claimThere are currently no commercially available services for CO2 storage, and while firms exist that conduct site characterizations and drill test wells, these activities involve high costs in time and money with no guarantee of a satisfactory outcome for CO2 storage.
claimSafety concerns regarding permanent geologic storage of CO2 include the potential for carbon leakage, loss of well integrity, induced seismicity, and potential human health or environmental impacts.
claimSaline formations are not as well identified or characterized as oil, gas, and coal reservoirs for the purpose of CO2 storage, according to the 2012 NACAP report.
claimOperational concerns regarding permanent geologic storage of CO2 include perceptions about possible effects on water tables and other issues related to caprock and injection operations.
claimElectric power utility regulators have expressed concerns that the current lack of certainty regarding suitable dedicated geologic CO2 storage sites is hampering the development of carbon capture technologies.
claimOperational concerns regarding CO2 capture and transport risks, as well as the safety and integrity of underground CO2 storage, act as major nonmarket barriers to permanent geologic storage of CO2.

procedureThe study tests how the spatial allocation of Carbon Dioxide Removal (CDR) technologies changes based on CO2 storage potential by conducting sensitivity analyses that restrict pipeline development and equate CO2 storage costs across regions.
claimThe authors' analysis excludes several Carbon Dioxide Removal (CDR) issues, including RD&D strategy, financing first-of-a-kind units, policy design, lifecycle emissions of biomass production, and geological characterization of CO2 storage and site selection.
claimThe spatial distribution of Carbon Dioxide Removal (CDR) technologies depends on factors with considerable regional variation, specifically biomass availability, suitable geologic CO2 storage sites, and technological cost and availability.
