Dioxycle is a French-American climate-tech company building a low-temperature electrolyzer that turns waste CO2, water, and renewable electricity into sustainable ethylene - the world's most-used organic chemical - at a cost competitive with fossil-derived ethylene. Founded in 2021 by electrochemists Sarah Lamaison and David Wakerley, it aims to electrify chemical manufacturing and recycle industrial carbon emissions at gigaton scale.
Sarah Lamaison is the co-founder and CEO of Dioxycle, a Paris- and Bay Area-based climate-tech company building electrolyzers that turn industrial CO2 into ethylene and other chemicals using only water, electricity, and waste carbon. A chemist trained at Ecole Polytechnique, Cambridge, College de France, and Stanford, she turned her PhD on artificial photosynthesis into a company aiming to decarbonize one of the planet's dirtiest industries while staying cost-competitive with fossil feedstocks. She raised $17M in Series A funding led by Breakthrough Energy Ventures and Lowercarbon Capital, won the L'Oreal-UNESCO Young Talent award, and was named to Forbes 30 Under 30.
