Abstract: The study aims to provide the minimum cost for hydrogen infrastructure deployment. This is done by taking into account different hydrogen transportation modes including pipelines and trucks, and different hydrogen states as compressed gas, liquefied or chemically bound to a liquid carrier. As primary results, the minimum cost of transporting hydrogen via compressed gas trucks (CGT) is calculated. The levelized cost of transporting hydrogen (LCOTH) associated with, includes the transportation, the compression and storage as well. As the current market offers a variety of CGT at different compression rates, five different pressure levels are taken for the optimization problem to identify the corresponding capacities transported by each of them (at 165.5 bar, 250 bar, 350 bar, 500 bar and 540 bar). The capacities, associated with the five compression rates, giving the minimum cost are found out to not be unique and one example of the share of CGT at 540 bar is presented. About the minimum cost, the minimum LCOTH is between 2 €/kg and 2.7 €/kg at low flow rates below 0.5 ton per day (TPD), and decreases till 0.5 €/kg at flow rates beyond 5 TPD. The cost is doubled when transported over a distance of 300 km. Moreover, because the driver working hours are taken limited, LCOHT is peaking with more than 0.6 €/kg around 400 km. For the share of the different compression rates capacities, low CGT are used at low flow rates below 2 TPD, and higher CGT are needed when the capacity increases. The distance over which the hydrogen is transported plays a key role on increasing the number of CGT at 540 bar.
