  • Revolutionizing agriculture: GEGHA project in NSW harnesses solar power to produce green hydrogen and ammonia, boosting sustainable farming by 2027.

New Zealand's Hiringa Energy and Australia's Sundown Pastoral have secured financial backing for the Good Earth Green Hydrogen and Ammonia (GEGHA) project in New South Wales, with construction set to start in October. The project, financed by National Australia Bank and the NSW Government, will integrate solar power, electrolysis, and ammonia production near Moree. It aims to produce 224 tonnes of green hydrogen annually, converting it into up to 4,500 tonnes of ammonia fertilizer.

The facility will feature a 15-MW electrolyser powered by 36 MW of solar energy, including a 14-MWh battery storage system. The green hydrogen will replace diesel in irrigation and support regional agriculture. GEGHA is expected to be operational by early 2027, marking a significant step in East Coast Australia's green fertiliser supply.

How will the GEGHA project impact green hydrogen and ammonia production in New South Wales?

  • The GEGHA project will significantly boost the production capacity of green hydrogen in New South Wales, contributing to the state's renewable energy targets and reducing reliance on fossil fuels.
  • By integrating solar power and electrolysis, the project will enhance the efficiency and sustainability of hydrogen production, setting a benchmark for future renewable energy projects in the region.
  • The conversion of green hydrogen into ammonia will provide a sustainable alternative to conventional ammonia production methods, which are typically carbon-intensive.
  • The project will support the agricultural sector by providing a green alternative to diesel for irrigation, reducing carbon emissions and promoting sustainable farming practices.
  • The production of green ammonia fertilizer will help reduce the carbon footprint of agriculture in New South Wales, aligning with global efforts to decarbonize the food supply chain.
  • The GEGHA project will create jobs and stimulate economic growth in the region, contributing to the local economy and supporting the transition to a green economy.
  • By demonstrating the viability of large-scale green hydrogen and ammonia production, the project could attract further investment in renewable energy infrastructure in New South Wales and beyond.
  • The integration of battery storage will ensure a stable and reliable supply of renewable energy, enhancing the resilience of the local energy grid and supporting energy security.
  • The project will position New South Wales as a leader in green hydrogen and ammonia production, potentially opening up export opportunities and strengthening international partnerships in the renewable energy sector.
