Our Mission

Fight climate change with breakthrough science.

The world is built on carbon bonds derived from an ever-depleting supply of fossil fuels that in turn produces an ever-increasing level of CO₂. Both of these issues may be addressed at once by converting carbon-based emissions back into the things we use everyday. Dioxycle was built on this idea and, with breakthrough advances and a DIY attitude, we develop electricity-driven pathways that convert waste carbon emissions into critical feedstocks more cheaply than ever before. 

The heart of this solution is Dioxycle’s electrolyzer technology that tears apart carbon dioxide and rebuilds it into energy-rich and useful molecules. Such a process can reenergize and reuse carbon dioxide and 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
Chemical Engineer (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.

Dr. Edward Malins
Head of Polymers (Paris)

I grew up in a leafy corner of rural Cambridgeshire before moving to the relatively built-up area of Warwick University to get my BSc in chemistry.

After that I spent two more years at Warwick University and then two years at Queen Mary University of London to get myself a PhD in polymer chemistry. My PhD was focused on the synthesis of new polymeric fuel additives.

Prior to Dioxycle, I worked for 5 years in the oil and gas industry. Here I designed new polymers and formulations to try and increase the efficiency of oil wells, because the world just can’t get enough oil.
