Support for sCO2 based energy storage
5 October 2023EarthEn, a Phoenix-based start-up, has been awarded first-of-its-kind funding by the Office of Electricity, US Department of Energy (DOE), along with US National Lab support via the Innovation Crossroads initiative.
Above: EarthEn’s sCO2-based energy storage: the basic idea
The two years of funding and support will enable EarthEn to significantly advance the commercialisation of its proposed long- duration energy storage technology making use of supercritical carbon dioxide (sCO2) based technology. The research will be carried out at the Knoxville, TN, campus of Oak Ridge National Laboratory.
EarthEn’s technology is a hybrid thermo– mechanical form of energy storage using sCO2 that is said to promise high efficiency and good flexibility for long-duration as well as shorter- duration energy storage.
EarthEn’s CEO Manas Pathak entered the Innovation Crossroads programme as one of only seven entrepreneurs selected this year for participation.
