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

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

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
