The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has developed three carbon capture retrofit database (CCRD) tools that provide high-level analysis on the incremental cost for retrofitting point sources with carbon dioxide (CO2) capture and/or compression systems. The tools also provide options to include the cost of implementing other plant emissions reduction technology improvements that may be required to comply with various regulations (e.g., Mercury and Air Toxic Standards [MATS][1] and New Source Performance Standards [NSPS][2]) when installing CO2 scrubbing technology, or aid in maximizing the efficiency of the installed CO2 removal technology.
