Life cycle modelling of fossil fuel power generation with post-combustion CO2 capture

摘要: Abstract Due to its compatibility with the current energy infrastructures and potential reduce CO2 emissions significantly, capture geological storage is recognised as one of main options in portfolio greenhouse gas mitigation technologies being developed worldwide. The offer a number alternatives, which involve different consumption rates subsequent environmental impacts. While objective this technology minimise atmospheric emissions, it also important ensure that does not aggravate other concerns. This requires holistic system-wide assessment rather than focusing on gases only. Life Cycle Assessment meets criteria only tracks non-energy-related releases but various releases, such solid wastes, toxic substances common air pollutants, well resources, water, minerals land use. paper presents principles LCA model at Imperial College uses pulverised coal post-combustion example demonstrate methodology detail. At first, models for combustion system chemical absorption are presented together examples relevant applications. Next, two applied plant capture, order compare life cycle performance systems without capture. results alternative methods (including MEA, K+/PZ, KS-1) have shown that, compared plants can achieve approximately 80% reduction global warming significant increase impact categories. all solvent modelled, KS-1 performed best most
