Below you will find more information about our high-temperature thermal energy storage demonstration systems. With their help, we can further optimize our technology and adapt it to the needs of our customers.

Our megawatt-scale high-temperature heat storage “ORCTES” has been in operation since 2015 and confirms its reliability.

Our portfolio includes high-temperature heat storage for storing heat, as well as pressurizable high-temperature heat storage. The latter are used as thermal electricity storage.
