Mantel Receives Funding to Commercially Deploy Carbon Capture System

Mantel Capture Inc. raised $30 million from a Series A fund co-led by Shell Ventures and Eni Next for the demonstration of Mantel’s high-temperature carbon capture system at an industrial site for eventual commercial deployment.

The project will be able to capture 1,800 tonnes of CO₂ at the industrial site per year. The captured CO₂ will be compressed and stored underground or used for a variety of applications.

“For widespread adoption of carbon capture to be feasible, it must be cost effective,” said Hector MacQuarrie, principal at Shell Ventures. “Mantel’s innovative solution has the potential to significantly lower carbon capture costs and can be applied across diverse sectors, including natural gas power plants and hard-to-abate industries like cement, steel and chemicals.”

Mantel’s carbon capture solution uses a solvent to decrease the cost of capturing carbon, said Eni Next CEO Clara Andreoletti in the press release.

Molten borates, a high-temperature liquid-phase carbon capture material, is the only solution of its kind able to capture CO₂ at its source of emission. Mantel uses molten borates coupled with high temperatures to recover high grade heat when capturing CO₂ to offset the energy needed to regenerate molten borate.

The process reduces the cost of carbon capture by more than half compared to more traditional amine-based solutions.

The fund included investors Engine Ventures, New Climate Ventures, Hartree, BP Ventures, Arosa Ventures, Vale Ventures, Newlab and MCJ Collective, among others.
