Under the leadership of University of Twente, the HERCULES project researches thermal energy storages with a metal-oxide base storage material. Together with the partners, Kraftblock will build a thermal storage demonstrator powered by new heating elements and renewable electricity. The storage material will be a hybrid of a thermochemical material based on metal oxide and a sensible storage material. The project aims to calculate and explore the storage properties of the metal oxide-based material and design a storage system for use under pressure.
Kraftblock’s part is designing the storage, providing insulation for use above 1,000°C, and constructing the storage vessel. The technology will first be tested on a laboratory scale.
