What Dioxycle does

Dioxycle is a Paris-headquartered, French-American climate-tech company founded in 2021 that has developed a proprietary carbon electrolyzer platform for converting industrial carbon emissions (CO and CO2) into sustainable commodity chemicals. The electrolyzer uses low-temperature electrolysis in which stacked plates distribute COx gases across catalytic cores that are supplied with renewable electricity, producing drop-in chemicals — ethylene, formic acid, sulfuric acid, and caustic soda — that are chemically identical to their fossil-derived counterparts and integrate into existing downstream supply chains without infrastructure changes. The company is targeting end-markets including consumer goods (packaging, textiles, footwear), mining (ore-leaching acids and refining bases), energy infrastructure (battery and fertilizer inputs), agriculture (silage and feed additives), and pharmaceuticals (low-carbon building blocks).

Dioxycle's revenue model centers on enterprise B2B sales of these electrolyzer-produced chemicals through direct field sales and multi-year offtake agreements with industrial chemical buyers; its flagship commercial relationship is a multi-year partnership with L'Oréal Groupe to supply carbon-derived ethylene for polyethylene packaging supporting L'Oréal's 2030 sustainability targets. The company also engages in thought-leadership-driven top-of-funnel marketing via conference participation (World Economic Forum Davos, EU Cleantech Conference, Aspen Ideas Climate) and earned media, while pursuing distribution leverage through chemical industry partnerships (Brenntag).

The company has raised $40 million in cumulative funding led by Lowercarbon Capital and Breakthrough Energy Ventures Europe (with Gigascale Capital, BPI France, and France 2030 as additional backers), employs 11-50 staff across Paris and the San Francisco Bay Area, and is currently building toward first on-site demonstrators and industrial prototypes. Its leadership team combines deep electrochemistry and fuel-cell expertise with commercial experience drawn from DuPont, Chevron, Symbio, Plug Power, Giner, Foster Wheeler, and ENGIE, and has earned recognition including the Global Cleantech 100 (2026), Norrsken Impact/100 (2025), and a first-place finish in Fluor Corporation's Energise The Future 2026 startup competition.

Core offering

Dioxycle develops and operates a proprietary carbon electrolyzer platform that uses low-temperature electrolysis powered by renewable electricity to convert industrial COx emissions (CO and CO2) into drop-in sustainable chemicals, including ethylene, formic acid, sulfuric acid, and caustic soda. The platform consists of stacked plates that distribute COx gases to catalytic cores, which use electrical power to convert the gases into virgin-quality chemical outputs that displace fossil-derived equivalents. The company sells these chemicals directly to industrial buyers in mining, energy infrastructure, pharmaceuticals, agriculture, and consumer goods.

Product overview

Dioxycle offers a proprietary carbon electrolyzer platform that converts industrial carbon emissions (CO and CO₂) into sustainable chemicals. The core platform consists of stacked plates that distribute COₓ gases to catalytic cores, which use electrical power to transform emissions into valuable feedstocks. The company's product portfolio includes three main chemical outputs: Ethylene (the world's most used organic chemical used in textiles, packaging, medical devices, and PVC pipes), Formic Acid (used in agriculture, pharmaceuticals, and industrial applications), and Sulfuric Acid/Caustic (foundational chemicals for mining and manufacturing). These products are designed as drop-in replacements for fossil-derived chemicals, offering identical performance at potentially lower cost with a reduced carbon footprint.

Recent moves6 records

Expansion highlights6 records

Direct peers

• Twelve: Twelve (formerly Opus 12) is a US-based electrochemical CO2-to-chemicals company producing fuels and materials from captured carbon. It is the closest direct competitor to Dioxycle, sharing the same core thesis of converting COx into drop-in chemicals via electrolyzer technology.
• Sunfire: Sunfire is a Germany-based electrolyzer company producing e-fuels (e-kerosene, e-diesel) and renewable chemicals via high-temperature co-electrolysis. It is a direct peer in the electrolyzer-to-chemicals category, though focused on fuel outputs versus Dioxycle's chemical focus.
• LanzaTech: LanzaTech uses gas fermentation to convert CO and CO2 into fuels and chemicals, including sustainable aviation fuel and ethylene. It represents the leading alternative CCU pathway to electrochemistry, targeting the same industrial chemical buyers as Dioxycle.

Emerging players

• Avantium: Avantium is a Dutch renewable chemistry company developing plant-based alternatives to fossil-derived chemicals and plastics (e.g., PEF). It competes for the same downstream customers seeking low-carbon chemical inputs, but via a biomass rather than CO2-utilization pathway.
• Carbon Engineering (1PointFive): 1PointFive (the DAC arm of Occidental's acquisition of Carbon Engineering) supplies atmospheric CO2 at scale for utilization or sequestration. It is an enabling participant in the CCU ecosystem and could become either a supplier or competitor depending on integration strategy.

Others

• Climeworks: Climeworks is a direct air capture company that supplies concentrated CO2 for utilization or sequestration. As an ecosystem enabler, it could supply feedstock to CCU players like Dioxycle but does not directly compete in chemicals manufacturing.

Broad incumbents

• Nel ASA: Nel ASA is an established electrolyzer manufacturer primarily focused on green hydrogen production. While not a direct chemical producer, its alkaline and PEM electrolyzer platforms represent broad-incumbent competition for industrial decarbonization capital and partnerships.
• ITM Power: ITM Power is a UK-based PEM electrolyzer manufacturer supplying green hydrogen infrastructure. It is a broad-incumbent in the electrolyzer space and could expand into adjacent COx-to-chemicals applications, but is currently focused on hydrogen production.
• Thyssenkrupp Nucera: Thyssenkrupp Nucera is a German industrial electrolyzer company specializing in alkaline water electrolysis for green hydrogen. It is a broad incumbent that could leverage its scale to enter adjacent COx electrolysis markets; notably, Dioxycle has hired engineers from its R&D team.
• Topsoe: Topsoe is a Danish catalysis and process technology company developing power-to-X solutions including electrolysis-based fuels and chemicals. It is a broad incumbent with overlapping R&D capabilities in COx conversion, serving similar industrial chemical customers.
