TotalEnergies and Eren Groupe JV plans 2.7GW solar-plus-6GWh storage project for Northern Territory green hydrogen hub

Type: Development · Technology: Hybrid · Country: Australia · Capacity: 2.7 GW · Announced: 2026-03-17

A joint venture between TotalEnergies and Eren Groupe, operating as TE H2 and Darwin H2 Project Nominee, has submitted plans for the Wak Wak Solar Farm, a 2.7GW solar PV and 6GWh battery energy storage system (BESS) project in Australia's Northern Territory. This project, located 48km southeast of Darwin, is the first phase of a planned solar-powered green hydrogen production and export operation. The facility will generate renewable energy for the Greater Darwin Region's existing industry and power a green hydrogen production facility at the Middle Arm Precinct, aiming to produce over 80,000 tonnes of hydrogen annually. The project area spans up to 3,400 hectares, with a disturbance footprint of 2,500 hectares, and includes 900 hectares of wildlife corridors. An overhead transmission line, approximately 30km long, is also planned to connect the facility to the Middle Arm Precinct within an existing Northern Territory government utilities corridor.

Analysis

TotalEnergies and Eren Groupe, through their TE H2 joint venture and Darwin H2 Project Nominee, have submitted plans for a massive 2.7 GW solar PV and 6 GWh battery energy storage system in Australia's Northern Territory. This Wak Wak Solar Farm, announced on 2026-03-17, represents the foundational first phase for a planned green hydrogen production and export operation. Located 48km southeast of Darwin, the hybrid facility will generate renewable energy for the Greater Darwin Region's existing industry while primarily powering a green hydrogen production facility at the Middle Arm Precinct. The project aims to produce over 80,000 tonnes of hydrogen annually, establishing a significant industrial anchor for the region. A 30km overhead transmission line will connect the generation site to the Middle Arm Precinct within an existing Northern Territory government utilities corridor, streamlining infrastructure development. The project area spans up to 3,400 hectares, with 900 hectares dedicated to wildlife corridors, indicating a considered approach to land use. This Australian development significantly expands TE H2's global green hydrogen portfolio, adding to its 500 MW project in Tunisia and a 2 GW project in Mauritania. As a joint venture between TotalEnergies and Eren Groupe, TE H2 demonstrates a clear, aggressive strategy to develop large-scale green hydrogen projects worldwide. TotalEnergies, a global integrated energy company, further diversifies its energy production and marketing capabilities with this substantial renewable energy and hydrogen initiative in Australia, aligning with its stated goal of providing more sustainable energy. The project's ambition to produce over 80,000 tonnes of green hydrogen annually positions the Northern Territory as a key player in the emerging global green hydrogen export market. The hybrid solar and storage design provides the consistent power required for large-scale electrolysis, a critical factor for reliable green hydrogen production.
