Compressed air energy storage for offshore turbines | Windpower Monthly

This article was first published in WindMax, the quarterly technical data publication of Windpower Monthly. Click here to find out more. The first large-scale commercial plant was built in Huntorf in Germany and has now been in successful operation for many years. The reason for the slow progress of CAES is the prohibitive cost of a suitable storage vessel. Large CAES schemes have relied on disused underground caverns to provide a reservoir for the compressed air, but these are not readily available and may not be close to a market for electrical energy. Also, existing CAES plants are not environmentally "green". Compression of air into the storage reservoir generally relies on compressor power generated by fossil fuel, and recovery of stored energy uses conventional gas turbines burning fossil fuel. Even if the compressor power is provided by wind turbines, the plant is p...
