5 MHI s KM CDR Process - R&D History Solvent Screening and Laboratory Testing (1990 Present) The first flue gas CO 2 capture R&D in the world aiming for Global Warming Mitigation. More than 200 solvents tested The Kansai Electric Power Co. Nanko Power Station Testing (1991 Present) > 20 solvents tested in 2 tpd pilot unit Downselected to KS-1 formulation for commercial projects 14,000 hours of direct testing to date MHI Hiroshima R&D Center ( ) Extensive testing in MHI s R&D center Facility includes coal boiler, AQCS, and 1 tpd CO 2 capture system Evaluated effects of coal PM, SOx, NOx, metals, and aerosols on solvent and process Facility currently being relocated to MHI Nagasaki R&D center J-Power Matsushima Station (2006) More than 6,000 hours of testing with 10 tpd CO 2 capture pilot plant from slip stream of 500 MW utility coal boiler Demonstrated long-term performance of solvent and process counter measures to coal fired flue gas impurities Plant Barry, Alabama Large Scale Demo ( ) Next slides 5

6 Large-Scale Coal Demonstration Project at Plant Barry (25MWeq) Proved technical performance of CCS on coal flue gas through joint demo. Funding for capture system from Southern Company, MHI and EPRI. CO 2 storage was part of Phase III: Anthropogenic CO 2 Injection into Aquifer Tests by SECARB. Designed to capture 500 metric tons per day of CO 2 at 90% capture efficiency. From : over 12,000 hours, over 250,000 metric tons captured, over 125,000 metric tons injected Verified Long-term Performance of KM CDR Process on Coal-fired Power Plants Confirmed constructability and operational performance of rectangular absorber design Confirmed utilities consumption and CO 2 product quality Confirmed VOC emissions and solvent consumption Confirmed long-term stable system operation Verified system performance under various flue gas conditions, coal characteristics, etc. 6

11 Petra Nova Project: CO 2 for EOR CO 2 Captured for Enhanced Oil Recovery (EOR) (Owner s scope) Compressed CO 2 is delivered by 81 mile CO 2 pipeline to the West Ranch oil field. Up to 1.4 million metric ton of CO 2 is annually injected into the West Ranch oil field. 11

13 Technical Key Massages 5,000 Metric Ton / D CO 2 capture Plant is available with commercial basis. MHI continue the efforts to reduce CO 2 capture costs. 99% CO 2 capture can be technically achieved. Biomass fired (or Coal Co Fired) plants with CCS is the only the practical solution for negative CO 2 emission. Therefore coal fired plants have to be left for future purposes. 13

14 Political Key Massages Incentives such as US Section 45Q tax credit are essential for commercial implementation of CCUS. CO 2 pipeline infrastructure prepared by Governmental sector will give great flexibility for both sellers and buyers of CO 2. Government support of reduced carbon energy products (i.e. oil production with CO 2 EOR, CO 2 free fuel (ammonia), low carbon electricity) with premiums or incentives. 14
