Abstract: The present invention provides a carbon dioxide ocean liquid balloon storage method. The method comprises: suspending an uncharged liquid balloon device in seawater at a depth of not less than 600 m in advance; conveying liquid carbon dioxide to an inside of the liquid balloon device through a conveying pipe; when the liquid carbon dioxide charging volume reaches the rated charging volume of a carbon dioxide submarine storage device, stopping charging; closing a stop valve of a liquid balloon inlet pipe and disconnecting the carbon dioxide conveying pipe from the liquid balloon inlet pipe; and controlling the liquid balloon device to enable the liquid balloon device to be placed in a seabed at the appropriate depth, with the depth of the seabed of not less than 3,000 m. The whole liquid balloon device is of a frame liquid balloon structure, and comprises a frame structure and a liquid balloon structure.
