Ukraine’s vast underground gas storage returned to business in July, with European traders setting aside concerns about the war risks and diverting Russian pipeline gas destined for Europe into temporary storage inside Ukraine.

The European traders are receiving preferential treatment from Kyiv, which has long aspired to play a greater role in the continent’s energy security.

Ukraine’s gas transmission authority, Operator GTS Ukrainy, said in a statement that about 590 million cubic metres of gas went into storage facilities last month located mainly along the country’s western border.
