How is hydrogen made.
Hydrogen can be produced when there is a surplus of variable renewable electricity, then stored and used to generate heat or to re-generate electricity. Hydrogen created through electrolysis using renewable energy is commonly referred to as "green hydrogen." It can be further transformed into synthetic fuels such as ammonia and methanol.
