Hydrogen Station and Fleet Demonstration at Penn State

Joel R. Anstrom, Pennsylvania State University

The principal objective of a recent cost-shared project between Air Products and Chemicals Inc. (Air Products) and the U.S. DOE was to develop and demonstrate commercial cost viability for a stand-alone, comprehensive hydrogen fueling station that can competitively deliver a hydrogen product stream meeting strict end-use performance requirements in the emerging hydrogen-for-transportation markets.  The first commercial unit of this station was installed at the University Park Campus of Penn State in 2005. The station is designed to push the envelope of current technologies in the areas of methane steam reforming, dispensing, and hydrogen pressure swing-adsorption purification.  The station is operational with hydrogen supplied from the natural gas reformer with backup supply from a liquid hydrogen storage tank. 
Through a partnership with the Penn State Office of Physical Plant (OPP), the Centre Area Transit Authority (CATA), and Collier Technologies, a fleet of hydrogen fueled vehicles was developed at Penn State’s Pennsylvania Transportation Institute (PTI) to place a significant hydrogen demand on the methane reformer of the new APCI hydrogen station.   Funding for fleet development and demonstration was provided by the Pennsylvania Department of Environmental Protection (PDEP) and the Department of Community and Economic Development (DCED).  PTI developed a hydrogen fuel cell vehicle from a production electric vehicle platform. Collier Technologies modified CNG engines to operate on a blend of 30% hydrogen and 70% natural gas (HCNG) for a CATA 40-ft transit bus and an OPP work van.  These first three vehicles are currently in service.  Additional funding form PDEP and DCED is allowing conversion and demonstration of six additional HCNG vans and a hydrogen powered hybrid vehicle, raising the fleet hydrogen demand near 40 kg per day.  This presentation will provide the startup experiences, operational history, and current status of the hydrogen station and vehicle fleet demonstration.
