Special Focus on Gas Infrastructure--Part of World Energy Outlook 2019

Questions about the relative importance, and respective roles, of electricity and gas networks are central to the design of energy transitions. Low-carbon electricity has huge potential to play a greater direct role in future energy systems, but there are limits to how quickly and extensively electrification can occur. Well-established gas grids can deliver twice as much energy as electricity grids today and they are a major source of flexibility.
