But that aside, just looking at the sheer magnitude of capacity mentioned in his papers, one can see that it's not even remotely easy or trivial. See eye-watering Table 2 in [2]

Do you bet against this?
I'm pro anything low carbon. I love wind and solar and hydro and nuclear. These no-nuclear people are trying to get us to tie a hand behind our backs for no reason in the midst of a climate crisis. Energy generation choices are not a zero sum game.
Lots of antinuclear people mistakenly believe that pro-nuclear people are also anti-wind or anti-solar when in fact we are usually just anti-fossil and biofuel.
So you are telling me that a peaking nuclear plant will solve the last 10% when it comes online at earliest 2040? What problem are we even solving then rather than brute forcing nuclear into the solution?
Then try put that nuclear power plant on a marginal price market. What do you expect to happen?
The research finds it easily solvable today, but a holistic approach is necessary.
