Flexibility-Oriented Operation of Integrated Power and Gas Networks and Low-Carbon Technologies Under Clean Energy Transition provides a comprehensive examination of the critical role that integrated gas and electricity networks play in achieving a sustainable and low-carbon energy future. The book not only highlights the urgent need for flexibility in these interconnected systems, particularly through demand-side management and energy storage systems, but also addresses the pressing challenges posed by climate change and the transition away from fossil fuels. It offers insights into innovative low-carbon technologies, such as hydrogen and ammonia, while addressing the synthesis, storage, and transportation hurdles these renewable fuels face. The book's detailed contents cover essential topics, including the flexibility of coupled gas and electricity networks, operational strategies for achieving net-zero carbon emissions, and intelligent methods for assessing network adaptability. It provides a conceptual overview of decarbonization efforts for integrated energy systems and explores the feasibility of integrating artificial intelligence (AI) in these processes. Further, the book discusses the decoupling of emissions from economic growth, the role of negative emission technologies (NETs), and the application of innovative energy solutions such as gas carbon capture and storage (CCS) and hydrogen production. Case studies illustrate successful implementations of integrated networks worldwide, highlighting challenges and key lessons learned. Flexibility-Oriented Operation of Integrated Power and Gas Networks and Low-Carbon Technologies Under Clean Energy Transition serves as a vital resource for researchers in clean energy, decarbonization specialists, hydrogen production experts, energy utility companies, energy economists, electrical engineers, mechanical engineers, artificial intelligence developers, policymakers, energy service providers, and students in energy systems and is sure to be a welcomed resource.
