The author actually talks about ESS in a comment to the linked blog post from the article. Apparently their battery generates a ton of H_2 that needs to be managed. That could easily be the sort of thing that only is possible/realistic at large scales, thus eliminating sizing the battery down indirectly. https://chemisting.com/2024/03/15/an-open-source-diy-flow-battery/ https://chemisting.com/2024/03/15/an-open-source-diy-flow-ba...
- kragen 2y agoyou can just vent h2 to the atmosphere
- jhayward 2y agoYour local fire department will want to very closely inspect your explosive materials handling and safety procedures. Think about what big banks of lead-acid batteries have to do, and google the pictures of battery rooms with their roof blown to bits.
- kragen 2y agoi'm familiar with the destructive power and unpredictable nature of hydrogen detonations, yes ;) but that's what happens when you don't vent the hydrogen to the atmosphere
- hlieberman 2y agoIt doesn't work so easily; if you do that, the battery itself will fall apart because of deposition of the iron. See: https://iopscience.iop.org/article/10.1149/1945-7111/abcf50/pdf https://iopscience.iop.org/article/10.1149/1945-7111/abcf50/...
- kragen 2y agothanks! so the rest of the thread here is sort of beside the point
- danielfp248 2y agoI am the author of the blog. The Zn/I chemistry actually generates very little H2, so that's not a problem in our current configuration.
