In comparison to 2021, the market for home storage systems (HSS) grew by 52% in terms of battery energy in 2022 and is by far the largest stationary storage market in
Why should Germany use energy storage systems?
Germany is under increasing pressure to rapidly decarbonize its electricity system, while ensuring a secure and affordable electricity supply. In this context, energy storage systems (ESSs) can play a crucial role in enabling a high share of variable renewable electricity generation.
How big is the home storage market in Germany in 2022?
In comparison to 2021, the market for home storage systems (HSS) grew by 52% in terms of battery energy in 2022 and is by far the largest stationary storage market in Germany. We estimate that about 220,000 HSS (1.9 GWh / 1.2 GW) were installed solely in 2022.
Should Germany invest in ESSs after 2036?
Overall, the study highlights the necessity to invest in ESSs, especially after 2036 when aiming for a cost-optimal and renewable electricity system transition in Germany. Especially the deployment of hydrogen storage can play a decisive role in the transition.
Can pumped hydro storage be a key component of Germany's electricity system?
The study by Keles and Yilmaz , for instance, considers only the option of pumped hydro storage (PHS), as it is already a key component of the German electricity system. Others consider multiple technology options, with Bartholdsen et al. , for instance, considering also lithium-ion batteries and hydrogen storage (via power-to-gas).
How is Germany transforming the energy system?
In addition to the complexity of transforming the German electricity system, climate-related targets and policies have been tightened substantially. The newest amendment of the Renewable Energy Sources law requires renewable energy sources to cover at least 80% of the annual electricity consumption in 2030.
How many industrial storage systems were installed in 2022?
We estimate that about 220,000 HSS (1.9 GWh / 1.2 GW) were installed solely in 2022. The emerging market for industrial storage systems (ISS) grew by 24% in 2022, with a total of 1,200 ISS (0.08 GWh / 0.04 GW) installed. The market for large-scale storage systems (LSS) increased strongly by 910% with 47 LSS (0.47 GWh / 0.43 GW) commissioned.
