Abstract
A carbon dioxide tank () is connected to a pump device (). The pump device () is joined and connected with an infusion well (), which is a tubular body. The infusion well () extends downward beneath the ground () and is provided so as to reach a saltwater aquifer (). Part of the infusion well () forms a horizontal well () in a substantially horizontal direction. In other words, the horizontal well () is a location in which part of the infusion well () is formed in a substantially horizontal direction within a saltwater aquifer (). The horizontal well () is provided with filters (), which are porous members. For the filters (), for example, a fired member in which ceramic particles are mixed with a binder that binds those particles can be used. Moreover, if the hole diameter for the filters () is small, microbubbles with a smaller diameter can be generated.
