Cool Batteries Don’t Burn Viridi Parente’s CEO Jon Williams
from Sean White‘s Solar and Energy Storage Podcast · host whitehousesolar
When a battery cell heats up a lot, it can propagate to its neighboring cell and usually they do propagate on the cell level and not the battery storage unit level, but Viridi Parente has figured out how to not have cell propagation and has gone through the UL 9540A fire testing to prove it. They are working on a residential battery that will be “listed and labeled for use in habitable spaces” which nobody has ever successfully done to the best of my knowledge. This means that you would not have to follow the 2024 International Residential Code (2021 IRC with different wording), which means they can put as much as they want in any room in a house, once this is a done deal, which will probably happen in the first quarter of 2026. Here it is in the IRC: https://up.codes/viewer/mississippi/irc-2024/chapter/3/building-planning#R330.1 This is big news that could revolutionize energy storage. Viridi Parente has two factories in historical places. The Ford Motor building in Richmond CA where Rosie the Riveter worked and was photographed during WW2 and also the other factory in Buffalo NY was a GM factory built in 1920 which was also building tanks for WW2, so besides kicking Nazi’s butts, these buildings will help with the modernization of the grid. Jon and Sean also talk about virtual power plants (VPPs) and the internet of things (IoT). They cover how using energy storage can lead to a lot less current on wires and how you can run 40 houses on a single 200A service with the right amount of energy storage and coordination.
