ÖSpeicher2040 - Determination of storage requirements in the Austrian electricity system 2040

This study aims to determine the Austrian electricity system's short-, medium-, and long-term energy storage requirements in 2040. Austria's and European goals for decarbonizing our energy systems rely on increased electrification of, e.g., transport, heat, industrial processes, etc.. National energy policy goals, such as the planned expansion paths of the Renewable Energy Act (EAG), focus on the expansion of renewable energy sources (wind, PV, water, biomass) but do not quantify the performance or energy-related capacities of storage technologies (in addition to those installed to date) that would be necessary to achieve complete climate neutrality of the Austrian electricity system. The following research questions should be answered: How much energy storage capacity (both installed capacity and energy quantities) would be necessary for Austria (Power to X to Power) to achieve the climate targets by 2040? How many short-, medium- and long-term storage technologies are involved, and how are they optimally operated? How do these capacities change assuming up to 3 different scenarios (e.g., with different weather years)?
