Looks to be about 1,000 new coal plants being built or at least planned. Most of which are in China. Which will no doubt operate for decades.
Obviously North America is more interested in Solar, Wind, and Natural Gas. Eventually we will get to gridscale power storage. Suddenly it'll be problem solved.
Nuclear isn't difficult to build because of environmentalists, it's difficult to build because we don't know how to build big things anymore.
Check out the autopsy of VC Summer's failure, or the delays at Vogtle, and you won't find any environmentalists to blame. At least I haven't been able to find any hint of that, and if it were possible to blame environmentalists, I would think that the contractor and utility would be screaming it.
We have already kickstarted positive feedback loops like thawing of the tundra, reduced albedo due to smaller ice sheets, ... . We actually need to go carbon negative for a while to offset those. The technology you mention surely will help greatly in avoiding speeding things up, but they won't take us back to preindustrial levels alone.
California's last nuclear plant is almost done. Environmentalists are against nuclear and so it's difficult to build more.
In all the world, I believe only about 100 nuclear plants are even planned. Most of which are in China.
