Abstract
Government support for CCS-EOR projects is often contested on the grounds that the resulting increase in oil production undermines their environmental benefits. This paper summarizes a simple approach based on a marginal reasoning consistent with economic decision-making. It produces analytical formulas that account for the effects on the global oil market of incentivizing CCS-EOR. Our results suggest that, from an economic perspective, CCS-EOR is a technology that mitigates global emissions, but the emissions reduction is less than the stored quantity of CO2. Based on our results, we examine the size of the subsidies granted by the US Inflation Reduction Act for CCS-EOR projects.
