Topsoe and green ammonia early-mover First Ammonia, announced that they have entered into a capacity reservation agreement to kickstart the global market for green ammonia.

Topsoe’s solid oxide electrolyzer cells (SOEC) will be installed in First Ammonia’s green ammonia plants around the world in the coming years. The agreement provides for an initial purchase of 500 MW of SOEC units and is expandable to up to 5 GW over the lifetime of the agreement. Topsoe’s SOEC manufacturing plant is to be built in Herning, Denmark, and has recently received FID from the board.

At 5 GW, this would be the largest ever electrolyzer reservation of any type. The production of 5 MM metric tpy of green ammonia produced would eliminate 13 MMtpy of CO₂ emissions, the equivalent of taking 9-MM petrol-fueled cars off the road.

First Ammonia has been developing sites around the globe with the first installation of 500 MW of capacity to be installed at locations in Northern Germany and Southwestern U.S. These projects will be the world’s first commercial-scale, green ammonia production facilities with operation planned for 2025. First Ammonia will operate all its plants dynamically to support existing renewable power markets.

Joel Moser, CEO of First Ammonia said, “We have the utmost confidence in Topsoe and its storied scientists and engineers, which is why we have chosen Topsoe as our partner. With their cutting edge SOEC electrolyzers and industry leading ammonia synthesis, we will develop facilities around the world to produce millions of tons of green ammonia from water and air. Ammonia saved humanity from starvation a century ago as a replacement for depleted sources of fertilizers, in large part due to Topsoe’s excellence. Ammonia can save humanity once again as the workhorse of the hydrogen economy, replacing petrochemicals to decarbonize agriculture, transportation and power storage and generation.”

Roeland Baan, CEO of Topsoe said, “We need to accelerate the development and industrialization of sustainable solutions, while also increasing energy independence, which is why we are delighted to partner with First Ammonia on the global development of its green ammonia facilities. With this agreement, we enable the production of millions of tons of green ammonia in support of the decarbonization agenda.”

Green ammonia to replace hydrocarbon-based fuels for a wide range of use cases

Green ammonia has the highest volumetric energy density out of all the H₂-based energy sources – much more than pure H₂ – which makes it cheap and easy to store and transport. With an existing global ammonia infrastructure, green ammonia can quickly and easily replace hydrocarbon-based fuels for a wide range of use cases, with ammonia fueled ships already on order and ammonia power stations under development.

By operating dynamically—producing ammonia during off-peak power demand hours—First Ammonia will be a net contributor to the economics of renewable power production, providing for the further build-out of additional renewable power wherever they build a production plant.
