Hot rocks offer solution to grid-scale energy storage

A facility that uses the temperature difference between hot and cold rocks to store energy is being launched as part of a new research centre led by Newcastle University. The new National Facility for Pumped Heat Energy Storage will bring together the former Isentropic facility and Newcastle University’s Sir Joseph Swan Centre for Energy Research to create the world’s first grid-scale demonstration of pumped heat storage. Coupled to the electricity grid, the demonstration facility is said to include a 150kW heat pump and uses a reversible heat pump engine which converts electrical energy to heat. Taking excess electricity from […]
