11/08/01 13 SAFE TEA Initiative: Fuel Cell Bus Technology Program Fuel cells can be long-term solution to air quality, energy security and global warming problems Significant potential public benefits justify federal investment Fuel cells aren’t ready for prime time Technical issues: reliability, life-cycle, start-up time, weight, volume, etc. Cost challenges: fuel cells buses costs need to decline by more factor of more than 10X Federal investment will speed development of the technology and encourage development of U.S. industry

11/08/01 14 Fuel Cell Bus Technology Program Objectives Provide funding for development of key fuel cell technologies (fuel cells, H2 storage, reformers, power electronics, electric drive trains, batteries, etc.) Vibrant fuel cell bus demonstration programs with transit districts (will focus on 5-7 key properties) Support development of cost-effective refueling stations and technologies Develop and test reformers using renewable fuels Seek matching funds to maximize benefit of program Increase public awareness and acceptance

11/08/01 15 Transit Buses – Best Way to Introduce New Fuel Transit buses operate on fixed routes and return to centralized refueling location so refueling is not an issue Buses have fewer packaging and weight constraints than passenger cars Transit districts have highly skilled mechanics who provide regular service and maintenance Subsidized purchasing system Buses are mobile classrooms and billboards
