Energilagring
Energilagring är idag ett effektivt sätt att temporärt lagra överskottsenergi från till exempel vindkraft, industrier och kraftvärmeproduktion. Energilagring kan buffra och flytta överskottsenergi från sommar till vinter. Detta möjliggör en större andel förnybar energi i våra energisystem, vars elproduktion från sol- och vindkraftverk är mer ojämn och årstidsberoende.
