Tokyo pilots green hydrogen-to-fertilizer link
Written by Natalie Noor-Drugan
Japan’s Tsubame BHB has been picked by the Tokyo Metropolitan Government (TMG) for a one‑year pilot to turn Tokyo‑produced green hydrogen into nitrogen fertilizers. The “Nitrogen-based Fertilizer Production Project Using Tokyo-Produced Green Hydrogen” will run from 1 April 2026 to 31 March 2027.
Green hydrogen from a new TMG facility in Keihinjima, Ota Ward, will be supplied to Tsubame BHB’s pilot ammonia plant once the hub starts up in October 2025. The ammonia will be used with partner companies to make trial batches of nitrogen fertilizer, directly connecting an urban hydrogen hub with fertilizer‑grade ammonia output. TMG has identified green hydrogen from renewables as a key tool for cutting emissions from conventional “grey” hydrogen‑based ammonia production.
