Liquid Air Energy Storage System

In the power generation system, liquid air is pumped from the storage tank to the evaporator where it is heated from about 80 K to ambient temperature. This causes the liquid air to vaporize and build up 6.5 MPa of pressure. The high-pressure air is expanded through a 3-stage turbine with reheating to produce power.

Technology: Liquid Air Energy Storage

To recover the stored energy, a highly energy-efficient pump compresses the liquid air to 100-150 bar. This pressurised liquid air is then evaporated in a heat exchange process, cooling down to approximately ambient temperature, while the very low temperature (ca. -150 oC) thermal (cold) energy is recovered and stored in a cold accumulator.
