News ReleaseAir Products’ Hydrogen Technology Fueling AC Transit’s Next Generation Bus Fleet

December 21, 2010 Lehigh Valley, Pa.

Air Products (NYSE: APD) is using its diverse portfolio of hydrogen fueling technologies to fill five new hydrogen fuel cell powered buses that transport riders daily on the Alameda-Contra Costa Transit District (AC Transit) bus system in the San Francisco Bay Area in California. AC Transit looked to Air Products for solutions to provide hydrogen and infrastructure technology to get the newest generation of zero emission buses on the road quickly. AC Transit expects to increase its hydrogen fuel cell bus fleet to 12—the largest single site deployment of hydrogen fuel cell buses in the United States.

“AC Transit should be very proud of its growing hydrogen bus fleet and being a leader in the U.S. in the conversion to this zero emission mode of mass transit transportation. We’re pleased to be fueling their buses and bringing several of our patented fueling technologies together to support this large scale fueling application,” said Nick Mittica, commercial manager–Hydrogen Energy Systems at Air Products. “At this site, we’ve been able to show our broad suite of unique hydrogen delivery technologies that no one else in the world has to offer. These capabilities give us a competitive advantage when considering varied hydrogen sources as well as the methods of hydrogen delivery.” Mittica added that the Air Products technologies in place at AC Transit were relatively easy to permit and presented no large infrastructure issues.

“Air Products has clearly demonstrated to us and our industry that the technology and know-how exists to effectively fuel heavy-duty transit buses on a large scale. We’ve been impressed at how quickly the Air Products team stepped up to support our fueling needs by installing a 500 kg mobile fueling station within days,” noted Jaimie Levin, AC Transit’s director of Alternative Fuels Policy and Hydrogen Fuel Cell Program manager.

Air Products has two of its self-contained mobile fuelers and additional high-pressure storage capacity, all at approximately 350 bar (5,000 psi), at AC Transit’s Oakland, Calif. operating division. The station employs a new hydrogen delivery concept capable of dispensing either liquid or gaseous hydrogen, at very high pressure, depending on a specific customer’s need. The mobile fueling technology is able to dispense hydrogen to the buses without the need for a utility hook-up as solar panels on the top of the fuelers provide the electrical power for the dispensing unit. In all, Air Products has 20 mobile fuelers and six new delivery liquid trailers at locations in the U.S. and Europe. Details on Air Products’ hydrogen fueling station technologies are at

The hydrogen powered fuel cell bus fleet is part of an AC Transit demonstration project called Zero Emission Bay Area (ZEBA) using the next generation of fuel cell buses in its mass transit system. The new buses are 5,000 pounds lighter and shorter in height than the earlier generation of fuel cell buses and feature the newest fuel cell power and energy storage systems.

This project is the latest in several hydrogen-fueled mass transit announcements by Air Products. In December, Air Products announced the commissioning of its fueling station in London, filling a fleet of five hydrogen buses as part of the Transport for London Project. In addition, the first fleet of London hydrogen taxis is planned for 2012, to contribute further to the hydrogen infrastructure and to reduce emissions in London. In November, Air Products provided the hydrogen to fuel a fleet of more than 50 hydrogen fuel cell shuttle vehicles that transported athletes and government officials at the Asian Games and Asian Para Games in Guangzhou City, China. This project was similar to Air Products’ filling hydrogen buses at a fueling station in the Beijing Hydrogen Park during the 2008 Beijing Olympic Games, which marked the first demonstration project for new-energy vehicles in China.

Air Products, the leading hydrogen supplier to refineries to assist in making cleaner burning transportation fuels, has unique experience in the hydrogen fueling industry. These varied fueling applications provide an opportunity to assess consumer experiences, evaluate product performance and advance product improvements. In fact, in certain market applications, fueling rates at several individual sites of over 10,000 refills per year are occurring. The company has placed over 120 hydrogen fueling stations in the United States and 18 countries worldwide. Cars, trucks, vans, buses, scooters, forklifts, locomotives, planes, cell towers, material handling equipment, and even submarines have been fueled with trend-setting technologies that involve Air Products’ know-how, equipment and hydrogen. Use of the company’s technology is increasing and is currently over 225,000 hydrogen fills per year.

Air Products has more than 50 years of hydrogen experience and is on the forefront of hydrogen energy technology development. Air Products has an extensive patent portfolio with over 50 patents in hydrogen dispensing technology. Air Products provides liquid and gaseous hydrogen, and HCNG (hydrogen/compressed natural gas) fueling, and has developed a variety of enabling devices and protocols for fuel dispensing at varied pressures. Hydrogen for these stations can be delivered to a site via truck, produced by natural gas reformation, biomass conversion, or by electrolysis, including electrolysis that is solar and wind driven.
