The Future of Public Transport – In Pursuit of Zero Emissions Jaimie Levin
AC Transit • Serving1.5 million peoplein 13 cities • 67 million passengers • 650 buses • 2,190 employees • $309 million budget • 105 lines (27 transbay)
Addicted to Oil* • Less than 5% of Population Consumes 25% of World Oil • 25% to 30% of World’s Carbon Emissions • Import 60% of The Oil We Consume • 67% Consumed by Transportation • [Sources: * George Bush/ Data: U.S. DOE; Energy Information Agency]

Getting Started with Hydrogen • ZEbus Test – November 1999 • NeBus Test – 2000 • California Fuel Cell Partnership – 2000 • ISE/UTC Thor Bus – 2003/2004
What’s A Fuel Cell? • An electrical generator • NOT a battery • A chemical reaction between hydrogen and oxygen • Emits only water vapor and heat • 120 kW to 200 kW of output
What Motivates Us? • Public Health: urban centers/people at risk • Quality of Life: quiet buses • Cost Savings: Reduced life cycle costs Hydrogen’s Potential Value – • Sustainability: Diversified and RenewableEnergy Supply • Energy Independence (National Security) • Reduction inGlobal Warming
Why Transit? • The Real World vs. Super Computer Unlimited Variables • Government as Early Adopter and Change Agent (R&D; Tech Validation) • Centralized Fueling and Maintenance • Professionally Trained Staff • Public Exposure • Energy Benefits of Using Transit
Our Customers • 200,000 Passengers • 500,000 @ Events • Clean • Quiet • Smooth
18 Line UC Campus 2.5 mile grade at approximately 5% Berkeley Albany Oakland
Emissions Reduction – 3 Buses • 316Tons of CO2 (40% – 50% Net Reduction, Well-to-Wheel) • 3,330Pounds of NOx • 40 Pounds of Particulates • 21,000 gallons of diesel saved
Next-Generation Design – 2009 • Several Thousands Pounds Lighter • Better Energy Storage • Lower profile • 55 mph • 12% Grade • 8 to 12 Buses • $2.2 Million
