Carbon-Captured eNaphtha Marks Commercial Milestone for Sustainable Feedstock Supply Chains

## Carbon-Captured eNaphtha Reaches Commercial Scale in Landmark Supply Deal Sacramento-based electrofuels producer Infinium has announced a commercial supply agreement with Swiss sportswear brand On, providing the CO₂-derived eNaphtha feedstock behind what is being described as the world's first EVA foam midsole manufactured from captured carbon emissions at commercial scale. According to a PR Newswire release dated 16 July 2026, Infinium's eNaphtha — produced by converting captured carbon dioxide and renewable energy into a hydrocarbon feedstock — serves as the renewable input enabling On's new Cloud X 5 shoe to incorporate recycled carbon chemistry into its foam compound. The announcement represents a significant step in demonstrating that electrofuel-derived feedstocks can move beyond pilot programmes into genuine commercial production volumes. ### Relevance to Maritime and Energy Sectors While the immediate application is in consumer goods, the development carries meaningful implications for the broader maritime and energy transition landscape. Infinium operates within the same electrofuels technology ecosystem that is being closely watched by the shipping industry as a potential pathway to scalable, low-carbon marine fuels — including e-methanol, e-ammonia, and synthetic hydrocarbons. The ability to supply eNaphtha at commercial scale to an industrial customer demonstrates that the underlying production infrastructure for Power-to-X fuels is maturing. For shipowners and fuel buyers tracking the readiness of alternative fuel supply chains, milestones of this nature provide evidence that electrofuel producers are advancing beyond demonstration-phase output. Infinium has previously positioned itself as a supplier of electrofuels for hard-to-abate sectors, and its technology platform — which uses renewable electricity and captured CO₂ as primary inputs — aligns closely with the feedstock chemistry relevant to marine synthetic fuel production. ### Broader Context The announcement comes as the International Maritime Organization's revised greenhouse gas strategy continues to drive demand signals for low- and zero-carbon fuels across global shipping. Fuel producers capable of demonstrating commercial-scale delivery of CO₂-derived products are increasingly attractive partners for energy majors, port authorities, and shipping companies seeking to secure future fuel supply agreements. While eNaphtha for foam production and e-fuels for marine propulsion represent distinct end markets, they share common production pathways and infrastructure requirements. Commercial traction in adjacent industries can accelerate investment, reduce costs, and validate the broader electrofuels value chain. Infinium has not yet announced specific maritime fuel supply agreements in connection with this development. Further details on the company's production capacity and supply terms were not disclosed in the initial release.
