During the House hearing, “Department of Energy Oversight: Status of Clean Coal Programs,” Rep. Joe Barton (R-Texas) asked Dr. Julio Friedmann, the deputy assistant secretary for clean coal at the Department of Energy, about the additional costs carbon capture and storage technology would bring to coal plants.
“My generic question is pretty straightforward. All of these carbon capture sequestration technologies – add cost to these coal plants could y’all give the committee, or the subcommittee, kind of a baseline estimate of how much it adds to the cost, does it double the cost, does it increase it by 25%, 50%, what’s the generic estimate?” Rep. Barton asked.
“The precise number will vary by plant, whether it’s sub-critical or supercritical, by coal rank, and by the kind of technology used,” said Friedman
Concerning the first generation of carbon capture and storage (CCS) technology to be implemented, Friedman added” we’re looking at something on the order of $70-90 a ton. In that context, that looks something like a 70-80% increase on the wholesale price of electricity.”
