Background • Price of fuel for cars and light trucks is increasing • Increasing demand from developing populations • Declining discoveries of crude oil • Conflicts in oil producing regions • US consumer demand exceeds US supply • Reliance on exports • Energy security concern • Burning gasoline for transportation creates environmental problems, smog, CO2, etc.
Background • Global light vehicle ( cars and light trucks) production - 55 to 60 million/yr • Estimated 500 million light vehicles in use • 78% gasoline • 22% diesel • Growth of Ownership
Context: • In the U.S., we have: • - 2% of the World’s oil reserve; • - 8% of World oil production; • - 5% of the World population; • - we consume 25% of World’s production, and • - more than 2/3 of our consumption is imported. • Emerging economies increased demand are changing the “balance,” e.g. China, • - China has bought excess capacity of Canada, • - Almost bought Unocal; major commitments from Mideast. • In 2005 we launched one new submarine, • China launched 14 (albeit lower quality)…
Context: Cities with 10 million people • By 2020, more than 30 mega-cities in the now less-developed world. By 2050, nearly 60 such cities. • Increased population creates need for more resources. World's electricity supply will need to triple by 2050 to keep up with demand, necessitating nearly 10,000 GW of new generating capacity.

Issues facing US consumers • What fuel price would influence you to choose a new vehicle type? • Europe currently pays about $6/gal due to taxes • US is considering increasing gas tax • What vehicles will be available? • What fueling station infrastructure will be convenient?
Answering Consumer ChallengesAn Example: Galvin Electricity Initiative • Each day, roughly 500,000 Americans spend at least two hours without electricity (cost to our economy $150B/year). • The future looks even worse. Without substantial innovation and investment, rolling blackouts and soaring power bills will become a persistent fact of life in this country. • Mission: The Galvin Electricity Initiative is leading a campaign to create a perfect power system. A perfect power system cannot fail the consumer. It is environmentally sound and fuel-efficient. It is robust and resilient; able to withstand natural and weather-related disasters and mitigate the potential damage caused by terrorist attack. The perfect power system provides affordable electricity to all consumers and allows consumers to control their own energy use to the extent they choose. • History: The Galvin Electricity Initiative was officially launched in 2005, but its genesis dates back to the massive East Coast blackout of August 2003, which left nearly 50 million people without power and inspired former Motorola chief to take action.

Societal/Human Needs→ Technology → System What will be its needs for systems consuming energy (functionally)? What existing and emerging technologies can meet those needs? What power system implications do those solutions imply? How will society evolve? Are there entirely new pivotal technologies which could be potentially available? Killer Ap? Will those influence society? Are there applications of pivotal science and technology outside energy that may apply?
How do we figure out what may work? Consumer Needs Technology Potential Technology Scan • Identify societal attributes • How may society’s technology needs evolve (scenario)? • What will be the technology needs of those societies? • Identify dominant needs • Determine the potential of known (existing and emerging) technologies • Determine where clustersof applications exist • Scan the technology horizon broadly for innovation possibilities Nodes of Opportunity

Future Consumer Needs Relieve Congestion Reduce Energy Use Revitalize Cities Transportation Serve Diverse Communities Source: Galvin Electricity Initiative
Big 4 issues automakers face in meeting those needs • Energy diversity • Climate change • Population and Congestion • Air quality
Transportation Fuel Options that Meet These Challenges are Limited • Electricity (plugging into the grid): Requires “greening the grid” and solving storage/battery issues • Liquids from coal: Without CCS*, this would be worse than gasoline from a climate standpoint • Biofuels: UCS study on biofuels suggested that they could perhaps meet 30 to 50% of U.S. transportation fuel needs. We’ll still need that other 50%! • Hydrogen: Made from renewable and low-carbon sources * CCS: Carbon Capture and Sequestration

Vehicle & Fuel Evolution Already Underway Both GM and Toyota pursuing: • Hybrid ICEs • Plug-in ICEs • Plug-in hydrogen fuel cell electrics. Chevy Volt Ford Edge Honda FCX
Chevy Volt as example of vehicle trends • Fuel cell is simply used as a range-extender (not as a replacement for the ICE). • The fuel cell simply keeps the battery charged • Easier to put electric infrastructure in place than H2 infrastructure.
Do any hydrogen vehicles exist today? • Every major automaker has prototypes • 400-500 vehicles on the road • 38 Hybrid Priuses have been converted to run on hydrogen, most operating in 5 cities in LA basin • At least 10 types of H2 ICE vehicles deployed or being developed
When might you buy a fuel cell vehicle? • Automakers racing to be first; GM says by 2011 • Both Honda and BMW have announced plans to go to production BEFORE 2010 • Others think longer or never • First vehicles are fleets GM’s Sequel, 300 mile range GM putting 100 of these on the road in 2007
GM Targets for Deployment 2007 to 2010: 100 vehicles (10 stations) 2011 to 2013: 1000 vehicles (100 stations) 2014 to 2016: 10,000 vehicles (250 stations) Commercial deployment in mass market Chevy “Volt” plug-in hybrid
1st fuel cell family has completed first year Honda FCX4 Jon and Sandy Spallino and daughters, Redondo Beach, California
Are there any hydrogen stations today? • >100 stations worldwide • California has 23 stations; 15 more underway; 100 planned by 2010 • 1st public station in Washington DC • 170 new stations planned (VT, OH, CA, DC, FL, NV, NY, etc.) • CA, FL, NY, Canada, Japan and Norway have “H2 highway” projects H2 Highway in BC
How Soon? U.S. Goal: Fuel cell vehicles in the showroom and hydrogen at filling stations by 2020

“Electrifying America’s Transportation:A Value Proposition for Electric Drive Vehicles” A study by Professor James A. Weinbrake, James Madison University, 2002 Sponsored by EPRI’s Technology Roadmap Project • Assumes by 2025 • Half of all cars are Hybrids • Half of those are plug-in Hybrids • Based on DOE – EIA projections for energy use
Hybrid Electric Vehicle (HEV) Comparison Plug-in HEVs: • reduce emissions, energy use, CO2, and petroleum consumption more than power assist HEVs • yield greater benefits as range increases • All HEVs can be expected to cost more than CVs • Even at significantly higher capital costs, plug-in HEVs can succeed in the market
