We produce 700 cubic kilometers of hydrogen, but almost all of it is produced through steam reformation. No, we can't reuse the equipment that makes the hydrogen, we have to replace almost all of it with carbon neutral alternatives. And no, most of the infrastructure connecting these can't be reused either. Our existing hydrogen production facilities are set up to produce the hydrogen as it's needed for other industrial processes. Our existing hydrogen economy does not have a significant storage capacity. Rather, it's set up to minimize the need for hydrogen storage altogether. For your proposed renewable grid, we'd likely be transporting methane many miles away from its generation to under ground storage facilities. Sure, the existing pipes connecting to fertilizer plants can still be used. But we still need a lot more pipes connecting electrolysis plants, to storage sites, and to hydrogen to electricity production facilities. This isn't something our existing infrastructure is set up to support. Your proposal has us effectively rebuilding our hydrogen economy from the ground up: First, changing production from steam reformation to electrolysis. And second, building out a vast hydrogen storage and transportation network to deliver this hydrogen to where energy is needed. There's a lot more to your proposed hydrogen grid storage than just valves and pipes.
