*** Relocated to the University of Birmingham’s Centre for Cryogenic Energy Storage. The pilot project was operated for four years before being donated to the University and Re-Commissioned at its new location on December 11, 2015.

Highview‘s technology uses off-peak or ‘wrong-time’ power to liquefy air (710 litres of air becomes one litre of liquid air), which is then held in a tank until electricity is required. The liquid air is then returned to gaseous form, expanding 710 times, to drive a turbine.

Extreme cold is recovered and stored to assist with subsequent liquefaction, thus greatly improving the overall efficiency of the system. If waste heat is available (e.g. from a neighbouring power plant or industrial process) then this can be introduced at the expansion phase, enhancing system efficiency.
