Global Brain has invested in Supercritical Solutions Ltd, a company developing innovative, low-cost green hydrogen production technology under high-temperature and high-pressure conditions

Global Brain has invested in Supercritical Solutions Ltd (Supercritical Solutions), a company developing innovative, low-cost green hydrogen* production technology under high-temperature and high-pressure conditions, through its SUISO no MORI Fund (Niterra SUISO no MORI Fund).
Supercritical Solutions is a startup that develops its proprietary high-temperature and high-pressure water electrolysis technology. This core technology enables the production of green hydrogen with world-leading power efficiency of 42 kWh/kgH2. While over 95% of hydrogen currently used in the market is fossil fuel-derived gray hydrogen, there is a growing demand for clean hydrogen in sectors facing decarbonization challenges, such as the chemical industry, industrial heating, and transportation. Green hydrogen is expected to be a primary clean hydrogen source for achieving a carbon-neutral society by 2050; however, cost reduction is essential for its widespread adoption.
Supercritical Solutions manufactures equipment for low-cost production of high-pressure green hydrogen, exceeding 200 bar and with a purity of over 99%, under high-temperature and high-pressure conditions through its unique electrolytic cell design that does not use electrolytic membranes or iridium-based catalysts. The production of high-pressure hydrogen enables significant reductions in compression costs and contributes to improved energy efficiency and cost reduction in industries requiring high-pressure hydrogen.
Global Brain has decided to invest in Supercritical Solutions, recognizing its exceptional technical capabilities, strong management team with high execution skills, and the potential of the clean hydrogen market. Global Brain will contribute to the business growth of Supercritical Solutions with Niterra Co., Ltd.
* Green hydrogen: Hydrogen produced by the electrolysis of water, using renewable electricity
