Clyde Hydrogen Systems

What Clyde Hydrogen Systems does

Clyde Hydrogen Systems is a University of Glasgow spinout founded in 2022, developing modular green hydrogen production systems based on a patented decoupled electrolysis architecture. The technology separates hydrogen and oxygen generation into distinct stages using a proprietary liquid mediator solution, enabling non-gaseous energy storage and direct production of high-pressure hydrogen at 100+ bar without mechanical compression. The company claims up to 30% overall efficiency improvement versus conventional electrolyzers, inherent safety from eliminating hydrogen–oxygen mixing, and direct connectivity to intermittent renewable power without treated water inputs. Its product roadmap comprises three tiers — CLYDE-50 (100kW–500kW), CLYDE-500 (1–2MW), and CLYDE-1000 (2MW+ scalable to 50MW) — built from standardized Reductor, Storage, and Reactor modules, targeting applications in long-term energy storage, eFuel/SAF production, industrial hydrogen, and agriculture.

The company is pre-revenue and pre-commercial, with a fully integrated prototype completed in January 2026 and first certified commercial product targeted for mid-2028. Its go-to-market is enterprise field sales targeting industrial facilities, renewable energy site operators, and distributed hydrogen producers, complemented by a flagship MoU with PlusZero (Hebrides-based green hydrogen producer) that includes an option to purchase 10 MW of electrolyser capacity, and a strategic investment from Ecotricity providing real-world testing at UK renewable energy sites. Clyde Hydrogen has raised over £1m in pre-seed equity (Zinc-led, April 2024) plus approximately £700k in grants from the Scottish Government's Hydrogen Innovation Scheme and the Net Zero Technology Centre, closed a Pre-Seed2 round with Ecotricity (September 2025), and is currently raising up to £5m in seed funding. Leadership includes CEO James Peck (former ZeroAvia CCO), CTO Dr Matt Lees, CSO and co-inventor Prof Mark Symes, and Chairman Dr Jos Trehern.

Core offering

Clyde Hydrogen Systems develops and manufactures modular electrolyser systems based on its patented decoupled electrolysis technology for green hydrogen production. The portfolio includes three product tiers (CLYDE-50, CLYDE-500, CLYDE-1000) ranging from 100kW to 100MW+ capacity, using a liquid mediator that enables non-gaseous hydrogen storage and high-pressure output (100+ bar) without mechanical compression. The systems are designed for industrial facilities, renewable energy sites, eFuel producers, and agriculture applications.

Product overview

Clyde Hydrogen Systems offers a modular hydrogen production platform based on its proprietary decoupled electrolysis technology. The portfolio consists of three product tiers (CLYDE-50, CLYDE-500, CLYDE-1000) ranging from 100kW to 100MW+ capacity, built from three standardized modules: the Reductor (electrochemical reductor), Storage Module (liquid mediator tank), and Reactor Module (catalytic hydrogen generator). This modular architecture enables flexible system configurations for applications including long-term energy storage, e-fuel production, hydrogen production, and agriculture. The company targets commercial delivery starting with CLYDE-50 in mid-2028.
