“…The term "blackout" is used to describe a sudden and severe failure of the power system, resulting in a loss of electricity over a large area. Usually, a blackout is understood as a prolonged power outage, even for several days [3,4]. The main causes of blackouts are as follows:…”

Global warming increases the risk of power outages. Mine water pumping stations pump approximately 100 million m3 of water per year (2023). The cessation of mine water pumping would expose neighboring mines and lower lying areas to flooding. The pumping stations have some containment, but a prolonged shutdown could cause environmental problems. Remediation of the resulting damage would be costly and time-consuming. The combination of the problems of dewatering abandoned mines and storing energy in the form of hydrogen to ensure continuity of power supply to pumping stations has not been the subject of extensive scientific research. The purpose of this paper was to develop options for protecting mine water pumping stations against the “blackout” phenomenon and to assess their investment relevance. Six technically feasible options for the modernization of mine water pumping stations were designed and analyzed in the study. All pumping station modernization options include storage of the generated energy in the form of green hydrogen. For Q1 2024 conditions, the option with the partial retail sale of the produced hydrogen and the increased volume of produced water for treatment is recommended for implementation.

“…Moreover, carbon dioxide capture, utilisation and storage (CCUS) belongs to the technologies that can play an important role in achieving global energy and climate goals (IEAGHG, 2017;Smoliński et al, 2021;Tokarski et al, 2021). CCUS involves CO 2 capture from large emission sources, including power plants or industrial facilities that use fossil fuels or biomass as fuel; CO 2 can also be captured directly from the atmosphere.…”

“…The availability and recognition of suitable geological formations and structures for underground CO 2 storage still remain the key factors which limit the possibility of using CCS technology in climate plans. The selection of a suitable underground geological formation for permanent CO 2 storage must be preceded by a detailed characterisation and assessment of the potential storage reservoir and the surrounding rock mass (Buscheck et al, 2012;Tokarski et al, 2021). The characterisation of the dynamic behaviour of carbon dioxide stored in the rock mass is an important step in the process of evaluating a potential CO 2 reservoir (Kumar et al, 2020).…”

In this study, dynamic simulation models of CO2 injection into saline aquifers of the Choszczno-Suliszewo structure located in north-western Poland were constructed for two scenarios with different injection rates. The injection rates of 1 Mt CO2/year and 2 Mt CO2/year were analysed for each of the injection wells. Changes in pressures, characteristic for the sequestration process, were analysed; in addition, the spatial distribution of free CO2 saturation in the structure and carbon dioxide dissolved in brine were presented in a graphical form. The observation time of changes occurring in the rock mass in the interval of up to 1,000 years after the completion of injection was assumed. During the modelling of CO2 sequestration in Lower Jurassic aquifers in the Suliszewo model, the previously assumed CO2 injection rates were achieved for both injection scenarios. The observed pressure increase does not pose any threat to the Suliszewo structure tightness. The sequestration process was found to be highly effective due to the phenomenon of the dissolution of CO2 in brine and the resulting convection motion of brine enriched with carbon dioxide. Consequently, there is an increase in CO2 storage capacity and permanent long-term trapping of the injected carbon dioxide. The process of the displacement of injected CO2 from the collector layers to the layers constituting the reservoir sealing was observed. This phenomenon takes place in the upper parts of the Choszczno structure and is caused mainly by the locally occurring worse technical parameters of seal layers in this area.

“…The assumptions of the idea of sustainable development and the efficient use of resources are implemented in many cement plants in Poland and around the world through the partial substitution of clinker in cement with raw materials of anthropogenic origin (such as ground blast furnace slag from iron ore production [2,3], fly ash from coal power plants [4], or gypsum waste [5]), and the use of alternative energy sources (i.e., fuel from waste instead of high-emission fossil fuels) [6][7][8][9]. Waste management is one of the most significant challenges of the modern world due to the amount of waste generated and its complex and unstable composition [10,11].…”

The use of waste as an energy source in cement clinker production is a promising way to transition toward a circular economy and limit carbon dioxide (CO2) in the atmosphere. The cement industry is responsible for around 5% of global CO2 emissions. In this paper, the analysis of environmental and economic profits associated with the substitution of coal by two refuse-derived fuels (RDF) and sewage sludge (SS) in a cement kiln was presented. Differences in the fuel-related CO2 emissions were calculated for two-, three-, and four-component fuel blends based on the fuel consumption data, heating values, and the correspondent emission factors. The biogenic fraction content of 19% and 43% were measured in RDFs. The material balance of fuels with the assumed technological parameters of the cement clinker production installation (capacity of 6000 Mg per day and unit heat of 3.6 GJ) shows that the RDF heat substitution at the level of 90% allows for a saving of approximately 28.6 Mg per hour of coal, and to manage even approx. 40 Mg per hour of RDF. The increase in the share of SS in the total heat consumption to 6% contributed to reducing the actual emissions by 17 kg of CO2 per 1 Mg of clinker. Multilateral benefits due to the use of RDF in the cement plant were evident.
