The effects of electricity tariffs on cost-minimal hydrogen supply chains and their impact on electricity prices and redispatch costs

Hydrogen fueled transportation can contribute substantially to the reduction of global carbon emissions. However, production hydrogen through electrolysis creates interdependencies with electricity systems. Therefore, we present a new model which couples supply chain system. We use this analyse case study Germany in 2030. find that if efficient spatially resolved tariffs are applied instead existing uniform tariffs, electrolyzers placed primarily at low-cost nodes and farther away from consumption centers. For hydrogen, leads higher costs, but lower total costs. Moreover, costs for congestion management decrease substantially.
