CCS scenarios optimization by spatial multi-criteria analysis: Application to multiple source sink matching in Hebei province

Abstract : A method, based on spatial analysis of the different criteria to be taken into consideration for building scenarios of CO2 capture and storage (CCS), has been developed and applied to real case studies in the Hebei province Totally 88 point sources (42 from power sector, 9 from iron and steel, 18 from cement. 16 from ammonia, and 3 from oil refinery) are estimated and their total emission amounts to 23 1 7 MtCO(2)/year with power, iron and steel. cement. ammonia and oil refinery sharing 59 13%, 25 03%. 11 44%. 3 5%, and 0 91%. respectively Storage opportunities can be found in Hebei province, characterised by a strong tectonic subsidence during the Tertiary, with several kilometres of accumulated clastic sediments Carbon storage potential for 25 hydrocarbon fields selected from the Huabei complex is estimated as 215 MtCO(2) with optimistic assumption that all recovered hydrocarbon could be replaced by all equivalent Volume of CO2 at reservoir conditions. Storage potential for aquifers in the Miocene Guantao formation is estimated as 747 MtCO(2) if closed aquifer assumed or 371 MtCO(2) if open aquifer and single highly permeable horizon assumed. Due to poor knowledge oil deep hydrogeology and to pressure increase in aquifer. injecting very high rates requested by the major CO2 sources (>10 MtCO(2)/year) is the main challenge, therefore piezometry and discharge Must be carefully controlled A source sink matching model using ArcGIS Software is designed to find the least-cost pathway and to estimate transport route and cost accounting for the additional costs of pipeline construction due to landform and land use Source sink matching results show that only 15-25% of the emissions estimated for the 88 sources can be sequestrated into the hydrocarbon fields and the aquifers if assuming sinks should be able to accommodate at least 15 years of the emissions of a given source
