Abstract
A filter () is provided at a tip portion of an injection well (). A pumping apparatus () pumps carbon dioxide stored in a carbon dioxide tank (). The pumping apparatus () feeds carbon dioxide from the carbon dioxide tank () into the injection well () by means of a pump. In the pumping apparatus, the pressure and temperature of carbon dioxide are maintained at respective predetermined levels or higher by means of a pressure regulation valve, a temperature regulator, etc., whereby carbon dioxide enters a supercritical state. The carbon dioxide having entered a supercritical state is fed in the direction of arrow A through the injection well (), passes through the filter () provided at an end portion of the injection well (), and is injected into a brine aquifer (). Carbon dioxide injected into the brine aquifer () assumes the form of microbubbles.
