Dec 4 (Reuters) - Glenfarne's Alaska LNG unit said on

Thursday it finalized an agreement to supply 1 million tonnes

per annum of liquefied natural gas to South Korean trading firm

POSCO International for 20 years from its planned

export project.

This follows a preliminary agreement signed in September.

Global demand for the superchilled fuel has surged since

Russia's invasion of Ukraine upended gas markets in 2022,

driving buyers in Europe and Asia to lock in long-term supply

deals with U.S. exporters.

Since becoming majority owner and lead developer in the

Alaska LNG project in March, Glenfarne has secured preliminary

commercial commitments with buyers in Japan, Korea, Taiwan and

Thailand for 11 mtpa of LNG.

As part of the agreement, POSCO will also make a capital

investment of an undisclosed amount in Alaska LNG before the

final investment decision, and provide a significant portion of

the steel for the 807-mile pressurized natural gas pipeline.

The LNG pipeline will link the state's North Slope gas

reserves to Southcentral Alaska and its planned export terminal,

with Glenfarne aiming for a final investment decision by the end

of the year.
