CAES is one of the 3 kinds of bulk storage that can store hours of excess intermittent power, but there are very few places to put them, they have very low efficiency, and are basically natural gas turbines that use less natural gas. There are just 2 in the world now, 110 MW in Alabama and 330 MW in Germany

Utility scale energy storage limited by minerals and geography

Preface. Natural gas is finite, but aside from (pumped) hydropower, natural gas is the main way wind and solar are balanced now. Therefore, a tremendous amount of energy storage will be needed in the future as natural gas declines. The … Continue reading
