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 SummaryMantel 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. 😅------------Join my EFI Climate CEO Peer Group:Become an EFI Climate CEO Fellow — North America’s top invite-only peer community for growth-stage CEOs in climate tech and sustainability. 100 CEOs and Mentors representing $40B in market value or investment assets.👉 https://www.entrepreneursforimpact.comGet my 4-Minute Newsletter: Climate CEOsFor entrepreneurs and investors: 5 quick ideas on climate data, CEOs to know, investor spotlights, AI insights, and mindfulness moments — drawn from lessons working with 400+ climate CEOs and investors, plus 25 years of meditation practice.👉 https://entrepreneursforimpact.substack.comLeave a Podcast Review.
