Un enorme impianto di accumulo di calore, il più grande di tutta Europa, una sorta di gigantesco 'boiler', è in costruzione a Berlino e servirà a fornire ai residenti nella capitale tedesca acqua calda ottenuta utilizzando l'elettricità proveniente da centrali solari ed eoliche in tutta la Germania.
Affidato all'azienda energetica Vattenfall, sarà inaugurato entro l'autunno: il serbatoio di stoccaggio sarà alto 45 metri con un diametro di 43 metri e una capacità di 56 milioni di litri d'acqua. Sarà riempito d'acqua nei prossimi mesi e, grazie a tecnologie innovative, sarà in grado di trasformare l'energia solare ed eolica in calore, che a sua volta potrà essere immessa nella rete secondo necessità, facendo fronte alla volatilità dell'offerta di energie rinnovabili.
Un punto d'incontro per le energie rinnovabili
Il Quotidiano 08.06.2022, 21:00
L'impianto da 50 milioni di euro avrà una capacità termica di 200 megawatt, sufficiente per soddisfare gran parte del fabbisogno di acqua calda di Berlino durante l'estate e circa il 10% di quello necessario in inverno.
