Sector coupling and renewable energy integration for the defossilisation of the economy : status quo and perspectives

Abstract

This Master’s Thesis examines sector coupling as a means to defossilise the secondary economic sector for the energy transition of the economy as a whole. It includes the heating and cooling, gas and electricity sectors and assesses their defossilisation potentials. The research investigates the different existing technologies and P2X pathways for sector coupling. It includes direct and indirect electrification, as well assources of renewable energies and renewable energy conversion solutions like hydrogen based technologies. It finds that sector coupling holds particular potential for the defossilisation of the heating and cooling industry. Historically, it examines the origins of each of the energy vectors and draws conclusions regarding their potential of systems integration. The hydrogen vector, in particular holds potential but lacks infrastructure and technological development, inter alia, regarding storage solutions. Thus, electrification is emphasised in the course of this work. Geographically, it focuses on coupling strategies within greater Europe, and compares it with the status quo of other internationally relevant energy systems where applicable. New concepts are emphasised like the holistic LINK-based paradigm for smart grids as well as other smart solutions. By systemically reviewing literature, analysing policy implications, and addressing technological challenges, this research aims to provide valuable insights that can drive the adoption and implementation of sector coupling strategies, ultimately contributing to the understanding and implementation of integrated energy solutions.
