Clyde Hydrogen’s revolutionary technology uses a decoupled electrolysis process which aims to make using hydrogen as an alternative to fossil fuels significantly safer, simpler and cheaper in comparison to conventional systems available today. Crucially, Clyde Hydrogen’s system can be connected direct to renewable power and store the hydrogen in a non-gaseous form, solving many of the industry’s biggest obstacles and offering a real solution to long-term energy storage.
Last year, Clyde Hydrogen achieved an important technical breakthrough when it produced hydrogen at high pressure via its innovative decoupled electrolysis process for the first time. Now with the launch of its first fully integrated prototype system, Clyde Hydrogen will focus on scaling up to a commercial demonstrator, with the first market-ready product targeted for release in 2028.
Clyde Hydrogen is a spin-out from the University of Glasgow’s School of Chemistry, a global leader in electrochemistry research, and is confident its technology will redefine the architecture for the next generation of dependable green hydrogen production systems. The business will now focus on securing up to £5m of seed funding with the round expected to close by the end of Q2. This funding will enable the business to develop the first commercial product and expand its team to meet the growing demand for its hydrogen technology.
Clyde Hydrogen is backed by pre-seed funding from Zinc, the University of Glasgow and Dale Vince’s Ecotricity, alongside grants from the Scottish Government’s Hydrogen Innovation Scheme (HIS) and the Net Zero Technology Centre (NZTC). In 2025, Clyde Hydrogen also signed a memorandum of understanding (MoU) with Hebrides-based green hydrogen producer and distributor, PlusZero, to demonstrate its groundbreaking decoupled electrolyser technology for the first time outside of the laboratory.
James Peck, CEO of Clyde Hydrogen, commented: “I’m incredibly proud of the team in completing the build of our first fully integrated prototype. It’s a massive moment for the business and will allow us to show potential investors and customers that our technology is here and offers a real shift in the way hydrogen is produced and utilised. We will now focus on finding the right partners for the next stage of our growth journey as we move towards demonstrating the benefits of our revolutionary technology within a real world application.”
Professor Mark Symes, Co-Inventor of the technology, commented: “The journey from my first tiny-scale experiments in glassware with cobbled-together equipment to the expertly engineered system that the Clyde Hydrogen team has created has been quite simply staggering. While there have been many highs and lows typical of any pioneering startups wishing to challenge the status quo, today’s news marks a pivotal moment for the business as we make hydrogen from our integrated prototype for the first time. We will now push on from here to make an integrated end-to-end system for field trials and sales, and I’m confident that Clyde Hydrogen’s unique technology will prove to be a revolution for the production of green hydrogen.”
