1 Carbon Capture and Sequestration: Kiewit s Petra Nova CCS Project AWMA Midwest Section Environmental Technical Conference February 4, 2015 Mitchell Krasnopoler Kiewit Engineering 1 & Design Co.

2 Other Clean Coal Power Initiative Round III Projects (2009) Mountaineer Carbon Dioxide Capture and Storage Demonstration (Phase 2 of a Clean Coal project) AEP Mountaineer Power Plant 235 MW Flue Gas Stream DOE Share: $334 million Alstom Chilled Ammonia July 2011 AEP canceled this because of economics and lack of clear policy on CO 2 Phase 1: 20 MW CCS Facility at Mountaineer: Sep to May 2011, AEP operated the first fully-integrated CCS project at an existing coal-fueled power plant. Operated more than 6,500 hours Captured more than 50,000 metric tons of CO 2 Stored more than 37,000 metric tons of CO 2 2

3 Other Clean Coal Power Initiative Round III Projects (continued) Southern Company Carbon Capture and Sequestration Demonstration Southern Company, Plant Barry DOE Share: $295 million Feb Southern Company withdrew from the CCPI Phase 1 25 MW flue gas stream at Plant Barry: Captured CO 2 in June 2011 and sequestering CO 2 underground in August 2012 MHI KM CDR Process Basin Electric Power CCS Demonstration Antelope Valley Station 120 MW flue gas stream 25% of on unit s CO 2 Powerspan ECO2 (ammonia-based) process DOE share $100 million Put on hold Dec due to economics 3

4 Petra Nova CCS Project Timeline NRG application to DOE for funding through DOE s Clean Coal Power Initiative Round III using Fluor s EconamineFG Plus SM Process. NRG application for larger 240 MW project. DOE approves this. Applied for Air Permit MOU with Powerspan using their process DOE awards NRG $154 million for 60 MW demonstration using Fluor s Econamine FG Plus SM Process. 4

8 Petra Nova / WA Parish - Carbon Capture This will be one of the largest Post Combustion Carbon Capture System (CCS) in the world at 240 MW (5,000 tpd). It will be constructed at WA Parish (just outside Houston, TX) to be used for enhanced oil recovery (EOR) operations on the Texas Gulf Coast beginning with the West Ranch oilfield in $1 billion project Component Project Size Location Capture Technology Detail 240MW slipstream off of Unit 8, 650 MW unit ( 5,000 tpd) WA Parish Power Plant - Thompsons, TX (about 25 miles SW of Houston, TX) MHIA's KM-CDR advanced amine-based C02 absorption technology Enhanced Oil Recovery (EOR) Capital Sources EOR is expected to boost oil production at the West Ranch oilfield from around 500 barrels per day to approximately 15,000 barrels per day. CO 2 will be transported in and 82-mile pipeline. 3 Equity Partners, Bank Finance support, DOE Grant Schedule 3 year construction effort. Startup late 2016 to early

10 Petra Nova / WA Parish - Project Overview 10

11 Typical Integration of CCS v. Petra Nova Typical Steam for the CCS is from the turbine steam cycle: IP to LP Turbine. The changes the steam cycle may result in offdesign operating conditions. Electricity is from the unit Net electrical output is reduced by about 30% Petra Nova Steam and electricity for the CCS is from the combustion turbine and HRSG The same amount of steam and electricity is needed but the CT/HRSG is more efficient and the coal unit s steam cycle is not changed 11

19 Conclusion The Petra Nova CCS Project is one of the few that is going forward. At 240 MW it is one of the largest CCS Projects in the world The economics depend on the use of the captured CO 2 for EOR. The use of the GT/HRSG for steam and electricity has benefits 19
