🚨New preprint: Coping with the #Dunkelflaute
▶️ Renewable energy droughts (low wind & PV) define long-duration storage
▶️ Most extreme event in 🇪🇺 occurred winter 1996/97
▶️ 351 TWh storage needed (7% of yearly electricity demand)

It depends on so many factors, like how much overbuilding (which depends on building cost), how much international conncection, how much forced demand reduction is tolerable for what time, how tolerable is a hefty, but very rare demand reduction.
