Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project has been built in Huntorf, Germany, and is still operational. The Huntorf plant was initially developed as a load balancer for fossil fuel-generated electricity, the gl

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
