Nuclear fission is most often categorized as dispatchable, though it's typically in with the slowest of that group when it is. Of anything out of this administration, a push for more fission power might be the thing I agree with the most as well though, so perhaps that's biasing my read.

Commercial nuclear fusion is just a dream at this point. We might as well debate whether my private island has enough room for an airplane runway or not instead. But hey, I'm not against continuing fusion research if that's all they mean.

EGS I'm far less familiar with but it'd be odd for the current admin to agree with the previous admin unless they had to https://www.energy.gov/sites/default/files/2022-09/EERE-ES-E... and it would, on the surface, make sense one could design these systems to support flow rate variability?

Grid scale batteries are power storage, not power sources. I do agree it's a damn shame they aren't brought up elsewhere in the report though. Same as anything else about renewables missing in tandem with that.
