Exxon Mobil and Qatar Petroleum announced a final decision to finance a $10 billion-plus project to export liquefied natural gas from the Texas Gulf Coast.

The decision moves forward the latest export terminal fueling growing shipments of U.S. LNG, or natural gas cooled to liquid form, for overseas travel. The Department of Energy last month forecast that LNG will play a major role in the U.S. exporting more energy than it imports by 2020, a feat the nation has not achieved in nearly 70 years.

The plan to export LNG from Exxon’s Golden Pass terminal speaks to the renaissance in U.S. energy production. The facility was originally built to import LNG, but the surge in U.S. natural gas production over the last decade means American drillers are now looking overseas for buyers, according to CNBC.

Exxon says work to retool the terminal near Port Arthur, Texas, along the Louisiana border will begin this quarter. The oil giant expects the facility to start up in 2024 and says it will ultimately be able to produce roughly 16 million tons of LNG each year.

Total U.S. LNG exports were 14.3 million tons in 2017 and climbed to 15 million tons through the first three quarters of 2018, according to Reuters. Trade in LNG reached nearly 300 million tons in 2017 and is growing, particularly in Asia, where China is switching from coal to cleaner-burning natural gas to improve air quality.
