We we're dicussing grid energy storage, now you mention the fuels problem. sure that's a bigger/different problem.
>> Super-abundant salts, or organic compounds, might work. But you're still left with scale-of-operation.
Please explain ? Assuming we have all the materials at a cheap enough costs - we just need to build , no?
- dredmorbius 11y agoBattery (redox) storage is sufficiently low-density that you're starting to talk about significant land area simply dedicated to energy storage (same applies to most other options -- again, thermal salt energy storage is among the denser options availabe). Keep in mind that that's not only large areas, probably poorly co-locatable with other uses (liquid / molten salt batteries at 600F and residential areas don't mix well given accident risk -- the substrates are relatively safe, but anything in volume at 600F is a hazard), but they're hugely technical large land areas. That's already a challenge for virtually all solar energy options. Factor in likley 10-20 year lifecycle, and you're talking about large land areas with 5-10% annual replacement requirements -- a lot of O&M expense and reinvestment.
