There is a growing interest in the electrical energy storage system, especially for matching intermittent sources of renewable energy with customers' demand. Furthermore, it is possible, with these system, to level the absorption peak of the electric network (peak shaving) and the advantage of separating the production phase from the exertion phase (time shift). CAES (compressed air energy storage systems) are one of the most promising technologies of this field, because they are characterized by a high reliability, low environmental impact and a remarkable energy density. The main disadvantage of big systems is that they depend on geological formations which are necessary to the storage. The micro-CAES system, with a rigid storage vessel, guarantees a high portability of the system and a higher adaptability even with distributed or stand-alone energy productions. This article carries out a thermodynamical and energy analysis of the micro-CAES system, as a result of the mathematical model created in a Matlab/Simulink ® environment.New ideas will be discussed, as the one concerning the quasi-isothermal compression/expansion, through the exertion of a biphasic mixture, that will increase the total system efficiency and enable a combined production of electric, thermal and refrigeration energies. The exergy analysis of the results provided by the simulation of the model reports that more than one third of the exergy input to the system is lost. This is something promising for the development of an experimental device.

“…So an energy storage system is designed and applied in this hybrid system to provide steady and predictable output power. In the last decades, several energy storage systems including pumped hydro storage (PHS), flywheel energy storage system (FESS), compressed air energy storage (CAES), and so on [17,18], have been investigated and used to improve the renewable energy penetration level and power quality. Since the PHS and CAES are limited by geographical conditions and the short operation duration and high self-discharge losses are the main drawbacks of FESS, a hydraulic accumulator is adopted in this system as a more competitive option for energy storage system due to high power and energy density, fast response, simple maintenance requirement and economical consideration [15,19].…”

“…Main part of sustainable energy vehicles is air-powered engine, and the pneumatic-hydraulic transmission is broadly applied as the main heart of the driving system for great advantages of simple structure, recyclability, low cost, high storage density of energy and long lifespan [1][2][3]. Though the advantages are obvious, it also owns disadvantages such as low efficiency by insufficient of the energy utilization, which aggravates the waste of energy, especially under the recent environment of energy shortage and developing green movements [4,5].…”

Pneumatic-hydraulic transmission has been developed for years. However, its dynamic properties are not good enough for application. In this paper, in order to increase the output characteristics, a late-model air-powered vehicle using expansion energy is proposed which can boost energy through a pneumatic-hydraulic transmission. The dynamic characteristics of the air-powered vehicle is modeled and verified by conducting experiment. In addition, the influence of the key parameters of the air-powered vehicle is researched for the optimization of the system performance. Through the results, the author got the conclusion that, firstly, comparison of the results of model and experiment proves the built model to be effective; secondly, input air pressure should be set according to the request of the practical loads, and range of 0.65 to 0.75 MPa can be chosen; thirdly, as a key structure parameter of the airpowered vehicle, ratio of the areas is considered to be set to approximate 8; what's more, a bigger orifice with a limit will promote the system dynamic characteristic property, and the limit is about 3.5 mm; last but not the least, not too farther position of the rings will increase the quality of output dynamic characteristics. This paper can be a reference for system design of air-powered vehicle and dynamic improvement.
