Scalable Thermochemical Option for Renewable Energy Storage (STORES)
Project Innovation + Advantages:
The Michigan State University team will develop a modular thermal energy storage system that uses electricity from sources like wind and solar power to heat up a bed of magnesium manganese oxide (Mg-Mn-O) particles to high temperatures. Once heated, the Mg-Mn-O will release oxygen and store the heat energy in the form of chemical energy. Later, when additional power is needed, the system will pass air over the particle bed, initiating a chemical reaction that releases heat to drive a gas turbine generator. The low cost of magnesium and manganese oxides will enable the system to be cost competitive.
