laska reached a long-awaited milestone with the arrival of the first shipment of liquefied natural gas (LNG) from the North Slope to the Interior in October 2025. The delivery demonstrated at last that North Slope gas can be consistently transported to Alaskan consumers.

For years, the challenge was not resource availability, as the North Slope gas fields hold some of the nation’s largest proven reserves. Instead, the challenge was getting that gas to the market. Harsh conditions, complex engineering requirements, and the high cost of pipeline development repeatedly stalled progress. The 2025 shipment signaled a breakthrough, built not on a megaproject pipeline but on a practical, scalable system designed to serve Alaskans first. The milestone proved that a truck-delivered LNG supply chain can reliably serve Alaska’s Interior.

“For the first time in history, North Slope gas isn’t just staying on the Slope—it’s reaching beyond to power Alaska’s future,” says Jason Rebrook, CEO of Harvest Midstream, the pipeline affiliate of Texas-based oil producer Hilcorp. “This project unlocks clean, reliable energy for Interior families and businesses and shows what’s possible when we work together to build Alaska’s energy security.”

The LNG project is possible thanks to new infrastructure at both ends of the supply chain. On the North Slope, Harvest built a small-scale liquefaction plant near Deadhorse where natural gas extracted as a byproduct of oil production is chilled to approximately -260°F. This reduces its volume enough to transport the LNG over long distances. Once liquefied, the LNG is loaded into specialized tanker trailers. Each tanker is designed to carry roughly 14,000 gallons and is built to maintain cryogenic temperatures throughout the 500-mile journey down the Dalton Highway.

Upon arrival at the Interior, Interior Gas Utility (IGU) stores the LNG in large, insulated tanks, then regasifies it and distributes it to homes and businesses across Fairbanks, North Pole, and nearby communities. The Harvest facility near Deadhorse can produce up to 150,000 gallons of LNG per day, which is roughly triple the capacity of IGU’s older plant at Point MacKenzie.

Harvest’s LNG plant entered its commissioning phase with the first arrival in the Interior. This stage involved thorough testing and validation of systems, equipment, and tanker-loading procedures prior to starting full-scale commercial operations. Upon Harvest reaching full operational status, IGU began receiving three to four tanker deliveries per week.

The process of liquefying on the North Slope, transporting LNG south using purpose-built vehicles, and subsequently distributing it throughout the Interior sidestep the upfront costs of building a new pipeline or a large export terminal. Small-scale liquification plus trucking offers flexibility, and the decision to build a small, modular facility with the capacity to expand gives Harvest and IGU room to ramp up capacity as demand increases.

Moving LNG by truck is an ongoing, well-coordinated process overseen by Middle Fork Logistics in Fairbanks. This approach ensures that North Slope LNG can be delivered to Interior communities year-round, even in challenging weather and road conditions.

The truck route used to deliver LNG to the Interior used to be shorter and more well-traveled: the Parks Highway from IGU’s original liquefaction facility at Point MacKenzie on Cook Inlet. The Fairbanks North Star Borough-owned company opted not to expand the facility, however, when Hilcorp reported it would be unable to fulfill an extended supply contract. That led the utility to pivot northward.

To secure a long-term, stable supply of natural gas, IGU signed a manufacturing agreement in 2023 with Harvest Alaska. The agreement spans an initial twenty-year term and includes options to extend the contract twice, each for an additional five years. According to IGU, this long-range partnership provides certainty for future planning, supports continued system expansion, and underpins IGU’s mission to deliver dependable, lower-cost energy to the Fairbanks North Star Borough for decades to come.

The utility serves more than 3,400 residential, commercial, and public-sector customers, helping reduce reliance on higher-emission heating fuels while improving air quality in the region. IGU operates an extensive distribution network with more than 150 miles of mainline piping in Fairbanks and an additional 85 miles in North Pole. This infrastructure is supported by 5.5 million gallons of LNG storage capacity across three sites, allowing the utility to manage seasonal demand swings and maintain reliable service during Interior Alaska’s long, cold winters.

While IGU converts buildings to accept North Slope gas, the borough is moving forward with developing a use-case for natural gas in transportation. In December, the Federal Transit Administration awarded a $3.1 million grant to phase in a bus fleet powered by compressed natural gas (CNG).

The Fairbanks North Star Borough Assembly voted in 2019 to convert the diesel-powered buses and gasoline-powered vans of the Metropolitan Area Commuter System into CNG vehicles. The timeline has stretched longer than anticipated, but CNG buses are rolling now. They began running routes last spring.

Also last spring, the borough assembly authorized the purchase of five more CNG buses for about $4.3 million, funded through previous federal grants. Those vehicles could arrive by the fall, allowing the transit system to retire some of its older stock. The fleet runs thirteen diesel buses and two vans.

To refuel the new vehicles, the transit system opened a $30 million maintenance station in 2024 equipped to handle CNG. For a second site, Fairbanks Area Surface Transportation Planning directed about $2.7 million from the federal Congestion and Air Quality program to build a CNG station at the UAF campus. The funding would also pay for the purchase of CNG for three years, until 2030.

The hope is that North Slope gas will replace refined petroleum, stabilizing Interior energy prices and helping to reduce air pollution in the region.

For decades, Fairbanks has struggled with some of the worst winter air quality in the nation. Temperature inversions trap pollutants near the ground, while emissions from wood-burning stoves, oil-fired furnaces, and older heating systems accumulate over weeks and months of freezing temperatures. The result has been elevated levels of fine particulate matter (PM2.5), which can aggravate asthma, trigger heart and lung diseases, and pose serious risks to children and seniors. Cleaner-burning energy sources have long been identified as essential to breaking this cycle.

With the successful transfer of LNG from the North Slope to the Interior, a practical solution to Fairbanks’ air quality woes arrived. When natural gas replaces coal, heating oil, or wood, it burns cleaner, producing fewer particulates and lower overall emissions. Each home or building that converts to natural gas for heating helps reduce the dense smoke that lingers during long, cold winters. Scaled across neighborhoods, public facilities, and schools, those reductions add up to meaningful improvements in winter air quality.

Although the positive impacts on local communities are significant, bringing LNG to the Interior represents an even greater achievement. It demonstrates a viable pathway to monetize gas that has remained stranded for generations. This approach to phased LNG development not only helps secure energy supplies for the Interior but also creates new job opportunities, investments, economic progress, and future phases of development. Most importantly, for the first time, Alaskans see evidence that the state’s plentiful gas can actually reach those it was always meant to serve.
