What Supercritical does
Supercritical Solutions Ltd is a UK-based deep-technology company founded in 2020 as a spinout from Deep Science Ventures, headquartered in London with an engineering and demonstration facility at the Wilton Centre in Teesside. The company has developed and patented a supercritical water electrolysis system — a membraneless electrolyser cell operating at elevated temperature and pressure — that produces green hydrogen directly at up to 220 bar with up to 99.999 mol% purity and energy demand as low as 42 kWh/kg H2 (>90% Higher Heating Value stack efficiency). The architecture eliminates hydrogen compressors, iridium, rare earth metals, and PFAS chemicals from the design, and uses mass-manufactured industrial metals in an all-metal, end-of-life recyclable stack. Its Teesside 1 (TS1) demonstrator achieved Technology Readiness Level 5 in 2024.
The company sells proprietary high-pressure electrolyser systems to enterprise industrial customers in the chemicals, ammonia, methanol, refining, distilling, mining, and heavy transport sectors, with first commercial deliveries targeted for 2027 and a public capacity reservation waiting list. Revenue today is limited to paid feasibility studies (e.g., a January 2026 non-exclusive collaboration agreement with Shell Global Solutions International) and government grants, including £2.94M from DESNZ for the WhiskHy whisky-distilling project with Suntory Global Spirits and AUD 1.5M (GBP 800,000) from the Australia-UK Renewable Hydrogen Innovation Partnership for the HAMR Energy methanol study. The £14M Series A closed in late 2024 was co-led by Shell Ventures and Toyota Ventures, with participation from Lowercarbon Capital, Anglo American Platinum, Al Mada Ventures, Blackfinch Ventures, Kibo Invest, Niterra/Global Brain, TOP Ventures, Earth Ventures, and Alumni Ventures. The GTM motion is enterprise field sales with long sales cycles, multi-year pilot demonstrations feeding into commercial offtake, and strategic investor channels providing direct market access into global energy and mobility ecosystems.

Supercritical product offering
Product offeringCore offering
Supercritical develops and sells a high-pressure, ultra-efficient, membraneless electrolyser that produces green hydrogen and oxygen at up to 220 bar without requiring hydrogen compressors. The patented supercritical water electrolysis technology uses a membrane-free, PFAS-free, iridium-free, rare-earth-free cell assembly built from mass-manufactured industrial metals, delivering hydrogen purity up to 99.999mol% and stack efficiency above 90% HHV. First commercial deliveries are targeted for 2027 to industrial customers in ammonia, methanol, refining, distilling, mining, and heavy transport markets.
Product overview
Supercritical offers a single core product: its ultra-efficient, high-pressure membraneless electrolyser technology for green hydrogen production. This electrolyser delivers hydrogen and oxygen at pressures up to 220 bar without hydrogen compressors, using a patented membrane-free, PFAS-free, iridium-free design. The company also showcases three application-focused case studies—WhiskHy (hydrogen direct-fired whisky distillation), GreeNH3 (green ammonia production via Haber-Bosch integration), and Zero Mining (mining sector decarbonisation)—demonstrating how the core electrolyser technology can be applied across different industrial sectors.
