Captain Drawdown’s daily logbook on every CDR story, paper, and expert voice — so you don’t have to read them all.

The story

California Resources Corporation (CRC) injected the first molecules of CO2 into Carbon TerraVault I (CTV I) this week, opening the state’s first operational geologic storage project at the Elk Hills field in Kern County, as reported in California Launches First Operational Carbon Storage Project. It matters because California legislated SB 905 in 2022 to govern CO2 injection and has been waiting on a permitted, operating well ever since. Three years of statute, federal Class VI processing, county conditional use approvals, and reservoir characterization just collapsed into a single open valve. The continental storage map, which had Quest in Alberta and a handful of Gulf Coast projects, just added a West Coast node.

The mechanism

CTV I is not a saline aquifer wildcat. It is a depleted oil and gas reservoir CRC has operated for decades. That distinction is the whole story. The operator already owns the surface rights, the legacy well bores, the 3D seismic, the production history that tells you exactly where the caprock seals and where it leaks, and the institutional muscle memory of pressure management. Converting a depleted field to a storage asset still requires re-completing wells to CO2-rated metallurgy, plugging legacy penetrations that would otherwise be leak paths, and standing up measurement, reporting, and verification (MRV — the monitoring stack regulators require to confirm CO2 stays put). But the geology question, the one that takes greenfield developers two to four years and tens of millions in characterization, was answered by sixty years of oil production data.

The market angle

The unit economics tilt sharply toward legacy operators. A greenfield Class VI developer drilling into a saline aquifer spends roughly $40-80M on characterization and stratigraphic wells before a permit application is even credible, and then waits four to six years for Environmental Protection Agency (EPA) review. CRC compressed both the science and the queue by bringing a known reservoir and an operator with regulatory standing. Storage pricing in current offtake contracts runs $20-40 per tonne for the sequestration layer alone, which means a 1.5 million tonne per year hub like CTV I targets $30-60M in annual storage revenue at full ramp, against capital expenditure (CapEx, the upfront build cost) that is materially lower than a comparable saline project because the wells already exist. That margin profile is why LSB Moves Toward Full Ownership Of El Dorado Carbon Capture Project reads as a parallel signal: capture-side operators are consolidating equity at the same moment storage-side operators are proving up assets. The joint-venture phase is ending.

Policy and regulatory context

CTV I had to clear four stacked regimes: EPA Class VI primacy (California does not have it, so the federal permit took years), SB 905 implementation rules from the California Air Resources Board, Kern County conditional use permits, and the Inflation Reduction Act’s 45Q tax credit eligibility framework that determines whether stored tonnes are worth $85 each. The fragility of that stack is what makes this week’s other big policy story so resonant. Twenty-one European industry groups petitioned for phased CO2 transport regulation, a reminder that getting molecules to the wellhead at scale is the unsolved problem on both continents. The injection step works. The pipeline economics, the cross-border accounting, the shared-corridor permitting, none of those are settled.

What experts are saying

David Ho (@davidho.bsky.social on Bluesky) framed the prerequisite directly: “CDR will never happen without governments investing in and conducting R&D, negotiating governance, garnering public support, etc.” CTV I is the proof case. Every step from SB 905 to the EPA permit to the county hearing was a governance artifact, not an engineering one.

Pembina Institute (@pembina.org on Bluesky) noted that “Canada’s carbon removal industry is accelerating fast. 3× growth in 2025, 1+ million tonnes of CO₂ removed, contracts up 73% year over year.” Read continentally, CTV I is the US data point that lets the West Coast plot on the same curve.

The counter-argument

Skeptics will say CTV I is unreplicable. The Elk Hills advantage, decades of operator tenure on a single reservoir, exists at maybe a dozen US fields. Most depleted reservoirs are fragmented across operators, have unmapped legacy penetrations from the 1920s-1950s, or sit under populations who will not approve a conditional use permit at any price. The bull case for storage hubs may be a bull case for five operators, not fifty. There is also a moral hazard concern worth naming. Storage in a field still producing oil cannot become cover for delayed fossil phase-out. CDR is for hard-to-abate residual emissions only, and CTV I should be measured against that constraint every quarter.

Verdict

The binding constraint on US storage is not Class VI in the abstract. It is the seven-year choreography of converting a known reservoir into a regulated injection asset, and that choreography overwhelmingly favors incumbent oil and gas operators. For bioenergy with carbon capture (BECCS), DAC, and point-source capture developers, the implication is uncomfortable: the fastest path to a permitted tonne runs through the people who pulled the hydrocarbons out in the first place. Parallel work like Aquaterra Energy Advances RAF System For UK CCS project shows the offshore saline template still moving, but onshore in the US, the depleted-field route just got a working reference. Watch CRC’s injection rates and MRV disclosures over the next two quarters, and watch whether CTV II through V move at the same pace. If they do, the storage layer of the CDR stack will look very different in 2028 than the greenfield-Class-VI thesis predicted in 2022. For operators thinking through where storage fits alongside removal pathways, our primer How Can Direct Air Capture Scale to Deliver Real Carbon Removal for Climate Solutions lays out the dependency.
