Dunkelflaute

From Wikipedia, the free encyclopedia
A short dunkelflaute of one day on Tuesday on the right graph.

Dunkelflaute (German: [ˈdʊŋkəlˌflaʊtə], lit. 'dark doldrums' or 'dark wind lull'[1]) is a term used in the renewable energy sector to describe a period of time in which little to no energy can be generated with the use of wind and solar power.[2][3][4] These periods are a big issue in energy infrastructure, in which a significant amount of electricity is generated by renewables.[5][6] To ensure power during such periods alternative energy sources must be present in a sufficient capacity, energy can be imported or demand can be adjusted.[7] For alternative energy sources, countries use either fossil fuels (coal, oil and natural gas), hydroelectricity or nuclear power and, less often, energy storage to prevent power outages.[8][9][10][11][12] A group of countries is following on from Mission Innovation to work together to solve the problem in a clean low-carbon way by 2030: including looking into carbon capture and storage and the hydrogen economy as possible parts of the solution.[13]
