The group signed a memorandum of understanding (MOU) with Temasek and Keppel Infrastructure Holdings Limited to explore potential shipments from IPL's production sites in Queensland and New South Wales (NSW).
Targeted for markets including Singapore, the green ammonia "may be used as a direct feedstock in green energy generation, or as a hydrogen carrier to provide green hydrogen solutions", IPL said in a news release.
The Melbourne-headquartered company is Australia’s largest supplier of fertilizer on the country's east coast with assets capable of blue/green conversion of ammonia.
Keppel Infrastructure has experience of developing and operating efficient energy and environmental infrastructure, while Temasek is a global investment company.
"IPL will contribute its world class expertise in ammonia production, along with its strategic land at Kooragang Island near Newcastle in NSW," the statement continued.
"The three parties will work closely with state governments to explore the feasibility of essential infrastructure, licences and approvals to facilitate the production and export of green ammonia.
"There is an urgency to develop alternative sources of low carbon fuel options to decarbonise the power, industrial, maritime transportation and the aviation sectors.
"Production of green ammonia can produce carbon-free electricity. It could be a direct fuel, or to reprocessed to produce green hydrogen for use as a fuel feedstock, for example to power gas turbines."
Green ammonia may also be used to replace bunker fuels to decarbonise the global maritime industry, the statement added.
The MOU supports Australia's National Hydrogen Strategy, which has identified seven clean hydrogen hubs across the nation.
IPL managing director and CEO, Jeanne Johns, said: “We are delighted to partner with two of Singapore’s leading companies to investigate new and exciting opportunities to create Australia’s green ammonia industry.
“Both our Kooragang Island site and potential greenfield site in Gladstone have the advantage of being nominated by the Australian Government as locations for hydrogen hub development."
