The Long Duration Energy Storage program invests up to $330 million into the demonstration of non-Lithium-ion energy storage technologies and projects to implement long duration energy storage systems across California. The Long Duration Energy Storage program will pave the way for opportunities to foster a diverse portfolio of energy storage technologies that will contribute to a safe and reliable future grid.

This program plays an important role in achieving California's zero carbon goals. As California is accelerating the deployment of renewable energy sources to meet clean energy goals, it is creating an emerging need for storage technologies with extended energy-duration capabilities to maintain grid reliability. A major focus of the program is to support development of non-Lithium-ion energy storage technologies to foster diversity and competition in the market. As the grid continues to evolve to accommodate more renewable energy to meet decarbonization goals, the importance of long duration energy storage will continue to grow.
