British start-up Caldera is launching a new large-scale domestic heat battery, capable of providing low carbon heat by utilising excess renewable energy on the grid. The battery is based around its patented technology Warmstone, which can be heated overnight using cheap, green, off-peak electricity. It then discharges heat throughout the day to power heating and hot water. As well as offering an alternative path to decarbonisation, especially for off-gas grid homes, the flexible technology could be used for demand side response, in a similar fashion to electric vehicles and domestic battery storage systems.
