Fukushima, Japan now has a fully operational renewable ammonia plant producing up to 4 tons per day. Japan-based JGC Holdings Corporation provided engineering and construction services, while US-based KBR licensed the green ammonia production technology and provided proprietary equipment. Denitrification (DeNO_X) of power plants is the designated offtake sector for the ammonia produced.

The JGC owned-and-operated plant:

• features alkaline electrolysers (supplied by Asahi Kasei) for low-carbon hydrogen production
• sources electricity from an adjacent photovoltaic plant to provide electricity (with back up power available from grid)
• featues an integrated control system (developed by JGC and Asahi Kasei) to manage hydrogen production in response to variation in power supply
• features KBR’s K-GreeN Advanced Process Control
• receives deliveries of liquified nitrogen via tanker trucks
• was sponsored by New Energy and Industrial Technology Development Organization (NEDO), a national research and development agency in Japan

Delivering one of the world’s first green ammonia plants shows what’s possible when industry leaders unite behind innovation. By combining KBR’s proven ammonia synthesis technology with advanced electrolyzers, nitrogen generation, and smart energy storage, we’re demonstrating that reliable, renewable based ammonia is not just the future, it’s here today.

The project was announced and the trajectory described by the JGC team at the AEA Global and AEA APAC 2022 Conferences. Earlier in 2026, the plant was successfully commissioned including the 10MW alkaline electrolysis facility.
