How Does LAES work?
1. Charge
2. Store 3. Discharge
1. Charge: Offpeak or excess electricity is used to power an air liquefier, which produces liquid air.
2. Store: The liquid air is stored in a tank(s) at low pressure.
3. Discharge: To recover power the liquid air is pumped to high pressure, evaporated and heated. The high pressure gas drives a turbine to generate electricity.

LAES: Technology Benefits
• LAES uses existing mature components (liquefier, liquid air storage, power turbine), with proven performance, cost, lifetime (25 year+).
• Suitable for large energy stores from about 20MWh to >1GWh, not restricted by geography.
• 60% efficiency in stand alone mode.
• Integrates well with other industrial process plant (utilising waste heat/cold) to enhance performance e.g. 70%+.
• Costs/economics improve with scale (50MW/200MWh <£1,000/kW <£250/kWh).
• Can be integrated at renewable site, but more valuable as a system resource for enabling wider renewable deployment.
• The system is ready for deployment at commercial scale (>5MW/15MWh) in industrial or utility applications.

2. Discharge: To recover power the liquid nitrogen is pumped to high pressure, evaporated and heated. The high pressure gas drives a turbine to generate electricity.
Liquid nitrogen trucked to site
1. Liquid Nitrogen Delivered: stored in tanks until required. Saves cost of liquefier.
