Topsoe has signed a
contract with Allied, a developer of energy infrastructure projects,
to deliver its dynamic 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 South East Asian markets where
demand for e-fuels continues to grow. Production is planned to start
in Q4 2028/Q1 2029, targeting a capacity of 2,500 MTPD.
Allied estimates that the
project will create up to 2,000 direct construction jobs and 500
direct and indirect jobs for over 25 years. Using Topsoe’s
technology, the CO2 saved
in this project is estimated to be around 1.4 million tons per year,
compared to ammonia produced from conventional (natural gas) routes.
Topsoe is also in discussions with Allied to
supply an undisclosed quantity of its SOEC to produce green
hydrogen. The potential supply and integration of Topsoe’s SOEC
technology for production of green hydrogen—in combination with the
dynamic ammonia technology—will further increase the energy
efficiency of Allied’s ammonia production.
Topsoe’s dynamic ammonia technology, DynAMMO,
adapts the production output of green ammonia in response to
fluctuating supply of renewable electricity. The dynamic green
ammonia loop can handle 3% load fluctuations minute by minute, along
with sustained reliable operation with loads as low as 10% of
capacity.
The dynamic ammonia process plant will enable:
-
the ramping up/down of the ammonia production
bidirectionally at a rate of at least 3% per minute in response to
the fluctuating supply of hydrogen to the ammonia plant;
-
significant reduction in capital expenditure
and operational expenditure since hydrogen storage systems can be
reduced substantially, or otherwise eliminated; and
-
renewable electricity to be stored in a
zero-carbon chemical.
Green ammonia has the ideal characteristics to
enable net-zero because it can function both as a green fuel, an
energy carrier and green fertilizer.
Topsoe’s SOEC electrolysis technology is a
modular design that leverages high-temperature electrolysis. Due to
the nature of the high-temperature electrolysis, Topsoe’s SOEC
technology produces 30% 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.
