Caldera is an ambitious Climate Tech start-up. We are the makers of the Warmstone heat battery which uses low carbon electricity whenever it is available to warm a solid core, storing this energy efficiently until the heat is needed. This solves a problem for millions of homes and businesses who want to decarbonise but have found that existing technologies are either very expensive or simply not viable. We are based in England and plan to licence globally.
