Humanity must quickly convert our global energy system from fossil to primarily renewable energy (RE) sources, to "run the world on renewables".But we cannot, and should not try to, accomplish this entirely with electricity transmission.The worlds richest renewable energy (RE) resources-of large geographic extent and high intensity-are stranded: far from end-users with inadequate or nonexistent gathering and transmission systems to deliver the energy.We will need more transmission and storage capacity than electricity can provide.Electricity energy storage cannot affordably firm large, intermittent renewables at annual scale, while gaseous hydrogen (GH2) and anhydrous ammonia (NH3) fuels can: GH2 in large solution-mined salt caverns, liquid NH3 in surface tanks.Thus, we need to now investigate and plan for a diversity of complementary RE transmission, storage, and supply integration media, fuels, systems, and strategies.We must embrace complete RE systems, from sources to firm, dispatchable, energy services.GH2 and NH3 are especially attractive;underground transmission pipelines for both have multi-GW capacity over hundreds of km.
