摘要
Energy storage systems represent one of the most concrete solutions for solving the main two limits of the renewable energy sources (RES): punctuality and not programmable generation. Among them, Compressed Air Energy Storage (CAES) technology is an efficient, low cost, and extremely adaptable option for small scale applications. In the present paper performances of a volumetric unidirectional-flow turbine has been studied. This turbine shows good efficiency also when high-humidity air is expanded, because condensation phenomena do not affect turbine performances. Firstly the experimental apparatus has been realized, then the plant theoretical efficiency has been calculated. This value has been thus compared with the experimental efficiency. Finally theoretical study has been carried out evaluating the possibility to substitute air with waste evolving fluids like flue gas and lime kiln gas, in order to increase the plant efficiency and, reuse these gaseous mixtures. Results show that both flue gas and lime kiln gas allow to increase plant efficiency, so they could represent an interesting option for performing CAES systems.
