O&M Cost

← Previous | Next →

This is a standard O&M cost result screen. The Selexol CO2 capture system has the following variable cost components:

•Glycol: Selexol is a commercially available physical solvent that is a mixture of dimethyl ether and polyethylene glycol. This is the annual cost of the makeup solvent.

•Disposal: This is the annual cost of waste disposal for this process. It does not include the CO2 product stream disposal cost.

•Electricity: The cost of electricity consumed by the CO2 Selexol system.

•CO2 Transport: The CO2 captured at the power plant site has to be carried to the appropriate storage/disposal site. Transport of CO2 to a storage site is assumed to be via pipeline. This is the annual cost of maintaining those pipelines.

•CO2 Storage: Once the CO2 is captured, it needs to be securely stored (sequestered). This annual cost is based upon the storage option chosen.
