That's not my issue. My issue is that we currently have working nuclear technology. That we can build and deploy now. Bullish means we're relying on future inventions. With the potential catastrophe we have ahead of us I don't think it is a good idea to put all our eggs in one basket. It may not pan out. It may not pan out in the timeframe we need it to. Nuclear is a relatively cheap risk reduction strategy. Be bullish on battery, but have a backup because in the mean time we're still using coal/oil/gas.
I dont doubt that we can build nuclear plants. But right now the number of nations that can actually pull it off is small. Changing that would require new tech, modularisation, mass production etc. That is great and we should do that. But will it happen quickly?
I think there are good reasons to be bullish about battery storage. It is already an area of massive research. It is something we need to scale anyway due to electric cars. And it is very easy to deploy to the existing grid. You just need a concrete pad, some power gear, and a substation.
Being optimistic about nuclear does not mean we cannot be optimistic about batter storage.
