petroleum consumption goes toward fueling vehicles, according to the U.S.

General sessions offered throughout the symposium's two days will include "The Challenges Facing Fuel Cells for Portable Consumer Products," "High-temperature Carbonate Fuel Cells in Commercial and Industrial Applications," "Generating and Managing Fuel Cell Test Data to Shorten R&D Cycles," "Advancements in Fuel Cell Catalysts and MEAs," "Low-cost Hydrogen Production Through PEM Electrolysis for Fueling Vehicles," "Hand-held Solid Oxide Fuel Cell System Development," "Fuel Cell Locomotives for Commercial and Military Railways" and "Alkaline Fuel Cells: Technology for the 21st Century."

"Sandy" Thomas, president of Virginia-based H2Gen, is that the capital costs of a national hydrogen fueling infrastructure based on miniature natural gas reformers will be less than that of sustaining the existing gasoline fueling structure.
