There can be a single conversion of mechanical energy to pneumatic or hydraulic energy. Therefore, compressed air can have high energy efficiency when using mechanical renewable energy such as wind turbines or hydropower. Thermal energy to mechanical energy conversion is possible, but less efficient due to Carnot conversion inefficiencies. Thermal storage of heat from a renewable solar source is also possible using a phase change material such as a molten salt.
