Hydrogen in the Chemical Industry: Transformation and Challenges

More than 95% of hydrogen used in the chemical industry is currently produced through methods like steam methane reforming, a process with significant environmental impacts. The shift towards green hydrogen production is essential for sustainability.

Green hydrogen is increasingly being adopted in various industries, including the production of fertilizers, explosives, and other chemicals. It's not only a critical element in creating various chemicals but also a key enabler for the industry's shift towards sustainability.

Countries like Australia, Canada, Chile, China, and India are investing in green hydrogen projects. For example, Australia is developing a large renewable energy export facility and a hydrogen valley in New South Wales. Canada's Project Nujio'qonik aims to be the country's first commercial green hydrogen/ammonia producer. In Chile, significant investments are being made to finance green hydrogen projects as part of their clean energy goals. Meanwhile, China, a global leader in hydrogen production, is increasing its green hydrogen output, and Germany has invested heavily in electrolyzer capacity to boost green hydrogen production​​.

Fertilizer Industry

‍

Green hydrogen is set to transform the fertilizer industry significantly. It can be used to produce green ammonia, which is essential for nitrogen fertilizers. Countries with access to cheap renewable energy sources, like Saudi Arabia and Australia, could become significant producers of green hydrogen and green ammonia. This shift is driven by the need to decouple fertilizer production from fossil fuels and reduce carbon emissions. However, the transition to green ammonia will require technology upgrades and significant investment. The cost of green ammonia is currently higher than that produced from fossil fuels, but this is expected to change by 2030 with technological advancements and increased access to renewable power sources​​​​.

Explosives and Chemicals

‍

Green hydrogen also needs to be used in the production of explosives and various chemicals. The production process for many chemicals requires hydrogen, and traditionally, this has been sourced from fossil fuels. Transitioning to green hydrogen in these processes can significantly reduce the carbon footprint of these industries. However, the use of green hydrogen in these sectors is still developing, with more research and investment needed to fully realize its potential.

Challenges and Future Prospects

‍

The transition to green hydrogen faces several challenges, including the need for technology upgrades, policy support to make the transition economically viable, and reducing higher production costs compared to grey hydrogen (hydrogen produced from fossil fuels and releasing about 5 tons of greenhouse gasses into the atmosphere for each ton of hydrogen produced). However, the potential benefits, such as reduced carbon emissions and less dependence on fossil fuels, make green hydrogen a promising option for the future of these industries.

Hydrogen's multifunctionality in the chemical industry is undeniable. As the industry moves towards a more sustainable and circular economy, hydrogen, especially in its green form, stands out as both a challenge and an opportunity. This transition will not only aid in achieving net-zero targets but also open up new product’s sustainable revenue streams for chemical companies.
