TotalEnergies, through its Chilean subsidiary TEC H2 MAG, has initiated the environmental permit process for a monumental $16 billion green hydrogen and ammonia project in southern Chile. The project, slated to begin operations by 2030, represents one of the most ambitious clean energy developments in the region. It will feature a large-scale wind farm, seven electrolysis facilities to produce green hydrogen, a desalination plant to provide necessary water resources, an ammonia plant, and specialized maritime infrastructure to support global shipping and distribution.
Chile has positioned itself as a leader in green hydrogen development, driven by its vast renewable energy resources, particularly in the southern and northern regions. However, the country’s early advantage in this sector has recently been challenged by concerns over bureaucratic delays and insufficient infrastructure, which have slowed the progress of various projects. Industry leaders have emphasized the need for streamlined permitting and faster regulatory processes to maintain competitiveness in the global race for clean energy leadership.
The environmental review for the TotalEnergies-backed project is expected to take approximately two years, with construction anticipated to begin in 2027. Once operational, the ammonia plant within the complex will produce up to 10,800 metric tons per day, making it one of the largest facilities of its kind globally. Production will be phased in over time, allowing for a gradual scaling of operations and increased efficiency. The use of green hydrogen, derived from renewable-powered electrolysis, allows for the creation of ammonia with minimal carbon emissions, supporting decarbonization goals in multiple sectors including energy, agriculture, and transport.
This strategic move aligns with Chile’s long-term energy transition objectives, which prioritize low-carbon industrial growth and the expansion of sustainable exports. The country’s geographic and climatic conditions provide ideal settings for wind and solar power generation, making it a promising hub for renewable hydrogen production. If successful, the TotalEnergies initiative could serve as a model for similar projects around the world, while also positioning Chile as a key supplier in the future global green hydrogen market. The integration of complex infrastructure across the energy and maritime sectors underscores the scale of investment and planning involved, marking a significant milestone in the global shift toward cleaner energy solutions.
