In the StEAM project, the extent to which the interrelationships of a global energy system influence the global production and distribution of hydrogen will be investigated in depth. For this purpose, a global energy system model is to be developed based on an existing open-source model and an existing global electricity system dataset, which represents both the electricity sector and a global hydrogen economy including its transport infrastructure as well as the use and transport of other gaseous energy carriers. The developed model should allow the assessment of the embedding of the German hydrogen strategy in the international context on the basis of consistent future scenarios. By means of an application study, an estimation of the economic effects of different design measures of the hydrogen economy in different modeled futures is made. By using methods of "Modeling to Generate Alternatives", the possibility of different, heterogeneous hydrogen transformation paths will be examined.
