c. All three

Role of Green Hydrogen in Decarbonizing Industries

Green hydrogen, produced using renewable energy sources, is poised to significantly impact the decarbonization of heavy industries. This innovative energy solution offers a sustainable alternative to traditional energy sources.

Application in Fertilizer Plants

In fertilizer plants, green hydrogen can be a game-changer by replacing natural gas as a feedstock for ammonia production. This shift not only reduces reliance on fossil fuels but also cuts down carbon emissions significantly.

Use in Oil Refineries

Oil refineries can utilize green hydrogen in various processes, including hydrocracking and hydrotreating. These processes traditionally require hydrogen input, and using green hydrogen ensures a more sustainable operation.

Green Hydrogen in Steel Manufacturing

In steel plants, green hydrogen serves as an effective reducing agent, replacing coal or natural gas. This substitution is crucial for reducing carbon emissions in one of the most carbon-intensive industries.
