Life Cycle Assessment of calcium carbonate loop CO2 capture technology for brown coal power plant unit of the Czech Republic

Popis výsledku v původním jazyce

The carbon capture technology is the new concept for cleaner energy production in the Czech Republic. In order to comply with sustainability requirements, this paper summarizes the analysis of carbonate loop technology (CaO looping) from environmental aspect by the Life Cycle Assessment (LCA) method by two main methodologies CML and ReCiPe. Two general scenarios were considered for evaluation - 250MWe Czech power unit based on brown coal combustion without (Scenario 1) and with carbonate loop (Scenario 2). Scenario 2 is further divided in three sub-scenarios with different source of energy for carbonate loop operation. LCA study was performed in different evaluation stages of characterization level, normalization level and pareto analyses of identifying the most significant environmental categories. Results are showing the significant reduction in scenario 2 in environmental categories of acidiphication, ozone formation and global warming potential. On the other hand, scenario 1 results in better values for abiotic depletion levels. Sub-scenarios of scenario 2 are showing, that the most optimistic is scenario 2.3 manifesting utilization of steam from carbonation process as the energy source. The most pessimistic is scenario 2.1 focusing on combustion of brown coal and no further utilization of energy from carbonation process. Environmental impacts are connected with the processes of brown coal mining and processing and with the subsequent thermal energy production. Thus, suggested scenarios are focused on the elimination of the impacts connected with mentioned processes even though brown coal is the primary source of energy in the energy mix of the Czech Republic.
