The Cost of Carbon Capture
The second three inputs characterize the capture plant: • Incremental capital cost, in $/kg of CO 2 processed per hour; • Incremental cost of electricity due to operation and maintenance, in mills/kg of CO 2 processed; • Energy requirements of the capture process, in kWh/kg of CO 2 processed. The capture efficiency is usually about 90% in the studies reviewed.

Nuclear Power Economics | Nuclear Energy Costs - World ...
For nuclear power (2200 MWe plant), capital cost including financing (at a high discount rate) ranged from $7675 to $12,500 per kilowatt, and the LCOE accordingly varied from $129 to $198/MWh. For a 600 MWe coal plant the capital cost ranged from $3000 to $8400/kW, giving an LCOE of $60 to $143/MWh.
