Abstract: The European energy system is undergoing a major transition to reduce carbon emissions, aiming to become fully carbon neutral by 2050. This transition is characterized by an increase in renewable energy-based capacity, such as wind and solar, in the electricity sector. Integrating this variable renewable energy into the overall energy system could be facilitated by sector coupling. Three energy transformation processes are the bedrock of sector coupling: power-to-heat, power-to-liquids, and power-to-gas. In this chapter, we provide an overview of Power-to-Gas systems (P2G). We focus on P2G because this concept can potentially facilitate the decarbonization of the gas network. An overview of the state-of-the-art shows that the role of sector coupling and P2G in future energy systems remains to be seen, particularly if an energy system integration approach that prioritizes energy efficiency and cost-efficient electrification is applied. All in all, a cost-efficient implementation of sectoral coupling concept would require the technical feasibility and economic profitability of P2X concepts, as well as a coordinated planning and operation of all elements of the energy system involving generation, transmission, distribution, and consumption across all energy sectors.
