The ZETBTA is a robust side-by-side evaluation of the predominant engine technologies in use at transit agencies worldwide: fuel-cell electric bus (FCEB), battery electric bus (BEB), diesel hybrid, and conventional diesel bus propulsion systems.
“AC Transit currently operates all five propulsion technologies and is uniquely positioned to support this rigorous study,” says General Manager Michael Hursh. “For Long Range Planners, this is an unrivaled collection of years of research, transit planning, and design; made stronger because the propulsion metrics are not cobbled from several sources but instead one agency, with roadway testing on the same routes, and in the same service environment.”
The study launched in July 2020 and integrated lessons learned and best practices gleaned from our extensive experience deploying ZEB technologies, including the development of innovative workforce training programs, data integration and management, and transit deployment viability.
This initial iteration of the ZETBTA will help transit agency leaders understand step-by-step the capital cost, performance, and operating cost between ZEB types when comparing performance to conventional diesel bus technologies. The study is also a collection of energy data to develop metrics for costs, mileage, reliability, and availability.
