A new technologically advanced bus with zero emissions is about to hit the streets of Austin. The Hydrogen Hybrid Bus will go into service this month among the University of Texas shuttles, alternating between the Forty Acres and Intramural Fields routes.
Capital Metro along with the University of Texas Center for Electromechanics (UT-CEM) and several other local and national partners have a unique opportunity to be a part of an important project by studying and further refining fuel cell technology.
During the yearlong demonstration, the bus will be fueled at UT-CEM’s state-of-the-art hydrogen fueling station located on the J.J. Pickle Research Campus. Thanks to support by Gas Technology Institute and the Texas Commission on Environmental Quality (TCEQ), this station allows for the generation, compression, storage and dispensing of hydrogen on-site.
The prototype bus, manufactured by Proterra, combines electric battery power and mobile hydrogen fuel cells. The bus is a zero emission vehicle; water is the only exhaust. It uses a large lithium battery pack along with an electric drive train and custom transmission. Two hydrogen fuel cells operate to keep the battery pack fully charged.
