Spiritus Signs Three Letters of Intent for On-Site Direct Air Capture CO2 Supply to US Oil and Gas Producers for Enhanced Oil Recovery

Spiritus, a direct air capture (DAC) company, has signed its first three letters of intent with oil and gas producers in the Rockies, Midwest, and U.S. Gulf Coast. The agreements cover over 3 million tonnes of annual CO2 demand for enhanced oil recovery (EOR), with projects potentially recovering more than 70 million incremental barrels of oil. Spiritus plans to deploy on-site DAC systems to supply CO2 at costs competitive with traditional sources, addressing a key constraint for EOR deployment. While the letters of intent mark a step toward long-term offtake agreements, questions remain about the energy source for on-site DAC and the net climate impact of using captured CO2 for EOR. The article highlights that the technology could unlock significant U.S. oil reserves, but the accounting for carbon removal versus oil production emissions will be critical for the climate case.

3 million tonnes of CO2 demand for EOR is a big number, but the key question is the cost of on-site DAC vs. buying from natural sources. Spiritus claims competitive with traditional supply, but they don't share the price. Anyone have a ballpark for what EOR operators pay for CO2 today?

Is CO2 used for EOR actually a removal? The CO2 ends up in the reservoir, but the oil extracted releases more emissions when burned. Net climate impact depends on the accounting. This might be more about oil production than carbon removal, which could be a problem for DAC credits.

The Rockies, Midwest, and Gulf Coast have very different grid mixes. On-site DAC will need a lot of power. If they're running on natural gas, the lifecycle emissions might not be that great. Did the article mention the energy source or just the CO2 output?

This could be a way to make 45Q more valuable, since EOR qualifies for the credit. But the 45Q rules require secure geologic storage, and EOR has its own leakage risks. The LOIs are just first step, but the real test is whether the CO2 stays underground.

Interesting to see DAC moving into EOR. On-site supply removes the pipeline bottleneck. But 70 million barrels of incremental oil is a lot of emissions. This feels like it could undermine the climate case for DAC unless the accounting is strict.
