Özet:

Hydrogen is a transportation fuel that will play a major role in the transition toward a hydrogen-based energy system. When combined with the right source of energy, the hydrogen energy system has the highest potential efficiencies and lowest potential emissions of any transportation sector. The aim of this paper is to highlight some of the transportation technology research and development work from the past twenty years. These current efforts are divided into the improvement of several parts: motivity factor, versatility, utilization efficiency, safety and pollution reduction. Environmental and economic assessments of the entire hydrogen supply chain, including fuel cell end-use, are being carried out by researchers around the world. Analyses show that the hydrogen energy system will likely be both economically competitive and environmentally friendly. Indeed, the transition of the transportation sector to the use of hydrogen fuel will represent one of the biggest steps toward pollution reduction.
