Allied Green Ammonia’s hydrogen-to-ammonia project in Australia moves forward

SPG Steiner, a German-based EPCM contractor for the energy, petrochemical and chemical industries, has signed an agreement with Allied Green Ammonia (AGA), an Australian-based company, for the supply of two large-scale 40,000-tonne cryogenic full containment double-wall ammonia storage tanks and an associated refrigeration system.

These tanks will store 950,000 tonnes per year of green ammonia produced by AGA and shipped to its offtake partner.

Philippe Steiner of SPG Steiner claimed: “Our extensive track record, state-of-the-art design, advanced welding techniques, and comprehensive knowledge of ammonia’s stress corrosion cracking ensure the highest safety and quality. Our partnership with AGA extends our commitment to clean energy solutions worldwide, now including Australia.”

Alfred Benedict, Founder & Managing Director of AGA, commented: “This agreement with SPG Steiner builds on our progress and strategically positions AGA as we advance towards FEED and FID. Partnering with global leaders like SPG Steiner validates our plans for world-leading clean energy initiatives and strengthens our list of highly credentialed partners.”

To note, in the Gove Peninsula, Northern Territory, Australia, AGA is developing a green ammonia production facility that will produce green hydrogen as a source of ammonia based on renewable energy, aiming to reduce 1.8 million tonnes of carbon emissions annually from the global ammonia industry.

In 2024, AGA signed a basic engineering and design package (BEDP) with U.S. Plug Power for a 3-gigawatt (GW) electrolyzer plant supplying hydrogen to the planned ammonia facility.

According to Plug Power, the facility taps into “abundant renewable energy resources and strong energy infrastructure,” and the proposed location of Gove Peninsula strategically aligns with Asia’s trading partnerships.
