Special Issue Information

Dear Colleagues,

Industrial human activity has resulted in increased emissions of carbon dioxide into the atmosphere, which has caused global climate warming and an increased threat to the environment and human livelihood. The unbalanced model of traditional energy use causes ecological systems to be destroyed, and many plants and animals cannot cope with the changing reality and simply die. Hence, the goal of the global energy system should be a gradual transition from fossil energy to low-carbon energy. Reducing greenhouse gas emissions such as carbon dioxide should be a goal of all, not just a few, economies in the world. The development of energy systems towards low-carbon, energy-efficient and highly renewable solutions is a top priority for the global community. The new environmental conditions caused by changing climate require decisive action and the introduction of innovative solutions supported by political decisions to achieve the goal of global carbon neutrality. The basis of this strategy is the efficient use of water, land and natural energy sources, which is related to rational and sustainable water and waste management, spatial and land-use changes, continuous reduction of greenhouse gas emissions, a transition to renewable energy production and reduction of fossil resources. Many key issues related to the dissemination and implementation of new green energy technologies require further clarification. Hence, research on new directions of energy development and acquiring low-carbon energy are of great importance for achieving sustainable and ecological energy use in the future.

The Special Issue “Energy Transitions: Low-Carbon Pathways for Sustainability” calls for an in-depth discussion on the future directions of low-carbon development in the energy industry, which will affect the adaptation of the energy structure, sustainable development and circular economy. Original scientific articles and reviews are welcome in this Special Issue.

We look forward to receiving your contributions.

This paper proposes a practical framework for developing a net-zero electricity mix scenario (NEMS), which considers detailed conditions for supply of each energy. NEMS means a path scenario for power generation amount by year of each generation resource required to achieve carbon neutrality in 2050. NEMS framework refers to a methodological framework that contains procedures and requirements to continuously update the NEMS by comprehensively reflecting policy changes. For evaluation of NEMS, indicators such as a system inertia resource ratio (SIRR) and a fuel conversion rate (FCR) are proposed. The proposed framework and indicators are applied for the 2050 NEMS in Korea’s electricity sector. The SIRR, indicating the ratio of inertial resources to total resources, projects values of 49% and 15% for the years 2030 and 2050, respectively. Furthermore, the FCR, reflecting the ratio of fuel conversion for resources undergoing this process, predicts that all targeted resources will have completed conversion by the year 2043. Full article

Increasing the proportion of carbon-free power sources, such as renewable energy, is essential for transitioning to a zero-carbon power system. However, when the rate of grid expansion and flexibility cannot match the rate of renewable energy increase, surplus energy is the result. Surplus energy can be discarded through curtailment or stored and utilized when required. The optimal equipment configuration of the storage system should be determined based on the surplus energy characteristics. This study proposes an optimal energy storage mix configuration method by considering long-term forecasts of surplus energy in the South Korean renewable energy supply and power grid expansion plan. The surplus energy by time slot is comprehensively analyzed considering renewable energy power output, power demand, and power system operation constraints. We calculate the required power and energy of storage devices. Furthermore, we construct a long-term optimal energy storage mix using surplus energy generation patterns and technical and economical characteristics of storage technologies. The total cost minimization was considered as the objective function, comprising three elements: initial construction, equipment replacement, and loss costs for charging and discharging. We propose a time sequence analysis (TSA) method that enables chronological analysis from the starting year to the final target year. The TSA method provides an energy storage mix configuration roadmap that can utilize surplus energy for various years over the entire period, considering the annual increase in surplus energy and commercialization timing of each storage technology. We compare the difference between our proposed TSA method and the method that analyzes only the final target year to validate the superiority of this methodology. Full article

The Sixth Assessment Report of Inter-Governmental Panel on Climate Change (IPCC) has highlighted the urgency of accelerated climate actions harnessing synergies and minimizing trade-offs with various SDG. This calls for a clear understanding of linkages between climate goals and other SDGs at national level for formulating synergistic policies and strategies and developing different sectoral programs and coherent cross-sectoral policies. This is even more important for least developed countries such as Nepal where these linkages are less understood and development challenges are multifaceted. In this context, this paper aims to evaluate potential synergies and trade-offs among selected SDGs and their associated targets in Nepal in a linear pairwise comparison. Synergies and trade-offs related to climate action (SDG 13), access to energy (SDG 7), sustainable consumption and production (SDG 12), and life on land (SDG 15) have been evaluated using historical data for the period from 1990 to 2018 employing a mixed methods approach. Network analysis to map the conceptual linkages between the SDGs and their targets was combined with the advance sustainability analysis (ASA) to quantitatively evaluate the synergy and trade-offs between SDGs. The results illustrate the presences of a continual trade-off between emission reductions targets of SDG 13 with per capita energy consumption and share of renewable energy of SDG 7, land use for agricultural production target of SDG 12, and forest area target of SDG 15. This indicates that climate action is strongly interlinked with GHG emissions from economic activities and energy consumption. The results of the study represent a valuable input for the policy makers, supporting coherent and sustainable development planning as Nepal plans to graduate to a middle-income country. Full article
