What 1s1 Energy does
1s1 Energy is a Portuguese-American materials science company developing proprietary boron-based membrane technology for PEM (Proton Exchange Membrane) water electrolyzers used in green hydrogen production. Founded in 2021 and headquartered in Portola Valley, California, the company targets hard-to-abate industrial sectors — primarily steel, chemicals and ammonia, utilities, and heavy-duty transport — by replacing legacy electrolyzer materials with novel boron-based chemistries that, per company claims, reduce electricity consumption by 20-30%, lower capital expenditure by approximately 50%, and extend stack durability to up to nine years. Two USPTO-granted patents (US 11,331,631 in 2022 and US 11,594,747 in 2023) protect the core chemistry.
The company operates a portfolio of revenue streams: hardware sales of next-generation electrolyzers built around its proprietary materials, technology licensing to electrolyzer and fuel cell OEMs, paid pilot project services with utility and industrial customers, and managed-services collaboration in green ammonia (notably with Nitrofix). It runs a sales-led, partnership-first go-to-market anchored by strategic pilots with major energy and industrial players including Enel Green Power and CSN, supplemented by academic collaborations with MIT, UC Berkeley, NREL, and the Max Planck Institute. Manufacturing is targeted at 300 MW of annual electrolyzer capacity, anchored by a €63 million IPCEI-approved project in Portugal, with a Lisbon laboratory opened in 2024 and a Campinas, Brazil laboratory opened in 2025 under wholly-owned subsidiary 1s1 Energy Brasil.

1s1 Energy product offering
Product offeringCore offering
1s1 Energy develops and manufactures proprietary boron-based electrochemical membrane materials and components used in PEM (Proton Exchange Membrane) water electrolysis systems for green hydrogen production. The company's products include ion-exchange membranes, catalysts, and complete next-generation electrolyzers, designed to deliver lower energy consumption, lower capital cost, and longer stack life than legacy electrolyzer technologies.
Product overview
1s1 Energy offers a unified portfolio centered on its proprietary boron-based electrochemical materials technology, which serves as the foundation for both next-generation electrolyzers and fuel cell components. The company's core product is its 1s1 Electrochemical Materials platform—a family of ion-exchange membranes and catalysts that replace legacy materials in hydrogen production and fuel cell systems. These materials enable electrolyzers with 20-30% lower energy consumption, 50% reduced capital costs, and up to 9 years of stack durability. The same material science underpins fuel cell component offerings, creating a cohesive technology stack addressing both hydrogen production and utilization.

1s1 Energy competitors and assessment
Company assessmentDirect peers
- McPhy Energy: French electrolyzer manufacturer specializing in alkaline and PEM technology for industrial and mobility hydrogen applications. Comparable European peer competing for the same industrial decarbonization customers.
- Ballard Power Systems: Canadian PEM fuel cell manufacturer with growing electrolyzer activity, serving heavy-duty mobility and stationary power customers. Overlaps with 1s1's fuel cell membrane materials ambitions and PEM technology focus.
- Ohmium International: US-based PEM electrolyzer manufacturer focused on modular, gigafactory-scale green hydrogen systems. Comparable to 1s1 in core PEM technology and target customers, though at a more advanced commercial stage with larger deployed base.
- Nel ASA: Norwegian manufacturer of PEM and alkaline electrolyzers for green hydrogen production. A leading commercial-scale competitor to 1s1 Energy in the same PEM electrolyzer category, though Nel relies on incumbent membrane technology rather than 1s1's boron-based chemistry.
- ITM Power: UK-based PEM electrolyzer manufacturer targeting large-scale green hydrogen production. Directly comparable to 1s1 in product category and customer base (industrial hydrogen users), with substantially more capital and commercial deployments.
- John Cockerill Hydrogen: Belgian manufacturer of alkaline and PEM electrolyzers for industrial-scale green hydrogen projects. Competes with 1s1 in serving steel, ammonia, and refining customers seeking decarbonized hydrogen supply.
- Sunfire: German electrolyzer developer using solid oxide (SOEC) and alkaline technologies for green hydrogen. Comparable to 1s1 as a European-based hydrogen technology company pursuing industrial-scale deployments, though with a different core electrochemical approach.
Broad incumbents
- Plug Power: Established hydrogen fuel cell and electrolyzer company serving material handling, transportation, and stationary power markets. Overlaps with 1s1 in PEM electrolyzer technology and green hydrogen end-markets but operates at much greater scale with broader product portfolio.
- Cummins (Accelera by Cummins): Through its Accelera segment, Cummins manufactures PEM electrolyzers (HyLYZER) and fuel cell systems for hydrogen production and mobility. A large incumbent competing with 1s1 in industrial-scale electrolyzer markets.
Emerging players
- Hydrogenious LOHC Technologies: German hydrogen storage company using liquid organic hydrogen carrier (LOHC) technology, complementary to 1s1's electrolyzer production and addressing the broader hydrogen value chain including storage and transport—relevant as an adjacent ecosystem player.
