The material solution to carbon capture.

The Tough Tech problem we are solving

With increasing awareness of the impacts of climate change, there’s a growing urgency to reduce greenhouse gas emissions, particularly CO2. Carbon capture offers a pragmatic way to mitigate emissions from industries that are difficult or expensive to decarbonize in other ways. Mantel is developing the most thermally efficient and lowest cost carbon capture technology that will enable future energy resilience and security. By capturing CO2 at high temperatures, the energy generated on capture can be efficiently recovered and re-purposed. Mantel’s molten borate technology goes further, by making carbon capture profitable with existing incentives. Our approach enables industry to achieve ambitions climate goals without breaking the bank, unlocking carbon captures role in the energy transition.

About our solution

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 even 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.
