CCS lessons learned report: American Electric Power. Mountaineer CCS II Project: phase 1

Organisation: Global CCS Institute, American Electric Power (AEP)

The front end engineering and design (FEED) package developed within Phase I incorporated knowledge gained and lessons learnt (construction, operations, and process related) from the 20 MWe pilot Product Validation Facility (PVF) project for both the CO2 capture and storage systems. The design package also established the fit, form, and function of the project including design criteria, mass and energy balances, plot plans, general arrangement drawings, electrical one-lines, process flow diagrams and P&IDs.

The work completed in Phase I continues the advancement of Alstom’s CAP technology toward commercial demonstration at the intended scale. The completed FEED package also provides a sound basis for completion of the project when conditions warrant the continuation of this or a similar project elsewhere. The lessons learnt, insights, and exemplary practices shared within this report should benefit other CCS projects.
