Project description
The Good Earth Green Hydrogen and Ammonia (GEGHA) Project involves the installation of a 27 MW Solar Farm that, when combined with an existing 9 MW solar facility (Stage 1), will provide 36 MW of Behind the Meter renewable energy to the green hydrogen and ammonia plant and Wathagar Ginning facility while retaining Stage 1 existing import and export capacity.
Behind the Meter solar is supplemented with approximately 27 MW of battery storage and a low-capacity import ‘tether’ connection to the grid, for stability and firming. The project proponent advises that Green Certificates will be obtained for grid sourced power.
The production facility consists of 15 MW of electrolyser capacity and a 16 tonne/day green ammonia plant.
Green ammonia in anhydrous form will supply the local and regional farming operations with low carbon fertiliser, displacing existing ‘brown’ anhydrous ammonia or Urea. Sundown Pastoral are a foundation customer.
Around seventy percent (70%) of the hydrogen produced will be used in the manufacture of green ammonia while the remainder would be used to displace existing diesel machinery on farms and as fuel for heavy vehicles, both fuel cell electric vehicles (FCEV’s) and dual fuel systems.
The project will produce around 4,500 tonnes of ammonia per annum, abating approximately 12,000 tonnes of CO2. Total hydrogen production is approximately 4,500 tonnes per year.
In March 2023, the project was awarded AUD$35.8 million of funding through the New South Wales Hydrogen Hubs initiative.
