Implications of coal disappearance from the energy mix in Romania

MATEC Web of Conferences, 2022

The firm commitment of the European Union (EU) to fully implement the 2030 Agenda requires the Member States to find and implement solutions to meet global targets, including ensuring clean and affordable energy. The EU encourages the elimination of coal from the energy mix in order to quantitatively reduce emissions and the impact on the environment and human health. Romania attaches great importance to the 2030 Agenda and understands that developing the national economy, increasing the quality of life, and caring for the environment are inextricably linked to the development and modernization of the energy system, for which the National Energy Strategy 2019-2030 was developed. According to it, in the perspective of 2050, Romania will be based on a diversified, balanced, and modern energy mix through clean technologies. But what if coal would disappear from the energy mix? The causes of the disappearance of coal from the energy mix could be represented by global or national policie...

Restructuring of coal mining in Romania between the climate crisis and the energy transition

MATEC Web of Conferences

The Romanian energy market is dependent on about a third of total production on the use of fossil fuels, hard coal and lignite and natural gas, especially in the winter months or dry summers, coal still being of strategic importance in producing electricity and ensuring energetic security. However, the sharp changes in climate in recent years have led to the conclusion of environmental agreements, with objectives aimed at long-term strategies to reduce greenhouse gas emissions and which clearly require a reduction in the capacity to produce one kilowatt of thermal energy and identify solutions for transition to clean energy. Where will the Hunedoara Energy Complex and the Oltenia Energy Complex be located in this context? This paper aims to analyze the process of restructuring coal mining, the competitiveness of coal in the electricity mix and possibly the future prospects of restructured mining areas.

Coal Based Electricity Generation in South East Europe

2016

ABSTRACT: In this paper, we have provided an evaluation of the techno-economic performance of a coal-fired power generation unit designed and constructed following the current best available techniques (BAT) principle and situated in South East Europe (SEE). We have provided the framework of a technical model of an ultra supercritical pulverized coal-fired power plant (USC or USCPC), conducted a detailed analysis of associated costs, presented a composite cost model and performed a sensitivity analysis to identify the main cost-drivers for this type of technology. Furthermore, a market analysis has been carried out to best determine the impact of the surrounding environment on the overall performance of the project.

Coal supply prospects in Poland and Selected European Union Countries

Gospodarka Surowcami Mineralnymi – Mineral Resources Management, 2021

The raw material economy determines energy security for individual countries in the world. Coal is one of the most important energy carriers for electricity production and heat generation. World market trends of fossil raw materials such as hard coal and lignite were presented. In the European Union a significant decrease in coal and lignite consumption has been observed in recent years. This situation is primarily related to the accelerating decarbonisation policy and support of renewable energy sources, which are considered to be environmentally friendly. The pandemic occurring in recent years has also played an important role in shaping the raw materials market. The author shows the possibilities and directions in which the coal economy has prospects for development and expansion. The amount of the world’s coal resources is presented, as well as the size of the global consumption of the raw material in the 2000–2011 years, specifying in China, India, Asia, the USA and the countries of the European Union. The structure of the coal economy is presented in the light of the policies and laws enacted by the European Union Comission, in particular in Poland, Germany and France. The appearance of the hard coal sector and lignite sector in Poland is described in detail. The size of resources was given in terms of coal classification. The presented data were based on a range of information and reports from world organizations such as the International Energy Agency or British Petroleum.

The perspectives of energy production from coal-fired power plants in an enlarged EU

International Journal of Energy Research, 2004

The aim of this paper is to present the current status of the coal-fired power sector in an enlarged EU (EU-15 plus EU member candidate states) in relation with the main topics of the European Strategy for the energy production and supply. It is estimated that 731 thermoelectric units, larger than 100 MW e , are operating nowadays, and their total installed capacity equals to 200.7 GW e . Coal contribution to the total electricity generation with reference to other fuel sources, is by far more intensive in the non-EU part (EU member candidate states), compared to the EU member states. It is expected that even after the enlargement, the European Union will strongly being related to coal. Enlargement will bring additional factors into play in order to meet the requirements of rising consumption, growing demand for conventional fuels and increasing dependence on imports. Besides the technology, boiler size, efficiency, age and environmental performance will determine the necessities of the coal-fired power sector in each country. Depending on the case, lifetime extension measures in operating coal-fired power plants or clean coal technologies can play an important role towards the energy sector restructuring. Low efficiency values in the non-EU coal-fired units and heavily aged power plants in EU countries will certainly affect decisions in favour of upgrading or reconstruction.

The Impact of Coal Mining Reduction on the Energy MIX of Poland

Humanities and Social Sciences quarterly, 2017

The article is aimed at assessing the impact of reducing coal mining on the energy mix of Poland. Taking into account the current economic situation in the mining industry and its key role in the raw material economy of the country, the authors have attempted to assess the impact of the reduction the size or abandoning the production of hard coal mining in Poland on the situation in domestic energy sector and to present some of the resulting consequences. It is important that the share of coal in the national energy mix decreases each year, mainly in favor of natural gas and renewable energy sources. The wind power share in energy systems is increasing each year. This situation takes place both worldwide and in Poland. This development is a result of introducing requirements dictated by the conduct of climate policy. The energy solutions, which have a positive impact on the environment and climate change are mainly supported. However, it should be noted that in 2015 more than 50% of electricity was generated from burning hard coal in power generation plants. The vast majority of Polish power plants are hard coal fired power plants. A much smaller number are power plants powered by another type of fuel, including power plants powered by renewable energy sources. Currently, new capacities based on this fuel, i.e.: Kozienice, Jaworzno, and Opole power plants, are being built. The abovementioned conditions and the results of detailed analysis indicate that hard coal will continue to be used in Poland for many years.
