AC Transit opens innovative hydrogen fueling facility

Submitted By AC Transit

AC Transit and a coalition of regional transit partners, serving 7 million people in the Bay Area, presented 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 on April 10, 2012 at AC Transit's Emeryville division where hydrogen to fuel the fleet is produced in part by solar-powered electrolysis.

"For more than 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," said AC Transit General Manager David Armijo.

AC Transit's 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 5 kilograms per minute - a time comparable to refueling diesel buses. Thanks to a major grant from the California Air Resources Board, one dispenser is accessible to the public for fueling hydrogen fuel cell electric passenger cars, including the Mercedes-Benz B-Class F-CELL, now on the road in both Northern and Southern California.

"Linde is excited to provide a clean fuel solution that delivers so many quality-of-life benefits to Bay Area residents. Their public transportation will now be quieter, the air fresher and cleaner and we're using a domestically produced fuel instead of imported oil. These are positive, concrete steps toward reducing greenhouse gases and increasing sustainability. Linde is proud to take such a prominent role in improving our future," said Pat Murphy, President, Linde North America.

Fuel cells do not burn the fuel they use. Instead, they combine hydrogen with oxygen from the air electrochemically to produce electricity and emit only water vapor. AC Transit operates a dozen 40' hybrid-electric, zero-emission fuel cell buses, each powered by a 120 kW UTC Power fuel cell system and a Siemens ELFA Drive System.

"We are proud to partner with AC Transit," said Joe Triompo, VP and General Manager, UTC Power. "Their leadership in the deployment of fuel cell buses in the United States and their commitment to reducing their environmental impact are inspiring. We believe the future of energy is here and embodied in the fuel cell buses operated by AC Transit. With multiple fuel cell buses in operation today, AC Transit and the community the agency serves are already reaping the benefits of superior efficiency, increased reliability and reduced emissions for environmentally responsible operations."

In recognition of AC Transit's solar installations across its facilities, Pacific Gas and Electric Company (PG&E) presented a check, representing what will amount to more than $500,000 in rebate incentives from PG&E through the California Solar Initiative (CSI) program, to AC Transit's General Manager. Additionally, in honor of AC Transit's HyRoad Program, Tom Sullivan, Chairman of Proton OnSite, presented a $20,000 check to Lawrence Hall of Science at UC Berkeley to further youth science education in alternative fuels.
