Hysata
Hysata is an Australian clean-energy manufacturer commercialising a capillary-fed electrolyser that splits water into hydrogen at around 95% system efficiency, well above conventional electrolysers. Spun out of the University of Wollongong, the company aims to produce green hydrogen at the lowest cost to help decarbonise hard-to-abate sectors such as steel, chemicals and heavy transport, and is scaling toward gigawatt-scale manufacturing at Port Kembla, New South Wales.
1s1 Energy
1s1 Energy is a materials-science company making green hydrogen cheaper by rethinking the guts of the electrolyzer. Instead of the fluorinated (PFAS) membranes the industry has leaned on for decades, 1s1 builds boron-based proton-exchange membranes and electrochemical components that its partners report can produce a kilogram of hydrogen using roughly 70% of the energy of incumbent devices - already hitting efficiency targets the U.S. Department of Energy set for 2031. Founded in 2019 and run out of Portola Valley, California with labs in Lisbon and Campinas, Brazil, the company sells core components to electrolyzer and fuel-cell makers and runs pilots with utilities and heavy industry.
Hgen
Hgen is a Los Angeles-area climate-tech company building higher-efficiency alkaline electrolyzers that convert water and renewable electricity into clean, low-cost hydrogen for heavy industry. Founded in 2021 by former Tesla and SpaceX engineers, Hgen redesigned the electrolyzer cell to shed hydrogen bubbles faster, claiming roughly 20x higher power density and a much smaller footprint than conventional alkaline systems. The company packages its technology into shipping-container-sized units that need only water and electricity, aiming to undercut the cost of trucked-in liquid hydrogen and help decarbonize chemicals, steel, and other industrial processes.
Vimano
Vimano is a Bengaluru-based deep-tech startup building PFAS-free, ion-selective nanotech membranes for the electrochemical devices that power the energy transition - redox flow batteries, AEM electrolyzers, and hydrogen fuel cells. Its proprietary membrane platform tackles the ion-crossover problem that limits efficiency in long-duration energy storage and green hydrogen, and it also adapts the same polymer-film science to thermal management films for satellites. The company's stated goal is to sit inside 1 out of every 2 large-scale energy storage devices, electrolyzers and fuel cells on the planet.
