“…The model-based result thus obtained was proposed as one of the key performance indicators (KPI) for bituminous coal mines, applicable to decision-making support processes (e.g., the investment decisions in mining enterprises). A combined methodology (i.e., a combination of LCA and TEC (Thermo-Ecological Cost) for the assessment of the fossil fuel extraction system in its energo-ecological aspects was also suggested in the study by Stanek W. et al [25]. In this case, the boundaries of the system have been extended to also include the TEC ratings for coal use technologies.…”

This paper presents a model combining the LCA (Life Cycle Assessment) of fossil fuel extraction with its quality parameters and related CO2, SO2 and dust emissions at the stage of the combustion process. The model which was developed aims to identify the environmental impact of the processes of electricity production from selected energy carriers over their whole life cycle. The model takes into account the full LCA of fossil fuel extraction (of both hard and brown coal), its enrichment and fuel production as well as the environmental impact associated with emissions introduced into the air at the stage of electricity generation based on the fuels evaluated. Such an approach allows one to determine the fuel quality parameters that affect the environmental impact of energy production based on an LCA of mining and assigns the degree of environmental impact involved in particular production processes. Overall, the results obtained based on the proposed model permit the identification and prioritisation of the individual processes in the electricity generation life cycle which contribute the highest share in the general environmental impact indicator, having taken into account the modelling of the quality of the fuels used (calorific value, ash and sulphur content).

The use of coal is suspected to have high environmental impact. Natural gas is treated as more environmentally friendly with high methane content and lower emission factors. In order to calculate the environmental impact in the whole life cycle associated with combustion of coal and natural gas all stages from "cradle to grave" should be taken into account. In particular, the transportation stage, especially in the case of life cycle analysis of gas, seems to be crucial. The distance of transmission of gas from gas fields, for instance located in Siberia, could be mainly associated with high diffuse emission of methane. The comparison of environmental impact assessment of coal and natural gas utilization for heating purposes is presented in the paper. The additional factor taken into account is localisation of boilers. In the analysis the coal is sombusted in combined heat and power plants equipped with flue gas treatment units is that released emissions are relatively remote from an urban area. In contrast, the natural gas is burned in small domestic installations with no additional FGT systems. The results of the analysis are given in 6 major impact categories. Moreover, the results of the life cycle analysis were brought into comprehensive thermo-ecological cost index, which is a cumulated exergy consumption of non-renewable resources. The results presented in the paper refer to the contemporary problem of the choice of energy sources in the context of its overall environmental efficiency.

“…In principle, the proposed framework allows to include all types of emissions. Particular attention is taken for CO 2 emission in this case study, for it contributes to the greenhouse effect, and it is emitted in large quantities by the industrial processes [6], and the quantitative correlation between steam (or electricity) and CO 2 is also available. Therefore, for the sake of simplicity, the requirement for CExCT is limited to the treatment of CO 2 in this paper.…”

The cumulative exergy method is used to analyze and optimize a heat pump distillation process with respect to the total environmental impact including resource use and emissions. The results from the proposed method are compared with the ones from thermoeconomics. It is found that such an extended exergy analysis offers a new insight and permits the identification of solutions which are more stable in time and independently of economic conditions.
