Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur thermochemischen Energiespeicherung mittels Durchführung endothermer chemischer Reaktionen zur Speicherung von Wärmeenergie in Form von chemischer Energie in einer oder mehreren chemischen Verbindungen zur späteren erneuten Freisetzung in Form von Wärmeenergie unter Nutzung von chemischen Gleichgewichtsreaktionen unter Abkühlung bzw. Erhitzung zumindest eines Wärmeträgermediums, mit dem Kennzeichen, dass zur Speicherung und Wiederfreisetzung der Energie das chemische Gleichgewicht zwischen Borsäure und Bortrioxid gemäß der folgenden reversiblen Summenreaktionen genutzt wird: (I) wobei a) zur Energiespeicherung die endotherme Dehydratationsreaktion von Borsäure zu Bortrioxid durch Kontakt der Borsäure mit einem ersten Wärmeträgermedium durchgeführt wird, das Wärmeenergie auf die Borsäure überträgt; und b) zur Wiederfreisetzung der Energie die exotherme Rückreaktion, d.h. die Rehydratation von Bortrioxid mit Wasser zu Borsäure stattfindet, wobei die freigesetzte Energie von einem zweiten Wärmeträgermedium aufgenommen wird.
