Overview
Dioxycle recycles carbon emissions into ethylene by using an electrolyzer installed downstream of emission sources and powered by renewable energy. The captured carbon is converted into ethylene, which can be used to produce items like polyester fibers, plastics, pipes, and window frames. Its approach is deployed on-site at industrial emitters, aiming to reduce CO2 while producing a high-value feedstock and revenue from both equipment and ethylene. The goal is to help industries decarbonize by turning waste carbon into affordable ethylene, offering a scalable, practical solution for global emission reductions.

Simplify's Take
What believers are saying
- Secured multi-year offtake with L'Oréal in 2026, validating commercial demand for carbon-electrolyzed ethylene.
- Raised $17 million led by Breakthrough Energy Ventures to scale from lab to commercial deployment.
- Targets global high-emission clients in France and US, aligning with EU FOAK cleantech support priorities.
What critics are saying
- Lack of patent protection may let fossil incumbents replicate Dioxycle's low-cost CO2-to-ethylene process.
- High energy cost volatility in France could erase zero-to-negative green premium and reduce adoption.
- L'Oréal partnership is limited to packaging, not scalable to bulk ethylene markets, restricting revenue growth.
What makes Dioxycle unique
- Dioxycle uses a proprietary low-temperature electrolyzer to convert CO2 into ethylene without fossil fuels.
- The technology is a drop-in retrofit for existing plants, enabling Scope 3 reduction without workflow disruption.
- It offers zero-to-negative Green Premium, delivering cost-competitive ethylene versus conventional fossil-based production.

On 19th May, Dioxycle's Head of Strategy, Joseph Cordonnier, was in Brussels representing Dioxycle at the 2026 Cleantech Conference. Decarbonising industry is increasingly recognised as key to economic resilience and strategic autonomy. The question is: how? Dioxycle shared why critical chemicals are a strategic priority for European industry, what Dioxycle is building, and why Dioxycle believe Europe needs to focus support on FOAK projects for cleantech where Europe can become the leader. Dioxycle is proof of how innovation leads to scalable next-generation technologies that are cleaner, cheaper and sovereign. A warm thank you to CINEA - European Climate, Infrastructure and Environment Executive Agency and the Directorate-General for Climate Action (DG CLIMA) for the opportunity! Past: May 12 - 2026
