The Good Earth Green Hydrogen and Ammonia (GEGHA) project near Moree has reached financial close.
Hiringa Energy, alongside Sundown Pastoral Company and the NSW Government, will begin construction in October. The facility will supply low-carbon ammonia and hydrogen to support agriculture and transport.
Solar-Powered Hydrogen and Ammonia Production for Agricultural Use
The facility will sit beside Sundown’s joint-venture Wathagar cotton ginning site, using solar power to generate 4,500 tonnes of low-carbon ammonia and around 224 tonnes of green hydrogen annually. The project partners say the plant will play a key role in reducing emissions in agricultural processes.
Emissions Reduction Through Low-Carbon Fertiliser Deployment
Replacing fossil-fuel-based fertilisers with low-carbon ammonia, the GEGHA project is expected to cut up to 17,000 tonnes of CO₂-equivalent emissions annually—the same as taking 6,500 cars off the road or planting 500,000 trees.
Fertiliser produced will go toward Sundown’s Good Earth Cotton, described as a “positive net-zero, traceable” product. Excess supply will serve neighbouring farms in the Moree Plains, broadening the project’s regional impact.
Hydrogen Integration Across Transport and On-Farm Energy Systems
GEGHA’s hydrogen production supports clean energy transition in other critical sectors.
The green hydrogen output will be deployed in Hiringa’s heavy-vehicle refuelling network, targeting long-haul freight routes. Some of the hydrogen will also be used to displace diesel in on-farm irrigation systems, contributing to decarbonisation “from paddock-to-port.”
Market and Government Support for Practical Hydrogen Deployment
The GEGHA project was described at announcement as a departure from speculative hydrogen concepts.
“This achievement highlights the sustained opportunity for Australia’s green hydrogen industry, proving right-sized, demand-led projects can succeed.” GEGHA is closely tied to the agricultural supply chain and built on a vertically integrated production model. Its structure is intended to serve existing regional demand.
The NSW Government’s support reinforces the move toward scalable, industry-aligned clean energy projects.
