Abstract
An analysis was carried out of the carbon footprint (CF) of technology for hydrogen production by subbituminous coal and lignite gasification. The analysis covered entrained flow gasification technology: GE Energy/Texaco and Shell. For calculations, the configuration of the synthesis gas generation system was adopted based on technological solutions available on a commercial scale. Gasification of subbituminous coal using Shell technology gives a yield of 5.1 kg H2 GJ−1 of energy contained in coal. Using the GE/Texaco technology for gasification of subbituminous coal and Shell technology for lignite gasification, hydrogen yields were lower by 8 and 10%, respectively. The scope of the analysis included: mining, mechanical processing, and transport of coal to the gasification plant, as well as gasification and capture of CO2 and its sequestration. The process of sequestration decreased the CF by 69% for the GE/Texaco technology and 78% for the Shell technology. The CFs of producing 1 kg H2 with sequestration of carbon dioxide were as follows: 4.1 and 5.2 kg of CO2 for subbituminous coal gasification using the technology by Shell and Texaco, and 7.1 kg of CO2 for lignite gasification using Shell technology. The CF per 1 GJ of hydrogen produced in the gasification of subbituminous coal with sequestration of captured CO2 amounted to 34.5 and 43.4 kg of CO2 equivalent using the Shell and GE/Texaco technology. This was approximately 2.5 times lower than the CF of 1 GJ of coal. For 1 GJ of hydrogen produced from lignite gasified using Shell technology with sequestration of CO2, the CF was 59.5 kg of CO2, about 65% smaller than the CF of 1 GJ of energy in lignite. When the analyzed variations of hydrogen production did not include the sequestration of captured CO2, the CF of 1 GJ of hydrogen was from 76 to 124% higher compared with the corresponding indicator for coal.
