TotalEnergies subsidiaries have submitted an application for an environmental permit for a $16 billion green hydrogen and ammonia project in southern Chile, according to a regulatory filing on Monday. The initiative, managed by TEC H2 MAG, a Chilean subsidiary, is set to commence operations in 2030.

The logo of French oil and gas company TotalEnergies is seen on a building in Rueil-Malmaison, near Paris, France, April 14, 2025.

The project encompasses a wind farm, seven electrolysis centers for green hydrogen production, a desalination plant, an ammonia plant, and maritime infrastructure for shipping. These components aim to support sustainable energy production and distribution. The ammonia plant will be rolled out in phases, with a capacity to produce up to 10,800 metric tons daily.

Chile has been actively encouraging the development of clean hydrogen projects to advance its renewable energy goals. However, some companies have noted challenges, including extended permitting processes and limited infrastructure, which have slowed progress in this sector.

The project’s website indicates that the environmental permit review is expected to take two years, with construction scheduled to start in 2027. This timeline reflects the thorough regulatory process required to ensure environmental compliance.
