The Impact of Cobalt Free Batteries on the Grid

I'm not sure that the impact on the grid is as big as people think it is. Even if you running electric cars on a fossil fuel powered grid, you're still coming out ahead on carpon omissions. There's a huge amount of energy going in to trying to make cobalt free batteries and new battery technologies. Another way forward is as a bunch of start ups looking at maybe we can find the rare elements we need for batteries on sea bed. We've seen this before with nuclear power - there was a shortage of uranium then they found a whole load of it in australia.
