The Dearman Engine is behind Highview Power’s 250MWh energy storage facility being built in Manchester. It will use excess electricity from the grid – say on a windy night with the turbines spinning – to compress air in giant tanks. These will then act as energy storage “batteries” and when electricity demand peaks they can open the valve, drive a Dearman engine and produce electricity. Energy storage technologies are vital on a grid ever more reliant on the vagaries of the sun and the wind and there’s strong interest in this technology based on the Dearman Engine from elsewhere in the UK, North and South America.
