Storing Green Energy To Last Germany 10 Days Would Require A 60-Million Tonne Battery

An article at the European Institute for Climate & Energy (EIKE) website here takes a critical look at whether battery parks would be feasible to fully secure Germany’s weather-dependent power generation from wind and solar.

Germany currently has a battery capacity of approximately 26 gigawatt-hours (GWh), the majority of which (approx. 20 GWh) consists of private home storage systems.
Only large-scale storage systems (approx. 4.3 GWh) are considered truly “grid-serving.” Currently, these could cover only about 5% of summer electricity demand for 1.5 hours.
The “Germany battery”: What would be required?
Energy expert Staffan Reveman presented a plausibility calculation for making Germany self-sufficient (without fossil fuel plants or imports). The results are sobering.
