Since it's relatively low pressure (5% of a hydrogen fuel cell), couldn't they have larger batteries for grids? The current size would be great for homes.

- pjc50 3y agoThat looks suspiciously similar to a standard gas tank size. Generally you make a battery by combining cells - they have a 1-1.5V terminal voltage. The image lower down shows a rack of them in a warehouse. I suspect you'd stack them up to a few hundred volts and plug them into an inverter. I wonder if they require the same balancing as more delicate chemistries.
- aidenn0 3y agoEnerVenue's website has some claims that imply (but do not state, and remember this is marketing material!) it is much less delicate: 1. No thermal runaway and "phenomenal overcharge, discharge and deep-cycle performance" 2. "Flexible charge and discharge rates" 3. "Vessels can discharge to 100%" 4. Specified charging rate of C/12-C/2 (i.e. can be charged at rates from 1/12 the capacity per hour to 1/2 the capacity per hour) They do require usage of a tiered BMS though: https://enervenue.wpenginepowered.com/wp-content/uploads/2023/04/Enervenue_BMS_Datasheet.pdf https://enervenue.wpenginepowered.com/wp-content/uploads/202...
