What Happened Next by tserong, 4 December 2025:
A flow battery is, fundamentally, a machine. It has moving parts, and it potentially requires maintenance. Readers will have realised by now that I am quite mad rather obsessed somewhat of an enthusiast and don’t mind having to tinker with things occasionally. I imagine this is not the case for most people, who likely want their energy systems to Just WorkTM and require no special attention.
A viable flow battery, especially for residential usage, thus needs to be as low-maintenance as possible, and as easy to work on as possible when it does require maintenance. That latter point is a function of both unit design, and choice of installation site. The crawl space under our house for example is ideal if a battery only requires infrequent maintenance and minimal disassembly. If the whole unit needed to be stripped it would be much better off in a shed or other room that has appropriate access. Finally, these things need to come with a complete service manual including descriptions of all the parts and every possible procedure that might need to be performed in case of failure.
