Project description

Provaris 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, two phases of development are proposed with installed solar generation and hydrogen generation commencing with a fleet of H2 Neo 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 H2Max carriers may be introduced as required to match future supply and longer-distance demand locations.

On 30 June 2022, Provaris announced the lodgement of a Referral Submission to the Northern Territory Environment Protection Authority for its proposed 2.8 GW Tiwi H2 Project. The announcement includes summary details on the project proposal footprint and layout, as well as the various studies included in the submission. The announcement noted that project next steps included referral consultation with key stakeholders, continuation of engineering surveys and monitoring, request for proposal and appointments of lead consultants, preparation for and commencement of solar monitoring, and partner discussions regarding offtake, investment, development and future ownership structure of the project.

In October 2022, Provaris announced the lodgement of a EPBC Referral to the Federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) addressing any potential impacts to matters of national environmental significance.

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/early 2024, with first hydrogen export targeted to commence in early 2027, subject to all commercial and regulatory approvals and customer offtake.

In August 2022, the Northern Territory Government announced the project had gained Major Project Status.
