Excavation of methane hydrate using COIL

摘要

Methane hydrate is a energy resource distributed even in the resource-less countries such as Japan and India. The energy is necessary to extract the methane from the methane hydrate and COIL is the unique solution for the extraction tool, because fuels of COIL can be produced from the natural energy without the fossil energy resources. The experimental results of laser light-methane hydrate interaction, multi kW laser light transmission through 1 km optical fiber, and the estimation of the extracted methane by radiation of the multi hundreds kW COIL output on the methane hydrate layer, will be reported.
