About Ammobia

Ammobia is on a mission to revolutionize the ammonia industry. We are a seed‑stage startup developing Haber Bosch 2.0 – a next‑generation ammonia synthesis process enabling cost‑effective, clean ammonia production. Our proprietary swing reactor system runs at 10x lower pressures and 4x higher conversions than the state of the art, enabling economical production at any plant scale or energy source.

Clean ammonia will support ammonia’s growing role in our decarbonized world, tackling some of the most difficult to abate sectors including chemicals, fertilizers, and heavy‑duty transportation. We are supported and recognized by leading climate tech organizations including Starlight Ventures, the US Department of Energy, Collaborative Fund, Third Derivative, Forbes 30u30, and more.
