“…Most LCA studies provided emission factors for NO x and SO 2 , ranging from 0.02-0.06 kg NO x /MWh and 0.02-0.04 kg SO 2 /MWh with emissions mainly depending on the electricity mix used for 13 manufacturing. When using IOA, emission factors of 0.11 kg NO x /MWh and 0.05 kg SO 2 /MWh were reported [47], which were higher than the previously mentioned emission factors estimated using PCA.…”

“…Life cycle emissions of GHG were reported in the range of 2-5 kg CO 2 -eq/MWh for run-of-river systems and 11-20 kg CO 2 -eq/MWh for dam-reservoirs. The highest emissions factors were found in a study using the IOA approach [47], again indicating that greater impacts are estimated when using IOA instead of PCA. An important aspect of hydropower with dam-reservoirs is methane emissions from the anaerobic decomposition of flooded organic matter.…”

“…Emissions of NO x and SO 2 were dominated by direct emissions for coal combustion, whereas fuel provision was more relevant for IGCC, due to the high efficiency and high removal via FGC and consequently lower emissions at the stack. For example, Nomura [47] and the DoE [48] reported emissions for coal provision contributing to more than half of the overall impacts for NO x and SO 2 , respectively for IGCC; infrastructure was always found to be negligible for all three compounds.…”

“…It should be noted, however, that such a study including electricity storage cannot be directly compared to a study of wind power without storage because of the different functional unit used (see the discussion later). Based on IOA, emission factors were estimated on the order of 30-40 kg CO 2 -eq/MWh [47], thus providing higher values than similar studies using PCA. Emission factors reported in previous review studies were in the range of 5-35 kg CO 2 -eq/MWh [3,4,8,15,[44][45][46]53,[58][59][60]68].…”

Electricity generation is a key contributor to global emissions of greenhouse gases (GHG), NO x and SO 2 and their related environmental impact. A critical review of 167 case studies involving the life cycle assessment (LCA) of electricity generation based on hard coal, lignite, natural gas, oil, nuclear, biomass, hydroelectric, solar photovoltaic (PV) and wind was carried out to identify ranges of emission data for GHG, NO x and SO 2 related to individual technologies. It was shown that GHG emissions could not be used as a single indicator to represent the environmental performance of a system or technology. Emission data were evaluated with respect to three life cycle phases (fuel provision, plant operation, and infrastructure). Direct emissions from plant operation represented the majority of the life cycle emissions for fossil fuel technologies, whereas fuel provision represented the largest contribution for biomass technologies (71% for GHG, 54% for NO x and 61% for SO 2 ) and nuclear power (60% for GHG, 82% for NO x and 92% for SO 2 ); infrastructures provided the highest impact for renewables. These data indicated that all three phases should be included for completeness and to avoid problem shifting. The most critical methodological aspects in relation to LCA studies were identified as follows: definition of the functional unit, the LCA method employed (e.g., IOA, PCA and hybrid), the emission allocation principle and/or system boundary expansion. The most important technological aspects were identified as follows: the energy recovery efficiency and the flue gas cleaning system for fossil fuel technologies; the electricity mix used during both the manufacturing and the construction phases for nuclear and renewable technologies; and the type, quality and origin of feedstock, as well as the amount and type of co-products, for biomass-based systems. This review demonstrates that the variability of existing LCA results for electricity generation can give rise to conflicting decisions regarding the environmental consequences of implementing new technologies.

Straipsnyje analizuojama kietojo biokuro, naudojamo Lietuvoje, būklė, plėtros galimy bės ir poveikis aplinkai bei indėlis į klimato kaitą. Nustatyta, kad kietojo biokuro poten cia las 2011 m. buvo 1 442 ktne ir jo panaudojimas šilumos sektoriuje siekė 50,8 %. Iki 2020 m. potencialas turėtų padidėti 14,6 % ir pasiekti 1 648 ktne, o kietojo biokuro potencialo panaudojimas šilumos sektoriuje turėtų išaugti iki 67 %. Įgyvendinus Lie tuvos strateginiuose dokumentuose numatytą kietojo biokuro naudojimo šilumos gamybai plėtrą, būtų sudaryta galimybė iki 2020 m. šalyje šiltnamio efektą sukeliančių dujų emisiją sumažinti 6 %. Pagrindinių orą teršiančių medžiagų emisija pakistų skirtingai. SO 2 , NO x ir KD emisijos sumažėtų atitinkamai 13,1, 3,2 ir 28,4 %, tačiau LOJ ir CO emisijos padidėtų atitinkamai 1,3 ir 8,2 %.
