The Hydrogen Bus Technology Validation Program
The Hydrogen Bus Technology Validation Program (Davis/Sacramento, California) is a multi-district partnership of the City of Davis, Yolo County Transportation District (YCTD), University of California, Davis (UC Davis), UniTrans (transit authority for the City of Davis and UC Davis), and Collier Technologies, Inc. The purpose of the program is to validate advanced clean fuel technologies in a practical application, thereby reducing emissions by reducing reliance on polluting and toxic diesel fuel. In particular, hydrogen-enriched natural gas buses are a promising technology for two reasons. First, they are expected to meet the California Air Resources Board’s strict transit emissions requirements. Second, they require development of a hydrogen infrastructure that can pave the way to use of fuel cells, widely considered the future of transportation technology.

Collier Technologies, Inc.’s role is to provide conversion of the existing CNG engine to operate on HCNG in an ultra-lean burn mode to reduce controlled exhaust emissions while maintaining engine power output. The purpose of the program is to validate clean, advanced hydrogen fuel technologies in a transit bus application.
