Cost Analysis of Carbon Capture and Sequestration from U.S. Natural Gas-Fired Power Plants.

Despite increasing efforts to decarbonize the power sector, the utilization of natural gas-fired power plants is anticipated to continue. This study models existing solvent-based carbon capture technologies on natural gas-fired power plants, using site-specific emissions and regionally defined cost parameters to calculate the cost of CO avoided for two scenarios: delivery to and injection within reliable sequestration sites, and delivery and injection for the purpose of CO-enhanced oil recovery (EOR). Despite the application of credits from the existing federal tax code 45Q, a minimum incentive gap of roughly $38/tCO remains for the geologic sequestration of CO and $56/tCO for CO-EOR (before consideration of revenue generated from delivered CO contracts).
