The goal of the study is to propose the basis for the concept of expanding the fuel balance in Russia through the development of a closed-loop resource cycle. We propose to use the criterion of energy potential of waste to generate new data on the resource base of the fuel and energy complex at the regional level. In order to form a reliable source for replenishment of the resource potential of the fuel and energy complex through waste recovery, the basic principles of data collection are proposed and the methodology for determining the energy potential at the city level is demonstrated using municipal solid waste (MSW) in 11 Russian cities as an example. The results of the evaluation have shown that due to energy recycling, MSW can cover from 2.11% to 6.01% of the heat demand of the territory under consideration. In the study, we propose to supplement the maximum involvement of waste in the fuel and energy balance (FEB) in Russia with the criterion of optimization of the energy balance at all levels and to distinguish a separate column “energy potential of waste” in the balance structure. This approach fundamentally changes the structure of the balance and gives the grounds for revision of plans for production and transportation of traditional energy resources.

In this article analyzes the development of trends of bioenergy crops market development in Ukraine and its current state are analysed. The possibility and feasibility of synergy of mutual development of bioenergy crops market and bio-oil market in Ukraine were noted. The necessity of state support and stimulation of bioenergy crops and different types of biofuels production in Ukraine was stated. A positive trend of growth of planted areas and production of rapeseed in Ukraine was revealed. During the study period (2013-2019) the production of rapeseed was increased by 1.4 times. The greatest energy potential for the production of bioethanol is in the sugar beet subcomplex of the agricultural sector. Over the past few years, the production of sugar beet was at its highest in 2014 (15.7 million tonnes), while the following years saw a decrease in cultivated areas of sugar beet and, consequently, a drop in its gross output - to 8.3 million tonnes in 2020. Significant resource potential for the production of bioethanol also have cereal crops (wheat, rye, barley, maize), the area under which during the last ten years remains relatively stable (14.4-15.3 million ha). Among grain crops the most effective raw material for the production of bioethanol is maize. A positive tendency of biennial growth of planted area under this crop is revealed. The space differentiation of resource base of bioenergy in Ukraine is prominent. The cluster analysis revealed three groups of areas based on the similarity of the energy resources for bioenergy purposes. Two clusters including Khmelnytskyi, Ternopil, Zhytomyr and Chernihiv, Vinnytsia, Cherkasy, Sumy, Kirovograd, Poltava and Kyiv regions should be considered as the most promising areas for concentration of capacities in biofuel production. It is noted that the trajectory of development bioenergetic sector of the country is always conditioned by compromise between compliance with optimal levels of its energy and food security.

Good Agreement

An analytical, experimental investigation of the thermal performance of a tubeless V-trough concentrator has been carried out. Considering the energy balance on the receiver plate, a mathematical expression is developed from which the receiver plate mean temperature can be evaluated for each time interval. The good agreement between the experimental results and the analytical predictions indicate that the construction of a tubeless absorber panel might be valuable and the analytical approach might have the potential for further extensions. It has been found, according to the expermental investigation, that the fluid outlet temperatures vary between 69°C and 91 °C from 10:30 a.m. on up to the termination of operation in the late afternoon. This qualifies the V-trough to be a reliable source for providing temperatures in this range that can be utilized in heating and cooling applications.

Renewable Energy Production

- The Italian energy balance for year 2005 is discussed with particular attention on renewable energy production. The potentials of renewable sources are evaluated in terms of energy density that can be obtained from occupied plant area. About 20000 km2 of sunny barren lands are present in South of Italy, particularly suitable for photovoltaic plants and that corresponds to a potential production of 144 Mtep of primary energy. Therefore, in theory, the photovoltaic energy potential is comparable with energy balance. The grid connection limit due to intermittent power generation of photovoltaic and wind energy systems is considered in relation with the stability of grid power level. Assuming a 25% maximum grid penetration of intermittent power with respect to capacity of active thermoelectric generators, the renewable energy contribution amounts to about 2% of annual energy balance. In front of expectations for a larger contribution, the practical result is the renewable energy production of present systems is marginal, unsuitable for counteracting the global climate crisis. The conclusion is that, for exploiting the large renewable energy potential, is necessary to implement the plants with an energy storage system able to overcome the source intermittency. Without this improvement, the expectations on renewable energy sources could be disappointed.Key words: intermittent renewable sources, energy production limit, grid connection

The Impact

The main sources of thermal energy for the heat supply of cities and settlements are fuel-based thermal power plants and boilers. The article provides an analysis of the energy balance of a power plant in connection with the need to minimize the cost of fuel and electricity for heat supply. New analytical expressions comprehensively characterizing the efficiency of a power plant are developed. The analytical assessment of the impact of energy costs for the boiler needs on the energy balance of thermal power plant is made; methods for constructing schemes of the energy balance of thermal power plant and assessment of fuel efficiency in the boiler are designed. Attention is paid to errors arising from the use of the calculated values of air suction in the gas path of the boiler, and not the actual ones. Therefore, it is proposed to change the method of measuring heat loss with flue gases in order to eliminate or reduce the effect of air suction on the measurement results, taking into account the part of the flue gas heat received by the air in the air heater and returned to the boiler through the burner. The methods increasing accuracy of calculations of energy efficiency of the technological processes which are key in the centralized heat supply of the cities and settlements are developed.

This article investigates the potential of selected urban typologies in Vienna to reach the state of Positive Energy Districts (PED) by achieving a positive annual energy balance. It follows the EU initiative for implementing at least 100 PED in Europe by 2025. Four urban typologies have been assessed using the bottom-up energy modelling tool MAPED that enables a simplified energy demand-supply analysis at the district scale. Considering relevant urban typologies in different construction periods, the analysis focused on converting the allocated building stocks into PED by employing comprehensive thermal refurbishment and energy efficiency measures, electrification of end-uses and fuel switching, exploitation of local renewable energy potential, and flexible interaction with the regional energy system. The results reveal that a detached housing district can achieve a positive annual energy balance (for heat and power) of 110% due to the fact that there are sufficient surfaces (roofs, facades, open land) available for the production of local renewable energy, whereas the remaining typologies fail to achieve the criteria with an annual balance ranking between 61% and 97%, showing additional margins for improvement to meet the PED conditions. The presented concept offers a practical approach to investigate the PED suitability of urban typologies. It will help the Austrian Ministry for Climate Action and Environment to identify appropriate strategies for the refurbishment of existing urban areas towards the PED standard.
