Mantel Capture, a provider of molten borate carbon capture systems, has raised USD 30 million in Series A funding co-led by Shell Ventures and Eni Next. This brings the company's total funding to USD 32.5 million.
The funds will be used to deploy a demonstration project at an industrial site that will capture 1,800 tons of CO2 emissions per year, 10x its lab-scale capacity. This project paves the way for full-scale commercial deployment of Mantel's high-temperature carbon capture systems. Other investors included Engine Ventures, New Climate Ventures, Hartree, bp Ventures, Arosa Ventures, Vale Ventures, Newlab, and MCJ Collective.
Founded in 2022, Mantel's proprietary technology uses molten borates to capture CO2 from industrial emissions sources and operates at high temperatures. This approach reportedly reduces capture costs by more than half compared to conventional amine-based carbon capture technologies, making it economically feasible for heavy industrial sites.
