Carbon Capture: $32M Invested, 50% Lower Costs, MIT Tech [👏 Interview]

Discover why Shell, Eni, and MCJ invested in this molten borate carbon capture tech led by an MIT PhD.

🎧 Episode Summary

Mantel Capture is a Boston-based climate technology company developing the first molten-salt (molten borate) carbon capture system designed to operate at the high temperatures found inside boilers, kilns, and furnaces.

Their technology cuts the energy penalty of carbon capture by recovering useful heat (steam or electricity) and can reduce costs by roughly half compared with conventional systems.

Mantel raised $30 million in Series A funding, led by Shell Ventures and Eni Next, to deploy a demonstration plant at a pulp & paper mill that will capture around 1,800 tons of CO₂ per year.

Cam Halliday holds multiple degrees from MIT, including a PhD in Chemical Engineering, an MS in Chemical Engineering, and an MBA from MIT Sloan.

Originally from the UK, he co-founded Mantel in 2022 after years of carbon capture research in MIT’s Hatton Lab.

You’ll also be lulled into submission by his very sophisticated British accent, especially in contrast to my Southern drawl. 😅
