Abstract:

CNT based material are of vital importance in modern technology for their superior physical and chemical properties. In recent times, materials development for energy applications is focused for improvement of battery, capacitors, and electrodes for enhanced efficiency. High performance Supercapacitors with high energy densities are at the leading edge for renewable energy engineering device sector. CNT based Ni-Co-O material is of keen interest due to its possible applications as supercapacitors, electrocatalyst for metal/air battery and others. The hybrid material synthesis, morphological and electrochemical features are vital to evaluate the material performances for energy applications. Electrical studies are also important to evaluate the properties required for device applications. CNT is used as electrode material for electrochemical storage due to superior chemical stability, low mass density, low resistivity and large surface area. CNT replaces activated carbon material as supercapacitor due to improper balance between enhanced surface area and mesoporosity thus limiting electrolytic accessibility and capacitance. In the present article a brief review is stressed forward for the development of CNT-Ni-Co-O based hybrid material for supercapacitor high energy density applications.

Abstract:

The perspective energy sources alternative to hydrocarbons, which are currently used in the world, are considered. Energy-saving technologies for the use of hydrocarbon fuel in vehicles are analyzed. The need to develop the use of electric drives on automobiles is noted. The importance of systematical accumulation and analyzing of the existing experience of operating vehicles with electric drives abroad and in the Russian Federation is considered. Monitoring the technologies developed abroad and the problems arising during the operation of electric vehicles will make it possible to determine the priority ways of their development and to concentrate the efforts of researchers in the direction ensuring the maximum efficiency of their application. One of the currently attractive and economically viable ways of developing road transport for domestic practice is the use of vehicles with hybrid power plants. It is shown that the production of hybrid vehicles and electric vehicles abroad is successfully developing and is nowadays one of the most dynamic in the world. Indicators of efficiency of electric power consumption of vehicles with electric drive of various automobile manufacturers are given. A comparative analysis of technologies for the use of electric automobiles to improve the environmental situation in megalopolises is carried out and the problems of increasing the efficiency of automobile power plants are considered. It is shown that the climatic conditions of the Russian Federation with long periods of low temperatures of atmospheric air strongly affect the energy losses associated with heating the passenger compartment, and to a large extent - on the energy efficiency of the power plant of electric vehicles. To assess the efficiency of using electric vehicles, it is proposed to use a universal indicator of the efficiency of energy consumption. It is proposed to carry out a comparative assessment of the energy consumption of various vehicles by the energy parameter qEL. The calculated data show that the use of vehicles with electric drive and, in particular, rechargeable hybrids is more profitable in comparison with the use of vehicles equipped exclusively with internal combustion engines.

Abstract:

Abstract The article deals with the problem of electric power production in terms of environmental impact, in particular the energy efficiency of its production to utilize primary sources. The efficiency of its production directly depends on the composition of primary sources and technologies used. Difference in efficiency by converting various forms of energy into electrical power and their ratio in the use directly affect the resulting efficiency, production of emissions and thus the environmental impact. Electric traction, its production, is burdened less efficient than other types of tractions used in transport, but at the final reconciliation of their consumption in vehicles, this difference decreases or delays because the vehicles themselves work with different conversion efficiency of its traction on mechanical work, vehicle driving.

Abstract:

The transport system of the Russian Federation includes not only railway, automobile, air, sea and river transport, but also main gas and oil pipelines. Given the volume and variety of modes of transport, the introduction of measures to improve energy efficiency in the transport sector will save significant amounts of fuel and energy resources. In the light of the annual increase in energy consumption, the degree of negative impact on the environment and the amount of emissions of harmful substances, energy saving issues in transport make this issue even more important. The article describes the dynamics of the Russian car market for the previous year, shows the key ways to improve energy efficiency and energy saving in road transport.

Abstract:

The present paper highlights a quantitative method to maximize energy efficiency based on the minimum energy consumption and maximum quality of life from consumption behaviors. Quality of life is expressed by utility, which is a Constant Elasticity of Substitution (CES) function of demands for composite goods, car trips and public transport trips. Individual energy consumption is estimated by the demand of goods and we applied this method to Nagasaki to evaluate energy efficiency. Our results showed that 28,154 kcal of energy is needed to support the life of one individual per day in Nagasaki. Furthermore, we found that 76% of energy was used for composite goods and 24% was used for mobility goods. To achieve maximum energy efficiency, our results highlight that energy should be reduced by increasing the consumption of composite goods and public transport trips, while simultaneously decreasing the consumption of car trips. Compared to residents in urban and suburban areas, individuals in Central Business Districts (CBD) were found to have higher energy efficiency. Findings in Nagasaki suggest three policy implications: First, eco-energy consumption patterns should be encouraged to decrease energy use, while maintaining quality of life. Second, mixed land use is attributed to increased energy efficiency. Lastly, the energy efficiency of mobility could be improved though increasing the attraction of public transport.

Abstract:

The main drivers of the electric cars diffusion which is projected in the next decade are to be seen in the industry effort to create new spaces in mature car markets (supply side), and in demand side effects of current climate mitigation policies in the transport sector, focused on CO2 emissions and energy efficiency of new vehicles sold. Indeed the energy performances of electric vehicles are projected to be highly variable; the final results of fleet average comparisons with internal combustion engines vehicles will be affected by at least: a) the real energy efficiency of the EV models (in particu- lar by their weight), b) the battery efficiency rate; c) the average energy losses of the national grids, and d) the national thermoelectric generation efficiency. For example, if sensitivity analysis on Germany or USA power plants efficiencies is undergone, EV primary energy consumptions result to be respectively +8% and +30% higher than conventional ICE cars. Moreover, EV credentials in terms of transport external costs reduction are very poor, particularly for congestion. If we look at research results comparing the external costs of different transport modes, high net benefits may be alternatively seen in public transport and rail based mobility (and also in short sea shipping for certain freight transport types) either in terms of energy efficiency and external costs reduction. An EU27 wide transport indicator based analysis is provided in chapter 4 to better highlight this "structural" additional driver of transport external costs, which has strictly little to do with vehicle level efficiency, rather it represents an efficiency in urban planning and infrastructural planning: a "system" efficiency in providing availability and access to highly energy efficient transport modes and services. In the final chapter recommendations for transport and energy European policies are provided, starting from a target setting based on external costs indicators (capturing also and not exclusively the energy efficiency and savings potential offered by transport infrastructures and vehicles), followed by an urgently needed Long term Action plan for railways networks and intermodality development. As to EVs, it is recommended to regulate them under an extension of the current EU CO2/km average target approach, by setting a common (final) energy consumption efficiency standard for all car innovations. Public funds collected from external costs road charging may be better concentrated by EU and Member States on this infrastructural Action Plan rather than on urban electricity grids for EVs.

Abstract:

This paper presents the research on vehicle fleet energy efficiency impact upon overall vehicle effectiveness. Transport companies and companies with own vehicle fleets tend to enhance their resource effectiveness, and to increase their transport service quality with the objective of attaining a competitive position on the market. Since energy consumed for transport operations is an important transport process resource, a method for assessing transport process effectiveness has been developed with the objective of increasing vehicle fleet effectiveness and its energy efficiency, and the overall vehicle effectiveness human indicator has been defined accordingly. The developed method was then implemented in an actual vehicle fleet and variations of the overall vehicle effectiveness human indicator were researched, as well as specific energy consumptions for respective net transport volumes depending on the following indicators: vehicle payload capacity utilization rate and mileage utilization rate. It is shown that specific energy consumption influences overall vehicle effectiveness depending on both the payload capacity utilization rate and mileage utilization rate.

Abstract:

El transporte es vital para el desarrollo social y económico de las sociedades alrededor del mundo. Por lo tanto, se tiene que considerar que el transporte masivo ha incrementado a través del tiempo con el consumo discriminado de combustibles fósiles que han servido para suplir la demanda en el transporte. Existen impactos sociales y medio ambientales que tienen que ser evaluados junto con la demanda de energía en Ecuador. La misma que en 2012 equivalió a 46 millones de BEP, donde 73% fue consumida por vehículos de carga pesada y 32% por vehículos de carga liviana. Este patrón de consumo combinado con una flota de vehículos ineficiente y un subsidio discriminado resulto en un derroche excesivo de energía. La investigación se enfoca en el análisis de la situación del transporte en Ecuador, para identificar el desperdicio de energía, el medio ambiente, y las oportunidades de eficiencia energética en este sector.

Abstract:

Transport costs are strongly influenced by fuel prices and fuel consumption in transport, i.e., energy efficiency. The aim of the article is to present the problem of energy efficiency in freight transport with the use of Heavy Duty Vehicles (HDV). The authors presented the factors of energy efficiency in road transport, energy efficiency of the road vehicles, the share of fuel costs in the total costs of transport companies and the relationship between the increase in fuel prices and the increase in transport rates. Research methods include, apart from literature analysis, interviews conducted in Polish transport companies in 2022 and the analysis of data collected by the authors on the transport services market over the last 20 years. The increase in rates over the last 20 years, until 2021, largely coincided with the increase in fuel prices, while in 2022, for the first time in this period, the increase in fuel prices was greater than the increase in rates. However, the prices for transport services increased with the increase in energy consumption costs, not with changes in fuel prices. The cost of energy consumption depends on the efficiency of its use, which is constantly increasing, although to a small extent. Research shows that the efficiency of fuel consumption in high-tonnage transport changes at a rate of 0.8–1% per year while the proportion of fuel costs in Polish transport companies transporting goods by road in the last 20 years oscillates between 29% and 46%. There was also an increase in the freight rates on this market, in most cases by over 30%. Despite this, however, the profitability of some companies deteriorated. A large increase in transport rates, compensating for the increase in fuel prices, applies mainly to transport companies whose strategy is to compete with the quality of services, and when high-value loads are transported, while a small increase in transport rates, which does not compensate for the increase in fuel prices, applies mainly to companies whose strategy is to compete on the price of transport services and when low-value cargo is being transported. The results of research on the market in Poland conducted by the authors of the article agrees with the results and opinions of other authors and researchers from other countries. The authors also agree with the view that the possibilities of increasing the efficiency of energy consumption in road transport by the carriers themselves are limited. The road transport market, especially in Poland, is highly competitive, which results in high efficiency of transport processes. However, this efficiency is largely affected by factors beyond the control of these companies (technological factors, infrastructure and energy sources). It seems that the involvement of the state is necessary. The research carried out by the authors of the article also confirmed the existing relationships between the weight of the transported cargo and energy consumption identified by other authors.

Abstract:

Aim: The aim is to recognize the main determinants of the energy efficiency improvement in transport in Poland in the years 2000-2014 using structural and index decomposition analysis, and to identify areas where there is still potential for further reduction of energy consumption.Design / Research methods: Techniques used to analyse changes in energy use are: structural decomposition analysis and index decomposition analysis. Each of these two methods is characterized by distinctive, unique techniques and approaches, as they have developed quite independently. Index decomposition analysis measures the impact of energy efficiency gains on the level of energy consumption, at the most detailed sector disaggregation level allowed by the available data. Whereas structural decomposition analysis allows to analyse the impact of the external factors, such as technological, demand, and demographic effects, on the fluctuations of the total energy consumption. The similarities and differences between the two approaches are summarized and illustrated with a numerical example of Polish transport.Conclusions / findings: The article recognizes the main determinants of the energy efficiency improvement in transport sector in Poland in the years 2000-2014. In case of Poland ODEX shows an overall progress of energy efficiency in transport by 24.3%. Results obtained with decomposition analysis indicate large divergences in energy efficiency improvements between modes of transport and vehicle types and identify areas where there is still potential for further reduction of energy consumption. Results from decomposing structure of energy use, show activity effect to be main reason for energy use growth. The distribution of each mode in total traffic of passengers and goods changes toward less energy efficient modes. The only factor driving down the energy use is energy savings.Originality / value of the article: Using two methods of decomposition analysis and comparing obtained outcomes allows to get a broader view on energy use trends. Results presented in this article are a good starting point for further detailed analysis of changes in energy use of transport.

Abstract:

Modern cargo flow nowadays requires proper analysis in order to optimize the costs and environment impact. To properly assess the ports at eastern Adriatic region transport energy efficiency and emissions were analysed, including both sea and land transport. For the sea transport Otrant gate was chosen as an entry point in Adriatic Sea. The analysed ports are Trieste, Koper and Rijeka as well-established container terminals and ports of Zadar and Ploče as terminals which in future may provide significant service. For the land transport, using both truck and train, Budapest was chosen as a final destination due to its location further in land at similar distance from all selected ports. As a cargo unit one 10 tonne TEU unit was used. The purpose of this analysis was to determine required energy to transport that one unit and emissions which such transport produce, not a volume or speed of transport. All the calculations were made using EcoTransIT calculator. The results showed that north Adriatic ports have one of the best positions in terms of efficiency of land transport, however southern Croatian ports have to develop transport infrastructure, mainly railroad, to be considered as a notable stakeholder.

Abstract:

The world is becoming more dependent on energy resources, which translates into political dependency on energy-exported states. This will significantly impact the economy, transport, and the environment around the world. Railway transport is becoming an essential mode of transportation because it can operate on an electrified network and has zero carbon emissions. High-Speed Railways (HSR) is an energy-intensive transport system, and it is important economically and environmentally to reduce the amount of used energy. This study examined high-speed rail from an energy efficiency point of view and found factors that can significantly reduce the energy consumption of high-speed rail. This research aims to answer the question that motivated this research: what fundamental factors affect the energy consumption of the selected HSR systems? It estimated the dynamic changes in the total energy consumption for seven HSR systems from 2010-2017 and benchmarked the most energy efficient HSR systems. The non-radial Data Envelopment Analyses methodology has been used to fulfil this research. To conduct complex statistical analyses, IBM SPSS has been applied. The main findings have shown that the decrease in vehicle mass, improved design of high-speed rolling stock and increased occupancy of trains will support the reduction of energy consumption by high-speed railways. The changes in energy consumption strongly correlate with the type of high-speed rolling stock and operational strategies. The expected outcomes of this research will contribute to developing and advancing more sustainable HSR systems. This research will support train operators in making decisions when acquiring new trains and assess the benefits of acceleration in modernising the current rolling stock.

Research in this paper comprised experimental determination of energy efficiency of different bus subsystems (diesel bus, trolleybus and fully electric bus) on chosen public transport route in Belgrade. Experimental measuring of energy efficiency of each bus type has been done based on the analysis of parameters of vehicle driving cycles between stops. Results of this analysis were basis for development of theoretical simulation model of energy efficiency. The model was latter compared with the results of simulation done by "Solaris bus & Coach" company for the chosen electric bus route. Based on demonstrated simulation, characteristics of electric bus batteries were defined, the method and dynamic of their recharge was suggested, as well as choice for other aggregates for drive system and technical characteristics for the electric buses were suggested.

Abstract:

The problems of storage and supplying the energy, together with reducing energy intensity for transport, are now crucial for developing sustainable and reliable transport systems. The energy network must be gradually adapted to new loads and power consumption patterns, especially in railways. The article aims to develop the simulation model to investigate the energy storage systems in its use in the electric transport infrastructure. The authors review selected technical solutions for electric energy storage in transport. The theoretical aspects of energy exchange in the energy storage systems were presented as a base for a continuous simulation model of electric transport power supply. In the non-periodic random voltage input applied to the storage unit, it is pro-posed to use the calculation method based on the Duamel integral to analyze its charge-discharge processes. The resistance functions were applied to analyze the traction power supply mode with variable in time and space by active loads. The simulation showed that the direct connection of the unit to the traction network significantly reduces the traction energy consumption.

Abstract:

The article reflects the issues of forecasting the target indicators of energy efficiency on the example of JSC «Russian Railways». The approaches selected for assessing the quantitative values of the key performance indicators of the Russian Railways holding in the development of the Energy Strategy for the period up to 2020 and for the future up to 2030 are considered. The accepted methods are conventionally classified into four groups, including: a heuristic method based on the analysis of time trends, an indirect method based on known values of indicators and using mathematical models. The method of forecasting the specific consumption of electricity and diesel fuel for train traction and the energy intensity of the production activity of JSC «Russian Railways» is considered in detail. Regression models have been developed that characterize the dependence of the specific fuel and energy consumption on such indicators as the volume of transportation work, the average mass of the train, and the share of freight work in the total work. In order to assess the accuracy of the obtained forecast values of the indicators included in the energy strategy of JSC «Russian Railways», they were verified by the results of 2017-2019. The results obtained allow us to speak about the sufficient effectiveness of the approaches considered in the article to predict the KPI of JSC «Russian Railways». The error in forecasting the main indicator of energy efficiency of JSC «Russian Railways» - the energy intensity of production activities - was 0,06 %.

Abstract:

Abstract Most of the time, modern transport vehicles operate in unsteady modes. Undoubtedly, the reasons for the decrease in the efficiency of machines are fluctuations in speed and load, their deviations from the optimal values cause an increase in energy losses. Another reason for the increase in energy losses is the process of forced braking when it is necessary to stop the car. A class of vehicles with hybrid propulsion systems that can recover braking energy are currently being developed. Significant advantages among them are transport vehicles with a flywheel energy storage, which have a long service life. This article discusses the energy model of transport vehicles with the possibility of braking energy recuperation.

Abstract:

The article proposes a method of monitoring the transport energy efficiency of cars for long-distance freight transport, which is developed on the example of the analysis of the characteristics of low-capacity vehicles. It is relevant in terms of providing conceptually-oriented renewal of rolling stock for long-distance transport in a market economy. The object of study is the transport and technological process with the use of light-duty vehicles in the conditions of long-distance transportation. The purpose of the work is to form a method of monitoring and analysis of transport energy efficiency of cars for the renewal of rolling stock in suburban and long-distance freight. To achieve this goal, the theory of energy efficiency of a generalized type of car is used. Regularities of quantitative influence of various factors (road resistance index and coefficient of static capacity utilization capacity of rolling stock) on the values of light-duty transport energy efficiency indicators on the calculated main routes are determined. The results of the article can be used in transport companies transporting in Ukraine.

Abstract:

The article considers the problems of energy efficiency management of the rolling stock of the transport sector. The operation and operation of vehicles are analyzed and it is determined that road transport is the main consumer of energy resources in the transport sector, which is about 90%. Road transport requires 6.5 times more fuel than rail, and 5 times more fuel than sea or river. It has been studied that the transport sector has a negative impact on environmental friendliness due to high emissions. To successfully solve this problem, it is necessary to use bioenergy, which will increase the energy efficiency and environmental friendliness of the transport sector and is a strategy for the development of the transport sector of the country and the European Union. An analytical review of legislative acts, namely EU directives and national transport strategy for the period up to 2030, which regulate the promotion of energy efficiency in transport. The main groups of tools and the use of information technology are considered, which allow to achieve the set goals in the development of energy efficiency in transport. The impact of alternative fuels resulting from the processing of biological waste or biological raw materials for the country's transport sector, in particular road transport, which will significantly reduce CO2 emissions, has been studied. Biofuels are able to provide clean energy for all modes of transport and are currently the most important type of alternative fuel. Its influence on improving the energy efficiency and environmental friendliness of the transport sector has been studied.

Abstract:

China’s huge investment in the “belt and road initiative” (BRI) may have helped improve the economic level of participating countries, but it may also be accompanied by a substantial increase in greenhouse gas (GHG) emissions. The BRI corridors aim to bring regional stability and prosperity. In such efforts, energy efficiency due to increased transport has been overlooked in the recent literature. This paper employed a data envelopment analysis of the slack-based measurement (SBM) for bad output to assess the transport energy efficiency of 19 countries under the BRI economic corridors. By using the most cited transport-related input variables, such as vehicles, labor, motor oil, jet fuel, and natural gas, this study first analyzes the transport energy efficiency by first assuming the output variables individually and then takes two years as a pre- and post-BRI case by considering the aggregated output model. The results show an increase in economic activity but a decline in transport energy efficiency in terms of consumption and emissions.
