European gas traders have more than quadrupled the volume of natural gas they store in western Ukraine’s underground reservoirs, reports Ukrtransgaz. Offshore companies have parked 5.3 billion cubic meters under a customs warehouse regime that allow them to store gas duty free, paying only rent. As Europe’s gas reservoirs fill up with cheap gas, the number of companies storing gas in Ukraine has jumped to 68 today, from 28 this time last year.
