Weltweite Infrastruktur zur Wasserstoffbereitstellung auf Basis erneuerbarer Energien
International climate protection goals, shrinking fossil energy reserves and a growing globalenergy demand require the massive integration of renewable energy sources into the globalenergy system. The utilization of large wind and solar energy resources in international, climaticallyand geographically favorable regions in order to supply regions worldwide with highenergyrequirements poses the challenge of spatial and temporal discrepancies between energysupply and demand. The use of hydrogen based on renewable energies offers a promisingoption for meeting this challenge.The objective of this work is the conception and techno-economic evaluation of a worldwidehydrogen infrastructure based on renewable energies to cover a future global hydrogen demand.In this context, it is necessary to calculate the worldwide supply potential of renewablyproduced hydrogen, to identify the significant cost contributions within the framework of theinfrastructure and to determine cost-optimal import pathways. The analysis stands out due atemporally and spatially resolved modeling of the electricity generation from wind and solarenergy as well as the domestic supply infrastructure for hydrogen. Subject to defined degreesof expansion of the renewable energy technologies, supply and cost curves for hydrogen result,providing the basis for the hydrogen allocation with the aim of minimizing global overallcost.The determined hydrogen supply potential of 1,590 MtH2 in the investigated preferential regionsclearly exceeds the projected global demand range of 244 to 487 MtH2 in 2050. More than 75%of the hydrogen potential in the preferential regions can be provided for costs below4.00 EUR/kgH2. The resulting import costs are affected only to a minor extent by supply anddemand variations and range between 3.00 and 4.50 EUR/kgH2 depending on the import region.From an economic point of view, cost optimal wind energy expansion levels for hydrogen exportshould be aimed for in all selected strong wind regions. At the same time, a massiveexpansion of ...
