Globally, operational renewable ammonia projects have exceeded one gigawatt (GW) of installed electrolyser capacity for the first time. Kevin Rouwenhorst of the Ammonia Energy Association (AEA) provides an overview of well-advanced projects and the associated technology options for ammonia synthesis.
Ammonia is poised to grow beyond fertilizers into energy transition roles, with lowcarbon pathways via blue ammonia and green ammonia, supported by existing logistics and market structures. To support this transition, Stamicarbon is expanding its NX STAMI™ ammonia technologies – with a mediumpressure design for large, CCUSintegrated plants and a highpressure design for small/ medium renewable projects – demonstrating efficiency, reliability, and cost advantages.
ATOME has signed a definitive offtake agreement with Yara International for its Villeta project in Paraguay.
Could demand mandates help the build the market for green fertilizers – by placing mandatory purchasing requirements on large-scale end users?
ATOME says that it has signed a definitive offtake agreement with Yara for the purchase of the entire 260,000 t/a output of the low-carbon Villeta project. The plant will be based on 100% renewable baseload power, and will displace some 500,000 t/a of carbon dioxide equivalent. ATOME says that the agreement represents the last commercial milestone in its path to a final investment decision (FID), following the successful completion of other key commercial items, including the signing of the $465 million fixed-price, lump-sum engineering, procurement and construction contract with Casale.

Kent, a global leader in integrated energy services, has been appointed by ACWA Power as owner’s engineer for the Yanbu Green Hydrogen Hub, a major green hydrogen and ammonia export facility being developed in Saudi Arabia. Situated in the port city of Yanbu on the Red Sea, the project will feature full integration across the green hydrogen value chain. This includes its own dedicated renewable power generation, desalination plants, ammonia production lines and an export terminal. At full scale, the facility will deliver up to 400,000 t/a of renewable hydrogen, converted into over 2.2 million t/a of green ammonia for international markets. With more than 4 GW of electrolysis capacity planned, the Yanbu hub is expected to be nearly twice the size of the NEOM Green Hydrogen Project.
ATOME says that the European Investment Bank (EIB), the lending arm of the European Union, has approved financing in-principle of up to $135 million for the company’s flagship Villeta Project. EIB is one of ATOME’s senior debt providers for Villeta and the announcement follows the Green Climate Fund approval earlier this month. Details of the financing will be finalised in early course, following closing of the debt package with the consortium of leading international development finance institutions. Based on the progress with financing, ATOME is projecting a final investment decision by the end of September 2025.
Jilin Electric Power says that it has commissioned one of the world’s largest green hydrogen and ammonia plants in Jilin Province. Jilin says that this is the world’s largest operating green ammonia plant, with a capacity of up to 32,000 t/a of green hydrogen and 180,000 t/a of green ammonia; the largest combined PEM and alkaline electrolyser system, combining 196 MW of alkaline electrolysis and 52 MW of PEM electrolysis, respectively; and the world’s largest block of solid-state hydrogen storage - 48,000 Nm3. The plant is fed by 800 MW of installed renewable power. The green ammonia is EU-certified under low-carbon fuel standards, and offtake agreements are in place with companies located in Europe, Japan and South Korea.
Saudi power group ACWA Power has awarded a front-end engineering design (FEED) contract to a consortium of Spanish engineering firm Tecnicas Reunidas and Sinopec Guangzhou Engineering for the development of a large green hydrogen and ammonia project in Yanbu. The project would include 4 GW of electrolysis capacity, enabling the production of 400,000 t/a of green hydrogen, which will then be converted into green ammonia for export. The plant’s scope also includes water desalination infrastructure and an export terminal to support global distribution, though renewable generation assets are excluded from the current design phase.
