The article presents the results of research related to the SDG7 sustainable development implementation analysis. The goal is to provide affordable and clean energy. Its implementation will allow for development that will simultaneously provide the possibility of economic growth and the achievement of an optimal level of citizens’ health and life. The research was conducted for the countries of the European Union EU-27. During the analysis, the indicators proposed by Eurostat were used. The research aimed to examine the progress in EU member states’ energy markets integration. In order to carry out the indispensable research, it was necessary to use a spatial information system. Cluster analysis, as well as TSA analysis, were applied. The conducted research made it possible to verify the posed hypotheses and showed that the energy transformation process of the EU-27 countries is so complicated and heterogeneous that it has given rise to new independent and unique clusters. The authors also verified the adopted set of SDG7 achievement indicators using multiple regression. Additional indicators were also proposed that could complement the set and clarify its analyses.

“…An attempt to find a compromise between the specifics of the Polish power sector and the requirements of the EU climate policy may be made by developing clean coal technologies (CCTs) [17,18]. In this case, the term refers to low-and zero-emission coal-fired units which, by guaranteeing a high energy efficiency, will reduce the emission of CO 2 , nitrogen oxides, and sulfur compounds to the atmosphere [55].…”

“…To support decision-makers, in addition to the basic rules of decision analysis based on the economic evaluation of projects, it is possible to apply an approach from the MCDM (multiple-criteria decision-making) area [15]. In terms of technologies that provide CO 2 emission reductions, clean coal technologies could enter the spotlight, with the potential of coupling conventional power generation methods with distributed renewable energy sources [16][17][18]. For this study, a preliminary choice of decision variants was made, and the overriding selection criterion was to reduce the harmful environmental impact of conventional coal-fired power generation, as well as to achieve the required availability and flexibility of the generating sources from the point of view of system operation, comparable to the use of conventional gas-fired sources.…”

“…Despite many studies in this area, the issue of selection itself and the support to the decision concerning the selection of conventional sources and widely understood clean coal technologies is not fully resolved. Authors who address the topic of coal-based generation sources consider country-specific cases, among which publications referring to the energy sector in China dominate [17,[35][36][37][38]. The choice of the Polish energy sector as the case study is justified, as there are few publications on the selection of coal-fired generation sources dedicated to the domestic sector [39,40]; moreover, no publications use the SMART method for this purpose.…”

The process of technology management contains various stages, such as the identification, selection, acquisition, implementation, and maintenance of technologies. In the case of power generation companies, a key aspect of the selection stage is the choice of generation technologies for newly commissioned units. The investment decision depends on many factors, primarily economic, environmental, social, technological, and legal, and represents a complex multi-criteria problem. Currently, the decision is further complicated by the often unpredictable tightening of environmental standards, forcing the closure of conventional sources, on which many countries have so far based their energy security. The paper analyzes the problem of choosing one of the so-called clean coal technologies to be implemented in conditions of transformation of the power sector. In this paper, five selected clean coal technologies are characterized, and the SMART method is adopted to technology selection. The following technologies were considered: supercritical coal-fired power plant (with and without CCS), IGCC power plant (with and without CCS), and IGCC power plant with CCS and integrated hydrogen production. Nine practical criteria (in three main groups: environmental, technological, economic) for comparing technologies are defined, computational experiments performed, and conclusions from the research presented. The work was based on the literature study of multi-criteria decision support and an analysis of power sector needs based on the example of the Polish power sector. The conducted research, apart from the technology recommendation, led to the conclusion that the chosen method may be applied to decision-making in the field of power generation technology management. The study also indicated the potential direction of the development of a power generation structure in a situation where a component of ensuring energy security is the use of available coal fuels.

“…Thus, all the technological operations of underground coal gasification are performed from the earth's surface without miners' underground operations. The technology belongs to so-called clean coal technologies, it is environmentally safe, and it can become a great alternative to extraction [48][49][50][51][52].…”

Experimental Studies of the Effect of Design and Technological Solutions on the Intensification of an Underground Coal Gasification Process

et al. 2021

This paper represents the results of experimental studies of physical modeling of the underground coal gasification process in terms of implementation of design and technological solutions aimed at intensification of a gasification process of thin coal seams. A series of experimental studies were performed in terms of a stand unit with the provided criteria of similarity to field conditions as well as kinetics of thermochemical processes occurring within a gas generator. Hard coal (high volatile bituminous coal) was selected as the raw material to be gasified, as that coal grade prevails in Ukrainian energy balance since it is represented by rather great reserves. Five blow types were tested during the research (air, air–steam, oxygen–steam, oxygen–enriched, and carbon dioxide and oxygen). As a result, the effect of tightness of a gas generator on the quantitative and qualitative parameters of coal gasification while varying the blow by reagents and changing the pressure in a reaction channel has been identified. Special attention was paid to the design solutions involving blow supply immediately into the combustion face of a gas generator. The experimental results demonstrate maximum efficiency of the applied gas generator design involving flexible pipelines and activator in the reaction channel and a blow direction onto the reaction channel face combined with blow stream reversing which will make it possible to improve caloricity of the generator gas up to 18% (i.e., from 8.4 to 12.8 MJ/m3 depending upon a blow type). Consideration of the obtained results of physical modelling can be used with sufficient accuracy to establish modern enterprises based on the underground coal seam gasification; this will help develop more efficiently the substandard coal reserves to generate heat energy as well as power-producing and chemical raw material. The research conclusions can provide technical reference for developing a new generation of underground coal gasification technology.
