New energy green electricity storage

Focuses on technologies and systems for storing energy, including batteries, thermal storage, and mechanical storage systems. By the end of this decade, the job of batteries and power electronics at large facilities will shift from break-glass insurance to weekly or almost daily. They store surplus renewable energy for when it's not windy or sunny, and maintain a balance between energy supply and demand. -manufactured battery technology overcomes the limitations of conventional lithium-ion in 3- to 12- hour intraday.
