U.S. Expands LNG Export Capacity at Corpus Christi Terminal

On March 4, 2026, U.S. Secretary of Energy Chris Wright signed an export authorization for a 12% expansion of liquefied natural gas (LNG) exports at Cheniere Energy’s Corpus Christi LNG Terminal in Texas. This authorization permits additional exports of up to 0.47 billion cubic feet per day (Bcf/d) to non-Free Trade Agreement (non-FTA) countries, bringing the total export capacity of the terminal to 4.45 Bcf/d. This makes it the second-largest LNG export project in the United States.

The expansion is part of the Midscale Trains 8 & 9 Project, which follows a positive final investment decision announced by Cheniere Energy in June 2025. The project is expected to significantly contribute to the U.S. position as the world's largest LNG exporter, with exports having surged from 0.5 Bcf/d in 2016 to a projected 15.0 Bcf/d in 2025.

The Corpus Christi LNG terminal has been operational since 2018, and the recent authorization allows for exports until 2050, with a three-year extension for remaining volumes post-expiration. The U.S. Department of Energy (DOE) has approved over 18.2 Bcf/d of LNG export authorizations since the Trump administration lifted the previous ban on non-FTA exports. This volume exceeds the export capacity of the world's second-largest LNG exporting nation.

The Stage 3 Project at Corpus Christi consists of seven mid-scale trains, with a total capacity exceeding 10 million metric tons per annum (MMtpa). As of early 2026, substantial completion of the first four trains was achieved, and production from train 5 commenced in February 2026.

Secretary Wright emphasized the significance of this expansion, stating, “This order helps further strengthen America’s LNG export capacity, delivering peace abroad and prosperity for Americans at home.” He highlighted the role of American innovation and leadership in transforming the U.S. into the leading LNG exporter globally. Kyle Haustveit, Assistant Secretary of the Hydrocarbons and Geothermal Energy Office, noted that the commitment to LNG exports is aimed at ensuring a stable energy future and driving economic prosperity.

While the expansion has been largely welcomed, some critics argue that increased LNG exports could lead to higher domestic energy prices and environmental concerns associated with natural gas extraction and transportation. The long-term implications of expanding fossil fuel exports in the context of climate change remain a contentious issue among environmental groups.

There is a discrepancy in the projected LNG export figures, with the Energy Information Administration (EIA) forecasting U.S. LNG exports to exceed 18.1 Bcf/d by 2027, while other sources indicate varying estimates for future export capacities. Additionally, the pending application with the Federal Energy Regulatory Commission (FERC) for further capacity increases remains unresolved.
