Hiringa Energy and Sundown Pastoral Company have commenced construction of the Good Earth Green Hydrogen and Ammonia (GEGHA) project in New South Wales, marking a significant advancement in Australia’s renewable hydrogen and low-carbon agriculture sectors.
Located near Moree in New South Wales, the project will feature a 15 MW solar-powered electrolysis facility integrated with green ammonia production infrastructure. Once operational, the facility is expected to become the state’s first fully integrated green hydrogen and ammonia production hub designed specifically to support agricultural decarbonization.
The project represents a growing industry trend toward combining renewable energy generation with localized hydrogen and ammonia production to reduce emissions from agriculture, one of the most carbon-intensive sectors due to its reliance on diesel-powered equipment and fossil fuel-based fertilizers.
Backed by an estimated investment of AUD 70 million, the project has secured approximately AUD 45.2 million in funding support from the New South Wales government, highlighting increasing policy support for renewable hydrogen infrastructure and regional clean energy development.
According to project developers, the facility is expected to produce more than 200 tonnes of green hydrogen annually along with up to 4,500 tonnes of green ammonia fertilizer per year. The output will primarily support operations at Sundown Pastoral’s Keytah cotton farm, reducing dependence on conventional diesel fuel and carbon-intensive fertilizer imports.
Industry analysts view the project as strategically important because it demonstrates the commercial integration of renewable energy, hydrogen production, and sustainable fertilizer manufacturing within a regional agricultural ecosystem. Surplus hydrogen and ammonia production is also expected to be supplied to nearby agricultural users, creating a localized low-carbon energy and fertilizer supply chain.
Electricity for the electrolysis process will be sourced from the adjacent Wathagar solar farm, which is currently undergoing expansion. The integration of dedicated renewable generation with hydrogen production infrastructure is increasingly being viewed as a critical model for improving long-term economics and emissions performance within emerging hydrogen markets.
From a market perspective, the project supports Australia’s broader ambition to position itself as a global leader in renewable hydrogen production and low-carbon industrial commodities. The development also reflects growing momentum behind decentralized hydrogen hubs capable of supporting industrial, transport, and agricultural decarbonization simultaneously.
Experts note that green ammonia projects such as GEGHA could play a significant role in reducing exposure to volatile global fertilizer and fuel markets while strengthening regional energy security and supply chain resilience.
The New South Wales government has described the project as a scalable and replicable model for regional clean energy deployment, particularly in agricultural economies seeking to reduce carbon intensity without compromising productivity.
The GEGHA project received regulatory approval in March 2026, with commercial operations expected to begin in 2027.
