Because stationary energy generation is the easiest thing to decarbonize, while other sources are much more difficult. Also some carbon sources are so disperse to practically track down. You going to hunt down every person using a diesel generator in Subsaharan Africa, go to their rural villages, and take their generator from them? Maybe, or it might be easier to just set up one big nuclear powered DACC plant. Then you don’t have to deal with the practical and political nightmare of hunting down millions of low intensity carbon sources among the poorest people on the planet. Just let the poor village keep its diesel generator til they’re ready to switch to solar. You don’t have to go in and start taking stuff from poor people. There are lots of examples of this, low intensity sources that add up in aggregate but would be a political nightmare to try and stop. DACC shines for this.
