Cold-stricken Europe is drawing a flotilla of U.S. liquefied natural gas cargoes amid an energy crisis that has sent gas prices to record levels.

Facing a winter shortage and little relief from the continent’s main supplier Russia, natural gas in Northwest Europe is trading for about $57.54 per million British thermal units, up almost a third from a week earlier. That’s roughly $24 higher than Asian prices and more than 14 times higher than gas being sold on U.S. benchmark Henry Hub.

Out of 76 U.S. LNG cargoes in transit, 10 tankers carrying a combined 1.6 million cubic meters of the heating and power plant fuel have declared destinations in Europe, shipping data compiled by Bloomberg shows. Another 20 tankers carrying an estimated 3.3 million cubic meters appear to be crossing the Atlantic Ocean and are on a path to the continent. Nearly one-third of the cargoes come from Cheniere Energy Inc.’s Sabine Pass LNG export terminal in Louisiana, the shipping data shows.

U.S. LNG export terminals are operating at or above capacity after reaching record flows on Sunday. Asia is typically the top destination for U.S. LNG cargoes, but that has changed this winter with the significant premium for gas in Europe.
