Possible Source-sink Matching for CO2 Sequestration in Eastern India

AbstractIn India, the current CO2 emission level is 2,069 Mt with many large point sources emitting more than 10 Mt per year of CO2. Also, there are large numbers of coal-fired power plants emitting huge quantum of CO2. The potential sites for storage of captured CO2 from these stations are however limited by the geological and geographical features of the country. In Eastern India, such possible sites are few. On the other hand there already exist thermal power plants and there are 4 UMPP (Ultra Mega Power Plants) in the pipeline. It is with this background that an attempt has been made to analyze the source-sink scenario of CO2 emissions in Eastern India.Present paper focussed on the analysis of LP based approach of CO2 source-sink matching has been presented. CO2 emissions from the thermal power plants in the region of UP, Bihar, and West Bengal (Eastern Indian states) and potential sites at Talcher Coalfield, IB Valley Coal Field, Krishna-Godavari Basin and Eastern Coalfields (Birbhum coal Field) are considered for source-sink matching. The spatial analysis is carried out on a GIS platform using ArcGIS 9.3 particularly for route plan of the pipelines. The behaviour of sequestration site, particularly the storage capacity is a diminishing function. The source-sink matching is carried out considering the remaining capacity and available sources at shortest distance
