Europe’s largest industrial carbon capture facility was inaugurated in Sluiskil, the Netherlands, on September 7, with the prime ministers of Norway and the Netherlands and the EU’s climate commissioner in attendance. Yara’s own CEO, Svein Tore Holsether, offered a more candid assessment than the ceremony’s framing: the project is, for now, primarily a way to avoid costs under the EU Emissions Trading System, and whether it becomes commercially viable at all depends on where carbon prices and demand for low-carbon ammonia land in the years ahead.
The facility can capture and liquefy up to 800,000 tons of CO2 annually from Yara’s ammonia production process, transported by ship to Norway’s Northern Lights joint venture and injected into a saline reservoir 2,600 meters beneath the seabed on the Norwegian continental shelf, with the arrangement expected to store roughly 12 million tons over 15 years under a binding commercial agreement signed in November 2023. That volume equals approximately half a percent of the Netherlands’ total annual greenhouse gas emissions, a fact Yara’s own communications acknowledge directly, against global fossil fuel CO2 emissions the Global Carbon Budget project estimated would surpass 42 billion tons in 2025. Holsether’s own remarks at the inauguration added a dimension the celebratory framing left out: asked whether the project would be profitable, he said that depends on the price of carbon and demand for low-carbon products, adding plainly, “if it isn’t profitable, you can’t do this at scale in Europe.” That is a direct statement that Sluiskil’s replicability elsewhere rests on external market conditions Yara does not control, not on the technology having already proven its economics.
Public funding covers a substantial share of the roughly 200 million euro project cost. The Dutch government contributed 30 million euros in direct support plus additional tax relief for Yara, together covering close to a third of total capital costs, while Northern Lights itself, the transport and storage infrastructure the entire arrangement depends on, was built with backing from the EU’s Connecting Europe Facility. Dutch Prime Minister Rob Jetten’s own comments at the inauguration acknowledged this directly, calling for “predictability in policy and an integrated CO2 market in Europe” as a precondition for other companies to scale up the same approach, language that describes a technology still dependent on continued public support rather than one operating on commercial terms alone.
The chemistry underlying Yara’s project is also more favorable to carbon capture than most of the industrial sources CCS ultimately needs to address. Ammonia production yields a highly concentrated, nearly pure stream of CO2 as a direct output of its process chemistry, making it one of the least difficult and least expensive capture cases in heavy industry. That stands in contrast to the combustion-based sources, cement kilns, power generation, biomass-fired heat plants, where CO2 arrives diluted within much larger volumes of flue gas, requiring more complex and costly separation technology. Northern Lights’ own customer pipeline illustrates the gap directly: Ørsted’s Danish power generation and Stockholm Exergi’s Swedish biomass district heating operations are both queued as future shippers, and each presents a materially harder capture chemistry than Yara’s ammonia stream. Decarbonization consultant François Le Scornet has described Sluiskil specifically as “an imperfect test case for the wide adoption of CCS,” a characterization consistent with the plant representing close to the easiest possible starting point for the technology rather than a proof point for its hardest applications.
Yara’s project is also not the actual debut of the Northern Lights storage chain, a detail that complicates some of the “world’s first” framing attached to this week’s inauguration. Heidelberg Materials’ cement plant in Brevik, Norway became Northern Lights’ inaugural shipper in August 2025, injecting the first CO2 into the Aurora reservoir using capture technology that, per the chain’s own customer roster, faces the more difficult cement-kiln chemistry Sluiskil’s ammonia stream avoids. What the Sluiskil inauguration specifically represents is the first cross-border link in that chain, CO2 captured in one country, shipped across international waters, and permanently stored beneath another, a genuine logistical and regulatory achievement given how difficult cross-border CO2 pipeline permitting has proven in parts of Europe. Whether that cross-border model extends successfully to the harder, more expensive capture chemistries Northern Lights’ pipeline is already queuing up, is, as one industry analyst put it, where the more consequential test now sits: not whether capture technology itself works, since ammonia production has demonstrated that clearly, but whether the storage hubs, transport infrastructure and offtake economics being built around projects like Sluiskil can support customers whose CO2 is far more difficult and costly to separate in the first place.
