What is green hydrogen?

We talk of green hydrogen when the method used to produce it is based on renewable energy sources.

Today, the majority of hydrogen produced is referred to as “grey”, because the production method relies on fossil fuels: coal, natural gas etc.

Green hydrogen production is different, being based on decarbonised energy sources: renewable electricity from wind or solar. To produce green hydrogen, a water electrolysis process is thus used, which produces no greenhouse gases.

Green hydrogen is therefore a clean energy carrier that allows diversification of the energy mix and helps the energy transition.
