The global transition to a low-carbon economy depends on technological breakthroughs that improve the efficiency and scalability of renewable energy solutions. A promising step in this direction has been taken in Scotland, where Clyde Hydrogen, a University of Glasgow spinout, has partnered with Hebrides-based green hydrogen producer and distributor, PlusZero, to demonstrate its innovative electrolyser technology in a real-world setting for the first time.

Decoupled Electrolysis: A Game-Changer

At the heart of this collaboration is Clyde Hydrogen’s decoupled electrolysis system, which represents a significant evolution in hydrogen production. Unlike conventional electrolysis, which generates hydrogen and oxygen simultaneously in the same location, Clyde Hydrogen’s system allows these gases to be produced separately, at different times and rates. This novel approach enhances safety, increases efficiency when paired with intermittent renewable energy sources, and reduces the need for mechanical compression to achieve high-pressure hydrogen output.

The Strategic Partnership

Under a Memorandum of Understanding (MoU), PlusZero will deploy one of Clyde Hydrogen’s commercial demonstrator electrolysers, overseeing its operation and testing for at least six months. This marks a crucial step in validating the technology beyond the laboratory, with the potential to establish Scotland as a leader in green hydrogen innovation. Additionally, PlusZero has the option to purchase an initial 10MW of electrolyser capacity, paving the way for further commercial adoption.

A Milestone for Clyde Hydrogen

For Clyde Hydrogen, this collaboration comes at a moment of technical and commercial validation. In December, the company achieved a breakthrough by producing hydrogen at pressures exceeding 100 bar in its Glasgow-based laboratory. This milestone, combined with the company’s ongoing funding round aimed at attracting up to £5 million in new investment, underscores the accelerating momentum behind its pioneering approach.

Scotland’s Hydrogen Vision

The partnership aligns with Scotland’s broader push to position itself at the forefront of the hydrogen economy. With funding from the Scottish Government’s Emerging Energies Technology Fund (EETF), PlusZero is advancing its first green hydrogen production facility at the Creed Hydrogen Skills and Innovation Centre in Stornoway. Scheduled to launch in October 2025, this initiative integrates commercial-scale hydrogen and oxygen production with research, training, and the testing of next-generation electrolyser technology.

James Peck, CEO of Clyde Hydrogen, emphasized the strategic significance of the agreement, stating, “To achieve a milestone technical breakthrough and already sign our first commercial agreement is a testament to the game-changing potential of our technology.” His optimism was echoed by PlusZero Founder and Managing Director, David Amos, who highlighted the transformative potential of the electrolyser, noting its “leap in cost efficiency and production flexibility.”

A Global Perspective

The implications of this partnership extend beyond Scotland. As the global hydrogen market evolves, scalable and cost-effective solutions are critical to replacing fossil fuels in hard-to-abate sectors such as heavy industry, transport, and power generation. By proving its viability in a commercial setting, Clyde Hydrogen’s decoupled electrolysis could serve as a model for future green hydrogen projects worldwide.
