1. Preparation of input data

The storage of hydrogen in salt caverns is the most promising technology option. Only the north of Germany has the geological potential to store hydrogen in salt caverns. Therefore, you can find three hydrogen cavern storages in the northern nodes DE0 3, DE0 4 and DE0 6. They are pre-implemented with a maximal storage capacities of 7.73 PWh each [1]. To produce hydrogen from electricity, we will use electrolyses, to retransform the hydrogen to electricity, we will use hydrogen gas turbines. The implementation of hydrogen storages is very similar to the implementation of battery storages.
