A thermal energy storage process for large scale electric applications
TL;DR: In this paper, a new type of thermal energy storage process for large scale electric applications was presented, based on a high temperature heat pump cycle which transformed electrical energy into thermal energy and stored it inside two large regenerators, followed by a thermal engine cycle which transforms the stored thermal energy back into electrical energy.
