A joint venture between TotalEnergies and Eren Groupe has proposed a large-scale 2.7 GW solar-plus-storage project in Australia’s Northern Territory, marking a significant step toward building a green hydrogen ecosystem in the region.
The project, part of the broader Darwin-based hydrogen initiative, will combine utility-scale solar photovoltaic generation with an estimated 6 GWh battery energy storage system. Developed under the TE H2 platform, the facility is expected to supply renewable power to a planned hydrogen production hub, supporting the region’s ambitions to become a major exporter of green hydrogen. The proposal has been submitted for environmental approval under Australia’s EPBC framework, indicating an early stage of development.
If approved, construction could begin later this decade, with timelines dependent on regulatory clearances and final investment decisions. Located near Darwin, the project is designed to deliver firm, dispatchable renewable energy by integrating battery storage, addressing intermittency challenges associated with solar generation. The scale of the development positions it among the largest hybrid renewable energy projects globally.
Industry observers note that such integrated solar-plus-storage and hydrogen-linked projects are gaining traction in Australia, driven by strong resource potential and growing international demand for low-carbon fuels. The initiative underscores increasing collaboration between global energy players to accelerate large-scale clean energy transitions.
