Energy Storage - 9: Richard Riley, Highview
Highview Enterprises is developing a Liquid Air Energy Storage (LAES) technology aimed at providing efficient energy storage solutions. The LAES system can operate at a scale from 20 MWh to over 1 GWh, with a demonstrated efficiency of 60% and potential integration with renewable energy sources. A pre-commercial demonstrator funded by UK government aims to showcase economic performance and reliability at a site near Manchester.

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.

- 9. © Highview EnterprisesLimited, 2015 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. 350kW/ 2.5MWh 20MW/ 80MWh 50MW/ 200MWh 500MW/ 2,000MWh
