Project description

The proposed H2TAS project is a large-scale hydrogen and ammonia production facility that would be constructed in the Bell Bay area of northern Tasmania. In November 2021, the project operator, Woodside Energy Ltd, announced that it had secured land for the development in the Austrak Business Park (Long Reach) located east of the Bell Bay Advanced Manufacturing Zone, with Woodside and Austrak having agreed an exclusive option for a long term lease.

The project is planned as a phased development of large-scale production of renewable hydrogen and ammonia.

The project would initially target electrolysis capacity of up to 300 megawatts and production of  200,000 tonnes per annum of ammonia, matched to forecast customer demand.

At full potential, the project could support 1.7 gigawatts of electrolysis capacity for hydrogen and ammonia production, subject to customer demand and utility availability.

The project would use a combination of hydropower and wind power as energy sources.

In May 2021, Woodside Energy announced a project consortium under a Heads of Agreement with Japanese companies Marubeni Corporation and IHI Corporation. Initial feasibility studies have concluded that it is technically and commercially feasible to export ammonia to Japan from the Bell Bay area.

In January 2021, Tas Gas announced it had signed a non-binding agreement with Woodside Energy to begin exploring the possibilities of blending (green) hydrogen into the Tasmanian gas network. The agreement provides the framework to blend up to 10 per cent hydrogen into the network, including hydrogen produced at the proposed H2TAS project

The proponents are targeting a final investment decision in 2023, with construction and commissioning anticipated to take approximately 24 months.
