As the share of renewables in energy production grows so does the role for thermal energy storage. The wide range of applications for thermal energy storage presents a broad range of development conditions for advanced thermal storage technologies to supplement the existing, widely used water-based heat storage technologies. Thermal energy storage could reveal itself as a real game-changer, allowing for a notable decrease in primary energy demand, thus reducing the energy footprint. It could also support the widespread acceptance and use of renewable energy as well as the efficient use of fluctuating energy sources.

More than half of our primary energy resources are used to generate heat. Therefore, technologies for increasing the share of sustainable heat sources and for improving the efficiency of thermal systems are of key importance. Thermal energy storage technologies are needed for both – to match the intermittent supply of sustainable heat and cold and to optimize the thermal system performance. Present thermal energy storage technologies based on water perform well, but on a relatively low level of efficiency, particularly for longterm storage. These systems can only be improved marginally thus new materials and systems are needed to enable a breakthrough.
