Yara's Sluiskil Plant Tests Carbon Capture's Real-World Limits

What happened

On September 7, 2026, Yara International switched on a new carbon-capture facility at its ammonia and fertilizer complex in Sluiskil, in the Dutch province of Zeeland, in a ceremony attended by Norwegian Prime Minister Jonas Gahr Støre, Dutch Prime Minister Rob Jetten and EU Climate Commissioner Wopke Hoekstra 91013. The plant is designed to capture and liquefy up to 800,000 metric tons of CO₂ a year from ammonia production, then ship it by sea to Norway, where Northern Lights will inject it roughly 2,600 meters beneath the seabed for permanent storage 78111213. Over a planned 15-year run, Yara expects to keep about 12 million tons of CO₂ out of the atmosphere 7111213.

Multiple outlets describe this as the first fully operational cross-border carbon capture, transport and storage chain — a CO₂ molecule captured in one country, shipped internationally, and permanently entombed in another 910. The gas is chilled to liquid form at Sluiskil, held in insulated tanks, loaded onto Northern Lights vessels built by adapting LPG-carrier technology, and sailed to the Øygarden terminal on Norway's west coast before traveling through a 100-kilometer subsea pipeline into the Aurora geological formation 10. Northern Lights — jointly owned by Equinor, Shell and TotalEnergies — first injected CO₂ into that formation in August 2025, using gas captured at a Heidelberg Materials cement plant in Brevik, Norway 10.

Why ammonia, and why now

Ammonia synthesis via the century-old Haber-Bosch process produces a concentrated, relatively pure CO₂ stream as a byproduct, which makes it one of the cheapest industrial sources to capture — an estimated $15 to $25 per ton, according to one detailed technical account, compared with $40 to $120 per ton for cement, steel and waste-to-energy plants 10. That distinction matters because it frames Sluiskil not as proof that carbon capture works everywhere, but as proof that it works where the underlying chemistry cooperates.

The project rested on a 2022 commercial agreement between Yara and Northern Lights followed by a binding contract tied to a November 2023 final investment decision, with construction and ramp-up preceding the 2026 inauguration 911. Norway's Longship program covered roughly 80% of Northern Lights' Phase 1 costs, and the EU's Connecting Europe Facility contributed €131 million to Northern Lights specifically, part of nearly €480 million spread across four European CO₂ transport-and-storage projects 10.

Startups, batteries, and the wider climate-tech map

The Sluiskil launch is a large industrial deployment rather than a startup story, but it establishes an infrastructure template that startups are racing to plug into. Direct-air-capture and modular-capture companies — Climeworks, Heirloom, CarbonCapture, and others building CO₂-to-fuel or CO₂-to-chemical conversion technology highlighted by the World Economic Forum, including D-CRBN, Dioxycle, eChemicles and Oxylus Energy — occupy a harder, more energy-intensive niche than industrial point-source capture, since ambient air holds far less CO₂ per unit volume than an ammonia plant's exhaust 15. One funding tracker puts total capital raised by carbon-removal startups since 2021 at $3.6 billion, with Climeworks alone accounting for more than $1 billion, or roughly a quarter of all identifiable CCUS startup equity, much of it underwritten by the U.S. 45Q tax credit, now worth $85 to $180 per ton depending on the pathway 14.

Elsewhere in climate tech, batteries dominate the capital tables. A market dataset tracking startup valuations lists battery and energy-storage companies as the best-funded subsector, with more than $11 billion in cumulative funding across firms like Redwood Materials, Group14 Technologies, Form Energy, ProLogium, Sila Nanotechnologies, StoreDot and Ample 1617. Their approaches diverge sharply: Redwood Materials recycles battery materials back into the supply chain; Group14 and Sila pursue silicon anodes for higher energy density; ProLogium and others chase solid-state chemistry; StoreDot and Greater Bay Technology target ultra-fast charging; Form Energy's iron-air batteries aim at long-duration grid storage, claiming up to 100 hours of discharge versus four to eight hours for conventional lithium-ion 161718. Separately, a Silicon Valley startup effort described in Forbes' Current Climate newsletter is working to close a materials gap in the battery supply chain, underscoring how much of the sector's activity sits upstream of the finished cell 2.

Underlying life-cycle research offers a check on both technologies' claims. The ICCT finds that battery-electric vehicles sold in 2025 produce about 73% lower life-cycle greenhouse-gas emissions than comparable gasoline cars — 63 grams of CO₂-equivalent per kilometer against 235 grams — even though battery manufacturing initially adds roughly 40% more upfront emissions than building a combustion vehicle; that gap closes within the first one to two years of driving, after about 17,000 kilometers 19. A companion ICCT report on battery sustainability finds that the electricity mix used to manufacture a battery pack can swing its carbon footprint by roughly 48% between coal-heavy and hydropower-heavy grids, and that recycling could cut battery-related emissions by close to 20% under optimized conditions — while cautioning that newer chemistries like solid-state and sodium-ion are not automatically cleaner than mature lithium-iron-phosphate or nickel-manganese-cobalt cells 20.

Where the reporting agrees

Across Yara's own releases, PR Newswire, Reuters (via Euronext), offshore-technology.com, energynews.pro and Tech Times, the core facts are consistent: an 800,000-ton annual capture capacity, a 2,600-meter storage depth off Øygarden, a projected 12-million-ton lifetime total, and a September 7, 2026 inauguration attended by Norwegian and Dutch leaders alongside the EU's climate commissioner 789101213. Every account frames the project as connecting capture, transport and storage into a single operating chain for the first time, and all treat ammonia's relatively pure CO₂ stream as the reason Sluiskil could go first. There is broad agreement, too, that the project depends heavily on public money and carbon-pricing incentives rather than standing on unsubsidized economics alone 910.

Where it doesn't

The clearest divergence concerns the "largest in Europe" claim itself. Yara, PR Newswire and offshore-technology.com present it largely as settled fact 7812, while energynews.pro and Tech Times explicitly flag that the superlative originates from Yara's and the EU Commission's own communications and has not been confirmed against any independent industry ranking 910. Tech Times goes furthest in stress-testing the story, citing a review finding that roughly 70% of announced CCS projects globally have failed to materialize — with an even higher failure rate in the electricity sector — and quoting University of Twente researcher Guus Dix questioning whether CCS costs have improved at all across the chemical process, piping and drilling involved 10. None of the celebratory releases from Yara, Northern Lights or the EU Commission engage with that skepticism; Reuters' coverage sticks to the physical and commercial facts without editorializing either way 13. On the ship count and cadence, Yara's own fact sheet cites two vessels making two loading trips weekly 11, while Tech Times' more granular account names four Northern Lights vessels delivered between 2024 and 2026 as part of the broader fleet, a difference likely reflecting fleet-wide capacity versus vessels dedicated specifically to the Sluiskil route 1011.

The read

The weight of the reporting supports treating Sluiskil as a genuine engineering and logistical milestone — the first time a complete international capture-to-storage chain has gone commercially operational — while resisting the temptation to read it as evidence that carbon capture has become broadly viable. The sources that dig deepest, particularly Tech Times, make the more defensible case: this is the easy version of the problem, solved with heavy public subsidy, in a sector (ammonia) whose emissions were always going to be the cheapest to grab. Cement, steel and waste-to-energy plants, which produce messier, more dilute CO₂ streams at far higher capture costs, remain untested at this scale. The honest synthesis of the record is that Sluiskil proves the pipes, ships and injection wells can work together across a border — not that the economics generalize. Climate tech's harder half, whether in carbon capture or in batteries, still lies in scaling the expensive cases, not the convenient ones.
