7 Outline Why GTL can matter Conditions for gas resource and market development Conditions for GTL development 7

8 Why GTL can matter: The globalization of liquid fuel demand OECD Pacific OECD Europe OECD North America Africa projected fuel growth from 2006 to 2030 E. Europe/Eurasia Latin America Other Asia India Middle East China Source: IEA, WEO 2008 Million b/d 8

9 Resource and market factors in natural gas development Remote Market Access Proximate Small / Med Resource Scale Large Low Gas Production Costs High Low Gas Market Price High Low Oil Market Price High 9

10 Conditions for LNG infrastructure and market development Remote Market Access Proximate Small / Med Resource Scale Large Low Gas Production Costs High Low Gas Market Price High Low Oil Market Price High 10

11 LNG market variations $4.00 $8.50 $10.50 APPROXIMATE LANDED LNG PRICES PER MCF 11

12 Conditions for GTL infrastructure development Remote Market Access Proximate Small / Med Resource Scale Large Low Gas Production Costs High Low Gas Market Price High Low Oil Market Price High 12

13 U.S. oil has almost always been relatively expensive compared to gas Benchmark oil prices / benchmark gas prices Energy price parity

17 Distributed Gas-to-Liquids (GTL) Enabled by Microchannel Technology ARPA-E Energy Innovation Summit Feb. 28, 2011 Dr. Anna Lee Tonkovich Chief Technology Officer Velocys, Inc. / Oxford Catalysts

18 GTL Background Creating Synfuels using Fischer Tropsch Natural Gas Gas Recycle Steam Steam Reforming CO / H 2 Fischer Tropsch Products Hydro- Cracking Air H 2 Natural Gas H 2 O Diesel or Jet Fuel 18

19 Market Primed for GTL GTL = Arbitrage Spread: 1 bbl / 1,000 scf Opportunity: spread >10 Conventional LNG / GTL 4 73 >50 (in tcf) 5-50 North Am. spread > World-scale GTL/LNG plants need large fields Microchannel GTL , Small-scale GTL can unlock more gas 3,922 gas fields Distribution of gas fields outside US <0.1 Field size Source: IHS Energy Group,

20 U.S. Primed for GTL Shale Gas Production Expanding in U.S. Production increase: 1.4 TCF (2007) to 4.8 TCF (2020) Reserves estimated at 500 to 1,000 TCF 50B to 100B bbl oil Worth $3-4T as gas liquid fuel value >$10+T 20

21 GTL Today = World Scale Shell s Pearl GTL in Qatar ~$19B price tag 140,000 bpd + 120,000 bpd of NGL SASOL Oryx also in Qatar $1B for 34,000 bpd 60m tall, 2,200 ton reactors Chevron Escravos GTL in Nigeria $6B, ~4X original estimate 34,000 bpd, using SASOL technology ExxonMobil: Methanol to Gasoline New Plymouth, New Zealand ( 85-95) 14,500 bpd, 82% gasoline product 21

22 GTL Tomorrow = Small to Medium Scale Tap abundant U.S. gas resources Large scale economics at smaller capacity Many, less-expensive plants easier to finance Process intensification for attractive economics Intensify all key unit operations 22

23 Syngas Production Air NG/Steam Cyro ASU Reformer FT Reactor Separation / Upgrading Liquid Product 30% 30% 25% 15% Air NG/Steam OTM Syngas Reactor FT Reactor Separation / Upgrading Liquid Product Syngas Production with Ceramic Membranes Lower CAPEX/OPEX syngas production Status Demonstrated robust material performance Scaling technology to pilot system Future (opportunity for ARPA-E support) Integration with FT reactor Gas separation layers High strength porous support Low pressure air High pressure syngas 23
