There are two major factors that have emerged in the last five years that have sparked a surge in LNG investments. First is the shale gas “revolution” in the United States, which allowed the U.S. to vault to the top spot in the world for natural gas production. This caused prices to crater to below $2 per million Btu (MMBTu) in 2012, down from their 2008 highs above $10/MMBtu. Natural gas became significantly cheaper in the U.S. than nearly everywhere else in the world.
