CCS front end engineering & design report:  American Electric Power Mountaineer CCS II Project. Phase 1
CCS front end engineering & design report: American Electric Power Mountaineer CCS II Project. Phase 1

30th January 2012

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

Topic(s): Carbon capture, Engineering and project delivery, Use and storage (CCUS)

This public design report provides select non-proprietary design information from the Phase I – Project Definition work products associated with the carbon capture and storage (CCS) system planned for installation at Appalachian Power Company’s Mountaineer Plant, located in New Haven, West Virginia, under US Department of Energy (DOE) Cooperative Agreement No. DE-FE002673.

The overall objective of the project is to design, build and operate a commercial-scale CCS system capable of treating a nominal 235 MWe slip stream of flue gas from the outlet duct of the Flue Gas Desulfurization system. The project was planned for execution in four phases: Phase I - Project Definition (February 2010 – September 2011), Phase II - Design and Permitting (October 2011 – December 2012), Phase III – Construction and Start-up (January 2013 – August 2015), and Phase IV – Operations (September 2015 – June 2019). AEP and its integrated project team successfully completed Phase I objectives, as outlined in the cooperative agreement, calling for:

  • the resolution of outstanding conditions with the DOE cooperative agreement;
  • project specific developmental activities (front end engineering and design (FEED));
  • the initiation of the NEPA process; and
  • the identification of exceptionally long lead time items.

The FEED package incorporated knowledge gained and lessons learnt (construction and operations related) from the Mountaineer Product Validation Facility and 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, flow diagrams and P&IDs.

Based on the work completed in the FEED package, the project team also:

  • developed a +/- 25 per cent cost estimate;
  • developed a detailed Phase II project schedule;
  • provided DOE with all information it needed to complete the NEPA process;
  • developed a multi prime construction contracting strategy for Phase III;
  • issued preliminary PFDs and overall mass and energy balances;
  • drilled a deep well for characterisation of subsurface geology at one of the alternative CO2 storage sites;
  • completed preliminary project design; and
  • submitted a decision point application regarding future project plans.

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

23rd January 2012

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

Topic(s): Carbon capture, Use and storage (CCUS)

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.

AEP Mountaineer CCS business case report
AEP Mountaineer CCS business case report

20th December 2011

Organisation(s): American Electric Power (AEP)

Topic(s): Business cases, Carbon capture, Use and storage (CCUS)

The purpose of this report is to examine the issues surrounding installation of carbon capture technology on AEP’s generating fleet based on lessons learnt from American Electric Power’s (AEP) project at Mountaineer coal-fired generating station. This report discusses the following issues associated with justification and use of this technology.

  • AEP is an investor owned utility with an obligation to provide electric service. The company is subject to governmental regulation which has implications on AEP’s ability to finance a commercial-scale CCS project.
  • Financial modelling completed by AEP and discussion of results. The report also uses output of modelling and looks at financial risks and the need for financial incentives to fund first-of-a-kind commercial-scale projects.
  • The difficulties associated with financing a project without government backing. Also the cost and use of the CO2 by-product and its competitiveness with other CO2 production sources.
  • AEP’s rationale surrounding its decision to suspend the Mountaineer CCS project.

AEP’s evaluation includes:

  • estimated capital expenses;
  • anticipated operations and maintenance costs;
  • cost of generating electricity following implementation and during operation of the CCS facility;
  • assumptions of legislative impacts;
  • consideration of optional CO2 sources, uses and revenue streams;
  • financial risk; and
  • other elements.

CO2 compression report. American Electric Power Mountaineer CCS II Project: Phase 1
CO2 compression report. American Electric Power Mountaineer CCS II Project: Phase 1

2nd December 2011

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

Topic(s): Carbon capture, CO2 capture, Use and storage (CCUS)

The study focused on commercially available, integrally-geared, inter-cooled, gas compression systems. The scope included all of the equipment required to compress and condition the captured CO2 for sequestration. Geologic characterisation information and actual operating data from the Mountaineer Chilled Ammonia Product Validation Facility (PVF), which operated from 2009 to 2011, provided injection parameters on which to base the design for the commercial-scale compression system. Equipment arrangements, auxiliary power demands, balance of plant integration, and capital and operating costs were considered in the evaluation of each compression system.

In the end, two arrangements were considered technically and economically feasible for implementation on the commercial-scale system. Further technical investigation in Phase II of the project would determine which arrangement would ultimately be selected. Both utilise compression of the CO2 to an intermediate condition, followed by variable-speed pumping to the final desired injection conditions. The compressor-pump arrangement allows for greater flexibility and higher operating efficiency throughout the life of the well, which is important based on the expected variability in injection pressure over the life of the injection wells – a key takeaway from the PVF operation effort, and design basis driver for the commercial-scale project.

Mountaineer Commercial Scale Carbon Capture and Storage (CCS) Project: CO2 storage report

22nd November 2011

Organisation(s): American Electric Power (AEP)

Topic(s): Carbon capture, CO2 storage, Use and storage (CCUS)

Understanding sub-surface geology is a time consuming and labor intensive process especially in an unexplored region. The Mountaineer plant region in West Virginia is not a part of the conventional oil and gas exploration region and hence there is considerable lack of pre-existing data.

Based on the experiences of drilling six deep wells, the associated geologic and geophysical work and the experience from running the CO2 injection operations, AEP has a better understanding of the sub-surface and a CO2 sequestration project.
