Learn more about the Villeta Project, currently being developed by ATOME Energy, Casale and URBAS Energy-Ingeser. Surplus hydropower form the Itaipu Dam will be used for renewable ammonia production via electrolysis-based hydrogen.
Grieg Star and a series of high-profile maritime consortium partners have assessed the full feasibility for retrofitting a Grieg Star L-Class vessel to run on ammonia fuel. The study concludes that technical & regulatory challenges will not be showstoppers in the transition. A combination of high investment costs, uncertainty over ammonia fuel availability & pricing and slow market development remain the biggest barriers, presenting significant risks for first movers.
In our latest episode of Ammonia Project Features, Asunción Borras (Engie) and Pablo Wallach (Enaex) presented the HyEx project. Although a historical exporter of nitrogen fertilizers, Chile is now a major importer of ammonia, particularly as a feedstock for manufacturing mining explosives. Solar PV generating potential in Chile’s Atacama desert is among the world’s best, and the HyEx project will leverage this to produce renewable ammonia. By 2030, HyEx could produce enough ammonia to completely replace Enaex’s current ammonia imports, with volume left for exports or other applications.
Ammonia co-firing trials will shortly commence in the Philippines, Thailand and Chile, with an initial focus on co-firing rates of 20-30% ammonia. Japanese energy giants JERA and Mitsubishi Heavy Industries continue to be significant players in the co-firing space.
Casa dos Ventos, Comerc and the Transhydrogen Alliance (THA) will continue development of a 2.2 million-tonne-per-year electrolytic ammonia export project at the Port of Pecém in northern Brazil. The country’s renewables-heavy grid will power 2.4 GW of electrolysis capacity, with exports to Rotterdam to start in 2026. THA founding member Proton Ventures recently selected an engineering partner to perform FEED work for the Pecém plant, and was also awarded a construction contract by OCP Group for two world-scale ammonia storage tanks in Morocco.
As part of the HyEx project, Mitsui & Co., Toyo Engineering and Enaex will develop a solar-powered, 18,000 tonnes-per-year renewable ammonia plant in Tocopilla, northern Chile. Just outside of Tocopilla, Sumitomo and Chilean transmission utility Colbún have teamed up to explore renewable ammonia production & export. The pair will also assess million-tonne-per-year production in Chile’s south. Also in South America, Proton Ventures have contracted Fitchner to assess the feasibility of planned renewable production projects.
Meet Engie and Enaex, partners in the HyEx project in Antofagasta (Chile), where Engie will produce renewable hydrogen and Enaex will produce green ammonia to feed subsequent production of mining explosives.
