On approximately 7 September 2026, Yara Sluiskil inaugurated Europe’s largest commercial carbon capture and storage project at its Dutch fertiliser plant, locking in 800,000 tonnes of CO₂ per year for subsea storage in Norway. The scale matters beyond the nitrogen sector: it demonstrates that industrial-grade, continuously available CO₂ streams can be captured and routed at commercial volumes—exactly the feedstock logic underpinning green synthetic methanol for deep-sea shipping.

CO₂ as Feedstock, Not Just Waste

The dominant narrative around CCS has long centred on permanent geological sequestration. Yara Sluiskil’s project fits that model: captured CO₂ is piped offshore and stored in Norwegian subsea formations. Critics from Transport & Environment and beyond argue that CCS at industrial sites primarily extends the life of fossil-intensive processes rather than delivering net decarbonisation. That objection has merit at the system level and should not be glossed over. However, for e-methanol producers, the more consequential question is whether large, stable, cost-competitive CO₂ point sources can be co-located with—or economically piped to—electrolysis and methanol synthesis capacity. An 800,000 t/yr stream from a single plant answers that question affirmatively at industrial scale.

Synthetic methanol chemistry requires roughly 1.37 tonnes of CO₂ per tonne of methanol output. At the Yara Sluiskil capture rate, the CO₂ stream could in principle supply feedstock for approximately 580,000 t/yr of e-methanol—enough to fuel a significant portion of a mid-size container shipping fleet. The bottleneck is not CO₂ availability; it is green hydrogen supply and the capital cost of synthesis units. That reframing changes where investment pressure should sit.

DAC as the Purer but Costlier Alternative

Climeworks’ Mammoth plant in Iceland offers a contrasting data point: 675 t CO₂ removed in H1 2026, roughly six times its output a year earlier, and at a declining unit cost. Direct air capture carries the advantage of feedstock carbon that is categorically additional—no association with a fossil industrial process—which strengthens RFNBO compliance arguments under RED III and FuelEU Maritime. But Mammoth’s H1 2026 figure also illustrates the scale gap: 675 t in six months versus 400,000 t in the same period at Yara Sluiskil. For maritime fuel volumes in the near term, point-source industrial CO₂ remains the pragmatic supply route, with DAC feeding premium, compliance-sensitive tranches.

The AI-driven optimisation tools now applied to DAC sorbent cycling and electrolyser load-following are narrowing the cost gap faster than linear projections suggested. Process digital twins that co-optimise CO₂ capture rate, compressor duty, and hydrogen delivery timing are among the highest-value applications in the e-methanol production stack—directly relevant to the technical and data analysis that defines this portal’s scope.

Implications for FuelEU Maritime and the Maersk Supply Chain

FuelEU Maritime’s greenhouse-gas intensity targets tighten progressively from 2025 through 2050, with e-methanol one of the few drop-in-capable fuels that can meet the 2030 and 2035 thresholds without engine redesign on dual-fuel vessels. Maersk has publicly committed to green methanol bunkering along its key corridors, with the Kassoe facility in Denmark positioned as a northern European supply hub. The critical path for Kassoe-scale production is securing verified, low-carbon CO₂ at sufficient volume. Industrial CCS projects of the Yara Sluiskil type—provided their CO₂ accounting meets the RFNBO sub-criteria under RED III—could serve as bridge supply until purpose-built DAC capacity scales. Regulatory clarity on whether point-source industrial CO₂ qualifies under FuelEU Maritime’s well-to-wake accounting remains the outstanding legal question that compliance officers must track.

Bottom Line

Yara Sluiskil’s 800,000 t/yr CCS inauguration and Climeworks’ accelerating DAC output together define the two ends of the CO₂ supply spectrum for e-methanol: high-volume industrial point sources available now, and expanding direct-air-capture capacity that satisfies stricter RFNBO provenance requirements. For operators planning FuelEU Maritime compliance strategies around methanol bunkering—whether at Kassoe or elsewhere—the decisive variable is no longer whether CO₂ can be captured at scale, but which CO₂ stream qualifies under the applicable regulatory framework and at what delivered cost per tonne.
