The energy turnaround in Germany is an ambitious project with enormous environmental and economic impact. The conversion of the energy supply aims to combine climate protection with nuclear phase-out and the expansion of renewable energies. From today’s perspective, climate protection targets can only be achieved if coal and gas power plants are largely replaced by wind and solar power plants in the electricity generation process.
However, a weather-dependent energy supply poses some challenges for our industrial location. For if the sun does not shine and the conditions are windless, households and industry will have too little electricity. Windy, sunny days, however, produce more electricity than we need. Unfortunately, until now, there have not been enough power storage facilities to save this power surplus for “leaner” times. Existing technologies are either not yet fully mature, too expensive or have comparably low efficiency levels.
