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

Abstract

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. The method includes: establishing a high-spatial-resolution Emissions grid database; according to pre-set screening conditions, in a specific area in a certain region, multiple sources of carbon dioxide capture, utilization and storage projects that meet the screening conditions are obtained; for the selected sources that meet the screening conditions Grid B i , conduct a spatial search within the search range formed by the specified distance D as the radius, and use the suitable storage sites and existing storage projects within the search range as the source grid B i sinks; for each grid that meets the screening criteria, match the sources of CO2 capture, utilization and storage projects with the sinks of carbon dioxide capture, utilization and storage projects to obtain multiple source-sink combinations; The source-sink combination is evaluated to obtain the 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.
