Ammobia

Ammobia develops modular ammonia production technology that enables low-cost, low-carbon ammonia manufacturing at any scale through its proprietary Haber-Bosch 2.0 process. The company's advanced reactor technology operates at 30-60 bar pressure (up to 10x lower than conventional) and 400 degrees Celsius (100 degrees lower), achieving 80% conversion per pass compared to 15-30% in traditional Haber-Bosch plants. This results in approximately 50% reduction in plant CapEx and 10-40% lower production costs. Ammobia's modular, feedstock-agnostic plants deploy in standardized units of hundreds of tons per day, compatible across energy sources and optimized for low-carbon production. The technology serves fertilizer, power generation, chemicals, and maritime shipping industries. The company won Shell's New Energy Challenge 2025 and its co-founders were recognized on Forbes 30 Under 30. Founded in 2022 and headquartered in San Francisco, United States, the company has raised approximately $11.7 million at the seed stage, backed by Shell Ventures, Air Liquide, MOL Switch, and Chevron Technology Ventures.
