New Zealand-based Hiringa Energy and Australian group Sundown Pastoral will develop the Good Earth Green Hydrogen and Ammonia Project (GEGHA), which will produce ammonia-based fertiliser & hydrogen for fuel cells to support cotton farming near Moree, New South Wales. The partners are already looking to expand to multiple production projects in the area.

In recent weeks, governments in Australia and New Zealand have announced major financial awards to accelerate development of local green ammonia plants. In Australia, ARENA awarded AU $995,000 (US $0.6 million) to Yara and ENGIE for their solar ammonia pilot at Yara Pilbara. In New Zealand, the Provincial Growth Fund gave NZ $19.9 million (US $11.3 million) to Ballance-Agri Nutrients and Hiringa Energy for their wind-fed ammonia plant at Kapuni. Both projects will demonstrate that an existing fossil ammonia plant can be decarbonized in increments. Renewable hydrogen can be introduced in small amounts, displacing only a fraction of the plant's natural gas consumption but demonstrating and de-risking the technologies. Then, the renewable energy farms and electrolyzers can be scaled-up in stages, eventually replacing all the natural gas requirements and completing the conversion of a fossil asset to a renewable asset.

Green ammonia plants are being announced quicker than I can report. Here is a summary of four new projects that propose to use electrolyzers, fed by renewable power, to produce hydrogen for ammonia production. These are big companies, operating in regions with excellent renewable resources, making significant investments in their future. In Chile, it is Enaex, a major ammonium nitrate manufacturer, supplying explosives to the mining industry. In Australia, it is Incitec Pivot, "the second largest supplier of explosives products and services in the world," and Wesfarmers, "the largest Australian company by revenue," according to Wikipedia. In New Zealand, it is Ballance-Agri Nutrients, a big farmers' co-operative and the country's sole fertilizer producer. Each aims to make its business "future-proof." The transition from fossil ammonia to renewable ammonia is underway.
