The "Grid Level Energy Storage Problem" Solar and wind provide "intermittent" electricity, meaning their energy production changes depending on the weather. People often need energy when the wind is not blowing or the sun isn''t shining, so we can end up with too much electricity at some times, and not enough electricity at other times.

Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.

Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the ...
