Alaska LNG project is one of the largest planned energy projects in the United States. It is designed to bring natural gas from Alaska’s North Slope down to the southern coast, where it can be exported to international markets. The project will build a massive pipeline of about 1,300 kilometers, a liquefied natural gas terminal in Nikiski, and facilities to capture and store carbon emissions.
POSCO’s Entry into the Project
POSCO International from South Korea has now joined this project with a strong interest in both energy and materials. The company signed a preliminary agreement with Glenfarne, the developer of the Alaska LNG project, and with the Alaska Gasline Development Corporation.

Under this agreement, POSCO will secure one million tonnes of liquefied natural gas every year for twenty years once the project begins operation. The deal is not final yet, but it shows POSCO’s clear intention to become a key player.
Along with buying LNG, POSCO will also supply steel for the long pipeline. The pipeline will require highly durable steel that can withstand high pressure and Alaska’s extreme weather. POSCO is one of the largest steel producers in the world, so this deal allows the company to contribute both as a customer and as a supplier.
Why This Partnership Matters
The participation of POSCO gives new momentum to the Alaska LNG project. Previous efforts faced challenges because of high costs and doubts about profitability. With POSCO on board as both a buyer and supplier, the project gains stronger financial credibility.
It also sends a positive signal to other investors and buyers in Asia. For South Korea, the deal supports energy security at a time when global markets remain unstable. For Alaska and the United States, it brings in international partners who can help move the project forward after years of delay.
Even with this new agreement, many challenges remain. The deal is still non-binding, and POSCO will only finalize it if the project proves profitable. The environmental impact also raises concerns, as the pipeline will pass through sensitive areas of Alaska.
