"Gallon Equivalent"
means either a gallon diesel equivalent or a gallon gasoline equivalent.
"Hydrogen"
means a hydrogen fuel composed of molecular hydrogen intended for consumption in a surface vehicle or mobile electricity production device with an internal combustion engine or fuel cell and includes liquid and gaseous hydrogen.
"Hydrogen system"
means a system of safety devices, cylinders, piping, fittings, valves, compressors, regulators, gauges, relief devices, vents, installation fixtures, and other hydrogen equipment intended for use or used in any building or commercial installation, or used in conjunction with a motor vehicle or mobile fuel system fueled by hydrogen, or any system or facilities designed to be used or used in the sale, storage, transportation for delivery, or distribution of hydrogen in portable hydrogen cylinders, not including hydrogen facilities, equipment, or pipelines located upstream of the inlet of a hydrogen fill station.
