Glenfarne Alaska LNG, LLC and POSCO International Corporation announced an agreement to advance a strategic partnership for the development of the Alaska LNG Project, the only federally authorized LNG export project on the U.S. Pacific Coast.
The partnership will include steel supply, LNG offtake, and an investment with respect to the Alaska LNG project. The agreement defines the process for Glenfarne and POSCO to move forward on definitive agreements, which will close pending board approvals by both sides.
This agreement will include initial terms for POSCO to supply a significant portion of the steel required for Alaska LNG’s 807-mile, 42-inch pressurized natural gas pipeline. The Alaska LNG pipeline will connect Southcentral Alaska, home to Alaska’s population center and the Alaska LNG export terminal, with Alaska’s vast, stranded natural gas resources on the North Slope. Glenfarne is targeting a year-end FID for the Alaska LNG pipeline.
The agreement will include initial terms for a 20-year Heads of Agreement for 1 million tonnes per annum of LNG offtake on a Free-on-Board basis. This will be the first announced HOA for Alaska LNG.

Glenfarne Group Chief Executive Officer and Founder Brendan Duval and POSCO International Corporation Chief Executive Officer Kye In Lee signed a commercial agreement to advance the Alaska LNG Project on September 10, 2025 at the Gastech energy conference in Milan.
Alaska LNG is a joint venture between Glenfarne, majority owner and lead developer of Alaska LNG, and the state-owned Alaska Gasline Development Corporation. POSCO is the largest sales representative of POSCO Group (Korea’s largest steel producer) and a major Korean LNG importer.
Glenfarne Chief Executive Officer and Founder Brendan Duval said, “POSCO’s participation in Alaska LNG adds tremendous momentum as we drive this signature North American LNG project forward at a rapid tempo. This agreement includes critical project components and demonstrates global support for unlocking some of the most strategically located LNG in the world. Korea is a valued target market for Alaska LNG and we greatly appreciate POSCO’s engagement as we advance Alaska LNG.”
Glenfarne Alaska LNG President Adam Prestidge said, “POSCO is one of the world’s foremost steel companies, a leading LNG importer in one of Alaska LNG’s most important markets, and now a significant partner in Alaska LNG. POSCO’s involvement underscores the project’s strategic, geographic, and economic competitive advantages as we rapidly progress toward a final investment decision on the Alaska LNG pipeline.”
This announcement closely follows Alaska LNG’s announcement yesterday of the execution of a letter of intent with JERA Co., Inc.
The Alaska LNG project consists of a pipeline capable of transporting enough natural gas to meet both Alaska’s domestic needs and supply the full 20 MTPA Alaska LNG export terminal in Nikiski, Alaska. Further accelerating the project’s execution, the pipeline will be built in two independent, financially viable phases. Phase One will deliver natural gas approximately 765 miles from the North Slope to the Anchorage region. Phase Two includes the Alaska LNG facility, approximately 42 miles of pipeline under Cook Inlet, and pipeline compression equipment. Glenfarne is working with Worley to complete the final engineering for the domestic portion of the Alaska LNG pipeline and targeting a year-end pipeline final investment decision.
Glenfarne’s permitted North American LNG portfolio totals 32.8 MTPA of capacity under development in Alaska, Texas and Louisiana.
