@ -56,6 +56,8 @@ incorporates retrofitting options to hydrogen.
**New features and functionality**
* Units are assigned to the buses. These only provide a better understanding. The specifications of the units are not taken into account in the optimisation, which means that no automatic conversion of units takes place.
* Option ``retrieve_sector_databundle`` to automatically retrieve and extract data bundle.
* Add regionalised hydrogen salt cavern storage potentials from `Technical Potential of Salt Caverns for Hydrogen Storage in Europe <https://doi.org/10.20944/preprints201910.0187.v1>`_.
