Capital costs of gas liquefaction are 40-50 % lower compared to 10 years ago in terms of thermal value thanks to technology breakthroughs and economy of scale. The costs of new LNG ships for a size of 135,000 m3 are reported as less than 200 million dollars while they used to be over 300 million. A statement that LNG is more economical at a distance longer than say 4,000 km seems no more true. The author has assessed the economic costs of LNG and pipelines simultaneously, by looking into the costs of gas field, liquefaction, shipping and regasification as well as pipelines. Conclusions show, for example, that LNG may be more economical at less than 2,000 km considering recent costs. LNG is competitive especially when security considerations require a pipeline to be planned for a parallel loop. Energy stock function of an LNG receiving terminal is also a plus in gas importing countries which often may lack old gas fields for changing into gas storage.
