Low-Grade Coals: A Review of Some Prospective Upgrading Technologies<sup>†</sup>

2009-06-15

Hassan Katalambula , Rajender Gupta

Low-grade coals are usually those that are low in specific energy because of high moisture content and/or ash content or produce high emissions of concern. These are commonly lignites or … Low-grade coals are usually those that are low in specific energy because of high moisture content and/or ash content or produce high emissions of concern. These are commonly lignites or sub-bituminous coals. There is a growing need of using these low-grade coals because of higher quest for power generation. In general, the direct use of the low-grade coals results in higher costs of reducing emissions or in lower efficiency and, consequently, higher greenhouse gas emissions. In the present carbon-constrained environment, there is a need of upgrading these coals in terms of moisture, ash, and/or other trace elements. There are a number of upgrading technologies. The current paper reviews these technologies mainly categorized as drying for reducing moisture and cleaning the coal for reducing mineral content of coal and related harmful constituents, such as sulfur and mercury. The earliest upgrading of high-moisture lignite involved drying and manufacturing of briquettes. Drying technologies consist of both evaporative and non-evaporative (dewatering) types. The conventional coal cleaning used density separation in water medium. However, with water being a very important resource, conservation of water is pushing toward the development of dry cleaning of coal. There are also highly advanced coal-cleaning technologies that produce ultra-clean coals and produce coals with less than 0.1% of ash. The paper discusses some of the promising upgrading technologies aimed at improving these coals in terms of their moisture, ash, and other pollutant components. It also attempts to present the current status of the technologies in terms of development toward commercialization and highlights on problems encountered. One thing that is obvious is the fact that, despite the presence of all these techniques, still the upgrading goal has not been realized adequately. It can therefore be concluded that, because reserves for low-grade coals are quite plentiful, it is important to intensify efforts that will make these coals usable in an acceptable manner in terms of energy efficiency and environmental protection.

Distributed Generation in Liberalised Electricity Markets

2002-06-26

Comparison of variational principles.Following Reissner's presentation and proof in isothermal elasticity, a comparison can be made between the values of I for functions tu , , etc. which are not solutions of SI = 0 and for functions r,-,-, etc. which are determined from 81 = 0.If both W and D are positive definite quadratic forms, the conclusion is reached that in the extended variational theorem for displacements (solid and entropy) one is concerned with a minimum problem, while in the extended variational theorem for stresses one is concerned with a maximum problem.In contrast to this, Reissner's general variational theorem, as extended to thermoelasticity and heat conduction, is only a stationary-value problem.1960 6.

This results from the economic issues and the measures taken to ensure the energy security. The aim of this research was to determine the significance of renewable energy sources (RES) in the energy mix of Poland, and to elicit the opinions and the level of knowledge of the society on the use and development of non-conventional energy. The article also presents advantages and disadvantages of types of RES, the obstacles which hinder the progress of green energy in Poland, and the proposed measures to expand the share of the RES in the overall energy mix. The research relied on the statistical data gathered by Statistics Poland. The opinions of respondents were elicited through a diagnostic survey based on a questionnaire. The research has demonstrated that the respondents support the development of RES in Poland. However, they also maintain that the purchase and installation of devices for the production of non-conventional energy are too expensive. The respondents believe that in order to increase the number of green power plants, subsidies to encourage RES investment and tax reliefs related to this investment should be bigger.

The … The EU has a comprehensive legislation to facilitate the energy transition towards a low carbon energy system and achieve the EU's Paris Agreement commitments for reducing greenhouse gas emissions. The European Green Deal is an integral part of the EU strategy for a sustainable and climate neutral economy by 2050. The decarbonisation of the power generation is essential to achieve the goal of decarbonising the energy and transport sectors. This paper presents a study conducted to quantify the carbon emissions associated to the production of electricity produced and used in European countries, based on a comprehensive methodology developed for this purpose. A spreadsheet model has been developed that considers the various sources for electricity generation, the type of plants, conversion efficiencies, upstream emissions and emissions from power plant construction, as well as the electricity trade. The results show the greenhouse gas emissions from the production and use of electricity in all European countries, revealing significant variations between countries. The carbon intensity of electricity shows a clear reduction trend since 1990, for most of the European countries. In the European Union, carbon intensity of electricity used at low voltage degreased from 641 gCO2eq/kWh in 1990 to 334 gCO2eq/kWh in 2019, and this trend is expected to continue in the coming years.

Larger units are generally … The emphasis of this article is on distributed generators that are interconnected to with utility distribution systems. These will generally be units smaller than 10 MW. Larger units are generally connected directly to transmission facilities and will most likely be commercial power producers. The units installed on distribution systems will typically be no larger than 1 or 2 MW. These would be installed mostly by the utility itself or by end users. This method of generation is commonly referred to as "distributed generation" (DG).

W 2020 r. po raz pierwszy w historii udział przypadający na LNG przekroczył ponad 50% globalnego handlu gazem. Podjęta w artykule problematyka analizy znaczenia dostaw gazu skroplonego do bilansowania zapotrzebowania na gaz ziemny ma istotne znaczenie dla bezpieczeństwa energetycznego, szczególnie obecnie w kontekście wojny w Ukrainie. Analiza badawcza przedstawiona w artykule w ujęciu podmiotowym odnosi się do państwa, zaś w kategorii przedmiotowej do gazu ziemnego, a w szczególności LNG. Wykorzystana została metoda analizy czynnikowej, a także analiza porównawcza. Sformułowane zostały następujące wnioski. Po pierwsze, trwająca wojna w Ukrainie stała się głównym czynnikiem wpływającym na wzrost zapotrzebowania gazu skroplonego oraz wpłynęła na zmianę architektury kontraktów gazowych. Gaz ziemny zyskuje na znaczeniu w Polsce. Po drugie, dynamicznie zmieniająca się sytuacja na światowych rynkach energetycznych doprowadziła do zmiany na pozycji lidera eksportu LNG w skali globalnej, którym stały się USA. Po trzecie, proces dywersyfikacji dostaw gazu ziemnego do Polski jest możliwy dzięki rozbudowanej infrastrukturze energetycznej. Obserwuje się, że po 2022 roku znaczenie terminala L NG w Świnoujściu wzrosło i stanowi on dzisiaj jeden z najbardziej strategicznych obiektów infrastruktury energetycznej w państwie.

Próbki biomasy surowej spalano w temperaturze 450–500 ± 15°C. Gatunki drzew pochodzą z Polski (województwo małopolskie) oraz z Parku Narodowego „Bory Tucholskie” (województwo pomorskie). Celem niniejszego badania było określenie zawartości metali toksycznych (As, Cd, Cr, Cu, Hg, Ni, Pb, Tl) w biomasie surowej i jej popiołach, wymywanych jonów z eluatów wodnych popiołów i analiza procesu termicznej degradacji drewna. W&nbsp;badaniach wykorzystano metodę spektroskopii emisyjnej ze wzbudzeniem w plazmie indukcyjnie sprzężonej (ICP-OES ) i chromatografię jonową (IC), wykonano analizy termograwimetryczne (TG /DSC) oraz dyfrakcję rentgenowską metodą proszkową (XRD). Zawartość części lotnych w biomasie drzewnej waha się między 67,2–82,5%, zawartość popiołu 2,9–19,1%, a wartość kaloryczna wynosi 14,8–17,1 MJ/kg. Zawartość wilgoci w biomasie drzewnej waha się między 14,6–18,7% (brzoza) i 17–19,2% (olcha). Skład mineralny badanych próbek jest mało zróżnicowany. Zawartość metali toksycznych jest na ogół niska w biomasie surowej, z wyjątkiem miedzi, cynku i niklu, oraz wyższa w popiołach, zróżnicowana w zależności od pochodzenia biomasy. Krzywe TG /DSC pozwoliły zidentyfikować główne etapy degradacji biomasy drzewnej, które odpowiadają zawartości wilgoci w zakresie 2,73–5,83% (wag.), popiołu 0,58–3,68% (wag.), materiałów lotnych 59,63–76,46% (wag.) oraz węgla stałego 20,23–32,3% (wag.). Wyższe stężenia jonów siarczanowych i potasowych oznaczono w eluatach wodnych popiołów z Parku Narodowego „Bory Tucholskie”. Wyniki badań niejednoznacznie wskazują, że olcha i brzoza mogą być wykorzystane w spalaniu niskotemperaturowym; jednak wskazane jest prowadzenie kompleksowych badań w tym zakresie.

Opracowywane są plany dekarbonizacyjne związane z odchodzeniem od węgla, a w strategiach średnio- i długoterminowych podkreślana jest rola gazu ziemnego. Tendencja ta jest również obserwowana na rynku mocy – elektrownie i elektrociepłownie opalane gazem ziemnym są jednymi z głównych beneficjentów tego mechanizmu wsparcia, zwłaszcza pod warunkiem uwzględnienia czasu trwania umowy mocowej. Przedstawione w artykule badania poświęcone są zbadaniu wpływu wyników głównych aukcji mocy (na lata dostaw 2021–2029) na przyszłe zużycie gazu ziemnego w polskim systemie elektroenergetycznym. W&nbsp;tym celu przeanalizowano wyniki tego mechanizmu wsparcia oraz zidentyfikowano jednostki rynku mocy pod kątem paliwa wykorzystywanego do produkcji energii elektrycznej. Uzyskane wyniki wskazują, że dodatkowe zapotrzebowanie na gaz ziemny (pochodzące głównie z elektrowni gazowo-parowych, ale także z jednostek kogeneracyjnych, w tym turbin gazowych pracujących w cyklu prostym i silników gazowych, o łącznej mocy brutto około 5,0 GWe), może wynieść od 2,8 do 8,5 mld m3 w perspektywie 2030 r., w zależności od przyjętego współczynnika wykorzystania mocy zainstalowanej (30–90%), przy czym zapotrzebowanie na poziomie około 6,6 mld m3 uzyskano dla współczynnika wykorzystania mocy równego 70%. Budowa wielkoskalowych gazowych jednostek wytwórczych przy wsparciu z rynku mocy, istotnie wpływa (m.in. zmiana miksu paliwowego, potrzeba rozbudowy infrastruktury przesyłowej, uzależnienie od cen surowca z importu, ryzyko zakłóceń podażowych etc.) – w perspektywie długoterminowej – nie tylko na sektor energetyczny, ale również paliwowy, oddziałując na bezpieczeństwo dostaw gazu ziemnego do Polski.

Current approaches often rely on overly general assumptions, leading to considerable errors in specific applications or, conversely, overly specific measurements that limit generalisability. We aim to present a comprehensive data-driven methodology for analysing energy consumption within a large urban agglomeration. The method leverages a unique and extensive set of real-world performance data, collected over two years from onboard recorders on all public bus lines in the Capital City of Warsaw. This large dataset enables a robust probabilistic analysis, ensuring high accuracy of the results. For this study, three representative bus lines were selected. The approach involves isolating inter-stop trips, for which instantaneous power waveforms and energy consumption are determined using classical mathematical models of vehicle drive systems. The extracted data for these sections is then characterised using probability distributions. This methodology provides accurate calculation results for specific operating conditions and allows for generalisation with additional factors like air conditioning or heating. The direct result of this paper is a detailed urban map of energy demand and peak power for public transport vehicles. Such a map is invaluable for planning new traffic routes, verifying existing ones regarding energy consumption, and providing a reliable input source for strategic charger deployment analysis along the route.

First-generation biofuels are … Currently, about 10% of the energy in the world is biofuel energy from plant biomass. Anaerobic fermentation is a sustainable technology in waste processing and energy production. First-generation biofuels are made from dedicated feedstocks and conversion technology bioenergy crops. Second-generation biofuels are bio-based products derived from non-food feedstocks, which are agricultural and forestry feedstocks. Third-generation biofuels are produced from aquatically cultivated feedstocks. To assess the output of biogas from biomass, it is necessary to perform calculations of anaerobic fermentation processes. The well-known Buswell model allows for the theoretical determination of the amount of biomethane from a substrate with organic substances. The method estimates the output of anaerobic fermentation products based on theoretical stoichiometric evaluation. Theoretical Biochemical Methane Potential considers all organic substances as biodegradable. The amount of biomethane (nCH₄) is a parameter that depends on the elementary composition of organic matter. To determine nCH₄, measurements and calculations based on elemental analysis are required. The empirical formula of organic matter can be determined using stoichiometric equations. Higher values are obtained for grains and lignin - from 698.6 to 705.4 dm³/kg, for wood and straw the biogas yield is from 476.5 to 514.2 dm³/kg. Solid wastewater sludge - 570 dm³/kg. Biogas from anaerobic fermentation not only represents a clean energy source but also contributes to reducing the volume of solid waste and greenhouse gas emissions. Anaerobic fermentation can also be integrated into various agricultural and industrial processes

This technology not only meets … An innovative trend in the energy sector such as virtual power plants (hereinafter referred to as VPPs) opens new horizons for modernization of the industry. This technology not only meets modern requirements for flexibility and sustainability of power systems, but also contributes to their more efficient integration. By consolidating distributed energy resources, VPPs contribute to grid reliability and economic efficiency. Despite the obvious advantages, VPPs integration into existing energy markets is fraught with serious obstacles. The key issue remains in the lack of an adequate regulatory framework that can consider the specific features of these innovative systems. This fact dictates an urgent need for developing innovative approaches to VPPs regulation. The study aims to identify and examine in detail the potential application of VPPs in modern energy sites. The methodological basis is a comprehensive STEEP analysis covering social, technological, environmental, economic, and political aspects of virtual power plants. This toolkit allows for a comprehensive assessment of both the challenges and potential benefits of implementing VPPs. The need to create a favorable environment for VPPs development through forming appropriate political and regulatory infrastructure has been established. Only a comprehensive approach, considering all aspects of STEEP analysis, can ensure full realization of virtual power plants potential in modern energy sector.

As concessions serve as … Poland is a country with significant lignite resources. Prospecting for and exploring lignite deposits, as well as lignite extraction, requires prior acquisition of an appropriate concession. As concessions serve as instruments for regulating economic activity—and thereby constitute a form of permissible restriction on such activity under the Polish Constitution—the legal provisions governing them must be enacted by statute. This article analyzes the role of state policies relating to lignite extraction and its use in electricity generation, and examines the concession procedure as a regulatory instrument, with a particular focus on one specific ground for refusing to grant a concession: inconsistency with the state’s raw material interest. The main research question addresses whether the incorporation of the state’s raw material interest as grounds for refusal complies with constitutional standards and whether policy documents—specifically the State Raw Materials Policy and the State Energy Policy—can effectively guide its interpretation. The analysis concludes that, while the constitutional framework permits such a ground for refusal, current policy documents require updates and greater specificity to ensure legal certainty and consistency in administrative practices.

The article examines the potential and possibilities of biogas production in the EU countries due to the available biological waste and agricultural raw materials. The state of technology and development of the biogas market, the dynamics of production and conversion of biogas into electricity are characterized. It is determined that an important reason for the need to increase the use of renewable energy sources is the uncontrolled growth of household and industrial waste, which leads to environmental pollution and requires high costs for disposal. It is studied that modern methods of waste management through the production of biogas and biomethane can not only alleviate the global energy crisis, but also effectively protect the ecology of the environment. It is emphasized that biogas will play a key role in achieving Europe's long-term goals for energy security and mitigating the effects of climate change, as part of a promising and balanced complex of renewable energy sources. It has been proven that the production and use of biogas has a number of justified and confirmed by world practice advantages, since the availability of a wide range of necessary raw materials for the production of biogas and biomethane allows the construction of biogas plants in areas of concentration of agricultural production and technologically related industries. Special attention is paid to the role played by biogas and biomethane in the fight against climate change and the development of sustainable technologies, since sustainable development is the basis of the well-being of EU countries, it is respect for the environment in which the population of European countries lives and their future generations will live. This ideology underlies the development of the biogas industry in Europe. Based on statistical data of past periods and regression analysis, a calculation of the forecast volumes of energy production from biogas and biomethane in EU countries was made using a trend model and Excel spreadsheet editor. Considering the development perspective, it is determined that the transition to sustainable energy remains the most important for the EU economy, where the biogas sector can already provide a competitive and sustainable alternative to imported fossil gas thanks to domestic production.

It assesses the feasibility of Poland’s commitments to the European Union’s decarbonisation targets, particularly with regard to transitioning from fossil fuels to renewable energy sources and nuclear power. The study highlights the challenges related to the speed of the energy transition, the security of electricity supply, and the competitiveness of the national economy. The study also assesses the energy mix scenarios proposed in the NECP, taking into account historical energy consumption data, economic and demographic projections, and expert analyses of energy security. It also critically examines the risks of delayed investment in nuclear and offshore wind, the potential shortfall in renewable energy infrastructure, and the need for transitional solutions, including coal and gas generation. An alternative scenario is proposed to mitigate potential energy supply shortfalls between 2035 and 2040, highlighting the role of energy storage, strategic reserves, and the maintenance of certain fossil fuel capacities. Poland’s energy policy should prioritize flexibility and synchronization with EU objectives, while ensuring economic stability and technological feasibility. The analysis underlines that the sustainable development of the national energy system requires not only alignment with European climate goals, but also a long-term balance between environmental responsibility, energy affordability, and security. Strengthening the sustainability dimension in energy policy decisions—by integrating resilience, renewability, and social acceptance—is essential to ensure a just and enduring energy transition.

The conducted study concerns the analysis of the profitability of investment in a 1.65 MW wind turbine with a hub height of 70 m in various zones in Poland. The analysis was performed using the clustering method (cluster analysis and the Czekanowski diagram). Computer simulation was also used using the Hybrid Optimization of Multiple Energy Resources (HOMER), ver. x64 3.18.4 software. As a result, three zones were distinguished that ensure differentiation in the rates of return on investment in wind energy. The authors positively verified the hypothesis about the spatial differentiation of profitability in relation to the examined factors. The justification for investments in wind farms was demonstrated and factors determining their profitability were indicated. It was emphasized that, in the case of wind farms, energy production is relatively predictable, which shapes the benefits for investors, and facilitates financial planning and long-term return on investment.

Mariangela Guidolin , Stefano Rizzelli

Natural gas consumption in Europe has undergone substantial changes in recent years, driven by geopolitical tensions, economic dynamics, and the continent’s ongoing transition towards cleaner energy sources. Furthermore, as noted … Natural gas consumption in Europe has undergone substantial changes in recent years, driven by geopolitical tensions, economic dynamics, and the continent’s ongoing transition towards cleaner energy sources. Furthermore, as noted in the International Energy Agency’s Gas Market Report 2025, natural gas demand is becoming increasingly sensitive to fluctuations in weather patterns, including cold snaps and heatwaves. These factors make the task of forecasting future annual consumption particularly challenging from a statistical perspective and underscore the importance of accurately quantifying the uncertainty surrounding predictions. In this paper, we propose a simple yet flexible approach to issuing dynamic probabilistic forecasts based on an additive time series model. To capture long-term trends, the model incorporates a deterministic component based on the Guseo–Guidolin innovation diffusion framework. In addition, a stochastic innovation term governed by an ARIMAX process is used to describe year-over-year fluctuations, helping to account for the potential presence of variance nonstationarity over time. The proposed methodology is applied to forecast future annual consumption in six key European countries: Austria, France, Germany, Italy, the Netherlands, and the United Kingdom.

However, the integration of … Significant shortfalls in meeting the climate mitigation targets and volatile energy markets make evident the need for an urgent transition from fossil fuels to sustainable alternatives. However, the integration of zero-carbon fuels like green hydrogen and ammonia is an immense project and will take time and the construction of new infrastructure. It is during this transitional period that lower-carbon natural gas alternatives are essential. In this study, the industrial sectors of Lithuania are analysed based on their energy consumption. The industrial sectors that are the most energy-intensive are food, chemical, and wood-product manufacturing. Synthetic natural gas (SNG) has become a viable substitute, and biomethane has also become viable given a feedstock price of 21 EUR/MWh in the twelfth year of operation and 24 EUR/MWh in the eighth year, assuming an electricity price of 140 EUR/MWh and a natural gas price of 50 EUR/MWh. Nevertheless, the scale of investment in hydrogen production is comparable to the scale of investment in the production of other chemical elements; however, hydrogen production is constrained by its high electricity demand—about 3.8 to 4.4 kWh/Nm3—which makes it economically viable only at negative electricity prices. This analysis shows the techno-economic viability of biomethane and the SNG as transition pathways towards a low-carbon energy future.

At the same time, the literature promotes the implementation of a new way of farming that takes into account environmental, social, and economic concerns. We have brought together new methods and ways of farming in these areas into one broad concept, called the conclusion of sustainable development. Within this concept, particular emphasis has been placed on sustainable energy development, the intensive development of technologies based on renewable energy sources, and the advancement of end-user awareness of modern technologies. The aim of this paper was to identify the factors that determine the ecological attitude of users of single-family houses in Poland when making strategic energy decisions related to the choice of heating devices in a household. To solve this research problem, the authors conducted a nationwide survey on a representative sample of single-family house users. In turn, the results were analyzed using log-linear analysis. The results showed that the determinants of the ecological nature of such energy decisions are primarily the age of the house users and their level of education. It was found that younger people are significantly more likely to think about ecology when making decisions related to how a building is heated than older people. In addition, people with a higher level of education are more likely to think about ecology when making such decisions than those with a lower level of education. Findings showed that the gender of the occupant of a single-family house, as well as the size of the town in which the building is located, have no significant impact on the ecological nature of decisions related to the choice of the method of obtaining energy for home heating. It was also shown that territorial variation, i.e., the region of the country, had no effect on this issue. The identification of socio-demographic determinants of the ecological nature of decisions related to the choice of heating devices in single-family houses in Poland fills the research gap and thus contributes to the literature in this area.
