This paper contains an experimental analysis of a heat storage tank's heat loss and exergy efficiency using a basalt porous bed as a storage material. The basic parameters of the laboratory bench with measuring equipment are presented and the experimental procedure is discussed. The methodology for evaluating the energy potential of the heat storage process for large-scale energy storage systems is described. The main novelty of the presented system is the application of the slenderness of the heat accumulator, which corresponds to the development of the system in a post-mining shaft. Based on the analysis of the experiment, the exergy cycle efficiency of the heat storage unit was determined to equal 52.3%, and the energy efficiency equal to 96.6%.

W artykule przedstawiono obecny stan technologii magazynowania energii w postaci sprężonego powietrza. W oparciu o odpowiednie modele dynamiczne takich instalacji i symulacje procesów ładowania i rozładowania, przedstawiono możliwe do osiągnięcia efektywności magazynowania energii oraz towarzyszące im różnorakie definicje. Pokazano możliwości współpracy magazynów CAES ze źródłami odnawialnymi takimi jak turbiny wiatrowe czy ogniwa słoneczne, tworzące w ten sposób układy hybrydowe. Na podstawie dostępności kawern, zaproponowano szereg lokalizacji takich magazynów na terenie Polski.

The article presents a current state of development of compressed air energy storage technology (CAES). Based on the appropriate dynamic models of such installations and simulations of the loading and unloading processes, the achievable energy storage efficiency and the various definitions accompanying them were shown. Opportunities for CAES to cooperate with renewable sources such as wind turbines and solar cells, thus creating hybrid systems were also pointed out. Based on the availability of caverns, a number of locations of such a storage were proposed in Poland.

Compressed Air Energy Storage (CAES) technology and electricity generation by this system are described in this paper. General performances and possible system efficiency definitions of those kinds of systems are indicated. Hybrid systems which consist of CAES and other Renewable Technologies - RT - (e.g. wind turbines) are presented. A possible location for CAES–RT in Poland is indicated. A dynamic mathematical model of CAES is presented; using this model the results for compressing and expanding operating modes are obtained.

The article presents a dynamic analysis of the compressed air energy storage in the car. The analysis was used to determine those processes most relevant to achieving highest possible efficiency. A review of the state of the art is presented. Simple technical-economic analysis of usage those kind of cars is also performed and discussed by taking Polish local conditions from an electricity market. Main advantages as well as drawback of the compressed air cars are pointed out.
