The U.S. Energy Department said on Thursday it has approved Oregon LNG to export liquefied natural gas, as the Obama administration works through applications to export fuel from the domestic drilling boom to markets in Asia and Europe. Oregon LNG, which is controlled by Leucadia National Corp , has been authorized by the department to export up to 1.25 billion cubic feet per day of the fuel. The Astoria, Oregon-based project still needs approval from the Federal Energy Regulatory Commission.
