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.

Peter Morice
Lead System Engineer (Paris)

I was born in France and grew up in the US. I did my undergraduate degree in Mechanical Engineering at Columbia University in New York City. After my undergrad, I worked in industry for nine years, most of that time in NYC at a small engineering consulting firm that specialized in automation and process controls for large industrial power generation, both electrical and steam.

I came to the realization a few years ago that my efforts in the power generation industry where not going to make the change that I felt was necessary to create a more sustainable future, so I applied to graduate programs to build new skills in electrochemistry and data driven modeling. This led me to MIT, where I did my master’s thesis in the BioInstrumentation Lab on the application of PEM electrolysis and the application of system identification tools and machine learning for system modeling.

Paul Wallace
Principal Process Engineer (Paris)

I have worked as a Chemical Engineer since 1980. I started working in the syngas generation and conversion area with Texaco, and Chevron for the first 24 years of my career. I then worked on developing syngas and hydrogen fueled turbines for GE for 2 years. I then worked for a series of companies developing coal gasification projects in the US.

When low cost natural gas from fracturing made coal uneconomic I switched fields to desalination. Over the last 16 years I developed a full recovery desalination process that monetizes all the minerals in seawater and other salty waters in addition to recovering all the water. This allowed me to collect the syngas and electrochemistry experience that was a perfect fit for Dioxycle.
