MOSCOW (Sputnik) — According to Balla, Hungary could store over 3 billion of cubic meters of gas.
"We have also looked at the issue of how the Russian side could take part in underground storage being filled up with Russian gas. We made this proposal and hope that the Russian side will show its interest in the process of filling up the underground storage on the basis of commercial cooperation," Balla told RIA Novosti.
Last month, Foreign Minister Peter Szijjarto said that Hungary was increasing the supply of gas from Russian energy company Gazprom to store in underground facilities in support of energy security.
Currently, Hungary receives most of its gas supplies from Russia via a pipeline transiting Ukraine.
