Abstract

Electricity-to-gas conversion is a key area of interest for decarbonizing and increasing the flexibility of energy systems, as it can both absorb renewable electricity during periods of excess supply and provide backup energy during periods of excess demand. By combining the power-to-gas conversion with the natural gas network, the inherent flexibility of the line package can be exploited and some of the power variability can be transferred to the gas network. Also, as long as the gas injected into the gas grid is low-carbon, such as hydrogen from renewables to gas, then the overall greenhouse gas emissions from the gas grid can be reduced.This paper presents the first review of energy-to-gas conversion, reviewing real projects, and system modeling studies and comparing them based on scope, assumptions, and results. The review identified significant interest and potential for energy-to-gas conversion in conjunction with the gas grid, however there are still challenges to be overcome to find profitable business cases and address local and system-wide technical challenges. Although significant power-to-gas modeling has been done, more is needed to fully understand the impact of power-to-gas conversion and gas supply to the network on the operational behavior of the gas network, taking into account dynamic and spatial effects.
