The Opportunities and Challenges of Digital Technologies in Energy Systems To Reduce Ghg Emissions
(Springer Nature, 2025) Dinçbaş, T.; Kuzu, A.; Ergeneli, A.; Çelik, D.
Since the problems caused by the global climate crisis threaten the lives of all kinds of living creatures, it has brought to the agenda the need to reduce the greenhouse gas emissions that cause it as quickly as possible. Reports published by international organizations and researchers draw attention to the urgent need to use renewable energy sources instead of fossil fuels in energy systems and digital technologies to ensure energy efficiency and control to reduce greenhouse gas emissions. Emphasizing the necessity of using digital technologies in energy systems by highlighting their impact on reducing greenhouse gas emissions causes digital technologies to be the leading actor in solving the global climate crisis. On the other hand, studies show that digital technologies have more challenges than expected. However, these studies, which are few, do not attract enough attention. Being aware that digital technologies in energy systems provide challenges and opportunities will lead to more rational investments in digital technologies. Therefore, this study aims to review articles that evaluate the opportunities and challenges provided by digital technologies in energy systems and contribute to the literature by presenting a survey that examines them together. For this reason, 21 current studies examined and determined that challenges should be taken seriously in addition to the opportunities provided by digital technologies. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
Strategic Deployment of Hydrogen With Nuclear-Renewable Synergy: Pathways to Carbon Neutrality and Sustainable Development Goals
(Institute of Electrical and Electronics Engineers Inc., 2025) Çelik, D.; Goyal, S.K.
This work explores the combination of nuclear-renewable hybrid systems and hydrogen production as a pathway to reach carbon neutrality and support the objectives of sustainable development goals (SDGs). The proposed system integrates nuclear energy, a photovoltaic (PV) system, and wind energy to deliver a consistent and dependable clean energy supply. The assessment examines the system's economic viability by analyzing critical financial indicators, including NPV and IRR, under different scenarios. These scenarios include revenue from both energy production and hydrogen and oxygen sales, which significantly enhance profitability. This study highlights the synergy between wind and PV power, where their complementary generation patterns - wind often peaking at night and solar during the day - reduce variability and maximize energy utilization. Hydrogen integration further strengthens financial performance by adding flexible energy storage and offering additional revenue streams from hydrogen sales, especially during periods of excess energy generation. This enhances grid stability, reduces curtailment, and supports decarbonization efforts. The results highlight the critical role of well-designed policy frameworks, financial incentives, and technological progress in reducing expenses and tackling key obstacles, including the substantial upfront investments and infrastructure needs associated with hydrogen production and storage. © 2025 IEEE.
Trends and Developments of Electric Vehicles: Current State and Future Perspectives
(Springer Science and Business Media Deutschland GmbH, 2024) Çelik, D.
Increasing transport electrification results in more charging stations with outstanding impacts on the electricity networks. Therefore, various charging approaches as well as grid integration strategies are being enhanced to reduce the adverse impacts of EV charging and to promote the profits of EV grid integration. Maximizing the advantages of EVs with smart charging infrastructure, distributed generators, and reliable communication systems is critical to measuring effects on the electrical grid. With the increasing importance given to this area, this paper addresses the current EV status and investigates an extensive overview on significant international EV charging and grid interconnection standards. The characteristics of the EV technologies are investigated and discussed. The main charging techniques, battery technologies, and charging standards are overviewed and discussed. Some results based on registrations of the EVs, battery demand, and electric cars including battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), and plug-in hybrid electric vehicles (PHEVs) are analyzed and examined. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024
