What CPH2 does
CPH2 (Clean Power Hydrogen plc) is a UK-headquartered, AIM-listed technology company that has developed and commercialised a proprietary Membrane-Free Electrolyser (MFE) platform for green hydrogen production. The technology eliminates the proton-exchange membrane, platinum, iridium, and per- and polyfluoroalkyl substances (PFAs) used in conventional electrolysers — components the company identifies as over 50% of traditional capital cost — and uses cryogenic separation to produce hydrogen at >99.999mol% purity and oxygen at 99.7wt% (medical grade) from a single process. The product range spans the MFE01 (20kW demonstrator), MFE30 (145kW), MFE110 (scaled demonstrator), and the flagship MFE220 (1MW, ~450kg H2/day), with front-end engineering design underway for a 5MW scale unit.
The company historically generated revenue through direct hardware sales and is transitioning to a capital-light IP licensing model, evidenced by 20-year exclusive manufacturing licences (Hidrigin in Ireland, up to 2GW; Fabrum in Australia/New Zealand; Kenera in Germany/Scandinavia/Middle East) and assessment MoUs (Koch Modular for up to 100MW in North America, ABE Gruppe for 175MW in Germany, Siemens for joint development). Target verticals include wastewater treatment, data centre backup power, semiconductor production, life sciences and healthcare, renewable energy developers, and heavy-duty mobility. The business holds ISO 9001/14001/45001 certifications, CE Marking, Fit for Hydrogen status, the London Stock Exchange Green Economy Mark, and six patent families across 11+ jurisdictions.
In May 2026, an incident during final factory acceptance testing of the MFE220 1MW unit at the Rossington facility caused irreparable damage to the unit, prompting AIM trading suspension, the cessation of direct manufacturing, and a strategic pivot to technology development and IP licensing. As of June 2026, the company has signed a binding term sheet with Hidrigin for a £750,000 convertible loan note and a nine-month exclusivity period covering the UK, Ireland, US, Canada, and Mexico, contingent on closing a £3m+ equity fundraise.

Product offeringCore offering
CPH2 (Clean Power Hydrogen plc) develops and manufactures Membrane-Free Electrolyser (MFE) systems for green hydrogen production. Its MFE technology splits water into hydrogen and oxygen without using expensive platinum, iridium, or PFAs ("forever chemicals"), and is optimized for variable renewable electricity loads from wind and solar. The company sells electrolyser hardware (MFE220 1MW, MFE110, MFE30 units), licenses its MFE intellectual property to manufacturing partners globally (Hidrigin in Ireland, Fabrum in Australia/NZ, Kenera in Europe/Middle East, Koch Modular in North America), and provides associated service and maintenance contracts. Following a May 2026 testing incident, CPH2 has ceased manufacturing and is transitioning to a capital-light IP-led licensing model.
Product overview
CPH2 (Clean Power Hydrogen) offers a portfolio of Membrane-Free Electrolyser (MFE) products for green hydrogen production. The product line spans from the MFE01 (20kW proof-of-concept demonstrator) through the MFE30 (145kW commercial unit) and MFE110 (scaled demonstrator) to the flagship MFE220 (1MW system producing ~450kg H2/day). The proprietary technology eliminates the need for expensive membranes and precious metals, achieving 99.999% hydrogen purity and medical-grade oxygen output. Following a testing incident in May 2026 that caused irreparable damage to the MFE220, the company ceased manufacturing activities and transitioned to a capital-light, IP-led licensing model focused on technology development and licensing its intellectual property to manufacturing partners.

CPH2 competitors and assessment
Company assessmentDirect peers
- Nel ASA: Norwegian electrolyser manufacturer producing PEM and alkaline hydrogen generators at megawatt scale, serving similar industrial, mobility, and renewable energy customers. Directly comparable in product category (electrolyser hardware for green hydrogen) and target verticals, but with a much larger balance sheet and operational scale.
- ITM Power: UK-based PEM electrolyser manufacturer listed on AIM, producing megawatt-scale green hydrogen systems for industrial, transport, and energy applications. Directly comparable as a UK-headquartered electrolyser business on the same AIM market serving overlapping customer segments.
- Thyssenkrupp nucera: German-listed supplier of alkaline and PEM electrolysers for large-scale green hydrogen production, particularly in chlor-alkali and industrial markets. Directly comparable in offering large-scale hydrogen production equipment to industrial customers, but with substantially greater resources and commercial track record.
- Plug Power: US-based PEM electrolyser and fuel cell company with end-to-end green hydrogen solutions across mobility, material handling, and stationary power. Comparable in producing PEM electrolysers for green hydrogen and competing for similar end markets, including data centres and industrial customers.
- McPhy Energy: French electrolyser manufacturer specialising in alkaline and PEM hydrogen production equipment for industrial, mobility, and energy applications across Europe. Comparable as a dedicated green hydrogen equipment vendor targeting similar industrial verticals and decarbonisation customers.
- John Cockerill: Belgian industrial group with a hydrogen business producing alkaline electrolysers at multi-megawatt scale for industrial and renewable energy customers globally. Comparable as a large-scale electrolyser manufacturer with established industrial customers and global project pipeline.
Broad incumbents
- Siemens Energy: Global energy technology incumbent with a PEM electrolyser product line (Silyzer) and broad hydrogen generation portfolio addressing industrial, utility, and renewable energy customers. CPH2 even has a partnership MoU with Siemens plc; they are both active in scaling high-purity hydrogen production but Siemens operates at vastly greater scale.
- Cummins / Accelera (Hydrogenics): Accelera by Cummins is the hydrogen technology arm of Cummins Inc., offering PEM and alkaline electrolysers for utility-scale green hydrogen production alongside fuel cells. Overlaps with CPH2 in electrolyser hardware targeting industrial decarbonisation, but as part of a much broader powertrain and energy portfolio.
Emerging players
- Enapter: Germany-based manufacturer of small-scale anion exchange membrane (AEM) electrolysers targeting decentralised and residential hydrogen production. Comparable as an alternative-architecture electrolyser challenger to traditional PEM/alkaline systems, competing for distributed hydrogen use cases overlapping with CPH2's wastewater, healthcare, and small industrial segments.
- Hysata: Australian electrolyser start-up commercialising a novel capillary-fed electrolysis architecture claiming very high efficiency. Comparable as an emerging challenger in electrolyser technology targeting industrial green hydrogen at scale, with potential to compete with CPH2 in efficiency-led differentiation and partner with Australian/NZ licence-type partners.
