Mantel is developing the first molten-salt-based carbon capture technology which is 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 industries to reduce emissions and achieve net-negative emissions. By solving for efficiency Mantel can cut costs substantially, unlocking carbon capture’s role in reaching net zero emissions by 2050.
