Abstract: The lightest and most abundant element in the universe is hydrogen, and it is an energy carrier. It can be produced using different methods from multiple sources and shipped to the fuelling station, or it can even be produced at the fuelling station.Water electrolysis or reforming of hydrocarbons such as natural gas will produce hydrogen in a large plant or even at the fuelling station. But when generated using renewable energy, such as wind, solar, geothermal, or hydroelectric, it has zero emissions.Hydrogen-powered vehicles either burn hydrogen in an internal combustion engine, or in a fuel cell react with oxygen.The idea of hydrogen highway is essentially to build a chain of hydrogen-equipped fuelling stations and other facilities along the city road or highway that will enable hydrogen powered cars to drive.More extensive hydrogen delivery facilities would include the use of high-pressure compressors for gaseous hydrogen and cryogenic hydrogen liquefaction systems.Hydrogen can be generated on site, transported by road via cylinders, cryogenic tankers, tube trailers, and in pipeline. Each of these modes of delivery and production requires a considerably different design of the fuelling station.Proton exchange membrane fuel cells (PEMFCs) can be considered as they are electrochemical devices that can produce electricity directly from hydrogen and oxygen without combustion, making the process clean and non-polluting.
