The Ins and Outs of Compressed Air Energy Storage
As promising as compressed air appears as a storage medium, it does have some drawbacks. When air is compressed, it heats up. When it expands, it cools. Cold air isn''t as effective at producing power when it is run through a turbine, so before the air can be used, it needs to be heated, frequently using natural gas, which produces CO …
