Abstract
A system for energy storage, in particular for mechanical energy, including a system for quasi-isothermal compression of a gas via a hydraulic fluid. The mechanical energy stored is then released by quasi-isothermal expansion of the gas. The system is also configured to store electrical energy, in particular from intermittent sources such as photovoltaic or wind energy. The storage of excess electrical energy can also be considered for use during consumption peaks.
