Integration Opportunities of Power-to-Gas and Internet-of-Things Technical Advancements: A Systematic Literature Review

Abstract

As renewable electricity integration generates grid-balancing challenges for network operators, new ways of grid resilience receive significant attention from the energy research community. Power-to-gas (P2G) applications could produce and use green hydrogen. Thus, they enable the integration of more renewable energy into the energy system. Meanwhile, Internet-of-things (IoT) solutions could optimize renewable energy applications in decentralized systems. Despite the strategic importance of both technologies in renewable-rich grid developments, opportunities for P2G advancements based on IoT and related solutions have not come to the forefront of renewable energy research. To fill in this research gap, this study presents a hybrid (thematic and critical) systematic literature review to explore how strategic co-specialization opportunities appear in recent publications. Findings suggest that P2G and IoT could be fundamentally linked within the proposed frameworks of multi-energy systems and energy internet, but further empirical research is needed regarding their operative and strategic integration (e.g., cost reduction, risk management and policy incentives).

Innovation green technology in the age of cybersecurity: Balancing sustainability goals with security concerns

“…The integration of green technologies into existing systems presents both challenges and opportunities. The discussions by Almalki et al (2021), Mehanneche andZemmouchi-Ghomari (2022), andMagyari, Hegedűs, andSinóros-Szabó (2022) highlight the need for innovative solutions to overcome integration challenges. As the world moves towards a more sustainable future, the role of green technologies in smart cities, supply chain management, and renewable energy systems will become increasingly vital.…”

Innovations in Battery Technology: Enabling the Revolution in Electric Vehicles and Energy Storage

“…Continued research and development efforts aim to overcome current challenges and bring solid-state batteries closer to commercial viability. Principles and Working Mechanisms: Solid-state batteries operate on similar principles to conventional lithium-ion batteries but employ a solid electrolyte instead of a liquid or gel electrolyte [63]. The components typically include Solid Electrolyte: The solid electrolyte, often made of ceramic or polymer materials, allows the conduction of lithium ions between the battery's positive and negative electrodes (cathode and anode) during charge and discharge cycles [64].…”
