“I think we're going to end up with sort of three tranches of storage in the grid, which are going to be filled by at least three different technology categories. The first is those short duration, you know, peak of the peak applications that lithium ion is, is addressing today. And I think probably lithium ion or some cousin of lithium ion, maybe like sodium ion moving down the road is going to be addressing indefinitely. And then you've got this middle tranche, which is diurnal cycling, which I happen to think heat storage is a really good solution for. But there's probably the most novel, most number, the highest number of novel approaches to storage that, that fall into this sort of middle duration category, which is, I think, 12 to 16 hours is a good benchmark for it.”

Lubbershane: New gas plants are the only near-term option for gigawatt loads
“I mean, if you do need to serve gigawatt scale new loads within, like, let's say the next three, maybe even up to five years, it's really hard to find, to think of another option that will really work, especially if that's, you know, more than very low capacit…”
Lubershane: Retail electricity prices will outpace inflation, driving broader inflation

Lubershain: The nuclear industry cannot sustain a Cambrian explosion of reactor designs
“There just can't be a Cambrian explosion of new reactors. The, Industrial logic of the nuclear industry just doesn't lend itself to that. I think best case scenario, it's bad for the industry if you end up with, you know, four or five competing reactor designs…”
Lubershain: Geothermal deployment will not truly take off until the 2030s
“I think that the inflection is, is going to be much slower and happen over the next five years, and that geothermal will really be positioned to take off more so in the 20 thirties than in the late 20 twenties.
That's my bet at the moment.”
