Topsoe signs first Australian green ammonia tech contract

Topsoe signs first Australian green ammonia tech contract
Putting Australia on the renewable fuels map, Allied Green Ammonia is developing a green ammonia plant project in the Northern Territory (photo courtesy Allied Green Ammonia).

Denmark-headed Topsoe A/S, a global leader in carbon emission reduction technologies, has announced that it has signed a contract with Allied Green Ammonia Pty Ltd, an Australian developer of energy infrastructure projects, for the delivery of its green ammonia technology for Allied’s project in Gove, Northern Territory, Australia.

The produced green ammonia is intended to be exported from Gove to the expanding Southeast Asian markets where demand for electro-fuels (eFuels) continues to grow.

Production is planned to start in Q4 2028/Q1 2029, targeting a capacity of 2,500 tonnes per day.

Allied Green Ammonia estimates that the project will create up to 2,000 direct construction jobs and 500 direct and indirect jobs for over 25 years.

We are confident that the geographical location and existing infrastructure in Gove in combination with the most energy-efficient hydrogen and green ammonia technology will lead to the lowest levelized cost of green ammonia production in Australia. We are delighted to receive strong endorsement from the local Gumatj Corporation and the Northern Territory government, both of whom eagerly support the development of our green ammonia project in Gove, said Alfred Benedict, Founder and Managing Director of Allied Green Ammonia.

“DynAMMO” process

According to Topsoe, its “DynAMMO” dynamic ammonia process plant will enable the ramping up/down of the ammonia production bidirectionally at a rate of at least 3 percent per minute in response to the fluctuating supply of hydrogen to the ammonia plant.

This translates into a significant reduction in capital expenditure and operational expenditure since hydrogen storage systems can be reduced substantially, or otherwise eliminated.

Using Topsoe’s technology, the carbon dioxide (CO2) avoided in this project is estimated to be around 1.4 million tonnes per year, compared to ammonia produced from conventional (natural gas) routes.

We are excited to embark on this journey with Allied and to support the growing demand for eFuels production in Australia. Allied’s project is completely in line with our ambition to deliver carbon reduction technologies for reaching net zero. Our dynamic green ammonia solution supports this by enabling the production of e-fuels for energy-intensive industries and long-distance transportation, said Kim Hedegaard, CEO of Power-to-X at Topsoe.

Possible delivery of SOECs

Topsoe is also in discussions with Allied to supply an undisclosed quantity of its Solid Oxide Electrolysis Cell (SOEC) to produce green hydrogen.

According to Topsoe, the potential supply and integration of Topsoe’s  (SOEC) technology for the production of green hydrogen – in combination with the dynamic ammonia technology – will further increase the energy efficiency of Allied’s ammonia production.

The SOEC electrolysis technology is a modular design that leverages high-temperature electrolysis – a tested and proven process that enables industrial-scale production of green hydrogen using renewable electricity.

Due to the nature of the high-temperature electrolysis, Topsoe’s SOEC technology produces 30 percent more hydrogen per total power input when compared to conventional electrolyzer technologies.

Additionally, when coupled with waste heat-producing technologies (such as those used in ammonia, methanol, or steel production), SOEC allows for the lowest levelized hydrogen cost with the highest level of energy efficiency per megawatt volume, no matter the industry.
