“Sunamp has developed heat batteries, an idea which arose from an understanding that energy storage is at the heart of making renewables and energy efficiency work. There is over twice as much heat consumed in the world economy as electricity, so why isn’t heat storage a major topic? We decided that it was and that’s where we focus.” Andrew Bissell

CEO, Sunamp
