Skyrocketing price of crude oil occurring in the last year strongly indicates the necessity of broader energy sources to ensure the stable supply of energy, especially liquid fuels. Synthetic liquid fuel for the transportation has been recognized critical again. The present report summarizes first the policies for deployment of the synthetic liquid fuels including Fischer-Tropsh oil, methanol and dimethyl ether in the major countries. Process and technology for the synthesis of liquid fuels from fossil resources called as gas to liquid (GTL) and coal to liquid (CTL) are introduced and their current statuses are reviewed. Some difficulties in their processes are analyzed. The current projects prosecuted in the world, mostly in China and US, are located in the maps. The coal gasification and methane reforming in the large scale to meet the quantity and price of synthetic fuels are the key technologies in this purpose for their positions in the real market. Japanese development in this area is briefly overviewed to give the current and future tasks. Influences of CO_2 regulation are also commented since the use of fossil sources must be strongly influenced by the regulation.
