Compressed Air Energy Storage
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.Wild, Matthew, LWind Drives Growing Use of Batteries ''The New York Times'', July 28, 2010, p. B1. 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 global shift towards renewable energy renewed interest in CAES systems, to help highly intermittent energy sources like photovoltaics and wind satisfy fluctuating electricity demands.Lund, Henrik. The role of compressed air energy storage (CAES) in future sustainable energy systems. Energy Conversion and Management. One ongoing challenge in large-scale design is the management of thermal energy since the compression of air leads to an unwanted temperature increase that not only r ...
