Thailand supports Alaska LNG with PTT agreement

Glenfarne Group, through its subsidiary Glenfarne Alaska LNG, has strengthened the momentum of the Alaska LNG project through a co-operation agreement with PTT of Thailand, witnessed by Thailand’s Permanent Secretary of Energy, Dr Prasert Sinsukprasert.

The agreement, signed in June 2025 in Bangkok, Anchorage and New York, provides for PTT to procure 2M tonnes per annum (mta) of LNG from Alaska LNG over a 20-year term. PTT is Thailand’s publicly traded national oil and gas company.

The ceremony was attended by Dr Prasert and by Robert Godec, the United States Ambassador to Thailand.

Glenfarne Alaska LNG president Adam Prestidge said the company was pleased PTT and the Thai government had recognised the advantages of the Alaska LNG project.

Glenfarne chief executive and founder Brendan Duval stated the agreement reflected the project’s growing momentum, adding Alaska LNG would address both Alaska’s domestic gas shortage and create opportunities for employment and business growth.

The PTT agreement followed Glenfarne’s announcement earlier in June 2025 that over 50 companies had expressed interest in partnerships with Alaska LNG, representing potential contract value exceeding US$115Bn. Expressions of interest came from the United States, Japan, Korea, Taiwan, Thailand, India and the European Union.

Mr Duval commented these responses showed recognition of Alaska LNG’s economics and the necessity of the pipeline to secure long-term supply in south central Alaska.

Progress on the pipeline’s development continues. In May 2025, Glenfarne appointed Worley to undertake final engineering and prepare a cost estimate for the Alaska LNG pipeline to support a final investment decision.

Mr Duval said declining gas production from Cook Inlet heightened the urgency of the project, while Worley Americas president Mark Trueman said his team was well placed to assist in advancing the scheme.

These developments build on the March 2025 binding agreements between Glenfarne and AGDC that confirmed Glenfarne as the majority owner and lead developer of the Alaska LNG project.

AGDC retains a 25% interest in 8 Star Alaska, the project entity, and continues to support its progression. The project comprises an 1,300-km, 42-inch pipeline, a 20-mta export terminal at Nikiski, and a North Slope carbon capture facility.

The involvement of Thailand’s energy ministry in the PTT signing underlines the wider geopolitical and regional interest in Alaska LNG, positioning the project as both a domestic supply source and a Pacific-facing export platform.
