With an estimated investment of 16 billion dollars, the H2 Magallanes project aims to produce 1.9 million tons of green ammonia per year in the Magallanes region.
The French company TotalEnergies, through its subsidiary TEC H2 MAG SpA, has submitted the H2 Magallanes project to Chile’s Environmental Impact Assessment System (SEIA). The initiative involves building a green ammonia production plant in the San Gregorio commune, located in the Magallanes and Chilean Antarctic Region.
The H2 Magallanes project includes the installation of a 5,000 MW wind farm, consisting of 616 wind turbines, which will power seven electrolysis centers with a total capacity of 3.85 GW. These centers will produce green hydrogen from desalinated and demineralized seawater. The hydrogen will then be combined with nitrogen from the air using the Haber-Bosch process to produce up to 10,800 tons of green ammonia daily.
The project’s infrastructure includes a desalination plant with a capacity of 1,300 liters per second, the ammonia production plant, four storage tanks of 60,000 cubic meters each, and a marine terminal for exporting the final product. The plant is expected to have a 25-year lifespan and create up to 10,000 jobs during construction and 1,000 permanent positions during operation.
The project will be developed across 72,000 hectares, with 4,000 designated for key infrastructure. The estimated annual production of green ammonia is 1.9 million tons, which will be exported. The submission of the Environmental Impact Study (EIA) is the culmination of over three years of environmental studies and early public engagement. The environmental assessment process is expected to take two years, with construction scheduled to begin in 2027 and operations slated to start in 2030.
