Carbon dioxide source-sink matching method and device based on emission grid

Abstract

The invention belongs to the technical field of greenhouse gas emission reduction spatialization, and particularly relates to a carbon dioxide source-sink matching method and device based on a high-spatial-resolution emission grid, and the method comprises the steps: building a high-spatial-resolution emission grid database of a certain region; according to a preset screening condition, in a specific area in a certain region, obtaining a plurality of sources of carbon dioxide capture, utilization and storage items meeting the screening condition; performing spatial search on the selected source grid Bi meeting the screening condition in a search range formed by taking a specified distance D as a radius, and taking a suitable storage site and an existing storage item in the search range as a sink of the source grid Bi; for each grid meeting the screening condition, matching the source of the carbon dioxide capture, utilization and sequestration project with the sink of the carbon dioxide capture, utilization and sequestration project to obtain a plurality of source-sink combinations; and evaluating each obtained source-sink combination to obtain an optimal source-sink combination.

Description

technical field [0001] The invention belongs to the technical field of spatialization of greenhouse gas emission reduction, and in particular relates to a carbon dioxide source-sink matching method and device based on a high spatial resolution emission grid. Background technique [0002] Global warming is undeniable and has already had significant impacts on natural and human systems, such as reduced food production, vegetation destruction, increased forest fires, increased losses from drought and flood disasters, and degradation of the ecological environment. The increase in greenhouse gas emissions caused by human activities is the main cause of climate change since the middle of the 20th century. Among them, carbon dioxide emissions from fossil fuel combustion and industrial processes accounted for about 78% of the total increase in greenhouse gas emissions from 1970 to 2010. Reducing carbon emissions is an important mitigation measure to address climate change. [0003]...

AI Technical Summary

Problems solved by technology

The theoretical geological storage capacity is huge, suitable for CO 2 The large-scale concentrated emission sources captured are numerous, widely distributed, and of various types, but the geological conditions are complex, the population is densely distributed, and the dislocation distribution pattern of sources from east to west increases the difficulty of large-scale utilization of carbon dioxide capture, utilization, and storage.

There are problems such as data inconsistency, incompleteness, unclear sources, and duplication of work in the existing source-sink assessment of carbon dioxide capture, utilization, and storage.
