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, in this paper the summary of results of carbonate loop technology analyses in oxyfuel regime from environmental aspect by the Life Cycle Assessment (LCA) method with two main methodologies CML and ReCiPe is analysed. Two general scenarios were considered for evaluation – 250MWe Czech power unit based on brown coal combustion with (Scenario 1) and without carbonate loop (Scenario 2). Scenario 2 was further divided in three subscenarios for different source of energy for carbonate loop operation. Sub-scenario 2.1 analyses power unit with carbonate loop heated by combustion of brown coal, scenario 2.2 analyses power unit with carbonate loop heated by natural gas and scenario 2.3 analyses power unit with carbonate loop heated by brown coal and waste thermal energy is utilized for further heating of carbonate loop. 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 levels, ozone formation potential 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 the most optimistic scenario for scenario 2.3 and the most pessimistic for scenario 2.1. Mentioned 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 main source of energy in the energy mix for the Czech Republic.
