- Clean Power Hydrogen Plc (CPH2.L) develops and manufactures proprietary Membrane-Free Electrolyser (MFE) technology for green hydrogen and oxygen production. The company produces scalable electrolyser systems, including the MFE01 technology demonstrator (20kW, 6kg H2 per day), MFE30 (145kW, 60kg H2 per day), MFE110, and MFE220 (1MW, 450kg H2 per day); these systems employ a patented membrane-free stack combined with cryogenic separation to deliver pure, separated hydrogen and oxygen gases using renewable electricity inputs, targeting applications in power generation, industry and manufacturing, transport and machinery, commercial and retail, and hydroculture sectors. Founded in Ireland in 2012 by Dr. Nigel Williamson and Joe Scott, with its UK entity Clean Power Hydrogen Group Limited established thereafter, the company is headquartered at Unit D, Parkside Business Park, Spinners Road, Doncaster DN2 4BL, United Kingdom, and listed on the London Stock Exchange's AIM market since February 2022.
CPH2 operates primarily in the United Kingdom with international reach through licensing and partnerships, serving customers in energy, industrial, and mobility markets seeking zero-emission hydrogen solutions as alternatives to fossil fuels and PEM electrolysers. The technology emphasizes lower emissions, reduced operating costs, and robustness for mission-critical environments, including off-grid power, electric vehicle support, and grid-based storage; it has achieved certifications such as ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, CE Marking for its stack, and Fit for Hydrogen status.
In recent developments, CPH2 raised £7.4 million in 2025 through a placing, subscription, and retail offer to advance commercialization of its membrane-less technology, following a proposed fundraising announced in July 2025 with operational and strategic updates. The company secured a new licence agreement and purchase order with Hidrigin in November 2024, activated its first licensed manufacturing partnership with Hidrigin in June 2025, and shipped its Membrane-Free Electrolyser to Belfast, completing all site acceptance tests by May 2025. Additional milestones include a June 2025 MOU with Constant Energy, a December 2024 partnership with EnerHy CDT for high-efficiency electrolysers using renewables, and appointments such as Richard Scott as Chief Commercial Officer in April 2025; earlier efforts encompassed joint ventures in Northern Ireland, deliveries of Ireland's first electrolyser, and manufacturing agreements with Fabrum Solutions.
