Advanced development of hydrogen engines for diverse transportation

The hazard of conventional fossil fuels that transportation relies on nowadays has urged the scientific community to speed up the process of diminishing the pollutants caused by daily transportation and finding an opulent energy source for its superstition. Renewable resources and hydrogen are deemed as the next generation resource. However, hydrogen is the ultimate choice for transportation for its excellent performance both in the fields of environmental protection and energy. In this article, a study on the global production of hydrogen is performed, delving into the present conditions of the hydrogen industry. The principles referred to when choosing hydrogen to be an energy source for various transportation are discussed, and a comparison between conventional fuel engines and hydrogen fuel engines is made. The existing technical problems concerning the application of hydrogen engines or hydrogen fuel cells are reviewed. Combined with the usage of technologies on hydrogen, an envisage of future clean transportation is demonstrated.
