Hydrail

Hydrail is the generic term denoting all forms of rail vehicles, large or small, which use on-board hydrogen as a source of energy to power the traction motors, or the auxiliaries, or both. Hydrail vehicles convert the chemical energy of hydrogen to mechanical energy, either by burning hydrogen in a hydrogen internal combustion engine vehicle, or by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling rail transportation is a basic element of the proposed hydrogen economy. The term is used extensively by research scholars and technicians around the world.

Hydrail vehicles are usually hybrid vehicles with renewable energy storage, such as batteries or super capacitors, for regenerative braking, improving efficiency and lowering the amount of hydrogen storage required. Potential hydrail applications include all types of rail transport: commuter rail; passenger rail; freight rail; light rail; rail rapid transit; mine railways; industrial railway systems; trams; and special rail rides at parks and museums.

International Hydrail Conferences

Each year Appalachian State University and others organize an International Hydrail Conference, bringing together scientists, engineers and industrial experts working on the technology around the world in order to expedite deployment of the technology for environmental, climate, energy security and economic development reasons. Previous conferences have been held in Herning, Denmark; Valencia, Spain; Charlotte, North Carolina, Salisbury, North Carolina, Istanbul, Turkey, University of Birmingham, UK, Toronto, Canada and Neumünster, Germany. Presenters at these conferences have included national and state/provincial agencies from the USA, Canada, Denmark, Italy, Japan, Korea, Russia, Turkey, the United Kingdom, the European Union and the United Nations (UNIDO-ICHET).

History

The term hydrail was coined on February 17, 2004 in the International Journal of Hydrogen Energy as a search engine target word to enable scholars and technicians around the world working in the hydrogen rail area to more easily publish and locate all work done in the discipline.

Hydrolley

A hydrolley is a streetcar or tram (trolley) using hydrail technology. The term (for hydrogen trolley) was coined at the Fourth International Hydrail Conference, Valencia, Spain, in 2008, as a research-simplifying search engine target word. Onboard hydrogen-derived power eliminates the need for overhead trolley arms and track electrification, greatly reducing construction cost, reducing visual pollution and eliminating the maintenance expense of track electrification. The term 'hydrolley' is preferred to 'hydrail light rail' or other combinations which might connote external electrification.

Projects and prototypes
