Historically, the interaction between the gas and electricity networks has been one directional: the electricity network has been one of the consumers of the natural gas network for running gas power plants (i.e., gas to power, GtP). With the increased penetration of renewable energies into the electricity grid, a new challenge of electron oversupply and undersupply arises due to variable renewable resource availability. This challenge has created abundant interest in the “power-to-gas (PtG)" concept, where surplus electrons from the electricity network can be utilized for hydrogen or methane production to feed into the natural gas network. In this chapter, we investigate the PtG and GtP concepts and analyze the challenges and opportunities of available options.
