Project description

The project proponent is progressing development of an off-grid renewables-based hydrogen production facility and a hydrogen derivatives production plant to be located west of Coober Pedy in South Australia.

The hydrogen production facility would use a modular-based production process for the manufacture of hydrogen to mitigate risks.

The project would consist of Integrated upstream, midstream and downstream hydrogen project components:

Upstream – comprises establishment of equipment manufacturing facilities to provide electrolysers and Direct Air Capture (DAC) of water generators required for the project.

Midstream – comprises a renewable hydrogen production component consisting of a series of hydrogen production modules, each comprising:

  • a photovoltaic (PV) solar system.
  • a Direct Air Capture (DAC) of atmospheric water generator.
  • a purpose designed electrolyser.

Downstream – comprises a hydrogen derivatives production facility which could include production of e-methane and ammonia.

The project would provide its own renewable electricity supply and utilise water produced from DAC of water. The PV system would provide power to the electrolyser, ancillary services, and DAC of water.

Project design incorporates buffer storage at site for hydrogen and hydrogen derivates. Rail is currently the preferred means of transport of the hydrogen derivatives to Port Bonython facility. Negotiations are progressing to secure required nitrogen and carbon dioxide necessary for the production of hydrogen derivatives.

At full capacity, the project would be designed to produce approximately 500,000 tonnes of hydrogen per annum. On completion, the project would comprise a 10 GW midstream network (made up of 5 MW modules) with power from the PV system supporting, amongst other things, the electrolyser system (electrolysers, balance of plant, etc) and direct air capture of water and CO2.

The project proponent has advised of the following status of activities (as of August 2025):

  • Lead finance advisor and project finance bank has been appointed and is in process of raising funding commitments ahead of FID.
  • A Joint development Partner has been selected to co-develop the hydrogen production module.
  • Equity joint venture partners for the equipment manufacturing facilities have been secured.
  • Discussions have been underway with a short list of Engineering, Procurement and Construction (EPC) contractors, with a preferred candidate selected.
  • Completed the first stage of the FEED with second stage FEED underway and scheduled for completion by the third quarter of 2025.
  • Advanced negotiations with the land holder and agreements were signed, finalisation of agreements will take place at FID.
  • Identified sites for the manufacturing facilities and discussions are progressing to acquire the land.
  • Offtake discussions are at the advanced Term Sheet stage.
