About Dioxycle

Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency, starting with ethylene, the world's most used petrochemical. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing 1-2% of the world's emissions.

Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality by developing a completely novel technological approach. Having completed our medium-scale Proof-of-Concept, we are now working towards our first-of-its-kind industrial-scale electrolyzer and are assembling key partnerships for future commercial roll-out.

We are supported by world-class funders including Lowercarbon Capital, Breakthrough Energy Ventures, Gigascale Capital and Collaborative Fund and have raised $37m to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)
