Renewable energy sources are the trend of our times. But, unfortunately, they do not always supply energy. What happens when the wind does not blow and when the sun does not shine?

Then neither solar cells nor wind turbines provide electricity. This typically happens in the Central European winter, and in Germany, the word "Dunkelflaute" (darkness and no wind) was coined for it. It describes the simultaneous occurrence of darkness and a wind lull. In such a situation, alternatives must be available that can quickly and reliably fill the gaps that arise.
