The facility, planned for NSW’s town of Moree, will provide up to 4,500 tonnes of green ammonia to replace conventionally produced fertilisers.

The project, set to receive AUD $45.2m ($31.7m) in NSW government funding, aims to launch by early 2027. It reached financial close in July 2025.

A joint venture between Hiringa Energy and Sundown Pastoral Company dubbed the Good Earth Green Hydrogen and Ammonia project (GEGHA), it will produce green ammonia through an on-site electrolyser supplying around 225 tonnes of clean hydrogen per year.

Details around the electrolyser and subsequent ammonia synthesis systems remain unclear.

It will primarily supply Sundown’s Keytah cotton farm, with leftover fertiliser earmarked for other local farming operations.

Penny Sharpe, NSW’s Minister for Energy and Environment, praised the plans for helping to decarbonise the state’s hard-to-abate agriculture sector.

Hiringa is also progressing a 5MW green hydrogen project in New Zealand’s South Taranaki also recently reached a final investment decision after a recent final investment decision.

Ammonia’s role as a hydrogen carrier or clean fuel is well recognised, but it is increasingly being recognised as a decarbonisation solution for the agricultural industry.

At COP30 in Brazil, the Hydrogen Council, Unido, Ammonia Energy Association, and International Fertiliser Association launched the Low-Emission Ammonia Fertiliser Initiative (LEAF) to accelerate the use of clean hydrogen-based fertilisers.
