KONCEPCJA SYSTEMU ZBIORNIKÓW IZOBARYCZNYCH NA DWUTLENEK WĘGLA

The progressive decarbonization process and increasing share of unstable renewable energy sources in the energy market in recent years is the reason for continuous search for more efficient, cheaper, more capacious and more durable energy storage facilities. The paper presents the results of work on the concept of a system of isobaric carbon dioxide tanks. This system is subject to patent application in the Patent Office of the Republic of Poland under number P.437305 and is to become a component of energy storage systems, where carbon dioxide will be used as an energy carrier. The idea of such storages is based on the transformation of electric energy into the potential energy of compressed gas and then recovering the stored energy by reversing the direction of the process, i.e. expanding the stored carbon dioxide in the expander, thanks to which the stored energy is given back to the grid during a shortage of electric energy. This paper presents the principle of the isobaric storage system, its structure and components, and the assumptions made in the concept. The results of work on the algorithm allowing the selection of geometric features of individual components of the isobaric system are also presented.
