President Donald Trump is expected to announce plans for South Korea to invest about $54 billion in the long-delayed Alaska liquefied natural gas project, according to Reuters and the Associated Press. The Alaska commitment forms part of $200 billion in strategic US investments tied to a wider trade agreement between Washington and Seoul. The announcement is expected to identify the LNG development as one of the first major projects to draw funding from the program.
The proposed Alaska LNG system would carry natural gas from the North Slope through an 807-mile pipeline to a liquefaction plant on Alaska’s southern coast, allowing cargoes to be shipped to Asian customers. The White House said the project is designed to transport about 3.9 billion cubic feet of gas per day and produce as much as 20 million metric tons of LNG annually. The broader South Korean package is also expected to include eight large nuclear power plants and a 6-gigawatt gas-fired generation facility in Texas.
The funding comes from commitments made under a 2025 US-South Korea trade agreement. South Korea pledged $350 billion of US investment in exchange for lower American tariffs on South Korean vehicles, auto parts and other goods. Of that total, $150 billion was allocated to shipbuilding cooperation and $200 billion to strategic projects. Reuters reported that Seoul requires projects supported by the program to meet commercial-viability standards, an important condition for developments that place public capital at risk.
Alaska LNG has faced years of uncertainty over cost, financing and demand. Reuters said the development has been estimated at between $44.5 billion and $54.5 billion, with the pipeline alone projected to cost between $13.2 billion and $16.9 billion. Developer Glenfarne Group owns 75% of the project, while the state of Alaska holds the remaining 25%. The project is targeting a final investment decision on the pipeline in 2026, a decision on the export facility in 2027 and first LNG exports in 2031.
Commercial support is still incomplete. Glenfarne said in March that it had assembled commitments covering 13 million metric tons of LNG per year, but needed another 3 million tons to secure financing and make the commitments binding. Japan’s JERA and Tokyo Gas have signed preliminary agreements to purchase a combined 2 million metric tons annually if the project is built. Reuters noted that most agreements secured so far are non-binding, while the development also faces competition from lower-cost US Gulf Coast and Canadian LNG export projects.
What it means for traders: The announcement could improve the financing outlook for a large new source of US natural-gas exports, but it does not by itself amount to a final investment decision or guarantee construction. For Natural Gas markets, the relevant scenarios are whether South Korean funding becomes binding, whether additional long-term customers sign firm purchase agreements and whether the pipeline and liquefaction stages meet their planned approval timetable. The next points to watch are the detailed investment terms, Seoul’s commercial review, additional LNG sales contracts and the targeted 2026 pipeline decision.
