A process and a corresponding system for the accumulation and use of thermal energy at medium or high temperatures, wherein a primary heat-carrier fluid is accumulated in a secondary accumulation section; it is subsequently fed to a heating section, where the primary fluid is heated and receives thermal energy; then, once heated, it is fed to a primary accumulation section, where the primary fluid is accumulated at the maximum temperature and from where it is collected for heat exchange with a secondary fluid, as part of a thermodynamic cycle for the production of electrical/mechanical energy; and wherein finally the primary fluid, after transferring heat to the secondary fluid and thereby cooling down, is fed and returns again to the secondary accumulation chamber, thus closing the cycle. Advantageously, the primary and secondary accumulation sections of the primary fluid, both epigeal and hypogeal, are of the tankless type, so that they do not involve the use of self- supporting tanks, or similar containers, and can be constructed in various ways, for example with a geological/artificial barrier, or in one or more natural cavities, such as those formed in a rock salt mine, or artificial cavities, provided or not with reinforcement and/or containment works. Moreover the primary heat-carrier fluid, used in this process to accumulate thermal energy, can be of the type including organic substances such as bitumen and/or the like. |
