HOW IT WORKS

Liquid Air Energy Storage

HOW LIQUID AIR ENERGY STORAGE SYSTEMS WORK

Our patented liquid air energy storage technology draws on established processes from the turbo machinery, power generation and industrial gas sectors.

Stage 1. Charging the system

An air liquefier uses electrical energy to draw air from the surrounding environment, the air is cleaned and cooled to subzero temperatures until it liquifies. 700 liters of ambient air become 1 liter of liquid air.

Stage 2. Energy store

The liquid air is stored in insulated tanks at low pressure, which functions as the energy reservoir. Each storage tank can hold a gigawatt hour of stored energy.

Stage 3. Power recovery

When power is required, stored heat from the charging system is applied to the liquid air via heat exchangers and an intermediate heat transfer fluid. This produces a high-pressure gas that drives a turbine and generates electricity.
