19 E-MetaVenture, Inc. 19 A Word on GTL Diesel Supply Projections A large number of potential projects; only a small fraction likely to be built Qatar: self-described GTL capital –Oryx I: 2006 start up; March 2007 upgrader on line, May st product lift –Shell Pearl: 2009 (cost issues: $18 billion) –ExxonMobil: 2011 (canceled Feb. 2007) –Marathon, ConcoPhillips on hold per Qatar government temporary moratorium— likely to hold at least until 2009 Nigeria: –Escravos (Sasol/Chevron): under construction (delays and cost increase) California Energy Commission estimate (early 2000s): –2010: 75 MBD global GTL diesel capacity –2015: 388 MBD –2020: 800 MBD Sasol Chevron estimate: 600 MBD by

20 E-MetaVenture, Inc. 20 More on CTL Diesel Projections Global US (Baker and O’Brien study): – : 4-6 large-scale (>40 MBD) CTL in Western US –Some smaller plants under consideration in the Eastern US Potential: 250 MBD of middle distillates PRC : –A number of projects under study/planning/construction Example: 20 MBD plant in Inner Mongolia –CTL considered a key component of the PRCs overall, long-term energy strategy –A new key issue: recent environmental concerns of the PRC government –Projected (Robinson and Tatterson, OGJ Feb 2007 study): as much as 160 MBD liquid fuels Others: various projects under study/planning 2020 Hand-waving estimate (global): MBD 2030: 600-1,000 MBD—many unknown factors

21 E-MetaVenture, Inc. 21 What Impact will CTL have on… Coal market? Proved reserves, production, production increase capability Liquid fuels market? Supply/demand, change in other sources –Diesel –Jet –Naphtha (for cracking or blending) US v. worldwide Regional markets A word on specialty products: lubes and waxes Environmental impact Some factors affecting CTL growth: - Petroleum prices -Capital availability - E&C resources - Technology - Movement on CCS - Incentives and regulations

22 E-MetaVenture, Inc. 22 Policy Action (1) Regulations and Incentives—Key Factor Multiple forms of incentives under consideration (or in effect) in various jurisdictions. Include: –Direct subsidies or price guarantees Example: 2005 Federal Transportation Bill—$0.50/gallon of FT naphtha and diesel. –Loan guarantees Example: EPAct 2005—loan guarantees for gasification projects with < 65% output as electricity. –Investment tax credit EPAct 2005—20% credit applied to first $650MM investment during first year of operation

23 E-MetaVenture, Inc. 23 Policy Action (2) Regulations and Incentives—Key Factor Other incentives: –USAF Synthetic Fuel Initiative: successfully tested 50/50 Syntroleum FT fuel; targeting 50% synfuel use (domestic) by 2016; awarded 7,500 Bbl FT jet fuel for –Government funding of R&D and demonstration units Environmental regulations/incentives: –Multiple on emissions from plant and fuel –Multiple on fuel quality –EU: Emissions Trading Scheme –Voluntary emissions trading markets (e.g., Chicago Climate Exchange) –US State initiatives (e.g., California, several NE States) In flux. Subject to lobbying by interest groups on all sides.

ROI16.8 % Simple Payout6 years 67% 12% 5% 16%

26 E-MetaVenture, Inc. 26 Driver: Environmental Concerns (1) As we go from lighter hydrocarbon resources (Natural Gas) to heavier (Crude Oils) to heaviest (Coal) –C/H increases –More CO 2 made during conversion to useable fuels KEY POINT: every single coal carbon molecule, when converted to fuel, will eventually end up in CO 2 –Question is NOT whether we make CO 2 –Rather, it IS where we make CO 2 and what we do with it –(Same applies to natural gas and crude oil) Key: Capture, Compress, Transport (pipeline), Sequester (“CCS”) –Multiple sequestration options under consideration

27 E-MetaVenture, Inc. 27 Driver: Environmental Concerns (2) Concern: All agree that CCS is necessary for CTL but major parties do not incorporate the cost of CCS in their economics Concern: Though CTL+CCS compare well with oil refining in terms of CO 2 emissions, there are other options (e.g., BTL, nuclear, wind) with significantly lower CO 2 emissions (Concern: Some sequestration options are technically unproven or risky)

28 E-MetaVenture, Inc. 28 CO 2 from CTL Given production of a typical 0.65 ton CO 2 per Bbl of liquid products –50,000 BPD plant: 11.3 million tons CO 2 /year Question: –Is this significant? –How important is it to capture, compress, transport, and sequester (CCS)?

29 E-MetaVenture, Inc. 29 Worldwide Large Stationary CO 2 Sources ProcessNumber of Sources Emissions (million tons CO 2 /year) Power4,94210,539 Cement Production1, Refineries Iron and Steel Industry Petrochemicals Industry Oil and Gas ProcessingNot Available50 Other Fossil Fuels9033 Bioethanol and Bioenergy30391 TOTAL7,88713,466 Intergovernmental Panel on Climate Change (2005)

30 E-MetaVenture, Inc. 30 CO 2 Emission Projections from CTL Typical CCS in the context of CTL: 80-90% CO 2 emission reduction –Recovers as much as 95% of the CO 2 –However, CCS uses energy  lower net reduction CTL with no CCS: emissions worse than refineries, better than coal-fired power plants CTL with CCS: emissions on par with refineries Consider earlier EIA US CTL projections: Projected Emissions from CTL (million tons CO 2 /years) without CCSwith CCS CTL Emissions as % 2005 Global Stationary Sources

31 E-MetaVenture, Inc. 31 CO 2 Capture, Compression, Transport, Sequestration (CCS) (1) Capture includes separation/concentration, treating (e.g., dehydration), etc. –Mature technology used extensively in gas plants and refineries worldwide Compression: to pressure acceptable to pipeline Transport—a number of factors –Distance –Tons per year – millions of tons per year: pipeline most economical –>1000 km + 2,500 km pipelines transporting > 40 million tons of CO 2 per year in the US

32 E-MetaVenture, Inc. 32 CO 2 Capture, Compression, Transport, Sequestration (CCS) (2) Sequestration can involve –Use in enhanced oil recovery (EOR) Example: currently, in US, 30 millions tons per year CO 2 is injected for EOR applications –Injection in depleted oil/gas fields or other suitable geologic formations Most likely option (largest capacity, location, stability/leak) Current example: 1 million tons per year CO 2 from Sleipner gas field is injected into saline aquifer under North Sea –Ocean storage In R&D; Technical issues –Conversion to inorganic carbonates or direct industrial use Small In essence: every one of the elements in the CCS chain is tested/run-commercially. However, not all together in one chain. –Very active area: R&D as well as commercial testing –Very high likelihood of technical success –QUESTION: impact on economics?

33 E-MetaVenture, Inc. 33 Economics of CTL + CCS CCS economics vary wildly, depending on factors such as capture process specifics, pipeline length, injection reservoir type and depth, etc. One study (IPCC 2005) (incl. amortized add’l capital): –Capture from power plant: $15-75/ton CO 2 –Transport (250 km): $1-8 –Geological storage (excl. remediation/liability): $0.5-8 Another study (MIT 2007): –Capture/compression: $25/ton CO 2 –Transportation/storage: $5 A third study (Australia 2006) (capital cost for 0.5 million TPY CO 2, equiv. to approx. 2,200 BPD with 50 km pipeline): –Capture: $25 MM –Compression: $8 MM –Pipeline: $15 MM –Sequestration: $3 MM –Net operating cost: $24/ton CO 2 captured (incl. amortized capital)

34 E-MetaVenture, Inc. 34 Rough CTL+CCS Economics 50,000 BPD* Consider 50,000 BPD CTL Addition of CCS (incl. 50 km pipeline): –$300 MM extra to TIC –Or $230 MM/year to operating costs (including amortized TIC addition) CaseCTLCTL+CCS ROI16.8 %11.3 % Simple Payout6 years9 years * One scenario. For discussion purposes only. Results depend on a number of variables and parameters.

35 E-MetaVenture, Inc. 35 Summary Significant new interest in CTL Many parties—pro and con—in a number of countries –Energy security and strategy, environmental impact, product quality Mature technology; many variable affecting economics Large number of projects—mostly in study; a few in design or construction Projection for CTL diesel suggests 1-2% of demand by 2020, 6-7% by 2030 Capital intensive but multiple studies show potential for reasonable economics Environmental impact key—CO 2 capture, compression, transmission, sequestration
