Project description
(Note: This project is one of six applicants that have been shortlisted by ARENA and invited to submit a full application in the next stage of the AUD$2 billion Hydrogen Headstart Program.)
(Note: In February 2025, Stanwell Corporation in a released statement, noted that the Central Queensland Hydrogen Project (CQ-H2) consortium is considering the State’s announcement that it will not provide further funding to support the CQ-H2 project. Stanwell Corporation also noted that it is also reviewing its involvement in other hydrogen initiatives and will work with relevant stakeholders regarding future steps for these projects.)
Stanwell Corporation (‘Stanwell’) is a Queensland Government owned corporation and a major provider of electricity to Queensland, the National Electricity Market, and large energy customers along the eastern seaboard of Australia. As part of its portfolio renewal strategy, Stanwell has identified renewable hydrogen as a key target market for transforming its business in a lower carbon future.
In May 2020, Stanwell and Iwatani Corporation signed a Memorandum of Understanding to undertake a concept study into a large-scale liquefied renewable hydrogen supply chain between Central Queensland and Japan. The study found that Central Queensland is a globally competitive location for renewable hydrogen production.
In November 2020, a partnership between Stanwell and Iwatani Corporation to progress planning on a new hydrogen export focused facility in Gladstone was announced.
In June 2021, it was announced that Stanwell had signed an Option Agreement with Economic Development Queensland to secure a 236-hectare site at Aldoga, west of Gladstone for its proposed hydrogen production facility.
In September 2021, key project announcements included:
- ARENA announced up to AUD$2.17 million in funding to Stanwell to complete a feasibility study (at a cost of over AUD$10 million) to investigate the technical and commercial viability of a proposed green hydrogen export project to be located at Gladstone, Queensland. Additional funding support for the feasibility study was also provided through the Japanese Ministry of Economy, Trade and Industry (METI).
- Stanwell and Iwatani formed a broader consortium to commence a detailed feasibility study into the proposed project (with consortium membership evolving as the project entered the FEED study stage).
The feasibility study investigated the complete hydrogen supply chain, including electrolysis, storage, handling, liquefaction, transportation, and shipping and was designed with the requirements of an investment decision to move to the front-end engineering and design (FEED) stage.
The feasibility study was completed in June 2022, with bridging activities progressed ahead of FEED studies. The project Feasibility Study was publicly released in December 2022 and offers further details on the technical, commercial and strategic aspects of the development as envisaged at the time of completion of the feasibility study.
In addition to the feasibility study, Stanwell also undertook studies into local workforce and manufacturing development. Work on these programs will continue throughout the bridging and FEED stages of the project.
Following a period of bridging activities, the FEED study stage began in May 2023. In the same month, ARENA announced that it had conditionally approved AUD$20 million in funding to Stanwell to support FEED studies for a large-scale renewable hydrogen project in Gladstone. In June 2022, as part of the State 2022-23 budget, it was announced that AUD$15 million from the Queensland Renewable Energy and Hydrogen Jobs Fund is to be allocated to progress the Central Queensland Hydrogen Project, particularly the planned FEED study.
At the time of commencement of the FEED study stage, the project plans involve a phased development with a commercial operations date of renewable hydrogen targeted for 2029 (initial production targeted at around 200 tonnes of hydrogen per day, installed electrolyser capacity at around 720 MW) ramping up in 200 tonnes per day increments as additional offtakes are secured, with full scale production capacity targeted at around 800 tonnes per day by the early 2030s (rated electrolyser capacity at around 2 gigawatts [GW], and which would require at least 7 GW of associated renewable solar/wind power generation capacity).
Amongst other things, the FEED study stage will examine the development of a hydrogen liquefaction facility at the Port of Gladstone that would produce 400 tonnes per day of liquefied hydrogen for export by the early 2030s.
Up to AUD$69.2 million in funding has been awarded to Stanwell to support the development of a Central Queensland Hydrogen Hub (through the Australian Government’s Regional Hydrogen Hubs Program – Hub Implementation funding stream). The Central Queensland Hydrogen Hub will bring together local, national and international companies and organisations to drive the development of the hydrogen industry in the region. Stanwell, as lead applicant, will work together with the other Central Queensland Hydrogen Hub participants to develop an implementation plan for the proposed concept. See media statement.
In May 2023, Keppel Limited, in announcing it had joined the Central Queensland Hydrogen Project, also announced that it had signed a Memorandum of Understanding with Incitec Pivot Ltd. to further the development of a renewables-based ammonia production facility in Queensland, leveraging the accessibility to hydrogen supply from the Central Queensland Hydrogen Project. Produced ammonia would support the decarbonisation of Incitec Pivot’s domestic manufacturing assets and also exported to Singapore to meet Keppel’s zero or low-emissions power generation needs, with excess production marketed in Asia.
In September 2023, Worley announced that it had been awarded the front-end engineering and design (FEED) work for the Central Queensland Hydrogen (CQ-H2) Project.
In October 2023, Stanwell announced that it had signed a 15-year, 380-MW Power Purchase Agreement (PPA) with ACCIONA Energía to purchase 100 per cent of the output from its planned Aldoga Solar Farm, 20 kilometres north-west of Gladstone. In April 2024, the Queensland Government announced that construction was underway on the Aldoga Solar Farm (on the Central Queensland coast) which would produce electricity to power the proposed Central Queensland Hydrogen Project. The Aldoga Solar Farm will be located adjacent to the proposed hydrogen production facility site for the CQ-H2 Project.
In May 2024, Quinbrook Infrastructure Partners announced that it had commenced the development phase on the proposed Green Iron Project in Gladstone, including potential conversion of magnetite ore (from the Eulogie resource around 70 kilometres west of Gladstone) to green iron using hydrogen produced by the Central Queensland Hydrogen Project.
In September 2024, Australian chemicals manufacturer Incitec Pivot Limited signed a Memorandum of Understanding with the intent to join the CQ-H2 consortium in support of renewable ammonia development.
In September 2024, the CQ-H2 consortium released a fly-through visualisation of the project that showcases the project components and its benefits. The visualisation is available on the CQ-H2 website.
