Nope, you're stuffed for the busses as they are going EV too...
BTW, the trend is cobalt free for batteries. Tesla batteries in China are already cobalt free but they have less power. There is a Tesla battery day presentation some time tonight where Musk will reveal their latest work on more power for less weight with less cobalt and other stuff.
But, yes, I'm highly critical about people who say we can just use Wind and it will all be OK. ALL we have to do is rely on everyone else.....
Me? Nuclear 30%-40% until we sort it all out. We have had 1 week becalmed before. 1 Week of the UK grid is astronomical in terms of power storage. I worked it out in terms of Lithium Ion batteries one time. It's tens of trillions of £ at current costs.
There are, however, such things as flow batteries. There is the Swedish work on an enzyme which absorbs energy from the sun and can release it up to 10 years later with about 70% power retained. It is fluid and needs a catalyst. Early days but worth watching for grid power balancing.
The whole thing is that it is impossibly early in the whole process but we need to be 50 years ahead of where we are today. The problem with that is that 50 years ago everyone was saying "what CO2? Shut up it's rubbish".
We are 50 years behind and every year we don't deal with the problem we fall 2 or more years additional behind. When we reach 100 years behind people will already have started to die. But, by then, it will be too late for billions of our fellow umans.
