Alaska LNG:

A major investment announcement has brought renewed attention to Alaska's long-planned natural gas export project. American Factory Tracker examines what was announced, what has been committed, and what remains before the pipeline and export facilities can move into major construction.

Key facts

Planned pipeline length: Phase One / full project

Bottom line
On September 30, 2026, President Trump announced that South Korea would invest about $54 billion in Alaska LNG, as part of a $200 billion package tied to the 2025 U.S.–South Korea trade agreement.[9][10]
South Korea's government describes its role more cautiously. Industry Minister Kim Jung-kwan said the two countries have agreed to review the project jointly and that Korea will not proceed unless it is commercially viable. Seoul says the project's cost, timetable, and investment structure have not been decided. The sources reviewed do not confirm a binding South Korean financing commitment.[11][12][13]
As of September 30, Reuters reported that developers were still targeting a final investment decision on the pipeline in 2026 and on the export terminal in 2027. The sources reviewed do not confirm that either decision has been made or that project financing has closed.[14]
What does the project include?
Alaska LNG is an existing proposal led by developer Glenfarne, which owns 75 percent; the State of Alaska owns 25 percent through the Alaska Gasline Development Corporation.[15][16] It would move North Slope natural gas through a gas treatment facility at Prudhoe Bay and a 42-inch pipeline to a liquefaction and export terminal at Nikiski, on Cook Inlet in Southcentral Alaska.
The developer describes two financially independent phases:
- Phase One: a 739-mile pipeline to serve Alaska's in-state gas needs.
- Phase Two: extends the pipeline to its full 807-mile length and adds the liquefaction and export facilities.[17][18]
The federal FAST-41 dashboard lists all 20 tracked environmental review and permitting processes as complete.[19]
Where does construction stand?
In January 2026, Glenfarne said Phase One had entered “early execution.” That included conditional contractor awards and preliminary pipe-supply agreements.[20] At that time, the company said it hoped to begin laying pipe as early as December 2026.[21] The sources reviewed do not confirm that major pipeline construction has begun.
Why are cost and financing uncertain?
The project has faced years of uncertainty over cost, financing, and commercial viability. Reuters reports that developers have estimated its cost at $44.5 billion to $54.5 billion.[22]
What should readers watch next?
The next milestones to watch:
- The outcome of the joint U.S.–South Korea viability review, and any binding agreement that follows
- Binding customer contracts
- A final investment decision on Phase One, and later on the export terminal
- Documented construction progress
