HYDROGEN IN THE CHEMICALS INDUSTRY
The most plentiful element in the universe, hydrogen, is becoming more and more popular as a vital resource for decarbonizing many different industries, including the production of chemicals. Hydrogen is becoming a popular choice to assist the chemicals industry in lowering its carbon footprint because of its ability to produce clean power and heat.

Today, fossil fuels are mostly used to produce hydrogen, which releases carbon dioxide during the process. On the other hand, more environmentally friendly techniques, such as electrolysis using renewable energy, can separate water into hydrogen and oxygen without producing any emissions. This “green hydrogen” stuff has the potential to change everything.
Hydrogen serves as a feedstock, fuel source, and reducing agent in the synthesis of chemicals. It is used as a feedstock in combination with other elements to create petrochemicals, methanol, and ammonia, among other necessary chemicals. By switching to green hydrogen production, related emissions would be eliminated.
Hydrogen can be used as a fuel to power production facilities and provide high-temperature heat for industrial processes. Green hydrogen would also take the place of burning fossil fuels here. By using this application, chemical companies may be able to turn surplus renewable electricity into hydrogen fuel and profit from it.
Hydrogen is also used in the production of chemicals to purify chemical streams and convert metal oxides into pure metals. These processes would be decarbonized by using green hydrogen.
Large chemical companies are currently initiating projects related to hydrogen. A $5 billion hydrogen production facility that will be fueled by 4 gigawatts of solar and wind energy is being built by Air Products and NEOM. Green hydrogen is provided by Linde to the German chemical facilities of Evonik. Yara plans to switch from producing ammonia to green hydrogen in order to completely eliminate process emissions.
The potential of hydrogen will only be realized with significant infrastructure and production investments. By providing incentives and funding research, governments can quicken development. Hydrogen must be integrated into all aspects of the chemicals industry’s operations.
The way forward is obvious: using hydrogen offers a workable way to significantly cut emissions from the production of chemicals. It is time to take action. A clean hydrogen economy is possible with dedication and foresight.
Here are some of the key applications of hydrogen in the chemicals industry:
- Ammonia production: Ammonia is created when hydrogen reacts with nitrogen. An essential component of fertilizers is ammonia. Emissions from the production of ammonia would be greatly decreased by using green hydrogen.
- Methanol production: Hydrogen is combined with either carbon dioxide or carbon monoxide to create methanol. It serves as a crucial feedstock for additional chemicals. By switching to green hydrogen, related CO2 emissions would be eliminated.
- Refining: Cleaner fuels are produced through the use of hydrogen in oil refining procedures like hydrocracking and desulfurization. The use of green hydrogen would lessen the carbon footprint of the refining sector.
- Metal production: Metal oxides are reduced to pure metal forms using hydrogen. The use of green hydrogen could decarbonize this application.
- Polymer production: Hydrogen feedstocks are used in the production of some polymers and plastics. Green hydrogen use would reduce these processes’ emissions.
- Fuel: High-temperature process heat from hydrogen can take the place of burning fossil fuels. Additionally, this application might offer chemical plants a means of making money off of extra renewable electricity.
- Purification: Chemical streams can be purified of contaminants like sulfur by using hydrogen. These purification stages could be made carbon-free by green hydrogen.
- Food processing: In food processing, hydrogen is used to hydrogenate oils and fats. Green hydrogen use would cut emissions.
In conclusion, increasing the production of green hydrogen has the potential to revolutionize the chemical manufacturing industry through the many applications of hydrogen. The carbon footprint of the industry would be greatly reduced as a result.
