Provaris plans to produce up to 100,000tpa of green hydrogen from Tiwi H2, which will be exported around the Asia Pacific.


Provaris Energy’s (ASX: PV1) Tiwi H2 green hydrogen and export project has been awarded major project status by the Northern Territory Government.

It has been recognised as having substantial economic and social benefits to the territory and the traditional owners of the Tiwi Islands, and potential strategic significance on a national scale.

The project aligns with the territory’s Renewable Hydrogen Master Plan, which provides a framework for the development of a renewable hydrogen industry focused on enabling activities required to secure private sector investment.

The new status will give Provaris access to whole of government support, including co-ordination and facilitation, assistance in identifying and mapping regulatory approvals, a dedicated project case manager and facilitation of engagement with federal authorities.

As part of the award, Provaris and the Northern Territory Government have entered into a project facilitation agreement (PFA) to achieve timely, efficient and effective development of the Tiwi H2 project and to maximise the economic and community benefits.

Hydrogen production

The Tiwi H2 project will employ solar energy to produce up to 100,000 tonnes per year of green hydrogen and use Provaris’ proprietary GH2 carriers for shipping compressed hydrogen gas to the Asia Pacific region including Singapore, South Korea and Japan.

It is estimated to create 500 jobs during construction and 100 positions once in operation.

First hydrogen is targeted for early 2027 and the project has an estimated 30-year life.

The Tiwi Islands location offers benefits to Provaris’ compressed hydrogen delivery model, including existing port infrastructure at Port Melville; an existing industrial area for hydrogen production; and proximity to key export markets.

Concept design study

A concept design study completed this month has confirmed Tiwi H2 is technically feasible for an integrated compressed hydrogen production and export operation.

The study established a “clear pathway” to advance the project through all work streams including permitting, front end engineering design (FEED), and technical, commercial, economic and financing options.

It also reinforced several outcomes from Provaris’ compressed hydrogen chain scoping study.
