Hydrogen is one of the highly used gas as it has a wide range of use from fertilizer production to fuel-cell vehicles. Therefore, cross-border export of hydrogen is a promising future in the field of the green energy market. Gaseous hydrogen can be transported through pipelines much the way natural gas is today. Approximately 1,600 miles of hydrogen pipelines are currently operating in the United States. And hydrogen transportation using ship cargos can also be taken as an alternative to pipelines which seems less feasible economically in fact a pipeline network would be the best option for the comprehensive and largescale use of hydrogen as an energy source. However, pipelines require high levels of initial investment, which may pay off, but only with correspondingly large volumes of hydrogen. Nevertheless, one possibility for developing pipeline networks for hydrogen distribution is local or regional networks, known as micro-networks. These could subsequently be combined into transregional networks.
