Ancillary Benefits of Carbon Capture and Storage

Ancillary benefits of Carbon Capture and Storage (CCS) are defined as positive effects of CCS deployment that are additional to the primary climate change mitigation effect through reduced carbon dioxide emissions. One category of ancillary benefits of CCS is the use of carbon dioxide for synthetic fuels, chemicals and plastics, building materials, and Enhanced Oil Recovery (EOR). A second category of ancillary benefits is related to removal of carbon dioxide from the atmosphere, which is deemed necessary in many climate policy scenarios, where CCS deployment is essential for two removal technologies, namely Bioenergy with CCS (BECCS) and Direct Air Capture (DAC). A third category is new industry opportunities associated with geological storage of carbon dioxide services, and production of carbon dioxide capture equipment. The last category examined is benefits of CCS for petroleum producing countries in a carbon-constrained world, since more of the resource rent from petroleum production can be kept by producers instead of being transferred to governments in consuming countries as revenue from taxing or sales of carbon dioxide emission allowances.
