That article is mostly fair.
I agree that new nuclear (including the small reactors) isn't realistic. There's a chance they become economic, but I'm skeptical. The important thing is the extend the life of existing nuclear as long as possible - at the very least until coal is completely phased out.
There is a substantial amount of pumped hydro on the energy storage side, but apparently there are very few good sites left, and it's an expensive technology. At least one of these alternative energy storage technologies will challenge Lithium Ion.
I strongly disagree that hydrogen won't have a role. It has some disadvantages compared to guess, even once it's economic, but it's the best chance to decarbonize aviation and, shipping, and industrial processes. Maybe biofuels will have a role, but even the most promising startups there are focused on waste-to-hydrogen.
Mechanical carbon capture probably won't really get much attention anytime soon, nor should it. Tree-planting, changing agricultural practices, and the like are more cost-effective, of course. Related to that, if the plant-based meat really takes off, then that could be a big deal since vegetables, fruits, and grains are much more efficient to produce than meat. I haven't converted to plant-based meat yet (I used to be more hopeful for lab-based meat but now I'm not so sure), but I'm hopeful that over time it will become more cost-effective and taste just as good. If that happens, the meat industry will be drastically reduced.
His plan doesn't specify using the military to deploy the emerging technologies, which was I great idea that Warren had. I suspect that the plan is still a work in progress, overall, so other ideas will emerge.
