7 Coal Hurdle to use widely Coal has been used mainly as a boiler feedstock for electric power generation Gasification enable coal to be used for chemicals and liquid fuel production High CAPEX and CO 2 emissions are hurdles to use coal widely Coal Utilization Energy Triangle Coal Combustion Chemical Process Chemicals Feed Abundant Availability Reserves: 3 times of oil F-T Syncrude Coal Gasification Syngas (CO+H 2 ) IGCC Power Generation Not Cost Affordable Environ- Not Clean ment Coal Methanation SNG CTL Plant CAPEX: 4 times of oil refinery CO 2 Emission of CTL Plant: 6 times of Petroleum WTT 7

8 Coal Low Rank Coal When oil price goes up, high rank coal is not likely to be cheap anymore Low rank coal has stable price and huge reserve; big potential to be utilized $/ton 150 Historical Coal Prices WTI ($/barrel) Accounts over 50% of world coal reserves Proven Reserve 100 High Rank Coal High heating value Little impurity Lignite 18% Low Rank Coal Low heating value Many impurity 50 Already Occupied by Major Companies Bituminous, Anthracite 50% Sub- Bituminous Not developed yet / / / / / / /01 32% Source> US EIA, World Energy Council 8

10 What is Green Coal Technology? Technology breakthroughs the problems of coal utilization Coal is Huge Reserve Cheap Price Can be cleaned But, reality is Supply Issue Coal Monetization Costly to use High Cost of Emission Control Conventional High Rank Coal High Capital Cost Green Coal Low Rank Coal Reduce Capital Cost High Temperature CO 2 Intensive Low Temperature Reduce CO 2 Emission Innovate Efficiency and Reaction Pathway 10

11 Development Schedule Selection of KBR TRIG gasifier as a platform gasifier Pilot plant mechanical completion ( 10.10) and commissioning ( 11.01) Feasibility study for the commercial (2013 ~) ~ 2016~ Lab Scale Bench (0.05T/D) Pilot Plant (3T/D) 1 st Commercial Start-up (Plan) 2009~ DTR(Drop Tube) TBR(Thermo Balance) 2009~ Test for Element Technologies. Deduction of Application for P/P. 11

12 Transport Reactor Integrated Gasifier TM Advanced Circulating Fluidized Bed Suitable to Low Rank Coal Scalable Up to 4,000 Ton/Day with Single Train Negligible Tar Formation : Carbon Conversion >98% Reliable : Operating at < 980 ( <1800 ) No Spare Gasifier is Required Low Cost refractory lined Carbon Steel More Efficient due to Low O 2 Demand Low Water Consumption (no black water) (Source: KBR) 12

13 Pilot Plant Constructed through government project ( ~ 11.01) 13

14 Pilot Plant Coal Preparation Gasifier Gas Clean-Up Coal Hopper, Conveying Feeder Crusher, Bucket Elevator Dryer, Miller, Ash Collecting Gasifier -1 st, 2 nd Cyclone -Loop Seal, J-Leg - Riser, Standpipe Particle Collecting Devices H2S Removal Bed Activated Carbon Canister Ground Flare, Sour Water Drum 14

15 Operation of Pilot Plant 5 test runs by using 3 different coals were conducted in 2011 Through the troubleshooting, it shows stable gasification performance Heating & Combustion Mode Gasification Mode S/U : 1day O2 Gasification mode : 7 day Temp. S/D : 2day Pressure Steam O2 Syngas Composition at Steady State Jan May Jul Sep Dec CO2 H2 CO CH4 15

16 Future Plans Feedstock evaluation Studies Technology development for improved gasifier performance - Efficient drying of coal - Catalysts to activate gasification reaction - Optimization of system integration Testing of FT synthesis Feasibility study for the commercial projects 16
