3 California must dramatically decarbonize all sectors to meet its aggressive 2050 GHG reduction goals Study conducted by E3, Inc. California must: Dramatically improve energy efficiency in all sectors Switch energy use to electricity everywhere possible, including transportation Decarbonize the electricity sector using three approaches in combination: Renewable energy Nuclear power CCS Available from 3

4 A Balanced Approach to CO 2 Mitigation is Necessary Meeting California s Long-Term Greenhouse Gas Reduction Goals, E3 4

5 A blended, diversified approach reduces the risks of any particular technology We re eventually going to see need to employ CCS on a large scale in California if we are going to be able to meet the 2050 goals of AB32. -President Michael Peevey, California PUC, Feb 20,

6 location Elk Hills Bakersfield IGCC with fully integrated CO 2 capture based on GE Quench Gasification and GE 7F Syngas turbine technologies Located in Kern County, California (west of Bakersfield), in close proximity to water, gas and transmission infrastructure Adjacent to Occidental Elk Hills Field and CO 2 injection point for EOR & sequestration Proximity to feedstock transloading (western coal and petcoke from refineries) Low population density 6

9 Hydrogen Energy California Project Goals Generate low carbon base-load power to meet California s increasing power demand and GHG policy goals Produce hydrogen, a clean burning fuel that will be used to generate 250+ MW net of electricity 90% CO 2 capture: ~2 million tons for enhanced oil recovery and sequestration in nearby oil fields Operate with feedstock flexibility by utilizing a range of feedstocks from petroleum coke to western bituminous coal Preserve limited fresh water by utilizing 100% brackish water for plant needs, and Zero Liquid Discharge (ZLD) 9

10 HECA- Siting for success Siting CCS Projects more complicated than traditional power projects less than 5 miles away from Elk Hills reservoirs project linears (transmission, natural gas, water, solids disposal) are under 10 miles 10

11 HECA CO 2 Sink: Elk Hills Formation Over 1 billion tons of CO 2 storage capacity available in CA oilfields Elk Hills Reservoirs met all of the screening criteria Part of Strategic Petroleum Reserve from 1912 to 1998 Clear ownership history and site / well documentation multiple potential storage horizons, each with shale seals OXY of Elk Hills is the CO 2 recipient Pilot tests for CO 2 -EOR successful 11

12 HECA Project Progress Federal funding: $308M DOE Clean Coal Power Initiative- Round 3 Selected for negotiations July 2009, based on January 2009 application Cooperative Agreement signed with DOE September 2009 Cost share has begun State Funding: PUC Decision on SCE s $30M funding request Approved by 5-0 commissioners vote in February 2009 SCE Rate Recovery approved December 2009 Engineering Progress: Signed GE License Agreement, completed Process Design Package Selected AGR and SRU vendors Open solicitations : ASU and MAC (Main Automation Contractor) 12

13 HECA: Permitting Progress Application for Certification (AFC) with CEC May 2009: submitted Application For Certification Aug 2009: data adequacy achieved Sept 2009: Information hearing and HECA site visit completed Dec 2009: HECA and Oxy site visit with CA regulators, U.S. EPA and U.S. Senate staff Over 150 data requests addressed Preliminary Staff Assessment (Part 1) expected in mid-2010 NEPA Review Public scoping meeting held on April 14, 2010 in Bakersfield, CA CEC is Cooperating Agency for NEPA Process 13

15 Hydrogen Energy California Technology Advancements Exhibit commercial IGCC - CCS with Western coals and petcoke Captures 90% of carbon as CO 2 during steady state operation: >90% CO2 capture efficiency >2 million tons of CO 2 per year captured for EOR and sequestration Use of Rectisol technology in a solid-feed IGCC Use of high-hydrogen fueled F-class gas turbine Sulfur-emissions-free start-up and shutdown of an IGCC based on GE gasification technology, with minimal flaring 15

16 Hydrogen Energy California Technology Readiness Two Project objectives guide technology selection: Prove commercial scale IGCC-CCS operability at high capture rates and low criteria emissions over lifetime of operation Deliver a high reliability operating plant within a minimum period after initial startup Strategic approach: Select proven technology where available to minimize risk in component parts Use of GE quench gasification technology o Most proven solid fuel gasifier available, low technical risk o Advantageous for shift reaction and high % CO2 capture Rectisol has multiple operating units at similar scale to target H2S levels Comprehensive GE 7F syngas turbine testing program 16

17 HECA- Environmental Performance HECA will meet strict state and local air quality standards State of the art emission controls to achieve BACT emissions for IGCC SCR for NOx control; Rectisol for deep sulfur removal Minimize flaring and avoid sour syngas flaring + sulfur emissions-free startup technology licensed from Eastman Pollutant Technology employed Emission Limit NOx Diluent Injection, Selective Catalytic Reduction 4 ppm 15% O 2 CO Good Combustion Practice (GCP), CO Catalyst 3 ppm 15% O 2 PM 10 GCP, Gas Cleanup in AGR 20 lb/hr SO 2 Gas cleanup in AGR 5 ppmv total sulfur VOC CO Catalyst 1 ppm 15% O 2 NH 3 Selective Catalytic Reduction 5 ppm NH 3 slip 17

18 HECA- Industry/State/Federal Partnership Summary of Benefits Demonstrates commercial operation of 250 MW IGCC with 90% CO 2 capture, eliminating ~2 million tons of GHG emissions annually Reduces the pressure and need for natural gas with in-state, low-carbon baseload power Increases energy security by boosting production from California s own oilfields Received CCS support in stimulus bill (CCPI-3 award from US DOE) HECA would provide a stimulus to Kern County, creating over 1500 construction jobs and over 100 permanent jobs (We) became increasingly convinced of the value of the HECA Project, and its environmental benefits to California it really is a win-win-win-win-win.
