Hydrail

From Wikipedia, the free encyclopedia

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 like 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 key element of the proposed hydrogen economy. The term is now used extensively by research scholars and technicians around the world.[1][2][3][4][5][6][7] However, no hydrail rail systems are currently in public use.

Hydrail vehicles are usually hybrid vehicles and also have renewable energy storage solutions like batteries or super capacitors, for regenerative braking, which improves efficiency and lowers the amount of hydrogen storage required. Potential hydrail applications include all types of rail transport, like 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 Conference[edit]

Each year Appalachian State University and others organize an International Hydrail Conference, bringing together the scientists working on the technology around the world in order to expedite deployment of the technology for environmental, climate and energy security reasons. In 2010, the Sixth International Hydrail Conference was hosted in Istanbul, Turkey, by the United Nations Industrial Development Organization and the Turkish State Railways. Previous International Hydrail Conferences have been held in Herning, Denmark; Valencia, Spain; Charlotte, North Carolina; and Salisbury, North Carolina. 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). At this writing, the 2011 Hydrail Conference is scheduled to be convened in Seoul, South Korea, hosted by the Korean Railway Research Institute. The United States Environmental Protection Agency has co-sponsored all three of the International Hydrail Conferences held in the USA.

Coining[edit]

The term hydrail was coined on April 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.[8]

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 trolley arms and overhead track electrification, reducing construction cost, visual pollution and maintenance expense. The term 'hydrolley' is preferred to 'hydrail light rail' or other combinations because of their connotation of external electrification.

History, projects and prototypes[edit]

  • In 2009, BNSF unveiled the first hydrail locomotive, powered by hydrogen fuel cells.[14]
  • In 2010, a 357-kilometre (222 mi) high-speed hydrail line was proposed in Indonesia. The rail link, now under feasibility study, would connect several cities in Java with a hydrogen-powered maglev system.[15][16]
  • In November 2010, China demonstrated their first hydrail prototype.[17]
