The significance of gas for the resilience of future energy systems

Abstract

This paper discusses the applicability of the resilience index with the aid of an exemplary energy system which integrates the gas, heat and power sector. The resilience index is a potential way to quantify the resilience of a considered energy system. It is an additional criterion to assess a system such as sustainability (in terms of CO2 emissions, for example) or economic efficiency (in terms of operating and / or investment costs). It is expected that hybrid systems, like gas condensing boilers with an integrated electric heat pump, will improve the resilience of integrated energy systems. Also, energy hubs with connectors to different energies will improve the flexibility and the resilience of energy systems. Integrated energy network planning tools are necessary to develop new, locally adapted energy system architectures.
