The use of green hydrogen in oil refining is an emerging trend aimed at reducing carbon emissions. Green hydrogen is produced by splitting water into hydrogen and oxygen using electricity generated from renewable or nuclear sources. This method of production ensures that green hydrogen is free of greenhouse gas emissions, which is crucial for its role in decarbonizing industries like oil refining.
Hydrogen plays a pivotal role in oil refining, primarily in the processes of hydrotreating and hydrocracking. These two processes are critical in refining because they are responsible for consuming over 90% of the hydrogen used in the sector. Hydrotreating is essential for reducing sulfur content in finished petroleum products. Sulfur compounds, if not removed, can lead to harmful emissions when the fuel is burned and can also corrode engines and other machinery. By removing sulfur, hydrotreating ensures that the fuels meet environmental standards and are safer for use in vehicles and machinery.
Hydrocracking, on the other hand, is a process that breaks down heavier fractions of petroleum into lighter, more valuable products like gasoline and jet fuel. This process is particularly important for maximizing the yield of high-value products from crude oil. Hydrocracking involves breaking down larger hydrocarbon molecules into smaller ones, a reaction that requires hydrogen. The process increases the amount of usable fuel derived from crude oil, making it a key step in maximizing the efficiency and profitability of oil refining.
Currently, the majority of the hydrogen used in these processes is sourced as a by-product from other refinery operations, such as catalytic reforming and ethylene cracking. Catalytic reforming involves the conversion of heavy naphthas into high-octane gasoline components, while ethylene cracking is primarily concerned with the production of ethylene, a building block for various petrochemicals. Both of these processes generate hydrogen as a by-product, which is then used in hydrotreating and hydrocracking.
However, there is a growing trend towards replacing this hydrogen with low-carbon alternatives, particularly green hydrogen. This shift is driven by the increasing stringency of environmental regulations and the global commitment to reducing carbon emissions. Green hydrogen, produced through the electrolysis of water using renewable energy sources, offers a much lower carbon footprint compared to conventional hydrogen production methods. The integration of green hydrogen into oil refining can significantly reduce the carbon emissions associated with these processes.
Despite its environmental benefits, green hydrogen production is more expensive than traditional methods due to higher electricity costs and the limited availability of zero-carbon power. This means that for green hydrogen to be more widely adopted in oil refining, there needs to be a decrease in power costs and an increase in the efficiency and availability of zero-carbon power sources.
There are ongoing efforts and projects aimed at integrating green hydrogen into refinery processes. For instance, the REFHYNE project in Germany is working on installing and operating a large electrolyser at a refinery to provide bulk quantities of green hydrogen. This project is a part of a broader move towards decarbonizing the refining process and reducing emissions, a trend that is expected to continue and expand in the 2020s.
The potential market for low-carbon hydrogen in oil refining is significant. By 2050, the demand for low-carbon hydrogen in the global refining sector could reach 50 million tonnes per annum. This transition to green hydrogen could play a crucial role in reducing up to 35% of refining carbon emissions.
In an era where environmental concerns are paramount, the food and beverage industry is experiencing a paradigm shift. Historically reliant on fossil fuels, the industry is now embracing hydrogen as a pivotal element in reducing greenhouse gas emissions and promoting sustainability.
Green hydrogen is increasingly being explored for its potential in various industrial processes, including the hydrogenation of unsaturated fatty acids in animal and vegetable oils. This process is a key step in producing solid fats from liquid oils, which are then used in food products like margarine and other spreads.
Hydrogenation involves the conversion of unsaturated fatty acids to saturated fatty acids through a chemical reaction that adds hydrogen to these acids. This process alters the molecular structure of the fatty acids, converting carbon-carbon double bonds into single bonds. Unsaturated fats, which are generally liquid at room temperature due to their molecular structure, become saturated through hydrogenation and thus solidify. This is because the straighter chain of saturated fats allows them to pack more closely together, resulting in a solid form at room temperature.
Vegetable oils, for instance, are typically polyunsaturated and are transformed into semi-solid or solid fats through hydrogenation. This process is crucial in the food industry as it allows the conversion of inexpensive and abundant vegetable oils into more solid forms like margarine, cooking fats, and spreads. During the hydrogenation of vegetable oils, the number of double bonds that are hydrogenated is carefully controlled to produce fats with the desired consistency, such as soft and pliable margarine.
Furthermore, hydrogenation also affects the stability and melting characteristics of the resultant fats. The selectivity of the hydrogenation process, such as the preference for hydrogenating polyunsaturated fatty acids over monounsaturated ones, and the production of trans-isomers, are important factors that influence the final properties of the hydrogenated fat. This process is not only a method to alter the physical properties of the fats but also serves as a means to increase their shelf life and stability, as saturated fats are less prone to oxidation and rancidity compared to unsaturated fats.
In the context of green hydrogen, its usage in such industrial processes represents a move towards more environmentally sustainable practices. Green hydrogen, produced through the electrolysis of water using renewable energy sources, offers a cleaner alternative to traditional hydrogen production methods, which often rely on fossil fuels.

Methanol, a widely used simple alcohol, finds its applications across a range of industries, from manufacturing plastics to pharmaceuticals. Traditionally, methanol is produced through steam reforming of natural gas, a process that generates syngas, which is then converted into methanol. This method, though effective, is significantly carbon-intensive, contributing to CO2 emissions. However, a transformative shift towards sustainability in methanol production is underway, focusing on the integration of green hydrogen.
It's crucial to differentiate between grey, blue, and green methanol. Grey methanol is produced from natural gas or coal, blue methanol includes carbon capture in its production process, and green methanol is created using only renewable energy sources.
Grey methanol is the most commonly produced type. It is made via a synthesis reaction from methane, which is primarily obtained from natural gas or, in some cases like in China, from coal. This production process is not renewable and is linked to significant greenhouse gas emissions, particularly CO2. The reliance on fossil fuels makes it the least environmentally friendly type of methanol.
Blue methanol is also derived from natural gas, similar to grey methanol. However, the key distinction is that the production process of blue methanol includes carbon capture and storage (CCS).

”eMethanol” is produced from hydrogen generated from renewable electricity (green hydrogen) and captured carbon dioxide. The process of creating green hydrogen involves electrolysis, where electric current is used to separate hydrogen from oxygen in water. When this electricity is sourced from renewables like wind or solar farms, it results in a clean energy process.
The transition to blue and particularly green methanol is pivotal in decarbonization efforts and aligns with global sustainability goals, significantly reducing the chemical industry's carbon footprint.
The incorporation of green hydrogen, produced via water electrolysis powered by renewable energy sources, is revolutionizing methanol production. This innovative approach, known as green methanol (eMethanol) production, drastically cuts the carbon footprint associated with methanol manufacturing, aligning with global climate change mitigation efforts.
Innovative projects in countries like Denmark are exploring green methanol production from biogas. This process involves splitting biogas into CO and H2 using an electrically driven catalytic converter, supplemented with additional hydrogen from electrolysis, to create eMethanol. Such techniques are proving to be economically competitive, particularly under carbon taxation regimes. Additionally, global investments, notably in China and India, underscore the strategic importance of hydrogen in energy sectors, heralding a shift towards green hydrogen in various industries, including eMethanol production.
The production of eMethanol on an industrial scale offers a promising solution to storing renewable energy. It aids in reducing emissions during the transition to electric mobility and provides carbon-neutral mobility options. With countries increasingly aiming to limit or ban internal combustion engines, eMethanol offers a viable alternative. Pilot plants, particularly in Iceland, have demonstrated the feasibility of this approach. Companies like Siemens Energy are developing "Power to X" solutions, highlighting the maturity and readiness of the required technologies.
The International Renewable Energy Agency (IRENA) posits that renewable eMethanol could become cost-competitive by 2050 with targeted policies. Key strategies include systemic investment in technology and infrastructure and policy reforms to level the playing field for renewable methanol.
The integration of green hydrogen into production of eMethanol marks a critical step towards more sustainable industrial processes.
