Scottish startup Clyde Hydrogen has reportedly produced hydrogen continuously for the first time from its prototype decoupled electrolysis system.
Clyde’s beta technology uses decoupled electrolysis – splitting water into two stages with an electrochemical reduction and catalytic generator – to flexibly produce high-pressure hydrogen, even when renewable power isn’t available.
At its headquarters, the University of Glasgow’s School of Chemistry spinout said it “successfully” ran the beta version of its system to produce hydrogen at >100 bar continuously, although it was still under manual control.
A full pilot system is now expected later this year, and a commercial demonstration system is planned for 2027.
Under a Memorandum of Understanding with PlusZero, Clyde agreed to showcase its electrolyser technology outside the laboratory. Furthermore, the firm has launched a new funding round aimed at attracting £5m in investment to develop a production-ready system in 2026.
The startup has already been backed by pre-seed funding from Zinc, the University of Glasgow and grants from the Scottish Government’s Hydrogen Innovation Scheme (HIS) and the Net Zero Technology Centre (NZTC).
James Peck, the company’s CEO, said the latest milestone gives Clyde the confidence to begin building the full prototype in preparation for a commercial pilot project.
