Not sure I follow here. Can you elaborate?
Are you saying the the demand for sodium batteries for power grid backup is going to be high vs supply such that they're not going to make it into cars anytime soon? Isn't one of the Chinese EV makers starting to use sodium batteries?
- alemanek 3y agoYeah I am thinking grid applications will take up most of the available supply for the next few years. That charge/discharge speed makes it perfect for helping to stabilize the grid, frequency regulation, as well as for replacing peaker plants. Lithium batteries are already being used for these two applications but I think these sodium batteries would be better.
- jacob019 3y agoDepends on the production economics, how fast they scale, and what issues are discovered in real world use. There is some risk for everyone with new tech.
- xbmcuser 3y agoLarge scale grid project are planned years in advance so unlikely to eat up all the production as factories will need a constant demand source to clear inventory and have regular cash flow so I think home batteries like Tesla powerwall are going to have big boom soon specially as people getting paid less and less for their home solar output from the grid. If I am not wrong chinese largest battery manufacturers have started looking at home batteries as some car manufacturers were complaining about not enough demand for ev.
