UK-based hydrogen technology firm Supercritical Solutions Ltd has completed a £14 million ($17.4 million) Series A funding round, co-led by Shell Ventures and Toyota Ventures. The investment will support the scaling of the company’s high-pressure, high-efficiency electrolyser technology aimed at decarbonising hard-to-abate sectors such as chemicals and fuels.
Supercritical’s patented membrane-less electrolyser is designed to produce green hydrogen at over 220 bar pressure with energy consumption as low as 42 kWh per kilogram of hydrogen. The company is targeting commercial deployment from 2027, and has now opened a waiting list for technology reservations.
The Series A round includes follow-on investment from seed investors Lowercarbon Capital and Anglo American Platinum, as well as new contributions from a global group of backers including Al Mada Ventures, Blackfinch Ventures, Kibo Invest, Niterra/Global Brain, TOP Ventures (Thai Oil), Earth Ventures, and Alumni Ventures.
With the latest investment, Supercritical aims to advance its technology to pilot scale in collaboration with selected partners. The company also intends to expand manufacturing capacity, enhance operations, and explore new market opportunities.
Toyota Ventures Principal Ethan Sohn said, “Supercritical’s membraneless electrolyser demonstrates promising energy efficiency, a critical factor in reducing the cost of green hydrogen.”
Al Mada Ventures Managing Director Omar Laalej noted the potential relevance of Supercritical’s technology in Morocco’s green hydrogen ambitions, particularly under the country’s “Morocco Offer” initiative.
Supercritical’s technology does not rely on membranes, iridium, PFAS chemicals, or rare earth elements, potentially reducing costs and environmental concerns associated with traditional electrolysis methods. The firm states that its electrolyser consistently delivers hydrogen with purity levels above 99%.
The company is now progressing toward the deployment of its pilot projects and has already secured several commercial commitments.
