Battery Storage Needed to Expand Renewable Energy
Storing energy remains the missing link for many clean power technologies, but DOE researchers and startup companies are racing to fill the gap.
Without a way to save electricity and heat for later use, intermittent renewable energy will struggle to close price and performance differences with fossil fuels. But stored energy has advantages. It can respond to increased power demands faster than a turbine can spool up, and it can also save excess power and then supply it when needed.
