Role of underground storage in gas supply system

U radu se govori o ulozi skladišta prirodnog plina u plinskom sustavu, a glavna uloga skladišta prirodnog plina jest mogućnost iskorištavanja prirodnog plina iz skladišta kada imamo veliku potražnju plina. Opisane su karakteristike prirodnog plina, transportnog sustava i oblici podzemnih skladišta plina. U sigurnosti opskrbe prirodnim plinom veliku ulogu imaju transportni sustav i s njime povezana skladišta prirodnog plina. Navedeni su važni projekti, kako za europske zemlje, tako i za Republiku Hrvatsku koji bi osigurali bolju sigurnost opskrbe prirodnim plinom. Opisano je jedino podzemno skladište plina u Republici Hrvatskoj, te planirana skladišta plina u Republici Hrvatskoj. Također, dan je osvrt i na druge europske zemlje i njihove kapacitete podzemnih skladišta plina.This paper discusses the role of underground natural gas storage in the gas system. Main role of underground natural gas storage is to supply natural gas from storage during period of large demand. Characteristics of the natural gas transportation system and forms of underground gas storage facilities are described. Security of natural gas supply is based on the gas transport system associated with underground gas storage. Also, many important projects to ensure better security of natural gas supply are mentioned for European countries including Croatia. Current underground gas storage facility in the Croatia is described as well as planned gas storages in Croatia. Review for other European countries capacities of their underground gas storages is given
