Mantel is developing the first molten-salt based carbon capture technology. Our molten borates are designed to operate at the high temperatures found inside boilers, kilns, and furnaces – enabling highly efficient carbon capture that has not been possible until now. Carbon capture can be applied across industry to reduce emissions - and even achieve net-negative emissions. By solving for efficiency Mantel can reduce energy losses by more than 60% and cut costs in half, unlocking carbon capture’s role in reaching global net zero.
