Abstract

With the increasing expansion of renewable energies in Germany, the temporary electricity surplus is rising and with it the need for large-scale energy storage. In this research, a systematic comparison of different concepts for large-scale storage of electrical energy is carried out based on technical and economic parameters. The investigated concepts include a diabatic compressed air energy storage power plant (CAES), an adiabatic compressed air energy storage power plant (ACAES), a hydrogen compressed air energy storage power plant (HCAES) as well as a hydrogen energy storage power plant with a gas turbine (HES-GT) and a hydrogen storage power plant with a fuel cell (HES-FC).

The round-trip efficiency and the storage capacity of each storage power plant concept are determined using simplified thermodynamic correlations. The charging capacities range between 3.9 GWh (CAES) and 81.8 GWh (HES) with round-trip efficiencies from 28% (HES-GT) to 69% (ACAES). The technology readiness level is estimated between 8 (CAES) and 4 (ACAES). The investment costs of each component are determined with cost functions based on thermodynamic parameters and an extensive literature review. The analysis additionally includes the ability to provide ancillary services, greenhouse gas emissions, storage losses and demand of land. Results show that the hydrogen compressed air energy storage (HCAES) is the best storage option when all criteria are weighted equally. CAES is not suitable for a renewable energy system due to carbon emissions and ACAES and HES-FC both have a low TRL and high investment costs. However, all energy storage concepts have different advantages and development potential and the suitability of any concept depends on the use case.
