Insulation Materials

In the European Union, almost 40% of all energy consumption comes from buildings, while another 20–25% comes from transport. In the European Union, including Hungary, only buildings with almost-zero energy demand could be built after 2020, and the use of renewable energies must be strengthened. The Renewable Directive stipulated that by 2020, the share of renewable energy in buildings must be 25%, and in transport it must be 10%; the use of electric vehicles is vital. There are about four million dwellings in Hungary, of which approximately three million need to be renovated, and only some of these (a few hundred) meet the cost-optimized level of the 2020 directive. The use of insulation materials is very important in the transport sector, too. Insulation materials are also used by aircraft and electric vehicles. To reduce the energy loss from buildings, different insulation materials can be used; investigations of insulation materials are very important. This paper presents a comprehensive research report on insulation materials which could be used for building elements, HVAC (heating, ventilation, and air conditioning appliances) equipment, and vehicles. In this paper, laboratory investigations will be presented along with calculations to better understand the properties and behavior of these materials. For this, firstly structural analysis with scanning electron microscope will be presented. Moreover, the paper will present thermal conductivity and combustion heat measurement results. The sorption and hydrophobic behavior of the materials will be also revealed. Finally, the article will also display differential scanning calorimetry measurements and Raman spectroscopy results of the samples. The research was conducted on four different types of colorized microfiber lightweight wool insulation.

This paper focuses on the process of convergence in per capita CO2 emissions that would occur if the measures taken by the European Union to meet the Kyoto Protocol commitments had been effective. We apply a time series and cross-sectional analysis to test for the existence of convergence among countries and for different economic sectors. The sample covers data for the 28 member countries from 1960 to 2012. The results show weak absolute convergence across countries but clear evidence of conditional convergence, with GDP, the weight of industrial sector and the use of renewable energies being the main drivers of divergence. Concerning sectors, there is an increase of emissions in the agricultural sector, but a reduction in the industrial and energy sectors. Different patterns arise in the energy subsectors where manufacturing and electricity notably reduced their emissions while the transport sector increased them in all countries.

In the members states of the European Union, portion of buildings in the total consumption of energy represents 40%, and their portion in CO2 emissions fluctuates around 35%. The European Union is trying to protect the environment by reducing energy demand and releasing CO2 emissions into the air. Energy performance is the quantity of energy, which is necessary for heating and domestic hot water production, for cooling and ventilation and for lighting. Based on results of energy performance, individual buildings are classified into energy classes A to G. A global indicator (primary energy) is the decisive factor for final evaluation of the building. The new building must meet minimum requirements for energy performance, i.e. it must be classified to energy class A1 since 2016, and to energy class A0 since 2020. The paper analyses effect of the use of different resources of heat in a family house designed according to requirements valid since 2020, and its subsequent classification into an energy class.

This paper explores the factors affecting the uptake of hybrid and electric vehicles in the European Union (EU) using data from two extensive cross-sectional surveys. Each survey consists of 26,500 responses to a questionnaire that combines socio-economic and behavioral aspects. The share of respondents across the EU stating that they would certainly or probably consider purchasing a hybrid or a battery-powered electric vehicle (H&EV) in the near future rose from 32% in 2014 to 37.4% in 2018. There is, however, a high variability among EU member states, as well as across different socio-economic groups. Propensity is highly correlated with income, educational attainment, and urbanization level. In order to address the high degree of collinearity, we applied a machine learning classification model to analyze and explain the interaction between the variables that affected the expressed propensity to purchase such a vehicle. The findings highlight something largely missing from the literature, namely that local conditions and regional variation are a major, if not decisive, factor regarding purchasing choices. Seen from a policy perspective, this conclusion may provide guidance regarding how to support the take up of H&EVs through measures that are tailored to the specific needs at the local level.

Progressive changes, dynamic business environment become a constant of life in several economics spheres, including the Lithuanian freight transport service sector. Lithuanian freight transport services are characterized as sector acting on the terms of high rivalry. The aim of this article is to analyse the competitiveness of the Lithuanian freight transport sector in the context of the European Union. The competitive theoretical background, estimation of competitiveness of freight transport services are analysed. The competitive analysis of the sector through the Porter’s model of five forces and internal characteristics of the enterprise defining the Lithuanian freight transport sector in terms of size and specialization is carried out. The methods of the research are systematics and a comparative analysis of scientific literature, quantitative research based on freight transport organisation survey. An empirical survey in which 349 freight transport service enterprises were examined allowed to reveal and estimate the most important factors influencing the competition intensity and the main firm-level factors that influence the companies’ competitiveness in the economic sector.

Theoretical Considerations

The paper focuses on potential effects of the ageing of the population on consumption expenditures of private households in the field of transport. Theoretical considerations as well as previous empirical results suggest that older households consume different goods and services than younger ones due to changing preferences and needs by increasing age. Possible consequences of these changes for goods and services in the transport sector are in focus. The expenditures of European households on transport based on the national household budget surveys of the 28 member countries of the European Union are analysed. The results suggest that expenditures in transport decrease at retirement age in all considered countries. Moreover, the structure of goods and services consumed in the transport sector changes over the life cycle of a private household, with implications for the public sector due to the ageing of the population to be expected.

Fuel Cell Hybrid

The transport sector is today a major source of pollutant and greenhouse gas emissions. Fuel Cell Hybrid Electric Vehicles are a solution to reduce its environmental impact, thanks to the zero pollutant tailpipe emissions and longer driving ranges if compared with full electric vehicles. A Digital Twin of a FCHEV is developed in this study, through the assessment of models of mechanical and thermal systems within the vehicle. The Simulink/Simscape model here presented is able to support both the design choices and the test of control strategies. The results obtained allow characterizing the impact of the auxiliary systems on the driving range, whose relative value ranges from 28% to 40% of the overall energy demand depending on the ambient temperature, and the range is between 430 km and 356 km respectively for mild and cold temperature.

Purpose of the work is to analyze the perspective directions for the development of transport biofuels sector in Ukraine. Current state and prospects for the production and utilization of transport biofuels in the EU are presented. It is shown that the consumption of transport biofuels in the European Union increased quite dynamically during 2004-2012, experienced a stagnation period for the next four years and started to rise again from 2017. Directive (EU) 2018/2001 (RED II) sets the mandatory target of achieving 14% of renewable energy in the EU transport sector by 2030, with a mandatory share of second generation biofuels. Analysis of the situation in Ukraine shows that the production of bioethanol and biodiesel, unfortunately, has not reached wide development. Over the past twenty years, several relevant programs were developed and approved in the country, but their implementation was not successful in terms of achieving the goals. Today, there are about 20 bioethanol producers in Ukraine with a total capacity of more than 300 kt/yr, but only 8 enterprises with a total capacity of 128 kt/yr are operating. It is known that 14 biodiesel plants with a total capacity of 300 kt/yr have been built in Ukraine, but at present they are actually idle. In addition, there are about 50 smaller enterprises capable of producing up to 25 kt of biodiesel per year, but no reliable information on the actual activity of these enterprises is available. It is obvious that the sector of transport biofuels is currently in a state of stagnation in Ukraine. To improve the situation, it is necessary to implement the consistent state policy and appropriate incentive instruments.

One important goal of the climate commitment in the European Union (EU) is to reduce primary energy demand in the transport sector and increase the use of renewables, since around 33% of primary energy is consumed in this sector. Therefore, the EU ordered its member states to raise the number of electric vehicles (EVs) within Europe. Consequently, the energy demand for electricity will rise as a function of the number of EVs. To avoid local grid overload and guarantee a higher percentage of clean energy, EV charging stations can be supported by a combined system of grid-connected photovoltaic modules and battery storage. In this paper, the focus lies on the feasibility and economic aspects of such systems. To provide an overview of the different e-charging station combinations, a support tool was modelled and developed, making it possible to size and manage EVs charging stations with only a few input parameters. Thanks to its easy handling, the tool suits a wide spectrum of users. Due to enhanced optional settings, this tool is suitable for detailed input parameters for professionals as well. Input categories are basically divided into the photovoltaic (PV) system, battery storage, the charging station itself, and investment analysis. The tool supports decisions for solar charging stations designed for different parking locations like offices, schools, and public and private places.

The widespread adoption of plug-in electric vehicles (PEVs) will depend on public appreciation of the potential savings in ownership costs that PEVs offer over conventional, internal combustion energy vehicles (ICEVs) and hybrid electric vehicles (HEVs), including fuel savings. This study compares the energy consumption and estimated ownership costs of various technologies for multiple drive cycles in the United States and the European Union; identifies and quantifies the impacts of the main parameters influencing the ownership costs of PEVs in comparison with other powertrains for different timeframes, vehicle classes, and technologies; and assesses under what combinations of parameters the cost of PEVs can be competitive with other powertrains.
