But experts say Ukraine has no real short-term energy options outside of Russian imports, even as Gazprom claims that Ukraine already owes it $2.24 billion from supplies delivered before April.
"It would be cheaper for Ukraine to just burn their furniture," John Kilduff, founding partner at commodities investment manager AgainCapital, told CNBC.
In its efforts to move away from Russia, Ukraine has tried to kickstart "reverse" natural gas flow trades with Western countries such as Slovakia. Such an arrangement would import natural gas into Ukraine from the west through pipelines originally designed to carry Russian oil from the east through Ukraine. However, those countries receive the majority of their gas from Gazprom as well. Slovakia alone imports about 168 billion cubic feet of natural gas from Russia per year.

"On a purely infrastructural level, yes, it (reverse gas flow) is possible. The pipeline exists and the gas exists. It's more a matter of political will than technical ability," Blaise Misztal, director at Foreign Policy Project told CNBC. "How far is Europe willing to go to spite Russia?"
Misztal is not alone in believing that reversing gas flow is not the solution to Ukraine's energy problems, largely as a result of the geopolitical friction it could cause. Kilduff of AgainCapital told CNBC that the potential price increase as a result of reversing the flow and spiting Russia could be staggering to European consumers.
