Efficient and scalable energy storage systems capable of loading and discharging energy streams with high thermodynamic value (i.e., high exergy) are paramount in the envisaged decarbonized economy.

This talk will first give an overview of the current state of the art in the field of storage of high temperature energy. The presentation will encompass a techno-economic comparison of current available alternatives. The second part of the talk will deal with recent research advancements in the same field, with the focus being on solutions which proved already promising at least at the lab-scale.
