Green hydrogen is the hydrogen produced through electrolysis of water using electricity from renewable sources.

Green hydrogen is expected to play a significant role in decarbonizing all three of the mentioned heavy industries.

Green hydrogen can be used in the production of ammonia, which is a key component for many fertilizers. Fertilizer production is energy-intensive and often relies on fossil fuels, particularly natural gas. By using green hydrogen as a clean energy source, the carbon emissions from this industry can be significantly reduced

Green hydrogen can be used in oil refineries to process crude oil into various products, including gasoline, diesel, and jet fuel. This can help to reduce the carbon emissions from the refining process.

The steel industry is one of the largest industrial emitters of carbon dioxide. Green hydrogen can be used in place of coal in the steelmaking process, significantly reducing the industry's carbon emissions.
