6 FAQs about [Does hm stand for energy storage ]

Can hydrogen be a form of stored energy?

The element hydrogen can be a form of stored energy. Hydrogen can produce electricity via a hydrogen fuel cell. At penetrations below 20% of the grid demand, renewables do not severely change the economics; but beyond about 20% of the total demand, external storage becomes important.
