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. .
