Flexible storage systems help to adapt the weather-induced fluctuations in wind and solar energy production to consumption. Numerous consumers, interconnected by means of a smart grid, can take on the job of an energy storage unit by recharging their electric car at night, or stabilise the grid by for example switching on the washing machine during off-peak hours when there is plenty of electricity available.
One such storage system is the GP Joule Power Gap Filler, which uses excess wind power to produce hydrogen
through electrolysis. This hydrogen can be stored and later converted back into
electricity or used to power electric cars that use fuel cells. The Bosch battery
storage unit at Bürgerwindpark Braderup-Tinningstedt works just like a traditional battery.
