The term climate change describes one of the greatest challenges of the 21st century. Alternative energy supply systems, sustainability and resource efficiency are constantly moving further into the focus of actors in politics, business, science and technology. The overarching goal is to reduce emissions that are harmful to the climate. In the future, a complete transformation of the entire energy sector is on the horizon. The innovations extend across the sectors of extraction, conversion, distribution and storage of the energy to be provided on the required scale.

Against this background, the sector of large-scale energy storage, in particular, represents a major challenge for the targeted developments, since, for example, the demand for electrical power is never in equilibrium with its generation from renewable energy sources. There is still a lack of appropriate storage options and storage capacities to buffer fluctuating light intensities and wind speeds in such a way that there is never an undersupply or oversupply of electricity.
