Conflict between Russia and Germany risks leaving one of central Europe’s biggest natural gas depots empty next winter, just as the continent urgently needs to ensure supplies due to the war in Ukraine.

The Haidach underground depot -- located in Austria but connected only to the German grid -- is unlikely to get filled after Moscow cut supplies to a Gazprom PJSC unit seized by Berlin’s government, according to energy officials in Vienna, who asked not to be identified in exchange for discussing sensitive topics. The depot is equivalent to about a quarter of Austrian storage capacity.
