Green Hydrogen

What is green hydrogen?

Green hydrogen is produced from water using renewable energy sources such as solar and wind power.

Hydrogen is generated through electrolysis, where electricity splits water into hydrogen (H₂) and oxygen (O₂).

Hydrogen is an ideal fuel from a climate perspective. When hydrogen is used, the only by-product is water vapour – no carbon dioxide emissions.

This makes hydrogen a key enabler of the green transition in industrial sectors and transport modes that cannot be easily electrified.

Use of green hydrogen in industry

Industry uses hydrogen in applications such as fertilizer production and fuel refining.
Green hydrogen can also be used in industrial processes requiring energy or chemical feedstocks.
In the steel industry – one of the largest sources of CO₂ emissions – hydrogen can replace coal in the reduction of iron ore.
Green hydrogen derivatives include e-methanol, e-methane, e-SAF, and e-ammonia.
