The energy sources and their utilizations seem to become diverse and make a continued shift from oil to natural gas. Technology developments to monetize natural gas such as CNG and NGH pursuing higher transportation efficiency and those of GTL, DME and GTW which transform from gas to other energy form have been progressed. Some of these options have achieved commercial applications. Floating LNG is also seriously studied to apply offshore gas development scheme. This paper describes features of these options and international trends of each technology.
