Critical Need:

Stationary electrical energy storage plays several important roles in the U.S. electricity system, and these are expected to grow as the grid continues to evolve. Long-duration energy storage systems address grid needs beyond those covered by daily cycling. Such systems could provide backup power for several days, improving grid resiliency, or allow for the integration of even larger amounts of intermittent renewable sources like wind and solar. In the near term, such systems could help shape the output from individual wind and solar installations, improving the reliability of these resources and thus greatly increasing their value to the grid.

Project Innovation + Advantages:

The RedoxBlox team will lead the engineering and development of a pilot-scale energy storage platform comprising a thermochemical energy storage module integrated with a gas turbine power generator. In addition, the team will conduct advanced materials and component-level investigations, including a comprehensive analysis of their core thermochemical energy storage material that enables this energy storage technology. Test data collected from intermediate-scale thermal energy storage modules will be used to inform the design, operating parameters, and component selection of the final, integrated, pilot-scale system. This project paves the way for low-cost, long-duration, stationary electrical energy storage that will support grid infrastructure, enhance grid resiliency, and enable a greater share of intermittent renewable resources into the electrical power generation mix.

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.
