The dominant pattern today is a definitional problem the removals side keeps losing. Point-source carbon capture and storage keeps getting rhetorically bundled with carbon dioxide removal, and every time it happens the removal side pays the price: in policy attention, in capital allocation, and now in how researchers describe their own work. Eni’s half-billion-dollar CCUS financing and the soil-carbon researcher count both land inside that same fight.
The merger is a tax on removals
In Captain’s CDR Log #216 I walked through why the CCS-CDR conflation has stopped being a semantic annoyance and started being a material cost. When a fossil major raises capital for capture-at-the-stack and the press calls it “carbon removal,” three things happen. Buyers get confused about what a durable removal ton actually is. Regulators write frameworks that let avoided emissions count alongside net-negative tons. And the residual-only guardrail, the idea that CDR exists to clean up hard-to-abate emissions after fossil phase-out, quietly erodes.
To be precise: capture on a gas turbine flue stack reduces emissions from that stack. It does not remove legacy CO2 from the atmosphere. Both may be needed. They are not the same product, they do not have the same climate math, and they should not share a price signal or a policy bucket.
Eni’s $500M+ raise shows the shape of the problem
Eni CCUS Holding, the carbon capture arm spun out of the Italian oil and gas major Eni, closed more than $500 million in financing to expand European capture and storage. The projects target industrial point sources across Italy and the UK, with storage in depleted offshore reservoirs including the Ravenna hub and the HyNet cluster in Liverpool Bay.
This is CCS. It is emissions reduction at the source. It is useful for cement, steel, and refining flue gas where alternatives are limited. It is not carbon dioxide removal, and Eni’s own materials are careful about that distinction even where downstream coverage is not.
Two things to hold at once. First, half a billion dollars flowing into industrial decarbonisation infrastructure is a real signal that European capture is moving from pilot to deployment. Second, this capital did not go to durable removal. DAC (direct air capture), enhanced rock weathering, biochar, and mineralisation projects at comparable scale are still raising in the tens of millions, not the hundreds. The financing gap between capture-at-source and removal-from-air is widening, not closing, and the rhetorical merger makes that gap harder to see.
The residual-only constraint matters here. Eni is a fossil producer. Capture investments on their own operations do not offset continued extraction. They reduce the emissions intensity of specific facilities. Those are different claims and buyers of any resulting credits should treat them differently.
Soil carbon leads the researcher headcount
The 2025 CDR Researcher Census, which I analysed from public author and affiliation data across peer-reviewed CDR literature, puts soil carbon at 15,849 active researchers globally. That is the largest single pathway by headcount, ahead of afforestation and reforestation, ahead of ocean-based approaches, and well ahead of engineered pathways like DAC and BECCS (bioenergy with carbon capture and storage).
The caveat is important. Headcount is not tons delivered and not dollars deployed. Soil carbon suffers from durability questions, high MRV (measurement, reporting, verification) costs per ton, and reversal risk from land-use change. A large research base does not automatically translate to a large credit supply. What it does show is where the scientific labour is sitting, and it is sitting heavily in land-sector pathways with agricultural co-benefits.
The engineered removal community, roughly 2,000 to 4,000 researchers across DAC, mineralisation, and ocean alkalinity enhancement combined, is doing outsized work per capita on durability and MRV. But the raw research capacity for scaling soil, forest, and agricultural pathways dwarfs it. If the buyer side wants durable tons and the researcher side is concentrated on shorter-durability pathways, the mismatch will show up in supply curves five to ten years out.
What’s next
Two things to watch. First, whether the EU’s Carbon Removal Certification Framework implementing acts, expected in staged rollout through late 2026, preserve a clean line between permanent removals, temporary storage, and emission reductions. If those categories blur, Eni-style CCS financings will start pulling from removal-labelled buyer commitments. Second, whether the next Frontier Climate or NextGen CDR purchase round shifts allocation toward the soil and land-sector researcher base, or continues to concentrate in engineered durable pathways. The answer will tell us whether headcount or durability is currently winning the buyer argument.
