U.S. Approves $8.2 Billion Offshore LNG Port Near Texas; Investment Decision Expected in 2027

A proposed $8.2 billion liquefied natural gas export port off the Texas coast has cleared a major federal regulatory hurdle. Whether it will actually be built remains undecided.

The U.S. Maritime Administration approved the deepwater port license application for ST LNG on Oct. 28. The planned facility would sit approximately 10.4 miles offshore from Matagorda, southwest of Houston, with enough capacity to export 8.4 million metric tons of liquefied natural gas each year.

The scale is considerable: four liquefaction systems rated at 2.1 million metric tons annually, along with offshore platforms, floating storage units, mooring equipment and pipelines connecting to existing natural gas infrastructure. But regulatory approval is only one milestone between a proposal and a working terminal.

The company still needs customers and financing

ST LNG expects to make its final investment decision in mid-to-late 2027, a year after the federal approval. It is pursuing long-term sales commitments from buyers in Asia and Europe and arranging the financing needed to move forward, Reuters reported after speaking with the company.

The company wants at least 2 million metric tons of annual purchase commitments before it approves the first phase. Additional liquefaction units could follow as more contracts are signed. ST LNG has discussed a phased approach rather than assuming the entire 8.4-million-ton capacity will be built at once.

That timetable differs from the government’s projection. The Maritime Administration’s approval announcement anticipated construction starting in 2027 and operations beginning in 2029, while ST LNG’s more recent outlook targets commercial service around mid-2030. Neither date is guaranteed until investment, contracts and remaining approvals are in place.

Why build an export port offshore?

Most large LNG export facilities process natural gas on land before loading the refrigerated liquid onto specialized ships. The Matagorda proposal instead places liquefaction and storage infrastructure at sea, away from busier coastal terminals.

The federal plan calls for 20 platforms, four floating LNG storage units, four mooring systems and about 7.7 miles of pipeline. The port would receive natural gas from the Tres Palacios storage and trading hub and the Williams Markham processing plant through pipeline connections.

Its offshore location is designed to reduce competition for space with other vessel traffic. It also presents engineering and environmental questions associated with operating industrial facilities in Gulf waters, including storms, marine habitats and vessel movements.

The project’s federal environmental review took 410 days, considerably faster than the historical average for deepwater port licensing. The underlying federal regulatory docket contains its environmental review and licensing materials.

Thousands of jobs are projected, not yet created

Federal projections put construction employment at about 2,000 jobs and permanent employment at up to 855 if the project proceeds. Those are estimates for a completed development, not positions currently available from a project under construction.

The proposed terminal also reflects the continued importance of the Gulf Coast to U.S. energy exports. Expansion of LNG infrastructure has raised hopes for new industrial jobs and export revenue while also intensifying debate over climate emissions, shipping and the effects of major energy installations on coastal communities.

In Matagorda County, the immediate development is the license decision. The next determining event will be the company’s decision to commit billions of dollars, supported by customers and lenders. Until then, the $8.2 billion port remains an ambitious, federally approved proposal rather than a construction project already underway.
