Germany Faces Impractical Battery-Only Grid Backup
|
5.7
A plausibility study published by EIKE and energy expert Staffan Reveman examines whether battery parks could fully secure Germany's wind-and-solar power, finding current storage (≈26 GWh) far short. It estimates 600 GWh for a 10-hour buffer and 12,000 GWh (≈60 million tonnes, 600 km²) for ten days, implying much higher costs and the need for flexible plants or imports.
Scoring Rationale
Provides concrete national-scale estimates and implications; credibility limited by single-source analysis and contested EIKE perspective.
