AustriaEnergy International has submitted the first phase of a US$11bn green hydrogen/green ammonia project to the Chilean environmental authority. The first phase of is composed of a seawater desalination plant and an onshore wind project consisting of 194 turbines with a combined capacity of 1.4 GW. The project aims to install an electrolyser to produce 270 kt/year of green hydrogen and 1.3 Mt/year of green ammonia and a multi-purpose port with a sea terminal. The environmental approval is expected by the fourth quarter of 2025, with construction works planned to begin in the first half of 2027 to start commercial operations by the second half of 2030. The second phase of the project includes an additional 2.1 GW wind plant, and it is planned to be submitted for approval during the first quarter of 2026, with a 6-year construction period. Both phases are expected to have a 50-year operating period.
The project is a joint venture between AustriaEnergy (24.5%), ÖKO Wind (24.5%) and Copenhagen Infrastructure Partners (CIP, 51%), with CIP expecting to obtain all of joint venture shares in 2026 when the final investment decision (FID) is made.
Chile’s National Green Hydrogen Strategy (2020) targets to install 5 GW of electrolysis capacity (200 kt/year of H2) operating and under development by 2025 (28 GW and 2.7 Mt/year of H2 by 2030), producing the most cost-efficient green hydrogen and becoming a major exporter by 2030.
