Clyde Hydrogen Systems, AqSorption and Latent Drive are each set to receive £500,000 ($655,347) as part of the Net Zero Technology Centre’s (NZTC) 2024 electrolyser funding competition.
The energy hub initiative is designed to scale Scottish supply chains and establish an export market. Therefore, the NZTC pushed forward the development of prototypes to eventually pilot a project.
Up to 36 applications were received from around the globe for the funding, but just three UK-based electrolyser developers succeeded.
The University of Glasgow’s School of Chemistry spinout, Clyde Hydrogen Systems, boasts decoupled electrolysis technology which offers flexibility and opportunities “not possible with existing electrolysers.”
The process sees hydrogen and oxygen produced separately at different times and rates, “enhancing safety and reducing costs.”
Clyde’s technology also reportedly produces high-pressure hydrogen without mechanical compression and is highly compatible with intermittent renewable energy sources.
With £500,000 secured, Aqsorption’s high-pressure membrane-less electrolyser technology can be scaled further. The process is designed to be more efficient and operate at higher pressures than other technologies, with reduced maintenance costs.
The Nottingham-based firm’s membrane-less electrolyser design reduces reliance on expensive rare earth minerals. H2 View understands the system’s efficiency will be boosted by recapturing kinetic energy from the high-pressure oxygen output.
Latent Drive’s SeaStack technology encompasses a direct seawater-to-hydrogen process, with a “unique cell design to exploit the properties of seawater,” eliminating the need for desalination and purification of the feed water.

Essentially, the SeaStack can move hydrogen production offshore for close coupling to the energy supply at wind farms, capturing more wind energy at a lower cost.
The technology will be ideal for “severe environments at floating offshore wind platforms,” along with port installations for refuelling working vessels or port infrastructure.
“In Phase 1 of our Energy Hubs project, we identified an urgent need to accelerate the efficiency of electrolyser operation,” explained Darren Gee, ETF Programme Manager NZTC. “In Phase 2, we are taking action.”
Gee continued, “Together with key industry partners, we identified three groundbreaking UK technologies from a remarkably strong field of applicants.
“These technologies are scalable and have the potential to significantly push the boundaries of hydrogen production.
“By supporting technologies at an early stage of their development, we have an opportunity to drive this technology forward and make a direct impact on the future of green hydrogen production in Scotland.”
