Cameron Halliday

Cameron Halliday is the co-founder and CEO of Mantel, a Cambridge, Massachusetts climate-tech company spun out of MIT's chemical engineering labs. Mantel uses molten borate salts to capture CO2 from heavy industry at high temperatures, recovering most of the energy as usable steam and slashing the cost and energy penalty of carbon capture. Halliday discovered the core material during his PhD at MIT, then co-founded the company in 2022 and raised a $30 million Series A co-led by Shell Ventures and Eni Next.
