On 12/14/15, UtilityDIVE reported that a new economic analysis of carbon capture and sequestration (CCS) concluded that it is more expensive and less efficient than estimated in a landmark 1991 Electric Power Research Institute (EPRI) study. “University of Michigan researchers say the 1991 EPRI pilot study put the increased annual cost of a CCS-equipped plant over a conventional plant at $29 million but, because capturing the emissions would require increased burning of coal, the actual additional cost is closer to $126 million annually. At this cost – more than four times the original estimate – a solar power plant with comparable generation capacity would be cost-competitive with CCS, according to analysis co-author Sarang Supekar. Wind, he added, is already less expensive than a new coal plant.” More on this is at Carbon capture too costly, so leave coal in the ground, say researchers.
