Why does one industrial CO2 project on the North Atlantic rim get a $2.6 billion sovereign check while another, on the opposite shore, gets sued by its pipe supplier? Same capture chemistry. Same decade. Same broad climate logic. Different geography, and the geography is doing almost all the work.
Aalborg Portland, Jutland. Denmark just committed $2.6 billion to retrofit Aalborg Portland’s cement plant with carbon capture, per a Tuoi Tre News report flagged by Chris Bataille. The captured CO2 lands in offshore North Sea pore space. The plant sits inside the EU ETS, with Danish state top-ups stacked on top. A working reference plant, Norway’s Brevik, is a short boat ride away.
Summit Carbon Solutions, Iowa. Once pitched as the largest CCS project in the US, Summit’s ethanol-CO2 pipeline is now in court with its pipe supplier Welspun over a $15 million dispute, still missing route approvals across Iowa and South Dakota. Capture would happen at corn-belt ethanol plants. Storage is planned in North Dakota. The line in between runs through thousands of private parcels, county by county.
The comparison, five dimensions:
- Storage geology. Denmark: offshore North Sea saline formations, sovereign-controlled seabed. Iowa-to-Dakota: onshore basin, fine for injection but the pipeline has to cross hostile surface tenure to get there.
- Carbon price. Denmark: EU ETS at roughly €70-80/t plus national subsidy. US: 45Q tax credit plus ethanol low-carbon fuel arbitrage, no binding price.
- Permitting. Denmark: centralized, one national authority. US Midwest: county-by-county route approval, state utility commissions, eminent domain fights.
- Reference plant. Aalborg builds on Brevik’s 50% capture proof point. Summit has no comparable nearby precedent at ethanol-CO2 trunkline scale.
- Public commitment. $2.6B for one Danish plant versus $18.5M from DOE for TerraSpark’s capture-enabled power project. Two orders of magnitude.
Where they converge. Both projects target genuinely hard-to-abate industrial CO2. Cement chemistry releases CO2 from limestone regardless of fuel, and ethanol fermentation produces a near-pure CO2 stream that is almost free to capture. Both are exactly the residual-emission use case CDR and CCS were designed for. Neither is a license to delay fossil phase-out, and the Danish deal in particular is squarely inside the cement-process-emissions envelope where there is no obvious substitute.
Where they diverge. Everything downstream of the capture skid. Chris Bataille (@chrisbataille.bsky.social on Bluesky) noted that Aalborg is “near FOAK because Norway’s Brevik cement plant has proved out the concept with a 50% capture rate, limited by available heat from the cement plant. It’s kind of exciting, actually.” That sentence captures the North Sea cluster effect. A Norwegian operator, a Danish operator, shared offshore storage, a shared regulator in spirit, and a shared carbon price. Iowa has none of that. It has a pipe supplier lawsuit and a permitting map that looks like a quilt.
The pattern is not unique to Europe. Pembina Institute (@pembina.org on Bluesky) flagged that “a major Canadian bank just made two long-term bets on carbon removal, both based in Canada. TD Bank, two 10-year deals.” Capital chases geography that lines up with local policy and local storage. The same logic Switzerland is now codifying with corporate removal milestone targets, layering procurement mandates on top of capture subsidies. No US state has the equivalent sitting over Summit’s route.
So what. If you’re underwriting CDR or CCS, the Aalborg/Summit split is the cleanest natural experiment on offer. Jurisdictions with offshore storage, a binding emissions trading system, and one-stop permitting are pulling away from jurisdictions relying on federal tax credits plus county-by-county route approval. Project finance models built on US 45Q assumptions alone are increasingly mispriced versus EU-anchored equivalents, where stacked revenue (ETS + national subsidy + emerging procurement mandates) carries the FOAK risk premium that 45Q cannot.
Two things to watch. Whether Aalborg breaks ground before EU-UK ETS linkage firms up, which would deepen the price signal further. And whether a Summit trial outcome pushes other Midwest CO2 pipeline developers to relocate flagship projects toward Gulf Coast geology, where Class VI permitting and existing pipeline corridors mute the social-license problem that Iowa keeps surfacing.
Capture tech is not the bottleneck. It hasn’t been for a while. Geology and social license are. Denmark has both. Iowa has neither, yet.
