AC Transit, and a coalition of regional transit partners serving seven million people in the Bay Area, have unveiled the newest hydrogen production and dispensing station to fuel the latest generation of zero-emission fuel 
cell buses operating in AC Transit’s service area. Federal, state, and local officials formally dedicated the station at AC Transit’s Emeryville division, where hydrogen to fuel the fleet is produced in part by solar-powered electrolysis.
AC Transit General Manager David Armijo said: “For over a decade, AC Transit has been developing the most comprehensive, zero-emission, fuel cell transit program in North America, and operating zero-emission buses in real-world service. Now, with increased fueling capacity, we have a greater capability to offer clean, quiet, zero emission transportation to the communities we serve.”
AC Transit officials say the newest on-site energy station, engineered by Linde North America, Jacobs, and EPC, and built by W.L. Butler Construction, demonstrates the use of “renewable” hydrogen – hydrogen produced using Proton OnSite’s solar-powered electrolyzer. Engineering and construction firm Cupertino Electric, Inc. installed a 510 kilowatt DC solar photovoltaic system for AC Transit that will generate energy to help fuel the transit system’s hydrogen-powered buses running throughout the Bay Area.
The station also features Linde’s latest advancements in compression and dispensing technology, enabling buses to be refueled at rates up to five kilograms/minute – a time comparable to refueling diesel buses.
