Ocean system carbon neutralization method

Abstract

The invention discloses an ocean system carbon neutralization method. A seaweed culture area is arranged on the sea surface; a burying robot and a capturing robot are arranged in the ocean; the capturing robot captures seaweeds in the seaweed culture area and then throws the captured seaweeds to the seabed; the burying robot is used for burying the seaweeds thrown by the capturing robot below the seabed at the seabed, so that the seaweeds are in an anoxic environment. Seaweed cultivation is carried out in the seaweed culture area, light above the sea surface permeates seawater to irradiate the seaweeds, so that water-soluble carbon dioxide is converted into organic matters by the seaweeds to grow and proliferate, inorganic carbon is transferred into the seaweeds from the seawater and exists in the form of organic carbon, and thus carbon in the sea is enriched to the seaweed culture area. The capturing robot captures and collects the seaweed in the seaweed culture area and puts the seaweed into the seabed, the burying robot buries the seaweed, organic carbon in the seaweed is transferred to the position below the seabed, and therefore the carbon in the seaweed is separated from ocean carbon circulation, and the purpose of carbon neutralization is achieved.

Description

technical field [0001] The invention relates to a carbon neutralization method for an ocean system, which belongs to the field of carbon neutrality. Background technique [0002] Carbon dioxide emissions lead to an unbalanced state of the earth's carbon cycle, and the trend of global warming is becoming more and more obvious. And carbon neutrality is an important means to solve this problem. [0003] There are two main approaches to carbon neutrality, one is to reduce carbon emissions, and the other is to capture and store existing carbon dioxide. For the second method, the most popular international method is to transport the carbon dioxide captured in the atmosphere to a designated storage location in the ocean through pipelines or ships, and then inject it into the ocean water body, the seabed or the geological structure below the seabed middle. In this storage method, if it is injected into a water body, the carbon dioxide will cause local ocean acidification when it ...

Problems solved by technology

[0004] In any of the above methods, personnel are required to work at sea for a long time, so the labor cost is high, and there are many uncertain factors in the sea environment, which has great potential safety hazards
