20.500.12556/DKUM-98915 Results of the HESS project – hybrid energy storage system in post- mining infrastructure Rezultati projekta HESS – Hibridni sistem shranjevanja energije v post-rudarski infrastukturi The project`s aim was to develop a Hybrid Energy Storage System (HESS) consisting of three different energy storage systems: Pumped Storage Hydroelectricity (PSH), Compressed Gas – Air/CO2 Energy Storage (CAES) and Thermal Energy Storage (TES) using a post-mining infrastructure. The possibility of using geothermal energy and the use and potential storage of CO2 were also included in the research. The assumed total energy storage capacity in the HESS project was in the range of 30 MWh. On the basis of the energy demand of each HESS component, a method of thermal and mechanical integration of the entire system was investigated and developed, together with an algorithm for the mutual interaction between the elements of the energy storage system. The optimal cooperation of the various elements of the HESS was decided to be supervised by an energy router. The router also manages energy exchanges with the national power grid for the intake of low-cost green energy and peak energy production. The single HESS energy router system should take into account the possibility of the cooperation of multiple HESS systems working in a distributed system. Cilj projekta je bil razviti hibridni sistem za shranjevanje energije (HESS), ki ga sestavljajo trije različni sistemi za shranjevanje energije: črpalna hidroelektrarna (PSH), shranjevanje energije s stisnjenim plinom – zrakom/CO2 (CAES) in shranjevanje toplotne energije (TES) z uporabo infrastrukture po rudarjenju. V raziskavo je bila vključena tudi možnost uporabe geotermalne energije ter uporaba in potencialno shranjevanje CO2. Predpostavljena skupna zmogljivost shranjevanja energije v projektu HESS je bila v območju 30 MWh. Na podlagi potreb po energiji vsake komponente HESS je bila raziskana in razvita metoda toplotne in mehanske integracije celotnega sistema, skupaj z algoritmom za medsebojno interakcijo med elementi sistema za shranjevanje energije. Za optimalno povezovanje različnih elementov HESS je bil izbran kontrolnik - usmerjevalnik energije. Usmerjevalnik upravlja tudi izmenjave energije z nacionalnim elektroenergetskim omrežjem za prevzem nizkocenovne zelene energije in konic energije. Enotni sistem usmerjevalnika energije HESS mora upoštevati možnost sodelovanja več sistemov HESS, ki delujejo v povezanem sistemu. energy storage post-mining infrastructure pumped storage hydroelectricity compressed gas – air/CO2 energy storage thermal energy storage RFCS Project HESS shranjevanje energije infrastruktura na območjih nekdanjih rudnikov črpalne hidroelektrarne shranjevanje energije s stisnjenim plinom (zrak/CO2) shranjevanje toplotne energije projekt RFCS HESS true true true Angleški jezik Slovenski jezik Znanstveno delo 2026-07-17 09:09:48 2026-07-17 09:09:49 2026-07-18 03:13:03 0000-00-00 00:00:00 2026 0 0 str. 5-29 št. 1 Letn. 19 jul. 2026 0000-00-00 NiDoloceno Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-07-01 620.92:621.311.25:681.5 285098499 10.18690/jet.19.1.5-30.2026 1855-5748 RAZ_Jamnikar_Sergej_2026.pdf RAZ_Jamnikar_Sergej_2026.pdf 1 FEFB963981ADC1F4673897AC6D535394 0ab793288fbda0a65937a872c99e35c6dccd8e547f2c6d805dd38c5be2d17c60 a0b05257-81ae-11f1-a6d3-00155d580e34 https://dk.um.si/Dokument.php?lang=slv&id=208350 https://doi.org/10.18690/jet.19.1.5-30.2026 0 acb7fe54-81ae-11f1-a6d3-00155d580e34 https://dk.um.si/Dokument.php?lang=slv&id=208351 Fakulteta za energetiko Journal of energy technology 0 0 0
