We can make & deliver LNG much more efficiently in Alaska than anywhere else, for several reasons.
Our Cold Advantage is the first reason that comes to mind.
Leveraging an average annual air temperature that's 40F colder in Fairbanks than in Perth is just one thermodynamic factor. We can also save 99% of the excess heat generated by the 30% liquefaction penalty, by banking that clean heat underground beneath the city, improving the local climate and helping to clean the sulfolane out of the groundwater.

Alaska can also use Barclay's Cryo-LNG system providing much higher cryo-efficiency, for both the big LNG plants and little cryo-boosters along the delivery chain.

Alaska also has Boeing in their backpocket, very few people know about the tremendous amount of research and development that has been done at the Lazy-B since the 1960's on using LNG cryofuel for aircraft. Alaska can deliver LNG to premium global markets at 240mph getting thrice the price as marine-bulk shipping.
