The call topic is open to different sources of innovation: material research, development and testing of a component, device or device cluster, simulation of systems or system components, etc. and the integration of the innovation in the energy system.
The topic addresses a multitude of different energy storage technologies and their combinations for enabling long duration (from several hours to months) energy storage and is explicitly open to all technology readiness levels (TRLs).
Further assessment of the EU energy storage needs (regardless of short or long-duration) are also strongly invited and encouraged.
