ABSTRACT

In this report, we report on hydrogen transportation using a communications infrastructure to achieve a decarbonized society.Due to a reduction in communication cable diameter, the space in the conduit to accommodate the cables has increased.To make effective use of this space, efforts are being made to transport hydrogen by using a double pipeline system.At present, the transportation of hydrogen is mainly carried out by tanker trucks, and further reduction of transportation costs and CO2 emissions are required in the future.As a solution, transporting by pipeline utilizing existing transmission lines is demonstrated.Hydrogen transportation by pipeline requires airtight transportation, because it is assumed that the gas is supplied under high pressure.Therefore, in the verification, a flexible stainless steel tube will be constructed in an existing communication tube and used as a pipeline for hydrogen transportation.
