The first investments in Liquefied Natural Gas (LNG) technologies date back to the 1970s, but it is only in the last decade that a real globalisation of the gas market has been triggered due to the possibility of affordable sea transportation. In Asia, the large consuming countries (Japan and Korea) have invested heavily and pioneered the development of new technologies by creating a network for their own supply from the producing countries in Indonesia and Malaysia. China is also making large investments in infrastructure. It has to supply the energy needs of 20% of the world's population but has only 1.5% of the global oil resources, 3% of gas, and despite having 13% of the world's coal reserves, is trying to get away from it consistent with its own rate of development.
LNG offers clear benefits in terms of safety and flexibility. The gas market is no longer tied to the continuity and operation of fixed pipeline networks and recompression stations, which often cross countries and regions and come with potential geographic and political complexities. In addition, transport costs become relatively cheaper with distance instead of increasing rapidly with the length of the necessary route, offering higher marketability for producing countries and supply possibilities for consuming countries.
