4TunaTES
4TunaTES will unlock the potential thermal energy storage by delivering a groundbreaking flexible Thermo-Chemical Energy Storage (TCES) technology that can be easily adapted to different applications (variable in- and output temperatures) and thereby reduce the development costs by 90%.
4TunaTES will develop a TCES-prototype that can be also used for domestic use and addresses different challenges in terms of materials used, heat exchanging components with a high degree of manufacturing flexibility, and revolutionary systems with electricity adapted thermodynamic cycles.
