Ammobia Raises $7.5 Million to Pilot Lower-Pressure Ammonia Production

The funding backs a 10‑ton‑per‑day pilot to validate a patent‑pending reactor touted to cut costs, enabling flexible operation with renewable hydrogen.

Large scale ammonia production facilities to make fertilizers may soon be a thing of the past with reinvention of the century old technique.

Overview

  • The company says its process runs about 150°C cooler and at roughly 10× lower pressure than conventional Haber‑Bosch.
  • Seed investors include Shell Ventures, Air Liquide’s ALIAD, Chevron Technology Ventures, Chiyoda Corporation, and MOL Switch, according to company disclosures.
  • Ammobia reports operating a small unit for about a year and plans modular commercial units targeting roughly 250 tons per day following the pilot.
  • A patent filing describes using a sorbent inside the reactor to remove ammonia as it forms, which the company cites to enable the lower operating conditions.
  • The firm claims up to 40% lower production costs, with press materials citing up to half for the synthesis loop, though the approach remains unproven at commercial scale.
