Environmental damage assessment of carbon capture and storage : Application of end-point indicators

摘要: Carbon capture and storage (CCS) is the most viable option to reduce CO2 emissions from power plants while continuing use of fossil fuels required satisfy increasing energy demand. However, CCS an intensive process, demands additional energy, chemicals infrastructure. The processes may also have certain direct air (NH3, aldehydes, solvent vapor etc.) generate solid wastes degradation byproducts. A trade-off in environmental impacts expected, with large-scale application needed make any significant reduction CO emissions, these potential trade-offs can become enormous magnitude. Therefore a systematic process evaluation complete life cycle for all available options deployment scenarios needed. Life Cycle Assessment (LCA) methodology wellestablished best suited such analysis. Methodology hybrid assessment used this work methodological developments are made build-up simple approaches future systems scenarios. thesis extends result presentation more comprehensible damage indicators evaluates control potentials human health, ecosystem resource depletion technology. results study shows that achieve global warming impact but multiple depending on These mainly due penalty infrastructure development waste treatment processes. Damage greatly health by mitigating climate change consumption. Scenario show clear advantage integration over Baseline scenario having significantly lower scores categories fossil-based electricity production. This thus illustrates novel technology, its overall benefits damages, implications large scale application.
