Total cost of carbon capture and storage implemented at a regional scale: northeastern and midwestern United States.

We model the costs of carbon capture and storage (CCS) in subsurface geological formations for emissions from 138 northeastern and midwestern electricity-generating power plants. The analysis suggests coal-sourced CO emissions can be stored in this region at a cost of $52-$60 ton, whereas the cost to store emission from natural-gas-fired plants ranges from approximately $80 to $90. Storing emissions offshore increases the lowest total costs of CCS to over $60 per ton of CO for coal.
