On 19th December 2018, we were invited to a scientific meeting of the Energy Committee of the Polish Academy of Sciences in Katowice,

which took place at the Faculty of Energy and Environmental Engineering of the Silesian University of Technology in Gliwice. The meeting was attended by Sebastian Waniczek, who is a co-author of the presentation "Storage of energy in compressed air - the concept of a hybrid system". This presentation, presented by Prof. Łukasz Bartela and Prof. Marcin Lutyński, has received a great deal of concrete attention from the gathered.
