South Korea Cautious on Trump Push for Alaska LNG Investment

President Donald Trump’s push to steer $54 billion of South Korean investment into Alaska LNG has thrust a high-cost 20 million-ton-a-year export project into the spotlight, reuters.com reported on Oct. 1. The proposed infrastructure development carries a massive price tag of $44.5 billion to $54.5 billion, running more than double the cost of comparable U.S. Gulf Coast plants. Project Costs And Pipeline Demands

Lead developer Glenfarne Group estimates that building Alaska LNG will cost roughly $2.2 billion to $2.7 billion per million metric tons per annum of capacity. By comparison, Gulf Coast export terminals approved since Russia’s invasion of Ukraine generally average about $1 billion per mtpa or less. Cheniere Energy’s Corpus Christi Stage 3 expansion cost about $8 billion for 10.5 mtpa, and Venture Global’s Plaquemines LNG required roughly $21 billion for 20 mtpa. Unlike Gulf Coast terminals that tap extensive shale gas networks in Texas, Louisiana, and Appalachia, Alaska LNG requires an 800-mile pipeline from the North Slope down to a Nikiski terminal. Glenfarne estimates the pipeline alone will cost $13.2 billion to $16.9 billion. The project also requires a large North Slope treatment plant priced between $7.7 billion and $9.2 billion, alongside a liquefaction terminal costing $23.6 billion to $28.4 billion. South Korean Funding And Commercial Viability

President Trump unveiled the investment push as part of a broader $200 billion South Korean package. Seoul responded by stating it has not yet decided whether to fund Alaska LNG and must first review the project’s commercial viability. Jason Feer, head of business intelligence at Poten & Partners, noted that the core question is whether Asian buyers are willing to pay a premium for supply security, adding that markets have not seen evidence of that willingness so far. Alex Munton, director of global gas and LNG research at Rapidan Energy Group, stated that the project may struggle to meet commercial thresholds for investment. Strategic Advantage Versus Market Realities

Supporters argue that Alaska LNG’s northern geography provides a strategic shipping advantage. Cargoes would reach key Asian importers including Japan, South Korea, and Taiwan significantly faster than shipments leaving the Gulf Coast, thereby lowering transport costs. Jack Weixel at East Daley Analytics suggested that while Asia needs stable gas supplies and might pay a premium, Canadian projects in the same region present competing advantages. Glenfarne CEO Brendan Duval expressed confidence that President Trump’s announcement would help gather the necessary capital to accelerate Alaska LNG toward a final investment decision and construction.

“These LNG developers should be looking at any and all options as the global market for natural gas, particularly among non-OECD nations, grows. But, some will work better than others.”
