Orsted, Yara International link up in green ammonia development effort

Bloomberg:

Orsted A/S, the world’s biggest developer of offshore wind farms, plans to use its latest Dutch installation to make green ammonia for use in fertilizer.

The Danish utility will work with the fertilizer giant Yara International ASA to use wind power to create hydrogen and turn it into ammonia. The project could produce about 75,000 tons of green ammonia a year, cutting Yara’s carbon footprint.

Green ammonia is seen as an option to store hydrogen or use it for industrial applications and transportation. Chemical fertilizers use ammonia, made up of nitrogen and hydrogen. The most common and cheapest way of making hydrogen today emits carbon dioxide.

The proposed plant in the Netherlands would use 100 megawatts of electrolyzers — machines powered by electricity that separate the hydrogen atoms in water from the oxygen. Orsted is currently building a 752-megawatt wind farm off the Dutch coast that could provide the facility with green power.

The green ammonia produced at the plant would be a small fraction of Yara’s demand, about 3% to 4% of the ammonia used at its factory in Sluiskil in the western Netherlands. But the scale would still make it one of the biggest green hydrogen facilities in the world.

“Green ammonia today doesn’t exist. It’s a market that will need to be created,” Sammy Van Den Broeck, Yara’s vice president for climate neutrality, said in an interview. “This is a first step into the trajectory of climate neutrality.”
