Analysis of Current Possibilities of CO 2 Storage in Coal Bed Methane Deposits in the Czech Part of the Upper Silesian Coal Basin (USCB) Based on Archival Data

Popis výsledku v původním jazyce

Geological storage of CO2 is the end of a CCS (Carbon Capture and Storage) technology chain, being one of the technologies to reduce greenhouse gas emissions formed in connection with fossil fuel combustion. Capture and storage of CO2 is considered one of the possible solutions to reduce CO2 emission produced by human activity and at the same time have secondary benefits from this activity, such as increasing the yield of some oil deposits. CO2 is mainly generated by burning fossil fuels in large combustion units such as coal power plants and smaller units such as cars, and local heating plants in residential and commercial buildings. Carbon dioxide emission is also a product of industrial activity and mining as well as deforestation to create new agricultural land (e.g. Brazil, etc.). Coal seams are a geological formation that offers another possibility of CO2. Underground storage of CO2 in coal seams is considered to be one of the competitive options. The method is labelled as Enhanced Coal Bed Methane (ECBM), and it is suitable for methane deposits bound onto deep coal seams, particularly those difficult to extract when more optimal seams are preferred for mining. Emission gas or concentrated CO2 is injected into coal seams through boreholes. At the same time, yield boreholes are used to recover methane which is subsequently used. This way, the cost of storage is lower. The capacity to create gas storage in a coal seam is given by the existence of a dual-pore coal system. The primary pore system is formed by micropores and meso pores, while the secondary system represents macro pores and cracks. The less permeable primary system contains the majority of gas, the transport of which is ensured by the secondary system through Darcy flow. When injecting CO2, sorption occurs in the primary pore system, and CH4 pressure falls in the secondary pore system at the same time. Based on available archival data, the analysis aimed to realistically estimate the storage capacity of CO2 in the Czech part of the Upper Silesian Basin.
