Special Issue Information

Dear Colleagues, 

The role of renewable energy resources is indubitable to meet the global milestone of mitigated carbon and affordable clean energy for an environmentally sustainable world. Recent trends in the rapid production and integration of renewable energy sources such as solar, wind, geothermal, and hydro energy have stimulated the formation of distributed energy systems. Isolated and grid-connected microgrids are burgeoning to avail the propitious opportunities of these energy resources. The sporadic characteristic of renewables is of substantial research interest to the researchers, which are currently addressed by amalgamating single and hybrid energy storage systems. By virtue of cutting-edge power electronics, advanced control systems, and efficient algorithms, smart grids facilitate impeccable energy coordination and demand-side management, ensuring secure and stable grid operation in compliance with grid code and local policy. The integration of renewable energy resources is also thriving in electric vehicles, net-zero buildings, and sustainable manufacturing to alleviate climate change and eradicate carbon footprints. 

The transformation of the energy infrastructure requires substantial research in the technical aspects as well as from the perspective of the administration. The incorporation of the newer source of energies into the existing grid infrastructure necessitates several changes in policy and regulatory framework. Moreover, utility-scale penetration of renewable energies seems to be a serious challenge, given the highly unpredictable nature of the resources and limited adaptation and scalability of the current infrastructure. This special issue, therefore focuses on the urgent need for innovations and technologies in the domain of renewable energy engineering to disseminate these resources in various aspects of global sustainability. The researches in this special issue thus include, but not limited to:

  • Production and Application of Renewable Energy Resources 
  • Grid Integration of Renewables 
  • Role of Energy Storage Systems in Distributed Energy Systems 
  • Innovations in Power Electronics, Control Systems, and Algorithms 
  • Policy, Code and Regulatory Framework in the Sustainable Implementation of Renewables 
  • Amalgamation of Renewable Energy Sources in Net-Zero Buildings and Electric Transportations 
  • Study of Renewables in Environmental Sustainability

Hydrogen production using renewable power is becoming an essential pillar for future sustainable energy sector development worldwide. The Sultanate of Oman is presently integrating renewable power generations with a large share of solar photovoltaic (PV) systems. The possibility of using the solar potential of the Sultanate can increase energy security and contribute to the development of the sustainable energy sector not only for the country but also for the international community. This study presents the hydrogen production potential using solar resources available in the Sultanate. About 15 locations throughout the Sultanate are considered to assess the hydrogen production opportunity using a solar PV system. A rank of merit order of the locations for producing hydrogen is identified. It reveals that Thumrait and Marmul are the most suitable locations, whereas Sur is the least qualified. This study also assesses the economic feasibility of hydrogen production, which shows that the levelized cost of hydrogen (LCOH) in the most suitable site, Thumrait, is 6.31 USD/kg. The LCOH in the least convenient location, Sur, is 7.32 USD/kg. Finally, a sensitivity analysis is performed to reveal the most significant influential factor affecting the future’s green hydrogen production cost. The findings indicate that green hydrogen production using solar power in the Sultanate is promising, and the LCOH is consistent with other studies worldwide. Full article

The Industrial Internet of things (IIoT) helps several applications that require power control and low cost to achieve long life. The progress of IIoT communications, mainly based on cognitive radio (CR), has been guided to the robust network connectivity. The low power communication is achieved for IIoT sensors applying the Low Power Wide Area Network (LPWAN) with the Sigfox, NBIoT, and LoRaWAN technologies. This paper aims to review the various technologies and protocols for industrial IoT applications. A depth of assessment has been achieved by comparing various technologies considering the key terms such as frequency, data rate, power, coverage, mobility, costing, and QoS. This paper provides an assessment of 64 articles published on electricity control problems of IIoT between 2007 and 2020. That prepares a qualitative technique of answering the research questions (RQ): RQ1: “How cognitive radio engage with the industrial IoT?”, RQ2: “What are the Proposed architectures that Support Cognitive Radio LPWAN based IIOT?”, and RQ3: What key success factors need to comply for reliable CIIoT support in the industry?”. With the systematic literature assessment approach, the effects displayed on the cognitive radio in LPWAN can significantly revolute the commercial IIoT. Thus, researchers are more focused in this regard. The study suggests that the essential factors of design need to be considered to conquer the critical research gaps of the existing LPWAN cognitive-enabled IIoT. A cognitive low energy architecture is brought to ensure efficient and stable communications in a heterogeneous IIoT. It will protect the network layer from offering the customers an efficient platform to rent AI, and various LPWAN technology were explored and investigated. Full article

Renewable energy sources (RESs) such as wind and solar are frequently hit by fluctuations due to, for example, insufficient wind or sunshine. Energy storage technologies (ESTs) mitigate the problem by storing excess energy generated and then making it accessible on demand. While there are various EST studies, the literature remains isolated and dated. The comparison of the characteristics of ESTs and their potential applications is also short. This paper fills this gap. Using selected criteria, it identifies key ESTs and provides an updated review of the literature on ESTs and their application potential to the renewable energy sector. The critical review shows a high potential application for Li-ion batteries and most fit to mitigate the fluctuation of RESs in utility grid integration sector. However, for Li-ion batteries to be fully adopted in the RESs utility grid integration, their cost needs to be reduced. Full article
