Components and Operational NecessitiesThe primary components of a conventional CAES plant cycle include a motor/generator with pulleys on both ends (to engage/disengage it to/from the compressor train, expander train, or both).Multistage air compressors with intercoolers, which reduce the required power during the compression cycle, and an aftercooler, which reduces the required storage volume play a vital role in energy storage.More items [pdf]
[FAQS about Important equipment for compressed air energy storage]
The general principle, which has already been adopted at a few sites around the world, is essentially a matter of using surplus electric power to compress air, which is then stored in an underground cavern. When power needs to be made available, the air is released through a gas turbine. .
The two largest compressed air stores in the world are in Germany and the USA. They are underground chambers created in salt formations. But these plants lose a large proportion of the potential energy of the compressed air, because they do not incorporate a system. .
According to Perillo, there is only a single requirement as regards the choice of site. Large hollow spaces must already exist, as it would be too. .
The SINTEF researcher is himself a materials scientist. In this EU project he is responsible for SINTEF’s research and development efforts. .
