Abstract Industrial parks may be high pollutants of the local environment, but also engines of regional development, employment, and economic value added. To make them more sustainable, regional planning often purports to promote a transition to a greener approach, but in reality, many green measures oppose business logic and profitability, while those companies that do invest in sustainable solutions do so without having a clear strategy. This complicated setup is to be explored and modelled in this article which is focused on a remarkable area, the urban region of Székesfehérvár, an industrial city in Hungary having an impressive economic development and hosting significant domestic and international companies. The disharmony between greening policies, intentions and actions is observable in Székesfehérvár, despite the considerable local and regional potentials of renewable energy resources. Findings indicate that systemic thinking and future-oriented decision making will be necessary to achieve true sustainability, which also requires a mutually proactive attitude and the cooperation of different sectors. A legitimate strategy aiming at greening the local and regional economy (with renewable energy concerns), implemented by both public and business actors can be the key element of a successful transition. This strategy needs to be stimulated by local governance.

Abstract Rising atmospheric CO2 levels from significant imbalance between carbon emissions from fossil fuel utilization, especially for energy and chemicals, and natural carbon sequestration rates is known to drive-up the global temperatures and associated catastrophic climate changes, such as rising mean sea level, glacial melting, and extinction of ecosystems. Carbon capture and utilization techniques are necessary for transition from fossil fuel infrastructure to renewable energy resources to help delay the dangers of reaching to the point of positive feedback between carbon emissions and climate change which can drive terrestrial conditions to uninhabitable levels. CO2 captured from the atmosphere directly or from flue gases of a power plant can be recycled and transformed to CO and syngas for use as energy and value-added chemicals. Utilizing renewable energy resources to drive CO2 conversion to CO via thermochemical redox looping can provide a carbon negative renewable energy conversion pathway for sustainable energy production as well as value-added products. Substituted ferrites such as Co-ferrite, Mnferrite were found to be promising materials to aid the conversion of CO2 to CO at lower reduction temperatures. Furthermore, the conversion of these materials in the presence of Al2O3 provided hercynite cycling, which further lowered the reduction temperature. In this paper, Co-ferrite and Co-ferrite-alumina prepared via co-precipitation were investigated to understand their potential as oxygen carriers for CO2 conversion under isothermal redox looping. Isothermal reduction looping provided improved feasibility in redox conversion since it avoids the need for temperature swinging which improves thermal efficiency. These efforts alleviates the energy losses in heat recovery while also reducing thermal stresses on both the materials and the reactor. Lab-scale testing was carried out at 1673 K on these materials for extended periods and multiple cycles to gain insights into cyclic performance and the feasibility of sintering, which is a common issue in iron-oxide-based oxygen carriers. Cobalt doping provided with lowering of reduction temperature requirement at the cost of oxidation thermodynamic spontaneity that required increased oxidation temperature. At the concentrations examined, these opposing phenomenon made isothermal redox operation feasible by providing high CO yields comparable to oxygen carriers in the literature, which were operated at different temperatures for reduction and oxidation. Significantly high CO yields (∼ 750 μmol/g) were obtained from Co-ferrite isothermal redox looping. Co-ferrite-alumina provided lower CO yields compared to Co-ferrite. The oxygen storage was similar to those reported in the literature on isothermal H2O splitting, but with improved morphological stability at high temperature, especially compared to ferrite. This pathway of oxygen carrier development is considered suitable with further requirement in optimization for scaling of renewable CO2 conversion into valuable products.

This panel study investigates the relationship between green logistics indices, economic, environmental, and social factors in the perspective of Asian emerging economies. This study adopted FMOLS and DOLS methods to test research hypothesis, catering the problem of endogenity and serial correlation. The results suggest that logistics operations, particularly LPI2 (efficiency of customs clearance processes), LPI4 (quality of logistics services) and LPI5 (trade and transport-related infrastructure), are positively and significantly correlated with per capita income, manufacturing value added and trade openness. While, greater logistics operations are negatively associated with social and environmental problems including, climate change, global warming, carbon emissions, and poisoning atmosphere. In addition, human health is badly affected by heavy smog, acid rainfall, and water pollution. The findings further extend and reveal that political instability, natural disaster and terrorism are also a primary cause of poor economic growth and environmental sustainability with poor trade and logistics infrastructure. Further, the application of renewable energy resources and green practices can mitigate negative effects on social and environmental sustainability without compromising the performance of economic growth. There is very limited empirical work presented in literature using renewable energy and green ideology to solve macro-level social and environmental problems, while this study will assist the policymakers and researchers to understand the importance of green concept in improving countries’ social, economic and environmental performance.

The aim of the work is to analyze possible ways of decarbonization of the EU heat supply sector. The task of the work is to identify the most promising areas and develop appropriate recommendations for Ukraine. The heat supply sector of the EU and Ukraine needs decarbonization, for which there is a big potential and different areas of implementation of relevant measures. In Europe, such a strategy is set out in the Roadmap for decarbonization of the EU heating sector until 2050, the main provisions of which are in line with objectives of the European Green Deal and the EU Strategy on Heating and Cooling. European experts have developed the concept of a smart energy system, which was taken into account when preparing the Roadmap for decarbonization of the EU heating sector until 2050. A number of carried out studies have shown that a smart energy system with 50% district heating integrated with other parts of the overall energy system is more efficient than a conventional energy system or the one based on decentralized heat supply, in terms of the possibility of using a high share of renewable energy. It is recommended for Ukraine to finalize the Concept of green energy transition until 2050, taking into account European approaches to the development of heating systems and the use of modern biofuels. It is also recommended to expand the current Concept of heat supply of Ukraine to the level of a strategy with an emphasis on the development of district heating systems, wide involvement of renewable energy sources and new technologies.

Abstract Renewable energy is the energy obtained from resources inexhaustible in the long term. Furthermore, in some countries, non-conventional renewable energy includes solar, wind, biomass, geothermal and mini-hydropower. The definition of mini-hydropower plants varies depending on the country. As an example, in Peru and Canada, mini-hydropower plants have different installing capacities, below 20MW and 50MW, respectively. Accordingly, this work (i) discusses the Energy Balance and challenges that renewable energies have to face on their way to the energy transition, (ii) highlights the forecast models to generate renewable energy in short-term energy planning. The historical data about the renewable energy resources and the energy produced have been obtained by COES. The R studio software was used for statistical analysis of renewable resources and electricity generation. Also, a forecast model was developed using a neural network to forecast renewable energy generation. The results show a strong correlation between hydro resources and non-conventional renewable energy resources. Finally, the data obtained from the renewable generation forecast model were used as input to carry out a short-term dispatch model using GAMS software to determine the forecast of daily marginal cost in SEIN.

Abstract Inherent in the continuous development of civilization is a constant increase in demand for electricity. The result of this situation could be a threat to cover domestic demand for electricity generated from domestic sources. It is significant therefore, to increase the energy security of the country, as well as to generate a positive impact on the development and dynamics of social and economic processes which is carried by the development of renewable energy sources. A crucial argument for the need to implement new sustainable solutions is growing environmental degradation and pollution resulting from the acquisition and use of non-renewable energy resources. Renewable energy resource for interest of this analysis is the wind. A crucial feature of the wind is its high volatility. Wind speed is characterized by diurnal, seasonal and long-term variation. The study area is Sosnowiec city. The analysis covers the data from the period 2002 - 2011 obtained using a meteorological station located in the Department of Earth Sciences, University of Silesia in Sosnowiec. Analyzed data are observations of wind speed measured at the height of 10m above the ground - average values of 10 minutes. The mean and maximum daily, monthly and annual values of wind speed have been calculated, and on their basis, a relevant analysis have been made. Average wind speed value for the analyzed area of the analyzed period (2002 - 2011) is 1,70m/s, while the maximum wind speed value is 3,78m/s. Sosnowiec is located in zone IV - unfavorable for the use of wind energy.

The aim of this study is to address the importance of strategic energy management in order to ensure the transition of Turkey, a country that is trying to end its dependence on energy, to green energy using renewable energy sources. With the excessive use of nonrenewable energy sources by Turkey, in order to reduce environmental pollution and foreign dependency in energy, it started studies to increase the use of domestic and renewable energy resources in the early 2000s. With the transition to renewable energy sources as a new concept in Turkey's energy policy “green energy,” it has come to the fore. With the transition to green energy, Turkey is trying to prevent pollution of the environment by reducing fossil fuel consumption and aims to reduce energy costs by reducing the use of energy sources that cannot be renewed in production. Turkey, a country rich in renewable energy sources, will be able to use existing renewable energy sources effectively and efficiently using strategic management in energy.

Owing to rising population and increasing energy demand, renewable energy resources become the most convenient and promising solution. Hence, solar power plant investments and photovoltaic module numbers have risen sharply. Turkey is one of the tight followers of the energy trends, thanks to its rising energy demand and economic power. However, the consequences of the massive plant wastes importance in term of economically and environmentally have not been understood yet. Almost 70% of the modules are formed by glass and the rest accumulates economically valuable metal materials, which are silver, aluminium and copper. These three main materials are substantially important in the overall waste. Not only the economic value, but also the environmental impacts of the mining effluents to excavate these metals are causing emission problems. As a chain reaction, the higher energy demand triggers a search for new and renewable energy resources. This is why popularity of solar energy has increased. Solar energy can be absorbed and transformed through photovoltaic modules, which contain glass and three main metals. In order to respond for the production of modules, metals are fundamental. This need triggers the need of metals mining excavations and emissions. In this respect, in the near future, thanks to the rising investments on photovoltaic modules and the CO2 emissions coming from mining, the wastes of photovoltaic modules and the need of recycling will become more important. That is why, in this study it is aimed to present environmental benefits and economic recoveries of recycling photovoltaic module in Turkey.

The lack of long-term financing, the low rate of return, the existence of various risks, and the lack of capacity of market players are major challenges for the development of green energy projects. This paper aimed to highlight the challenges of green financing and investment in renewable energy projects and to provide practical solutions for filling the green financing gap. Practical solutions include increasing the role of public financial institutions and non-banking financial institutions (pension funds and insurance companies) in long-term green investments, utilizing the spillover tax to increase the rate of return of green projects, developing green credit guarantee schemes to reduce the credit risk, establishing community-based trust funds, and addressing green investment risks via financial and policy de-risking. The paper also provides a practical example of the implementation of the proposed tools.

Renewable energy is considered the one of the most promising solutions to meet sustainable development goals in terms of climate change mitigation. Today, we face the problem of further scaling up renewable energy infrastructure, which requires the creation of reliable energy storages, environmentally friendly carriers, like hydrogen, and competitive international markets. These issues provoke the involvement of resource-based countries in the energy transition, which is questionable in terms of economic efficiency, compared to conventional hydrocarbon resources. To shed a light on the possible efficiency of green hydrogen production in such countries, this study is aimed at: (1) comparing key Russian trends of green hydrogen development with global trends, (2) presenting strategic scenarios for the Russian energy sector development, (3) presenting a case study of Russian hydrogen energy project «Dyakov Ust-Srednekanskaya HPP» in Magadan region. We argue that without significant changes in strategic planning and without focus on sustainable solutions support, the further development of Russian power industry will be halted in a conservative scenario with the limited presence of innovative solutions in renewable energy industries. Our case study showed that despite the closeness to Japan hydrogen market, economic efficiency is on the edge of zero, with payback period around 17 years. The decrease in project capacity below 543.6 MW will immediately lead to a negative NPV. The key reason for that is the low average market price of hydrogen ($14/kg), which is only a bit higher than its production cost ($12.5/kg), while transportation requires about $0.96/kg more. Despite the discouraging results, it should be taken into account that such strategic projects are at the edge of energy development. We see them as an opportunity to lead transnational energy trade of green hydrogen, which could be competitive in the medium term, especially with state support.

The authors test the hypothesis that there is a link between the consumption of non-renewable resources of the leading economies in the European region in terms of value-added industry and health. They performed a ranking correlation analysis on key indicators of population health and volumes of consumption of renewable and non-renewable resources in individual countries. The researchers assumed a slight relationship between the rate of healthy years of life and the production of renewable energy resources, making a positive contribution to the country’s environmental situation. Among the compared countries, those characterized by high consumption of primary energy resources are proportionally more productive and renewable energy resources. The analysis shows that differences in the health indicators of the regions’ population cause other more important factors than the studied ones. Some dependencies can be seen in analyzing the causes of death among the population of countries, for example, by cardiovascular diseases. The risk factor for this illness is air pollution caused by excessive consumption of non-renewable energy resources. The authors recommend considering the indicator of ecological footprint in the ratings of life quality in the regions. Compared to countries with lower welfare rankings, this parameter is too high for leaders. Under investigation, the authors considered the x3 weight for the health indicator in the Legatum Prosperity Index.
