Energilagring med batterier och vätgas. Energilagring är ett sätt att lagra energi till dess den behöver användas. Det kan handla om att lagra när elen är billig och använda när den är dyr, eller att balansera kraftsystemet när väderberoende energislag inte kan producera el. Batterier och vätgas är två typer av energilager som är intressanta för det svenska kraftsystemet.
