# 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.

- **Founded:** 2021
- **Headquarters:** Hawthorne, California, United States
- **Founders:** Molly Yang (Co-founder & CEO), Colin Ho (Co-founder)
- **Team size:** ~11 employees
- **Products:** High-efficiency alkaline electrolyzer, Containerized hydrogen system
- **Notable:** Raised roughly $7M total across two seed rounds from Founders Fund, Seven Seven Six, and Fontinalis Partners, Inducted into the 2022 Breakthrough Energy Fellows cohort, Scaled the electrolyzer from a benchtop prototype to an industrial-scale demonstration at its Hawthorne facility

## Products & services

- **High-efficiency alkaline electrolyzer** — An alkaline electrolyzer with a redesigned cell that sheds hydrogen bubbles faster, claimed to deliver roughly 20x higher volumetric power density, cells about 6x thinner and around 9% more efficient than conventional alkaline systems.
- **Containerized hydrogen system** — The electrolyzer packaged into a shipping-container-sized unit that requires only water and electrical inputs, designed for on-site clean hydrogen production for industrial customers.

## Achievements
