I thought the prospects for flow batteries were becoming fairly dire due to the decline in cost of Li-ion cells.
LFP promises better fire behavior than older Li-ion technologies, I think.
- jaggederest 1y agoI suspect for extremely large batteries or seasonal shifting (summer->winter) flow batteries will still have a place, but I could be wrong.
- pfdietz 1y agoFlow batteries aren't any good for seasonal shifting; the capex per kWh-capacity is much too high. Granted, ordinary batteries aren't good for that either.
- skybrian 1y agoThermal batteries make more sense for that, but they need to be super-cheap. One possibility: https://austinvernon.site/blog/standardthermal.html https://austinvernon.site/blog/standardthermal.html
