Gingerah Energy Hub

The Gingerah Energy Hub brings together over a decade-long deep geological expertise and relationship-building in the Gingerah area.

Theia Energy, partnering with the Karajarri Traditional Lands Association, the representative body corporate of the Karajarri People, is at the forefront of the energy transition by harnessing the natural resources of the Gingerah area with the support and wisdom of the Karajarri People.

This land, situated in the locality of Gingerah hosts abundant natural resources including the earth’s heat, solar irradiation, wind and groundwater. Theia Energy together with the Karajarri People identified the opportunity to build the Gingerah energy hub, a 3GW renewable energy hub to produce 1 million tonne per annum (mtpa) of zero-emission ammonia. Energy will be produced from a mix of renewable energy sources including: solar pv, concentrated solar, wind and geothermal energy. Groundwater will be sustainably sourced and used for electrolysis producing pure hydrogen gas and oxygen from 1.2GW electrolyzers.

Green Ammonia Stage-gated Project Timeline

Land access and location

Situated on Vacant Unallocated Crown Land with access to major ports the Gingerah Energy Hub is ideally located in an area with manageable environmental sensitivities, the support of traditional owners, secure access to the site and proximity to major ports facing the Indian Ocean. Our permits include wind and solar resources (10,000 km²) and geothermal energy resources (3,600 km²) with the potential for future storage of carbon and/or hydrogen in known geological formations.

Traditional owner owned

Theia Energy is working with the traditional owners of the land and the Western Australian Government to perform the site characterisation works required to define the project scope and concept in such a way that environmental impacts are net positive and sustainable.

Green hydrogen

Green hydrogen is produced using electrolysers that separate hydrogen and oxygen from water. Air separation units strip nitrogen from air, which is synthesised with hydrogen from electrolysis using the Haber-Bosch technique to produce green ammonia (NH3).

Green ammonia

Initially, the hub will produce 1 mtpa of green ammonia from up to 3 GW of renewable energy capacity from a mix of renewable energy sources. The capacity needed and footprint will depend on the type of renewable energy used taking sustainability, availability and affordability into consideration.


Harnessing the abundant renewable energy
resources of the Gingerah region including solar, geothermal and wind energy to produce green hydrogen and ammonia.

A combination of generation methods will meet sustainability objectives. The area has a high geothermal gradient allowing energy production from the earth’s heat in combination with solar PV and concentrated solar and potentially wind energy to deliver reliable cost-effective energy with the least environmental disturbance.

Water is sustainably sourced from deep aquifers and treated as needed for electrolysis.
