Opis:: Vehicle exhaust emissions depend on multiple factors, such as the emission norm, driving parameters (speed, acceleration) or the technical condition of the vehicle. These driving parameters may often depend on the condition of the road infrastructure and other factors influencing road conditions. The article attempted to assess the emissivity during acceleration of a vehicle powered by a compression ignition engine. Mapping the actual values is possible with the use of exhaust emission measurement equipment that operates under the actual operating conditions of a vehicle. Recently, an increase in the use of simulation methods in research of this type has been observed. The authors decided to check the suitability of using road traffic simulation software to estimate the $CO_2$ emissions during vehicle acceleration. The obtained results are promising, because in terms of the emissions of the analyzed exhaust gas component, the simulation results differed from the results obtained during measurements with the use of Portable Emissions Measurement System (PEMS) equipment by less than ±20%.

Opis:: A lot of attention is nowadays devoted to the problem of generally defined ecology. It is absolutely essential in case of systems and sources generating heat due to their direct influence on the environment through emitting post-process products to the atmosphere which are, most frequently a result of combustion. Therefore, constant searchers are made to optimize the operation of heat sources and to acquire energy from sources for which the general balance of carbon dioxide emission is zero or close to zero. This work compares the emissions of equivalent CO₂ from selected systems with the following heat sources: coal, gas furnace, heat pump, and refers results of the analysis to aspects connected with regulations concerning environmental protection. The systems generating thermal energy in the gas furnaces, coal, biomass, as well as the compression heat pumps with the lower heat source as ambient air or ground were taken under consideration, as well as centralized systems for the production of heat based on the combustion of coal, gas, oil, and biomass. the Emission of carbon dioxide for the installation of cogeneration and absorption heat pump were also calculated. Similarly obtained amount of extra emission necessary for the proper operation maintenance of heating devices via the supplied electricity from external source, the mostly fuel-fired power plants for fuels as previously mentioned. The results of the calculations were presented in tables and graphs.

Tytuł:: Climate Change and its Effect on the Energy Production from Renewable Sources – A Case Study in Mediterranean Region

Opis:: In terms of climate forecasting, the Mediterranean region is among the most difficult. It is correlated with the five significant subtropical high pressure belts of the oceans and is symbolized by dry and hot summer and cold and rainy winter. Due to its location in the area, Albania is particularly susceptible to climatic changes. It has been noted that summertime sees the greatest temperature increases. More intense heat waves that stay longer and occur more frequently are anticipated in the eastern Mediterranean. The seasonal patterns of precipitation have not changed, but the amount of rain has become more intense. The effects of climate change have drawn attention to various renewable energy sources, including solar and wind power. In this study, the changes and prospective in average temperature, rainfall, humidity, CO2 emission and their impact in energy production were investigated. Several different models such as Auto Regressive Integrated Moving Average method; Prophet algorithm; Elastic-Net Regularized Generalized Linear Model; Random Forest Regression models; Prophet Boost algorithm; have been built for the study and prediction of each variable. The appropriate models are used to determine the anticipated values of the indicators for a period of four years. The prediction shows an increase in CO2 emission which leads to a decrease in energy production by hydropower. These findings suggest the use of other renewable sources for energy production in the country and the Mediterranean region.

Tytuł:: Prospects of CCS Projects Implementation in Russia: Environmental Protection and Economic Opportunities

Opis:: The urgency of environmental protection is determined by its intensive change because of human impact, which, among other things, accompanied by an increasing of carbon dioxide (CO₂) emissions. One of the ways to reduce the emission is Carbon Capture and Storage (CCS) technologies. To date, developed countries have successfully implemented a number of CCS demonstration projects. Their main purpose is to study the effectiveness of CO₂ storage. Russia is one of the world’s largest producers of CO₂ emissions. However, CO₂ capture and storage issues are not studied by Russian enterprises due to the absence of environmental taxes. The experience of developed countries shows that CO₂ storage projects, in addition to the reduction of anthropogenic impact, can be commercially effective not only by reducing the tax burden. This review presents the analysis of international experience in the field of CO₂ capture and storage. Given the immaturity of technology and lack of the necessary volume of statistical data, it was an attempt to determine the minimum conditions, which permit the implementation of CCS projects in Russian oil fields. On the basis of the Russian development forecast and the fuel balance structure the volumes of CO₂ emissions in the 2016–2030 years were calculated. According to significant difference in opinions about the feasibility of CCS implementation in Russia, this review presents the main arguments for and against such projects. Evaluation of the potential effectiveness of CCS projects to enhance oil recovery factor showed that in spite of the absence of CO₂ emissions taxes, such projects could be commercially effective in Russia due to the increase in oil recovery.

Opis:: This study aims to analyze the forecasting of CO₂ emission from the energy consumption in the Rubber, Chemical and Petroleum Industries sectors in Thailand. The scope of research employed the input-output table of Thailand from the year 2000 to 2015. It was used to create the model of CO₂ emission, population, GDP growth and predict ten years and thirty years in advance. The model used was the VARIMAX Model which was divided into two models. The results show that from the first model by using which predicted the duration of ten years (2016–2025) by using VARIMAX Model (2,1,2), On average, Thailand has 17.65% higher quantity of CO₂ emission than the energy consumption sector (in 2025). The second model predicted the duration of 30 years (2016–2045) by using VARIMAX Model (2,1,3) shows that Thailand has average 39.68% higher quantity of CO₂ emission than the energy consumption sector (in 2025). From the analyses, it shows that Thailand has continuously higher quantity of CO₂ emission from the energy consumption. This negatively affects the environmental system and economical system of the country incessantly. This effect can lead to unsustainable development.

Opis:: The energy sector worldwide is a significant source of air pollutant emission. In Poland, the vast majority of heat and electricity is generated in coal-fired heat and power plants. There is a common belief that high greenhouse gas emissions from the energy sector in Poland are mainly due to the technological processes involving the conversion of energy by burning fossil fuels. However, coal mining also causes a high environmental burden. This paper aimed to determine the carbon footprint of a typical hard coal-fired heating plant in Poland, taking into account mining of hard coal, its transport to the heating plant and useful energy generation in the heating plant. The investigation carried out allowed comparing the process steps and determining which of them is the dominant source of the greenhouse gas emissions. The obtained results show that hard coal mining and hard coal transport account for almost 65% and 5% of total equivalent carbon dioxide emission, respectively. Energy transformations in the heating plant account for 30% of total equivalent carbon dioxide emission, where approx. 29% is due to hard coal burning and 1% due to electricity consumption. The relative shares of carbon dioxide, methane and nitrous oxide in total equivalent carbon dioxide emission account for approx. 91%, 4% and 5%, respectively.
