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.
Twelve is a carbon transformation company that uses an electrochemical reactor to turn captured CO2, water, and renewable electricity into the same chemicals and fuels usually drilled out of the ground - including E-Jet, a drop-in sustainable aviation fuel. Founded by Stanford-trained electrochemists, it is building the first industrial-scale CO2 electrolyzer plant in Moses Lake, Washington.
