Hydrogen as the best choice for fuel

Sustainable development requires a supply of energy resources that is sustainable , available at reasonable cost and causes no or minimal negative effects . Fossil energy resources are finite , and thus lack the characteristics needed for stability and sustainability , while green energy sources are sustainable over the relatively long term (Dincer Rosen , 2004 . Particularly , cost effective and environmentally benign green energy is the most essential means for increasing the sustainable technological development and industrial productivity as well as people 's living standard in a society . Therefore

, permanent and effective hydrogen energy strategies should be put forward to increase the use and application of hydrogen from non-fossil fuel sources and green energy based hydrogen technologies (Midilli et al , 2005 . Hydrogen has been widely considered as a potentially viable alternative to fossil fuels for use in transportation . In addition to price competitiveness with fossil fuels , a key to its adoption will be public perceptions of hydrogen technologies and hydrogen fuel (Hickson et al , 2007

According to Dunn (2002 ) three factors have driven the development of alternative fuels for use in transportation . These are reducing the undesirable effects of greenhouse gases on climate , decreasing dependence on fossil fuels , thereby increasing energy security , and reducing local air pollution . Efforts to develop alternative fuels have primarily focused on bio-fuels , such as methanol , ethanol and bio-diesel and the advancement of hydrogen technologies . At the fuel production stage , both bio-fuels and hydrogen can be developed from renewable sources , the former through the refinement of products such as grains and oilseeds , and the latter through harnessing wind energy for electrolysis . While both groups of fuels provide for a reduction in greenhouse gas emissions , hydrogen is often considered the gold standard as the sole by-products of combustion are water and nitrogen oxides

Current energy chains deplete non-renewable resources and release harmful pollutants , producing waste and both local and global pollution A wider and long lasting development can exist only through realization of energy cycles using renewable energy sources and to achieve no impact on environment . Hydrogen is the simplest and most diffused chemical element , obtainable in many ways , with an efficient and clean use , and high calorific value represents the best storable energy vector to realize a global closed cycle of energy resources (CCER (Orecchini and Bocci , 2007

Hydrogen can be produced by using fossil fuels such as oil , coal and natural gas or renewable energy sources as water . Hydrogen in high purity can be produced through the electrolysis of water . The required electrical power can be supplied by renewable energy resources such as solar , wind , wave , tide or hydraulics (Kahraman et al , 2006

Price competitiveness depends on the relative costs of hydrogen bio-fuels and fossil fuel alternatives . The cost of producing hydrogen varies significantly by the type of technology and distribution channel The United States National Research Council and National Academy of Engineering (2004 ) found that for hydrogen made onsite from electrolysis . Given that future cost paths of these technologies are largely unknown...
