Superb analogy indeed as this is the same approach I use in my next pursuit in breaking through to those from a technology background. The cache sources can be anything providing energy to be stored in the rapid response system while the cache system itself is modular in design allowing ingress and egress simultaneously based on inputs and outputs of demand. The fun part is designing and writing the software to control all the "cache" hardware. I have no idea what I am talking about though but I did stay in a Holiday Inn last night... or was it a Motel 6. :) For those with their ear on the track when that sound resonates they will see the light, everyone else will be in the dark without energy storage. Costs are spiking everywhere and the U.S. government is having meetings near weekly exactly about this coming fun. Those meetings reflect frank direct statements about coming derailments and the grid has not changed since its inception and remains to be centralized to this very day. There are enough smart technologists here that can put together exactly what I infer, significant opportunity. For those further interested check out YT: "Environment Hearing: Clean Power Plan 2.0 Will Jeopardize Reliable and Affordable Energy". As with anything making significant revenues however those threatened with revenue loss will play the dirtiest games to preserve their position, this includes increasing the pollution output that is making that revenue. Stay Healthy!
