100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

Air Products 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.

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.
