Abstract
Abstract Methods, based on spatial analysis of the different criteria to be taken into consideration for building scenarios of CO2 Capture and Storage (CCS), have been developed and applied to real case studies in the Hebei Province (northeast China). The total CO2 emissions from point sources in the province amount to 220Mt/y, mainly from power plants, and from iron-steel, cement, ammonia plants, and refineries. Storage opportunities can be found in the Bohai Basin, characterised by a strong tectonic subsidence during the Tertiary, with several kilometres of accumulated clastic sediments. Two complementary methods were designed to best match sources and sinks, accounting for the cost of transport, injection and storage: an algorithm working on pairs of sources and sinks, and a spatial analyse on costs grids using functions of ArcGIS software which takes into account the additional costs of pipeline construction due to landform and land use.
