NEOM green ammonia plant nears 4GW power milestone, targets 1.2 million tonnes by 2027

NEOM Green Hydrogen Company is closing in on a key milestone at the NEOM green ammonia project in Saudi Arabia, with the world’s largest green hydrogen plant on track to complete its 4-gigawatt wind and solar complex by mid-2026, according to the developers.

Located at Oxagon, the $8.4 billion facility is an equal joint venture between ACWA Power, Air Products, and NEOM. Once the renewable power sites are complete, the partners will commission electrolyzers, with the first green ammonia output targeted for 2027. At full run rate, the plant will make up to 600 tonnes per day of carbon-free hydrogen, converted into as much as 1.2 million tonnes of green ammonia a year.

The plant pairs thyssenkrupp electrolyzers with Air Products air separation to feed a renewable-powered Haber-Bosch loop. Air Products holds an exclusive 30-year agreement to offtake all the ammonia produced, shipping it from a dedicated jetty to transport and industrial customers seeking low-carbon fuel.

NEOM says the project will avoid roughly 5 million tonnes of carbon dioxide a year. Green ammonia is drawing interest both as a nitrogen fertilizer feedstock and as a carrier for moving hydrogen over long distances, part of a wider shift as large buyers lock in long-term green ammonia supply.

For fertilizer buyers, the milestone signals how quickly utility-scale renewable ammonia is advancing from the blueprint stage toward commissioning.
