply concerned that this administration continues to flout the law to the detriment of consumers, the grid, and America’s economic competitiveness,” Ben Norris, vice president of regulatory affairs at the Solar Energy Industries Association, wrote in a statement Friday.
President Donald Trump swept into office declaring an “energy emergency” and pledging to unleash more American energy and bring down prices. Since then, though, his administration has intervened to obstruct several major power projects that would deliver renewable electricity to the grid at a time of swiftly rising power demand.
The White House attempted to halt two fully permitted offshore wind farms, the 810-megawatt Empire Wind 1 and the 704-megawatt Revolution Wind. Offshore wind requires permissions from the Interior Department’s Bureau of Ocean Energy Management, giving the administration leverage over this type of private enterprise. Those efforts to stop construction did not hold up, but they incurred millions of dollars of unanticipated costs for the developers, and damaged the country’s reputation as a safe place to invest in billion-dollar infrastructure projects.
Currently, only 4% of terrestrial, utility-scale renewable capacity sits on federal land, according to the National Renewable Energy Laboratory. But in the U.S. West, many federal parcels are well-suited for renewable energy; if these sites were successfully developed, they could greatly increase clean energy production.
Esmeralda 7 appears to be the first large renewable development on public lands to be officially canceled during the Trump administration, said Ted Kelly, director and lead counsel for U.S. clean energy at the Environmental Defense Fund.
Previously, he added, some projects that were expected to move forward were “sitting in limbo,” neither canceled nor approved on schedule. Now, Kelly said, there’s “a real concern” that public lands may be effectively off limits for wind or solar development for the duration of the Trump administration.
While it lasted, Esmeralda 7 modeled a new, more streamlined way to analyze a huge amount of renewable capacity.
“It increases efficiency on the government side, not having to recreate the same review of the same type of impact over and over again,” Kelly noted. Combining the permitting also helps in scrutinizing the cumulative effect of multiple projects, something environmental advocates have pushed for.
The BLM released its draft environmental impact statement in late July 2024, kicking off a 90-day comment period, which included an in-person public meeting and an online one.
The project would have impacted the desert landscape. But the draft environmental review identified those impacts and outlined mitigation efforts needed to protect endangered species and minimize disruption to desert plants. Esmeralda 7 also would have had environmental benefits by displacing polluting power production with emissions-free generation.
Projects that undergo thorough vetting and abide by the government’s conditions have a legal right to move forward, Kelly said. Under U.S. law, the government can’t cancel a project without mustering a set of reasons and evidence; the Administrative Procedures Act forbids “arbitrary and capricious” decisions that violate due process.
“It’s inconsistent with the law, but it’s also obviously inconsistent with what our country needs,” Kelly said of the cancellation.
Several prominent voices outside the clean energy industry expressed alarm at the news. Utah’s Republican Gov. Spencer Cox blasted the cancellation on X, writing, “This is how we lose the AI/energy arms race with China. … Solar with batteries can now be close to baseload power and we should keep these projects rolling until we get the gas/nuclear/geothermal plants we need.”
Billionaire John Arnold, who made a name for himself as a gas trader at Enron, also tweeted about the cancellation, saying, “I’m increasingly worried we’re headed for the cliff.” Coal, hydropower, and nuclear are not projected to grow much in this decade, he noted, so “all growth has to come from gas, solar & wind.”
Halting new wind and solar developments thus threatens the country’s ability to grow electricity supply even as AI companies and leaders in other industries are in desperate need of more power.

Renewable energy just notched a major milestone.
Worldwide, renewables produced more electricity than coal across the first half of this year — a first, according to clean-energy think tank Ember.
The global revolution in solar deployment made the milestone possible. The energy source more than doubled its share of global electricity generation over the last four years alone, rising from 3.8% in 2021 to 8.8% in the first half of 2025. Wind power also grew modestly during the first half of the year.
Taken together, the two clean-energy sources increased fast enough to not only meet all new electricity demand in the first six months of 2025, but to displace a bit of fossil fuel use as well.
Despite the progress, coal remains the single largest source of electricity in the world. No renewable-energy source on its own — be it wind, solar, hydro, or bioenergy — measures up to coal. And although renewable energy on the whole has now surpassed coal, it’s not like coal generation is plummeting. Power plants still plowed through more coal in the first half of this year than they did in the first half of 2021.
But coal power is stagnant. Meanwhile, renewables, and solar in particular, are ascendant. This latest milestone is worth celebrating not because fossil fuel use has been dealt a fatal blow, but because it’s a clear illustration of the trajectory each energy source is on.
For the world to truly reorient itself around energy sources that don’t bake the planet and spew toxic fumes into the air, those trends must not only continue but accelerate. Coal — and eventually gas — will need to decline as assuredly as renewables soar. Let’s call this a step in that direction.

The specter of additional, deeper federal funding cuts is haunting the clean-energy sector. A Department of Energy list shared this week with Canary Media suggests the agency is thinking about canceling a whopping $23 billion worth of energy projects.
Well, maybe.
Here’s what we know for sure: Last week, the DOE terminated $7.56 billion in federal funding for grid upgrades and energy projects, which were largely set to benefit Democratic-voting states. Right after, Energy Secretary Chris Wright called the announcement a “partial list” and promised that more cuts were coming — in both blue states and red ones.
From there, it gets fuzzier.
On Tuesday, sources shared a leaked spreadsheet with Canary Media that looks a lot like a follow-up to last week’s hit list. It lists the word “terminate” next to not only the 321 grant cancellations from last week, but hundreds of other projects too.
But despite headlines declaring this a new wave of grant cancellations, the exact nature of the list remains murky. A former DOE official who spoke on condition of anonymity told Canary Media’s Jeff St. John that the list is legitimate and that it represents the grants DOE officials have recommended for cancellation to the White House.
DOE, meanwhile, hasn’t confirmed the list’s authenticity and denies that it has yet decided to cancel any of the projects that appear only on the second list. In a statement, the DOE said it is still conducting an “individualized and thorough review of financial awards made by the previous administration,” and that “no determinations have been made other than what has been previously announced.”
Recipients who appeared only on the second list also say they haven’t heard that their grants will be canceled.
Vikrum Aiyer, global policy head at carbon-capture startup Heirloom, whose major direct-air capture project was included on the second list, told Canary Media’s Maria Gallucci that the company wasn’t “aware of a decision from DOE” to cancel its federal award.
Alliant Energy, a utility holding company whose Wisconsin Power and Light subsidiary was listed on the new spreadsheet, said in a statement that it has not been made aware of changes to its DOE grants.
And aside from the two blue-state hydrogen hubs whose funding was cut last week, several of the firms working on the other five hubs have yet to receive cancellation notices, Alexander C. Kaufman reports.
At best, the latest leaked list is just another layer of chaos and uncertainty for federal funding recipients, who are stuck trying to get answers about the status of their projects from a department that has been depleted by layoffs. At worst, though, it’s a harbinger of billions more in cuts to come for innovative American energy projects.

State and federal hurdles pile up for community solar
Community solar is in trouble, and it’s not just because of federal shakeups, Canary Media’s Alison F. Takemura reports. These shared arrays help make solar power accessible to those who can’t put panels on their own roofs, whether that’s because they rent, can’t afford them, or face other barriers. That power can in turn help households reduce their bills.
But the One Big Beautiful Bill Act signed in July set an early sunset for tax credits that can cover as much as half of a community solar array’s cost. And states are also contributing to the decline. Developers in New York, a major community solar market, are facing higher costs for land and permitting, while in Maine, developers have to reckon with changes to its solar net-metering program, as well as lowered compensation and new fees for community solar projects.
Those state challenges, combined with the looming threat of more federal funding cuts, have all led Wood Mackenzie to reduce its forecast of new community solar installations by 8% through 2030.
Global clean energy keeps growing
Two new reports contain some good news for clean energy around the globe. For starters, solar and wind installations outpaced global power demand growth in the first half of this year, according to an analysis out this week from think tank Ember. And in a first, renewables also generated more power than coal over the same period.
The International Energy Agency meanwhile predicts renewables’ global expansion will continue. Renewable power installations will more than double by 2030, it forecasts, with solar accounting for 80% of that new generation. That’s some fast growth, but it’s still well short of the tripling the agency has called for to mitigate the worst effects of climate change.

A correction was made on Oct. 10, 2025: Heirloom has a direct-air carbon capture project, not a hydrogen-hub project.
In July, China launched the world’s largest green hydrogen plant. One month later, India’s government backed 19 projects designed to make the country a leader in producing green hydrogen, which could help decarbonize everything from steel to shipping. Saudi Arabia and the United Arab Emirates are pumping billions of dollars into infrastructure to produce and export the fuel over the next few years.
The United States, meanwhile, is yanking funding for some of its most ambitious clean-hydrogen projects.
Last week, as part of a list of 321 grants revoked in the name of saving $7.5 billion in spending, the Department of Energy rescinded $2.2 billion in awards to two of the seven hydrogen regional hubs established under the bipartisan Infrastructure Investment and Jobs Act. Unlike the five other hubs, the law designed the terminated projects, in California and the Pacific Northwest, to focus exclusively on hydrogen made with renewable electricity, making them an easy target as the Trump administration slashes Biden-era clean energy projects.
Now this week a second Energy Department list shared with Canary Media indicates the agency is considering whether to pull funding from all seven hydrogen hubs, including those in Texas, Appalachia, and the mid-Atlantic and two in the Midwest.
It’s not certain whether the entire $24 billion worth of awards on the new list will be eliminated. Companies whose projects appeared only on the second list, including utilities and carbon removal firms, have yet to receive notice of cancellation. While federal officials gave companies involved in the West Coast hubs a warning before announcing the cuts last week, three separate producers involved in the other five hubs had not heard from the administration as of Thursday, according to California Hydrogen Business Council CEO Katrina Fritz, who checked in with the sources.
But already, the potential cuts are sowing doubt within the emerging sector — and in the clean energy space more broadly.
“Any amount of uncertainty in funding is really detrimental to private-sector investment, and that’s just not a good way to spur innovation domestically and compete on a global stage,” said Rachel Starr, the senior U.S. policy manager for the hydrogen program at the Clean Air Task Force. “Plenty of other countries are investing in this. We’re going to lose our competitive edge if we stop.”
“Yeah, I’m worried”
It remains unclear whether the document outlining a fuller list of cuts, which a lobbyist told E&E News was weeks old, represents an expansion of the previous cuts or a maximalist proposal from which the earlier terminations were whittled down.
In a statement, the Energy Department said it was “unable to verify” the list but that the agency “continues to conduct an individualized and thorough review of financial awards made by the previous administration.”
A former Energy Department official with direct knowledge confirmed that the list is legitimate and said that it represents the grants DOE officials have recommended for cancellation to the White House. The official suggested that the agency is obfuscating its plans to pull the grants to regional hubs in red states until after a federal budget is passed, an effort to prevent congressional Republicans from adding an amendment that preserves the funding into the budget.
“They can’t do that in the middle of a government shutdown,” the official, who spoke on condition of anonymity, told Canary Media. “I do expect them to cancel these funds … [but] not until there’s a full-year appropriations [bill].”
Already, key Republican lawmakers have expressed concern.
“Yeah, I’m worried,” Senate Environment and Public Works Committee Chair Shelley Moore Capito told E&E News when asked about the possibility of losing funding for West Virginia’s hydrogen hub. “It’s a big deal for us.”
The uncertainty only adds to the challenges facing the hydrogen industry.
The Biden administration created a two-pronged hydrogen strategy via the bipartisan infrastructure law and the Inflation Reduction Act. The IRA’s tax credit for clean hydrogen production, known as 45V, was meant to help spur supply of the fuel. The policy survived the rollbacks in the One Big Beautiful Bill Act that Trump signed in July, but Republicans shortened the timeline for the write-offs from 10 years to two.
The hydrogen hubs, meanwhile, were meant to coordinate producers and offtakers to create regional ecosystems that could someday be interconnected with pipelines and other infrastructure. Even before the cuts, however, the hubs were struggling to generate enough demand.
“Low demand explains why the West Coast hydrogen ambitions have never amounted to much,” Martin Tengler, the analyst who heads the hydrogen research team at the consultancy BloombergNEF, wrote in a memo to investors Monday. “Low demand stems from a lack of incentives such as the quotas or carbon prices that are present in Europe, combined with a focus on sectors where hydrogen use is highly uneconomical.”
As a result, he argued, the decision to slash funding for those two hubs “has little direct impact on the pipeline of projects BloombergNEF has expected to come online by 2030.”
Of the six commercial green hydrogen projects larger than 1 megawatt that the consultancy tracked in its latest outlook report, four have reached a final investment decision and just one is operational. “All five are very small,” the investor note stated.
In an email to Canary Media, Tengler said the impact of eliminating funding for all the hubs “would be negative, but the most important things are the tax credits.”
Back to the States
The hubs won’t necessarily fall apart without the federal grants.
California’s regional hub, known as the Alliance for Renewable Clean Hydrogen Energy Systems, or ARCHES, plans to continue without the financing and could turn to state funds to make up the difference. The Golden State’s newly overhauled cap-and-invest program is one potential source. The state Clean Truck and Bus Vouchers program, known as HVIP, and the California Energy Commission’s Clean Transportation Program Investment Plans could bolster offtakers.
“California has been a hydrogen hub for many years, and it’s getting bigger and bigger,” Fritz said. “It’s already in application. There are people riding on hydrogen fuel-cell buses every day in California.”
Roxana Bekemohammadi, executive director of the U.S. Hydrogen Alliance, said it’s possible that Congress could extend the 45V tax credit before it expires at the end of 2027. But in the meantime, she said, “state-level hydrogen incentives are the most stable path forward.”
Whether states can deliver a green hydrogen industry at scale, however, remains to be seen — and removing billions in federal funding certainly doesn’t make the task easier.
“The cuts to these hubs seem shortsighted and ultimately will result in the loss of jobs in our country,” said Carrie Schoeneberger, an industrial analyst who covers hydrogen for the Natural Resources Defense Council. “This will put the U.S. a step back and threaten U.S. leadership, which is against the stated aims of the current administration for American energy dominance.

The first wind farm slated to plug into New York City’s grid has already endured one political catastrophe this year. Now, a logistical crisis looms on the horizon.
Equinor’s Empire Wind is a 810-megawatt project being built about 20 miles off the shore of Long Island, promising enough energy to power 500,000 homes once completed in 2027. The Trump administration halted construction in April, but allowed it to resume in May. The latest challenge came on Thursday with the unexpected cancellation of a contract for the massive new wind-turbine installation vessel that Equinor had been planning to use on the project next year.
Two shipbuilding companies broke out into a public skirmish — one unexpectedly cancelling a contract and the other threatening legal action — over the construction of the specialized ship. The fate of the vessel, which is already more than 98% complete and floating in Singapore’s waters, is now uncertain.
The cancelled $475 million agreement leaves Equinor scrambling to figure out how to maintain progress and bring Empire Wind online on schedule.
“We have been informed by Maersk of an issue concerning its contract with Seatrium related to the wind turbine installation vessel originally contracted by Empire Offshore Wind LLC for use in 2026,” said an Equinor spokesperson via email. “We are currently assessing the implications of this issue and evaluating available options.”
Only a handful of vessels in the world are capable of lifting, carrying, and piecing together the massive steel components of offshore turbines.
Thursday’s news highlights the complexity of bringing just one U.S. offshore wind farm over the finish line, given the combination of logistical difficulties and political obstacles put up by the Trump administration.
In an email to Canary Media, a Maersk Offshore Wind spokesperson confirmed that the company terminated its building contract with Seatrium “due to delays and related construction issues.” The spokesperson declined to comment further.
Seatrium told Reuters it was evaluating its options for the vessel, including via ongoing talks with Empire Wind, and considering legal action.
Singapore-based Seatrium is fresh off the monumental achievement of berthing a first-of-its-kind offshore-wind installation vessel in U.S. waters. In September, the company delivered the $715 million Charybdis from its Brownsville, Texas, shipyard to the Portsmouth Marine Terminal in Virginia. The American-made vessel is owned by utility Dominion Energy, which immediately put it to work building the largest offshore wind farm in the U.S. The ship’s smooth delivery is a major reason why the Coastal Virginia Offshore Wind farm is progressing fast enough to have a new March 2026 launch date.
The ship’s hull is 472 feet long and 184 feet wide, making it one of the biggest vessels of its kind in the world. And, more importantly, it was built to serve the entire U.S. sector — not just Dominion Energy’s project. In other words, the Charybdis could be a solution to Equinor’s new problem.
“Upon the completion of its charter with [Coastal Virginia Offshore Wind], the versatile Charybdis will be available to support a variety of projects, including offshore wind and other critical heavy lift shoreline projects, such as salvage operations or other energy projects,” said Jeremy Slayton, a Dominion Energy representative, in an email to Canary Media.
An Equinor spokesperson provided no comment about Charybdis but reiterated that the company is exploring all options. Having survived the recent political storm, the company is well positioned to navigate these latest headwinds.
About 30 miles off the coast of Virginia Beach, Virginia, workers have been building America’s largest offshore wind farm at a breakneck pace. The project will start feeding power to the grid by March — the most definitive start date provided by its developer yet.
“First power will occur in Q1 of next year,” Dominion Energy spokesperson Jeremy Slayton told Canary Media. “And we are still on schedule to complete by late 2026.”
In an August earnings call, Dominion Energy CEO Robert Blue provided a vague window of “early 2026” when asked when the 2.6-gigawatt Coastal Virginia Offshore Wind (CVOW) project would start generating renewable power for the energy-hungry state.
As of the end of September, Dominion had installed all 176 turbine foundations — “a big, important milestone,” per Slayton. That accomplishment involved pile-driving 98 foundations into the soft seabed during the five-month stretch when such work is permitted. Good weather helped the work move along quickly, as did the Atlantic Ocean’s unusually quiet hurricane season.
Speed is key when building wind projects under the eye of a president who has called turbines “ugly” and “terrible for tourism” — and who has followed up with attempts to dismantle the industry.
Had CVOW not finished foundation installation by the end of this month, turbine construction would have been delayed until next spring. Federal permitting restricts pile-driving to a May-through-October window to protect migrating North Atlantic right whales. Such a delay would have made CVOW more vulnerable to the wrath of the Trump administration, which has already issued stop-work orders to two offshore wind farms under construction.
But Slayton said the threat of President Donald Trump’s interference doesn’t concern him. CVOW is, after all, one of only two in-progress offshore wind projects that hasn’t been directly attacked by the president.
“Our project has enjoyed bipartisan support from the beginning,” he said, pointing to backing from some of the state’s leading Republicans, including Gov. Glenn Youngkin and U.S. Rep. Jen Kiggans.
Kiggans, who represents the politically moderate Virginia Beach area, brought her concerns about Trump’s escalating war on wind to the House floor last month, when Congress returned from recess. She called CVOW “important to Virginia,” and House Speaker Mike Johnson (R-Louisiana) later told reporters that he relayed Kiggans’ message directly to Trump.
“I understand the priority for Virginians and we want to do right by them, so we’ll see,” Johnson told Politico’s E&E News, in a comment that broke from an anti–offshore wind narrative that’s taken root among many of his fellow House Republicans.
The project is crucial for helping the state meet a deluge of new electricity demand, as Virginia is at the center of the nationwide boom in data-center construction. CVOW will provide a huge amount of carbon-free power to the state and Dominion, its largest utility — helping both keep pace with rising demand without having to burn more polluting fossil fuels.
Kiggans also tied the success of CVOW to the needs of Virginia’s military installations.
“I always speak about that project in light of the national security benefit and that benefit to Naval Air Station Oceana,” Kiggans said last month in an interview with WAVY, a Virginia news station, noting that a partnership with Dominion is “giving Naval Air Station Oceana a $500 million power grid upgrade.”
Dominion has already spent $6 billion on the monumental effort to build CVOW, which has been 12 years in the making. Almost $1 billion of that investment has flowed to the local economy, creating 802 full- and part-time jobs in the state’s Hampton Roads region, according to G.T. Hollett, Dominion Energy’s director of offshore wind.
CVOW’s benefits are being felt nationwide too.
“The project has already created 2,000 direct and indirect American jobs and generated $2 billion in economic activity, strengthening the nation’s manufacturing supply chains and our regional economy,” said Katharine Kollins, president of Southeastern Wind Coalition.
Now Dominion will turn to the final phase of construction: turbine installation. The work is made possible by Charybdis — the first U.S.-built, Jones Act–compliant wind-turbine installation vessel — which arrived in Virginia’s Portsmouth Marine Terminal last month.
“When Charybdis is loaded up, it will have all the components to install four turbines with each trip,” said Slayton, who noted that the pace of the build is well timed given Virginia’s data-center boom. The state is facing “record growth and energy demand … maybe you’ve heard.”
