O&M Cost

← Previous | Next →

This is a standard O&M cost result screen. The chemical looping system has the following variable cost components:

•Sorbent: This is the annual cost of the sorbent used in the system. This is a function of the concentration of CO2 in the flue gas and the flue gas flow rate.

•Coal: This is the cost of coal.

•Caustic (NaOH): This is the cost of NaOH caustic used by the SO2 polisher.

•Waste Disposal: This is the waste disposal cost per year.

•Solid By-product Credit: This is the annual income from selling the solid by-product.

•Electricity: The cost of electricity consumed by the chemical looping system.

•Auxiliary Power Credit: This is the annual credit for power generated by the recovered heat.

•CO2 Transport: The CO2 captured at the power plant site has to be carried to the appropriate stor- age/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 cost is based on option chosen on the T&S Config parameter screen .

•Auxiliary CCS Cooling System: (Only shown when an Air Cooled Condenser is configured.) This is the cost of the auxiliary cooling system needed when an Air Cooled Condenser is used as the plant cooling system.
