Canada’s alternative chemistry battery e-Zinc says it will do a pilot with Toyota Tsusho Canada (TTC) to validate its technology on a commercial scale. e-Zinc claims that it is suitable for really long-duration energy storage and this project is supposed to validate the e-Zinc ability to store energy for at least 24 hours, and as long as 3 days. Any commercial deal of any size right now for battery technologies which are immune from thermal runaway are of interest, but this deal seems to be a pilot, therefore it is not quite yet of significant commercial scale. Rethink has identified that alternative battery chemistries have a 3 to 4 year window to get into production, scale and drive down their…
