This is what makes the volatile gas so interesting for storing large amounts of electricity. In the hydrogen fuel cell, the energy converter and energy carrier hydrogen are clearly separated from each other. This means that hydrogen can be supplied or discharged again and again. Put simply, there are no limits to the amount of energy that can be stored. Specifically, the hydrogen in the fuel cell can act as an energy store for electricity from wind and solar farms.
The hydrogen fuel cell takes over when the sun stops shining or the wind stops blowing and thus becomes a hydrogen power storage. Here too, the fuel cell is a convincing solution. It has to fulfill less, but no less important requirements in residential buildings. The combination of photovoltaics, electrolyser, hydrogen storage and fuel cell makes homeowners partially self-sufficient with renewable energy. This is because the electrolyser uses surplus solar energy to produce and store hydrogen. No wonder that more and more private users are buying a hydrogen fuel cell.
