On the windswept coastline north of Perth, a project of almost unimaginable scale is taking shape. The Murchison Green Hydrogen project, developed by Danish investment fund Copenhagen Infrastructure Partners, represents Australia’s most ambitious attempt yet to convert its abundant renewable resources into exportable clean fuel. The numbers are staggering: up to 6 gigawatts of solar and onshore wind capacity, a 600-megawatt battery energy storage system, and 3 gigawatts of electrolysers working in concert to produce green hydrogen and ammonia for Asian markets. At full capacity, the facility is expected to produce up to 1.9 million tonnes of green ammonia annually, with initial production targeted for 2030.
The Australian Government has accelerated the project’s development through its Investor Front Door program, designed to streamline interactions between government and major project proponents. A first-phase 1.5-gigawatt development received 814 million Australian dollars in production incentives under the Hydrogen Headstart program. These incentives are critical because they bridge the gap between the cost of producing green hydrogen and the price that international buyers are willing to pay.
While Murchison captures headlines with its scale, a smaller project in New South Wales may prove equally significant as a commercial template. Chemical producer Orica has reached a Final Investment Decision on its Hunter Valley Hydrogen Hub, backed by 432 million Australian dollars in government funding. The project will deploy 50 megawatts of electrolyser capacity to produce approximately 4,700 tonnes of renewable hydrogen annually, replacing natural gas feedstock in ammonia production at Orica’s Kooragang Island facility. This is not a demonstration project or a pilot plant—it is a commercial-scale deployment in one of Australia’s most emissions-intensive industrial processes. ARENA CEO Darren Miller described the decision as a critical step that “signals that renewable hydrogen production can be deployed at scale in Australia, shifting the conversation from concept to deployment”.

Australia’s green hydrogen ambitions extend well beyond domestic applications. The country has positioned itself as a future low-cost exporter, with certification schemes for emissions intensity and bilateral mechanisms designed to connect supply with European demand. A proposed auction with Germany worth 400 million euros is set to award contracts by mid-2026, creating a structured pathway for Australian hydrogen to reach European buyers. The economics of green hydrogen remain challenging. When firm delivery requirements are imposed, the delivered levelised cost of hydrogen reaches approximately 8.44 Australian dollars per kilogram in 2030—significantly higher than production-only estimates often cited below 3 dollars per kilogram. This cost gap is precisely what government programs like Hydrogen Headstart are designed to bridge.
The Murchison project alone illustrates the magnitude of what Australia is attempting. The federal government has awarded it major project status, recognising its estimated 15 billion Australian dollar cost and its potential to generate 6 gigawatts of renewable energy at full scale. A consortium including InterContinental Energy, CWP Global, and Murchison Green Hydrogen Pty Ltd is developing the Western Green Energy Hub, a project that covers 15,000 square kilometres and includes 3,000 wind turbines and 25 million solar panel modules, with a planned capacity of up to 70 gigawatts. These are not incremental additions to Australia’s energy system. They represent a fundamental reimagining of the country’s role in global energy trade, transforming it from a fossil fuel exporter to a renewable energy superpower. Whether that vision materialises on the timelines announced will depend on continued policy support, infrastructure investment, and the willingness of international buyers to commit to long-term green hydrogen contracts. The coming years will reveal whether Australia can turn its enormous renewable resource base into a competitive advantage in the global hydrogen economy.
