Exploring The Great Potential Of (Ground)Water In The Energy Transition

Current
Deltares

Utrecht Area, Netherlands

Water heeft enorm potentieel om de energie transitie vorm te geven: de warmte en koude voorziening kan in potentie volledig verduurzaamd worden door warmte en kou uit oppervlaktewater af te tappen, op te slaan in grondwater, en te gebruiken wanneer het nodig is. De enige andere bron is elektriciteit voor de pompen en eventuele warmtepomp om de gewenste temperatuur te bereiken. De buffercapaciteit van warmte in water kan ook nog eens benut worden om de fluctuaties in elektriciteitsaanbod op te vangen: de warmtepompen gaan aan als het waait, en slaan de gewonnen warmte op in de bodem voor gebruik in koude perioden en situaties zonder zon en wind.
