Design of retrofit flue gas (CO2) scrubber for dependable clean energy at the Duvha Coal Power Plant

The coal-fired power sector is facing unprecedented pressure due to the shift to low-carbon energy sources and the need to prevent climate change. It is imperative to incorporate advanced technologies into conventional coal-fired power plants to enhance their efficiency, flexibility, and environmental sustainability. One advantage of post-combustion CCS methods is that they may be retrofitted into power plants that are already in place. The goal of this work is to design a CO2 flue gas cleaning retrofit system that will meet the most stringent air quality regulations in an operational coal power station in Southern Africa. It will operate and expedite the removal of undesired gas (CO2) in order to attain ideal requirements for air quality in one of Southern Africa's current coal-fired power plants, the Duvha Coal Power Plant. This study is based on chemical absorption, and explores the mechanistic design of the scrubber, which was accomplished through simple computations and Ansys simulations. The approach for developing a wet CO2 scrubber and LSTG system is based on chemical absorption and is integrated with a pilot plant. The results of the parametric study provide a foundation for a comprehensive industrial system design for South Africa's coal-powered industry. The results show that the scrubber's cylinder height and diameter can be used for an LSTG system and are appropriate for CO2 gas flow and capture. The application of the suggested scrubber design and the LTSG's contributions will allow the coal power station to operate with minimal GHG emissions released into the atmosphere. Instead of shutting down coal power facilities, this cleaning system that completely absorbs CO2 emissions can be used to maintain a robust power infrastructure, rather than being phased out. This will boost the power plant's efficiency over its initial operating efficiency and benefit the nation's economy and the power industry.

The article summarizes the public debt policy issues in the context of financing climate change measures, and suggests priorities and mechanisms of fiscal, debt and sectoral policies to ensure sufficient financing of the green agenda. Authors have emphasized the trilemma between achieving climate goals, maintaining fiscal sustainability, and ensuring political capacity. It has been found that even under favorable external financial conditions, climate-vulnerable countries face a constant premium to the cost of borrowing. As a result, developing countries with high levels of debt and climate vulnerability are caught in a vicious circle of growing investment needs for climate- sustainable structural transformation and significant dependence on increasingly expensive debt financing, which leads to a combination of deteriorating debt sustainability and insufficient funding for climate change challenges. Authors argue for a comprehensive multilateral policy aimed at reforming the international debt architecture and increasing the amount of available financing for climate change adaptation under a government-led framework. Achieving common goals requires a carefully calibrated combination of climate change mitigation instruments based on enhanced domestic revenue mobilization, in particular through carbon pricing, more efficient spending on transfers, green subsidies and investments, and regulatory measures. Authors propose a comprehensive approach to implementing climate change mitigation policies, including the implementation of a fiscal strategy, sectoral policies to prevent climate change, and stimulating private investment. Emphasized the importance of developing further tools for incorporating climate policy into debt sustainability analysis.

Thermodynamic functions and parameters of sorption from flue gases (CO2,SOx,NOx) by Khekordzula clinoptilolite

Generation during the production process and emissions into the atmosphere with flue gases (CO2,SOx,NOx) cause the “greenhouse effect” and the problem of global warming. Despite the existing practice of using zeolite as an adsorbent for a number of gases in projects such as Carbon Capture, Utilization and Storage to prevent climate change, the thermodynamic functions and parameters of the zeolite tuff containing the mineral Khekordzula clinophtholite in the inner Kartli region of Georgia are unknown and have not been studied. According to the research data, the corresponding thermodynamic parameters were determined, namely the enthalpy of formation of the mineral clinophthylolite in the Khekordzula zeolite tuff ΔfH2980=−39,825.838kj·mol−1, Gibbs energy ΔfG2980=−36,734.784kj·mol−1, entropy S2980=−10.373j·K·mol−1; Dehydration and as well as physical sorption (CO2, SOx, NOx) start parameters: temperature T=352.90K, pressure P=6.84mmHg. The thermodynamic parameters of the Khekordzula natural clinoptilolite tuff, taking into account its basic mineralogical composition, were determined: ΔfH2980=−30,403.76kj·mol−1; ΔfG2980=−29,963.01kj·mol−1; S2980=−1.48j·K·mol−1; T=374.22K, P=0.0003mmHg. It has been confirmed that chemisorption (CO2, SOx, NOx) by Khekordzula clinophthylolite should begin at temperatures above 2000 K. The results of the conducted studies make it possible to evaluate the prospects of using Khekordzula and natural zeolites of similar composition as an adsorbent for harmful industrial gases, which will help plan and implement effective solutions to environmental problems.

The originality of our study derives from the proposal of a set of renewed streams of research addressed to academics and practical communities as well as to decision‐makers and policymakers in taking urgent action to be compliant with emerging legislative issues and to be accountable toward stakeholders in preventing climate change and combating environmental impacts.

An Exploration of the philosophical values in Western and Eastern traditions: Implications for our understanding of nature

Climate change has become one of the most critical issues in global politics. Despite extensive deliberations among world leaders under the United Nations, no definitive conclusions have been reached. The Kyoto Protocol proposed a top-down approach for states to combat climate change, placing the responsibility for reducing the carbon footprint on the state machinery. However, with the failure of this approach, the world community introduced the Paris Agreement, which adopted a bottom-up approach to combating climate change. This approach aimed to appeal to the consciousness and morality of each human being in addressing climate change by raising higher questions of human existence rather than focusing solely on material needs. The higher questions of human existence are situated in the religious teachings, values and beliefs of the different faiths of the world. The paper seeks to explore the variations in the intrinsic values as proposed by the East and Western philosophies about the world and the role of individuals within the universe. By analysing those values, the paper seeks to explore how such philosophical principles can invoke their reverence for nature among individuals. Such an outlook can encourage people to embrace those notions in their daily lives and thus modify their lifestyle patterns to prevent climate change.

AimThis research aimed to determine nurses’ climate change worry, their level of hope for climate change prevention, and the relationship between climate change worry and hope for climate change.BackgroundNurses are healthcare professionals actively involved in the fight against climate change. However, their close involvement with the issue can also increase their own climate change worry. Therefore, it is important to maintain high levels of hope among nurses in preventing climate change.MethodsThis descriptive cross-sectional study was conducted with nurses working at a university hospital.ResultsThe average score on the Climate Change Worry Scale for nurses was 29.22 ± 9.33, with sub-dimensions scores as follows: personal-sphere will and way 10.96 ± 2.09; collective sphere will 18.36 ± 3.39; lack of will and way dimensions 10.40 ± 2.48. The average score on the climate change hope scale was 39.73 ± 5.52. A statistically significant positive relationship was found between age and the climate change worry scale (r = 0.169, p = 0.020) as well as climate change hope (r = 0.148, p = 0.041).ConclusionThe research findings indicate that nurses have a high level of climate change worry, but they also have a high level of hope in preventing climate change. It is considered essential to address the concerns of nurses who are actively combating the climate crisis.

Sustainable Development of European Countries: The Climate Component

This article provides a cause-and-effect analysis of the impact of carbon emissions on climate change and on the sustainable development of European countries. Despite the consolidated efforts of the world community, the global amount of greenhouse gas emissions is not decreasing, leading to irreversible climate change. The objective of this paper is to explore Europe’s progress towards climate neutrality in the context of ensuring sustainable development and achieving the goals of the European Green Deal. The article aims to establish an econometric relationship between the amount of carbon emissions and the energy intensity of GDP based on statistical data from European countries, and using the example of Ukraine during a full-scale invasion to demonstrate factors that influence greenhouse-gas- emissions growth despite GDP. A significant aspect of this study is an analysis of data from 2012–2022, which indicates that Europe has reduced CO2 emissions and is successfully moving towards climate neutrality. Key efforts of EU countries in preventing climate change and transitioning to renewable energy sources are reflected in the context of the Green Deal. Based on econometric calculations, the direct relationship between the amount of carbon emissions and energy intensity of GDP in European countries was confirmed with a probability of 0.95. The obtained interdependence allows one to predict the amount of CO2 emissions based on known values of energy intensity of GDP during stable economic development. Special attention was paid to Ukraine and the increase in CO2 emissions due to the war. The authors concluded that the war disrupted the relationship between GDP and CO2 emissions, leading to a 23% increase in emissions in 2022. Overcoming the climate crisis and ensuring sustainable development requires a global decarbonisation strategy. However, effective climate policy is impossible without achieving peace.

Meeting the Energy Needs of Poultry Houses with Wind Turbine System under Tekirdağ Conditions and Its Environmental Effects

Türkiye has a favorable geographical location for renewable energy sources such as wind and solar. Accordingly, renewable energy sources can be used in the fast-growing bovine, ovine, and poultry farms that perform plant and animal production. Marmara Region is the leading production center of the Turkish poultry production industry. However, there are problems in maintaining environmental conditions in poultry houses. The fan-pad system plays an essential role in maintaining environmental conditions in the poultry houses. For this reason, the fan-pad system required for evaporative cooling in the poultry houses in Tekirdağ region was designed. The project was carried out in poultry houses with 6000 chickens and the dimension of the poultry house is 14 x 30 (420 m2). In the poultry house, a 16.8 m2 pad is needed for cooling, and a circulation pump with 0.2 kWh power is required for water circulation in the system. For mechanical ventilation, 11 units of aspirators with a diameter of 60 cm a power of 0.75 kWh, and a flow rate of 9500 m3h-1 will be sufficient for the system. For the ventilation and cooling system, an 8.45 kWh wind turbine system will supply the required energy. However, due to the variability of wind power, a turbine system larger than 8.45 kWh, such as 10 kWh, should be used. The cost of the cooling system planned with the wind turbine energy system reaches 35953 $. The use of wind turbine systems to generate electricity in agriculture will significantly reduce CO2 emissions to nature. In Tekirdağ conditions, 18250 kWh of electricity can be produced annually with a 10-kWh wind turbine system. With eco-friendly energy generation, it can play a major role in preventing climate change by avoiding the emission of 17155 kg of CO2 which is equivalent to the annual electricity production.

Individual and Collective Approaches of Students who are Members of Social Clubs at University to Mitigate Climate Change Impacts

Climate change is one of the most important global problems of our time. For the solution of this problem, the need for awareness and taking responsibility at individual and social level is quite high. The aim of this study, which was conducted on social club members, is to examine the level of hope for the prevention of climate change according to sociodemographic characteristics, club factors and taking responsibility variable. Relational survey model, one of the quantitative research methods, was used in the study. The research data were collected from the students studying at Ardahan University in the 2023-2024 academic year through a questionnaire. The data obtained were analyzed using SPSS 27 and AMOS 24 statistical package programs. In this context, parametric tests such as Independent Samples T Test, One- Way Analysis of Variance (ANOVA), Pearson Correlation and Simple Linear Regression Analysis were applied due to the normal distribution of the data. When the results of the analysis are examined, it is seen that the mean scale scores of the sample group are high; there is a significant difference between the groups in terms of hope levels according to their education levels and club types; and the variable of taking responsibility has an effect of 26.7% on the level of hope. Thus, a one-unit increase in the level of responsibility causes a 0.301-unit increase in the level of hope for preventing climate change. In this context, club members' approaches to preventing climate change can be strengthened by conducting incentive studies to increase their sense of responsibility.

Vulnerability and adaptation of maize smallholder farmers to climate change: a Sub-Saharan African context

This study analyzed smallholder maize farmers' perceptions of climate change vulnerability and adaptation strategies in the eastern Democratic Republic of the Congo. The study used a cross-sectional quantitative approach, with smallholder farmers selected based on farm size (less than 10 hectares). Using simple random sampling techniques, 210 smallholder farmers in South Kivu Province was selected from October and November 2021. The data were analyzed using frequency analysis, non-parametric Mann–Whitney U-tests, Tobit regression model and structural equations modeling, which demonstrated that demographic and socioeconomic factors influenced smallholder farmers' perceptions and adaptation strategies to climate change. The findings revealed that the level of education, size of the field, and activities of smallholder farmers had significant effects on climate change perception and adaptation strategies. Smallholder farmers' perceptions had a negative (p < 1%) influence on maize smallholder farmers' adaptation to climate change. Common efforts should be made to encourage smallholder farmers to feel committed enough to implement climate change adaptation measures that are effective in mitigating or preventing climate change risk. The results of this study would have implications for policies to support maize smallholder farmers in their efforts to mitigate and resilient to climate change in sub-Saharan Africa. Firstly, the promotion of climate literacy must be sufficient to provide farmers with information on climate and forecasting. Secondly, to empower smallholder farmers with means and resources to prevent and reduce the effects of climate change. Lastly, enhancing the current environment for the agriculture sector will advance community inclusivity and food security.

Prospects for the development of legal regulation of Green Recovery in Ukraine

Ukraine has committed itself to developing and implementing long-term measures aimed at reducing greenhouse gas emissions. As a party to the Paris Agreement to the United Nations Framework Convention on Climate Change, the state is obliged to make its nationally determined contribution to achieve the goals of sustainable low-carbon development of all sectors of the economy and increase the ability to adapt to the adverse effects of climate change. The official announcement of joining the European Green Deal demonstrates Ukraine’s unwavering intention to overcome the challenges posed by climate change and environmental degradation by transforming into a modern resource-efficient and competitive economy. In June 2022, Ukraine was granted the status of a candidate for EU membership. These measures should be implemented despite Russia’s anti-Ukrainian armed aggression and difficult economic challenges.&#x0D; The purpose of this work is to determine the main directions of development of the legal mechanism for preventing climate change, which is being formed in the context of military realities, while ensuring that Ukraine strictly complies with its obligations under the European Green Deal.&#x0D; It is concluded that when developing the conceptual legal framework of the environmental security component as part of the Strategy for Post-War Recovery and Development of Ukraine and the relevant Action Plan, as well as sectoral programs for the restoration of the State, an appropriate climate policy should be formulated, coordinated with Ukraine’s further European integration.&#x0D; These include updated priority measures of the national climate policy, broad state support for environmental protection measures; digitalization of environmental relations; provision of funding for measures and investments aimed at developing competitive renewable generation and improving existing infrastructure, developing the potential of the hydrogen ecosystem, increasing the energy efficiency of buildings through the integration of renewable energy sources, decarbonizing insulation and cooling of buildings, ensuring the development of transport with low.

Different mobility solutions are stated in this document. The use of electric vehicles, Passenger Information Systems, Car-sharing and ride-sharing services, electronic payment, Bus Signal Priority, and Vehicle-Integrated Photovoltaics. Using photovoltaics in Rwanda is adequate because of the electricity problem. This is the best solution for fighting against climate change due to fuel from motorized traffic.

Análisis Multitemporal de Distribución Geográfica Potencial del LamaGuanicoe

The purpose of this research is focused on modeling the geographic distribution of Lama guanicoe in South America in two time periods, 2021 and 2070, using MaxEnt software to correlate the bioclimatic variables and calculate the change in the distribution area. Then, with this information, a comparative map of the current and future areas was made in QGIS. As conclusions we can see that in the region of Peru the change of distribution area is reduced, which is observable in the majority of the nations where the guanaco (Lama guanicoe) lives, which is currently considered Endangered, so according to our model it predicts that it will reduce the distribution area by 20%, and the temperature variables have a negative correlation with the area, which indicates that climate change will have a relationship with the Lama guanicoe. This information is necessary for all countries to take action in the conservation of Lama guanicoe by adopting strategies to reduce and prevent climate change, generating and updating their conservation plans.

Short-term impact of climate change on labor market in China: Quantitative spatial analysis based on an oligopsony model

Assessing the impact of climate change on the economy is an important issue for designing climate policy. By constructing an oligopsony model to depict the incompleteness of the labor market and using the quantitative spatial model analysis method, we quantitatively estimated the short-term impact of climate change on the labor market in China. Then, to control climate change, the optimal climate change governance intensities (CCGI) of multi-governments satisfying CD preferences and Stackelberg game are designed and solved. The results show that climate change leads to a decrease in wages and labor supply in labor market equilibrium and a loss of market aggregate income and labor scale. Climate change has led to a shift in labor from the agricultural and dirty sectors to the clean sector. The regional labor distribution is also being “disrupted” due to climate change. Moreover, declining migration costs and increased subsidies help to reduce the negative impacts of climate change. The optimal CCGI of the central government is higher than that of the provincial government. The optimal CCGI is higher in the eastern provinces than in the central and western regions. Implementing CCGI would mitigate the negative climate change shocks to the labor market in China and increase welfare. The conclusions of this paper provide strong support for preventing climate change risks and actively participating in global climate change governance.
