The problems of LNG transportation over long distances by sea and rail, as well as by pipeline are examined. The opinion was advanced that currently the LNG railway transport advantages in Russia are substantially undervalued. Thus, transportation of 55 billion cubic meters (25 million tons) of natural gas per year (the power of the Nord Stream-2 project) would require the railways let pass additionally no more than 20 LNG train pairs per 24 hours. It corresponds to the throughput of only one single track railway. In reality, transportation of the additional 25 million tons of LNG by the railway would not require any radical railway infrastructure modernization. The authors estimated the cost of cryogenic containers-cisterns, required for 25 million tons of LNG transportation. It is three times less than the cost of “Nord Stream-2” pipeline laying. The article considers prospective areas for the LNG employing, primarily, for transport and as an aircraft fuel. It was demonstrated that transition to the LNG makes even rather old airliner, adapted to the LNG, economically beneficial. The prospects of creating hybrid energy systems when pumping LNG through cryogenic cooling channels of superconducting cables are discussed. The well-known methods for hydraulic resistance reduction of such cryogenic channels, allowing pumping LNG over considerable distances are described. The conclusion was made that adding thin fibers to the flow, as well as adding ice crystals to the liquid flow (cryogenic ice gruel) might be effective for the cryogenic temperatures. These additives are similar to the anti-turbulent admixtures used at higher temperatures. It is concluded that at cryogenic temperatures drag reducing agents usually used in petroleum pipelines cannot be used. A suggestion was made that pumping of LNG in the form of cryogenic gruel, containing ice needles with aspect ratio (l/d) within the range of 25-35 would be most effective.
