Project description

The project proponent is progressing development of a 10 GW (off grid) renewables-based hydrogen production facility with both a feasibility study and the first stage of FEED studies completed. The modularised approach to project development has been approved at corporate level and discussions for offtake are at a term sheet stage.

The project includes two equipment manufacturing facilities, for supply to the project and sale to domestic and international markets, and hydrogen derivatives production facilities using the produced hydrogen to produce hydrogen derivatives.

The project proponent has indicated that discussions are well advanced with an EPC company to construct the project and with co-investors to joint venture in the hydrogen derivatives production facility.

The hydrogen production facility will 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 of (a) a 1 GW per annum electrolyser manufacturing facility, and (b) a water production unit manufacturing facility.

Midstream – comprises a renewable hydrogen production component (reaching 10 GW scale at full capacity) consisting of a series of hydrogen production modules, each comprising:

  • a photovoltaic (PV) solar system;
  • a concentrated parabolic trough solar thermal heater;
  • a water manufacturing unit (WMU); and
  • a purpose designed electrolyser; and

Downstream – comprises a chemical production facility which could include:

  • e-methanol;
  • e-kerosine; and/or
  • fuel ammonia.

At full capacity, the project would be designed to produce over 1,000 tonnes of hydrogen per day from a 10 GW electrolyser plant capacity.

The project would provide its own renewable water produced from dewatering air, off grid renewable electricity supply and carbon capture. The PV system would provide power to the electrolyser, ancillary services, and direct air capture of CO2.  The solar thermal heater would provide power to the project and process heat to the WMU (which produces H2O). Carbon dioxide would be used in the chemical facility to produce renewable fuels for use by industries in hard to abate sectors.

The project proponent has indicated it has:

  • established the founding consortium to undertake the development of the hydrogen production facility and is bringing new members to the consortium to co- invest and develop the upstream and downstream components of the project;
  • completed the first stage of the FEED and is now optimising the design;
  • commenced discussion with lead project finance banks;
  • advanced negotiations with the land holder and agreements are expected to be signed by mid-2023;
  • identified sites for the manufacturing facilities and is progressing discussions to acquire the land;
  •  begun discussions with a major Asian based utility for purchase of the full volume of the project’s output;
  • targeted the latter part of 2024 for commencement of construction; and
  • commenced an assessment to expand the project given the demand for offtake.

The project would be located in the Western Davenport region of the Northern Territory. The region covers almost 24,500 square kilometres and is located approximately 150 kilometres south of Tennant Creek.

The project proponent has indicated that the first stage of FEED studies has been finalised and design optimisation is underway.

Project design incorporates buffer storage at site for hydrogen and hydrogen derivates. Rail is the preferred means of transport of the hydrogen derivatives to Darwin’s Middle Arm port facility. A combination of bio-carbon and direct air capture is being progressed to provide the carbon dioxide necessary for the production of hydrogen derivatives.
