Scalable Thermochemical Option for Renewable Energy Storage (STORES)
Technology Description:
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.
Potential Impact:
If successful, DAYS projects will provide new forms of long-duration stationary electricity storage systems that enhance grid resiliency, provide low-cost energy capacity, support grid infrastructure, and enable a greater share of intermittent renewable resources in the generation mix.
Security:
Long-duration storage can help prevent blackouts and smooth overall grid operation, improving resilience and enhancing grid security.
Environment:
New, extended storage options could enable greater integration of intermittent renewable energy sources, greatly reducing emissions from the power sector.
Economy:
Energy storage technologies could help improve grid efficiency and promote the growth of domestic renewable energy sources.
