Mantel Capture is developing the first molten-salt-based carbon capture technology designed to operate at the high temperatures inside boilers, kilns, and furnaces. Its system uses molten borates and has demonstrated carbon capture at lab scale of about 0.5 tonnes per day. The company plans a demonstration project at an industrial site that is roughly 10 times larger than the lab tests and is rated to capture about 1,800 tonnes of CO2 per year. Funding from the recent round will be used to implement that demonstration and to pave the way for full-scale commercial deployment of its high-temperature capture systems. Mantel positions its approach as enabling higher efficiency and substantial cost reductions, which it says can unlock broader deployment of carbon capture and help reach net-zero emissions by 2050. The company is based in Boston, MA.
