Our Mission

Fight climate change with breakthrough science.

Dioxycle was built on the idea that with breakthrough advances and a DIY attitude, we can develop electricity-driven pathways that convert waste carbon emissions into critical feedstocks cheaper than ever before. 

The heart of this solution is Dioxycle’s electrolyzer technology that tears apart carbon emissions and rebuilds them into energy-rich and useful molecules. Such a process unlocks pathways to 100% sustainable fuels or 100% sustainable everyday chemicals, with no further accumulation of CO₂ in the atmosphere.

The team is uniquely positioned to develop and optimize this electrolyzer thanks to their unparalleled grasp of the required scientific and engineering innovations. The company combines 25 years of expertise in fuel cell technology with decades of combined experience in carbon dioxide chemistry, battery science and material science, in a group comprised of 80% PhDs and 8 nationalities. The result is an accelerated rate of technological scale up with continuous improvements to conversion efficiency.

Efficiency and scale are the company’s watchwords; Dioxycle’s plan is to ultimately recycle over 600 megatonnes of carbon dioxide each year and the larger and more energy efficient our process is, the faster we’ll get there.

This philosophy is now in practice in both of Dioxycle’s entities, based in Paris, France and the Bay Area, California. See our Career page for job openings.

Dr. Fanny Bétermier
Project Manager (Paris)

I grew up in Paris suburb (Bourg-la-Reine) and I lived in France and Australia.

I graduated from Centrale Paris (Biotech Engineering) and also completed a Master in Organic Chemistry of Université Paris Saclay.

Prior to Dioxycle, I did a PhD in Batteries at Collège de France and worked on how we could mimic self-healing mechanisms from nature to extend batteries cycling lives. That is when something clicked and I got convinced that chemistry could play a major role in the energy transition.
