Project description

(This project was previously titled the Tiwi Green Hydrogen Export Project.)

Provaris (previously Global Energy Ventures: GEV) has announced plans to develop a green hydrogen export project located on the Tiwi Islands, Northern Territory, with a phased capacity up to 2.8 Gigawatts (GW) of solar generating capacity, producing up to 100,000 tonnes per annum of green hydrogen.

The Tiwi Islands are located along the northern most part of Australia, with access to existing port infrastructure and the industrial precinct at Port Melville and export markets in the Asia-Pacific region.

The project proponent is evaluating a staged approach to construction, which would move in parallel with the development and full class approval program for its compressed hydrogen carrier:

  • Subject to market demand, an initial development phase of approximately 0.5 GW of installed solar generation (consistent with 15,000 tonnes per annum of hydrogen production), commencing with a fleet of H2 Neo (430 tonne) compressed hydrogen carriers.
  • Expanding to 2.8 GW of installed solar capacity (consistent with 100,000 tonnes per annum of hydrogen production) as the regional hydrogen market grows and supply chain efficiencies improve. Larger capacity 2,000 tonne carriers may be introduced as required to match future supply and demand locations.

Water requirements (feed water and cooling) for the electrolyser facility will be from desalination of sea water sourced from the Apsley Strait.

Financial close for the initial phase of the project is targeted for late 2023, with first hydrogen export to commence in late 2026, subject to all commercial and regulatory approvals and customer offtake.

The proponent has indicated a 2022/23 development program for the project, with an initial focus on environmental permitting:

  • Darwin based EcOz Environmental Services (EcOz) has been engaged to prepare the environmental Referral submission for lodgement with the NT Environment Protection Authority (NT EPA), with lodgement expected in the June quarter 2022.
  • Consultants have also been engaged to prepare engineering desktop studies supporting the Referral submission, covering the key areas of solar generation, power transmission and water desalination.
  • The project proponent has identified and is engaging with key stakeholders, including with the Munupi Landowners, Tiwi Land Council, Tiwi Plantation Corporation, Northern Territory Port and Marine, Office of Township Leasing and Northern Territory Government, and is also progressing product offtake activities.
