  1. Fuel Cells An Emerging High-Technology Industry Rodger McKain, PhD 4/22/2006

  2. Energy Sets the Scene

  3. Setting the Scene for Fuel Cells: Petroleum supply, consumption, and imports, 1970-2025 (million barrels per day) 13 million Bbls/d US EIA 2005

  4. Setting the Scene for Fuel Cells: Petroleum supply, consumption, and imports, 1970-2025 (million barrels per day) 60% 71% US EIA 2005

  5. Primary energy use by fuel, 2003-2025 (quadrillion Btu) 1 quad = 170 million bbls = 1 trillion SCF (nat gas) = 45 million tons (coal)

  6. Fuel Cells: An Old Technology Provides New Solutions

  7. First Communication of Fuel Cell Related Phenomena “I cannot but regard the experiment as an important one…” William Grove to Michael Faraday October 22, 1842

  12. Fuel Cell Impact (from Hydrogen Economy Statements) • Clean environment • Reduced Global Warming • Energy independence • National Infrastructure Security • Low cost, reliable electrical power

  13. Regulated Emissions Comparison:Coal Fired Utility vs. PA Fuel Cell

  14. Fuel Cell System Trends Compared with other Distributed Generation Technologies 70 Combined Cycle 60 Carbonate Fuel Cell Solid Oxide Fuel Cells 50 PAFC Aero Gas Turbines 40 Electrical Generation Efficiency %LHV PEM Fuel Cell 30 Industrial Gas Turbine 20 IC Engines Stirling Engine 10 Microturbines 0 1 10 100 1,000 10,000 100,000 500,000 Residential Commercial Industrial Wholesale Size in kW

  15. Hydrogen Production • Principle Sources of Hydrogen • Hydrocarbons (natural gas and crude oil) • Water • Conversion Technology • Steam Methane Reforming (commercial) • Water Electrolysis (commercial) • Methane Pyrolysis (small scale) • Water-Sulfur-Iodide Process (small scale)

  16. Hydrogen Production Dilemma • 13 million barrels crude oil per day used in transportation – equivalent to 1.46 billion pounds per day hydrogen • This would require doubling the total US power production (850 GWe to 1780 GWe) if hydrogen were produced by conventional electrolysis. (assume 1 MW per 1000 lbs and efficiency improvements) OR • This would require 23 trillion cubic feet of natural gas per year - approximately 110% of the 2002 total US consumption, nearly doubling the total natural gas requirement.

  17. Hydrogen Production Solutions • Near Term (small volumes) • Conventional technology distributed to point of use • Fueling stations (hydrocarbon reforming or water electrolysis) • Long Term (large volumes) • High Temperature gas Cooled Nuclear Reactor – boost electrolysis efficiency from 20+% to 40+%. (Reduce power requirement by half) • FutureGen – Hydrogen and power from coal • Solar Cell Direct Electrolysis

  18. Are Fuel Cell Powered Cars Really More Efficient? 40 100 Energy Units IC Engine 40% Power Train 37.5% 15 Conventional Car 60 20 Idling 5 Friction - 60 Units H2 production 20 40 Energy Units Fuel Cell 50% Direct Drive 75% 15 Fuel Cell Car 20 0 Idling 5 Friction

  19. Technology Commercialization Conundrum • Public Expectations are high • But, Success Rates are less than 30% • And, Success generally takes longer and costs more • Fuel Cell system OEM’s will determine the future • Much more investment is required • Development phase is more costly than anticipated • Strategic development is likely to dominate • But, focus is on suppliers and entrepreneurs • Basis for a hard, clear-eyed review of the fuel cell opportunity • Role of OEM’s • Public expectations • Government and NPO involvement

  20. When Will Fuel Cells Be Available?(An Ohio View) Source: Projections represent Taratec Corporation’s estimate of market activity”based on input from industry analysts and information provided in executive interviews.

  21. Today’s Technology Cost Comparison Watts Sector Application $/kW 0.1 – 1.0 Biomedical Autonomous power for 105 sensors and implants 1 – 100 Electronics Battery replacement 104 100 - 10,000 Communications Battery replacement 103 – 104 Cell tower stationary power 5,000 - Transportation Propulsion 101 – 102 100,000 Auxiliary Power Units > 10,000 Stationary power Emergency backup 102 – 103 grid supplement

  22. Market Projections Portable Power leads the way Military/Aerospace Vehicle Stationary Auxiliary Portable

  23. Public Expectations • Set by “soft industry” successes • Dominated by services sector and incremental changes to existing businesses • Low development costs • Investment usually for revenue growth • Less than 5 years for acceptable ROI • Satisfying unmet market needs (existing markets) • Returns through M&A’s or IPO’s • Not universally applicable

  24. Years Since Commercial Introduction Market Penetration (Per Cent Households) Time to Max. TV – 30 yrs Color TV – 10 yrs Electricity – 75 yrs Automobile – 80 yrs Telephone – 90 yrs Cell phone – 20 yrs PC – 20 yrs Internet – 15 yrs

  25. Fuel Cell vs. Service Sector Commercialization • Some Fuel Cells are here today • Battery replacement • Military • Space Shuttle • Back-up power But, to impact domestic energy consumption: • FC’s require • 10-100X development funding $100-200 million per product (from now) – 10X development time (20 yrs) But, FC’s offer similar market opportunities ($20 billion) to service sector businesses

  26. Fuel Cell Commercialization Cost Comparison Fuel Cells Log [$] Service Sector Log [yrs]

  27. Service Sector vs. Fuel Cell Commercialization 2000 Service Fuel Cells DCF ( million $) 0 10 20 Yrs from 2006 -200 • Differentiators • Infrastructure • Capital intensity • Market Creation • Diversity • Competitive Alternatives

  28. Fuel Cell Cost Pyramid (DOE) Cost Contribution $/kW Industrial Segments Now Future Balance of Plant Packaging,Air/Fuel Handling 46 6% 44 12% Controls/Power Electronics Inverter, DC Boost,Sensors, Actuators 128 19% 110 28% 27% Hot Box Reformer, Recuperator Manifold, Filter, enclosure/insulation 184 109 28% Stack 325 48% 118 30% 683 382

  29. Fuel Cell Business Creation Gap • This time around----20-year development cycle (profitable industry following silicon chip history) • Suppliers betting on system integrators • System integrators require large infusions of capital to advance to product stage…the bottleneck in the cycle...returns are still beyond the horizon. • Gap: Financing development for an uncertain market.

  30. Years Since Commercial Introduction Fuel Cells? 2005-2060

  31. FC’s Early Adopter Chasm (Created by Government Development Programs) • Early demand for components • OEM’s commercial development • lags demonstration gov programs • Transition to commercial prototypes • Renewed demand as OEM’s • book product sales Revenue Chasm DCF [$] Years

  32. How does a fuel cell business survive and thrive? • Military “bootstrap” • Federal agency funding • Private investors • Strategic partners/customers • Leveraging Resources

  33. Building an Industry General Requirements • Source(s) of ideas • Availability of funds • Accessible Workforce • Education and Training Resources • Informed and supportive infrastructure • Competitive business environment • Regulations, Taxation, Financing etc.

  34. Critical Role for Building a Fuel Cell Industry in Ohio • Educate Policymakers • Create realistic expectations • Facilitate information exchange • Inform the public • Engage all interests • Create opportunities • Focus on government-University-Industry Relationships • Maintain an independent perspective • Enable new and existing companies to access resources to pursue fuel cell business plans more aggressively in Ohio than anywhere else
