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.
