Alaska LNG Project Gains Momentum with Strategic PTT Partnership

Glenfarne Alaska LNG, a subsidiary of the U.S. energy firm Glenfarne Group, has formalized a pivotal cooperation agreement with PTT, Thailand’s state-owned oil and gas company. This agreement paves the way for PTT's involvement in the liquefied natural gas (LNG) export project currently under development in Alaska.

The newly signed agreement outlines the framework for both Glenfarne and PTT to progress toward definitive arrangements for their partnership in the Alaska LNG project. A key component of this collaboration is the commitment to supply 2 million tonnes per annum (mtpa) of LNG for a duration of 20 years.

"Glenfarne and Alaska LNG are pleased that PTT and the Thai government recognize the strategic security, cost-effectiveness, and stability offered by the Alaska LNG project," stated Adam Prestidge, President of Glenfarne Alaska LNG. He added, "With this latest agreement and previously announced partnerships, Alaska LNG has now secured 50 percent of its available third-party LNG offtake capacity with investment-grade counterparties. The project continues to generate substantial interest from additional partners worldwide."

The Alaska LNG project is designed to feature an extensive 807-mile pipeline, a critical piece of infrastructure capable of transporting sufficient natural gas to meet Alaska's domestic energy demands while also feeding the entire 20 mtpa Alaska LNG export facility. Glenfarne anticipates that the project's unique characteristics will enable it to deliver LNG to Asian markets at more competitive prices than those originating from the U.S. Gulf Coast.

The Unsung Hero: The Role of Cables in Pipeline Infrastructure

The construction of such a vast pipeline system, particularly one spanning 807 miles and traversing challenging terrains, inherently relies on a complex network of cables. These aren't just the power lines you see overhead; they encompass a wide range of specialized cables crucial for monitoring, control, and communication throughout the pipeline's operational life.

For instance, fiber optic cables are indispensable for real-time data transmission, enabling immediate monitoring of pressure, temperature, and flow rates along the pipeline. This allows operators to detect anomalies swiftly and react to potential issues, ensuring both efficiency and safety. These cables, often buried alongside the pipeline, must be robust and resistant to environmental factors like moisture, temperature fluctuations, and rodent damage. Their high bandwidth capacity is essential for transmitting large volumes of sensor data and for facilitating remote control operations from a central command center.

Furthermore, instrumentation cables connect various sensors and transducers to control systems, relaying vital operational parameters. These cables must be shielded to prevent electromagnetic interference (EMI) that could corrupt data, especially in environments with heavy electrical equipment. Control cables, on the other hand, transmit signals from control units to actuators, valves, and pumps, enabling precise management of gas flow and pressure. These often require specific fire-resistant and low-smoke zero-halogen (LSZH) properties to ensure safety in enclosed spaces or emergency situations.

Finally, power cables are necessary to supply electricity to remote monitoring stations, cathodic protection systems (which prevent pipeline corrosion), and various equipment along the pipeline's route. These cables are engineered to withstand high voltages and currents, often requiring specialized insulation materials to prevent energy loss and ensure long-term reliability in harsh environments. The integrity of these cable systems is paramount, as any failure could lead to significant operational disruptions, safety hazards, or environmental incidents. The selection and installation of appropriate cable types, considering factors like voltage, current, environmental conditions, and signal integrity, are therefore critical aspects of pipeline engineering.

Phased Development and Strategic Importance

The pipeline construction will proceed in two distinct stages. The initial phase will see natural gas transported approximately 765 miles from the North Slope to the Anchorage region. The second stage involves the addition of compression equipment and approximately 42 miles of pipeline beneath the Cook Inlet, connecting to the Alaska LNG export facility in Nikiski. This facility will be constructed concurrently with the subsea pipeline section.

"Recent developments in the Middle East once again underscore the critical need for Alaska LNG, which originates from a secure, stable, and abundant source without transiting through potentially contested waters," commented Brendan Duval, CEO and Founder of Glenfarne. He further emphasized, "This agreement with PTT symbolizes the tremendous momentum of Alaska LNG, firmly putting it on track to become a reality that will address Alaska's natural gas deficit while simultaneously generating employment, business opportunities, and fostering increased economic development for Alaskan residents, businesses, and military installations."

Glenfarne joined the Alaska LNG project as a private partner in January 2025, a crucial step that propelled the project forward after a decade of design and permitting efforts. Just two months later, the U.S. company acquired the 75% interest held by Alaska Gasline Development Corporation (AGDC) in 8 Star Alaska, a subsidiary established to manage all Alaska LNG project assets. This acquisition positioned Glenfarne as the project's lead developer.

A significant milestone was achieved last month when Glenfarne tasked Worley with completing the final engineering for the pipeline segment of the project. Following the launch of its strategic partner selection process in early May 2025, aimed at identifying long-term collaborators for the LNG project, over 50 companies formally expressed interest, signifying more than $115 billion in potential contract value across various work packages.

Glenfarne continues to advance its strategic partner process for Alaska LNG, actively pursuing collaborations related to equipment and material supply, services, investment, and customer agreements.
