* No paths to nighttime clean energy without nuclear power

  That’s the same thing

  You both just said the same thing.

    poster added provision Nighttime energy.

      I believe parent was making a point that the nighttime vs daytime distinction is irrelevant, because the grid never goes to to sleep. Having sufficient clean energy during daytime only is not acceptable.

  Why is that?

  Babcock and Wilcox have gotten out of the nuclear business. What business have they gotten into? Thermal storage of grid energy with a > 50% round trip efficiency. It heats sand with a compact resistive heater, stores the sand in insulated silos, and recovers the energy by a Brayton cycle system with a really interesting and compact fluidized bed heat exchanger. Storage capacity is sized for 100 hours of operation. Not just overnight, but four days. https://www.babcock.com/home/about/corporate/news/babcock-wilcox-nrel-sign-exclusive-ip-option-agreement-for-advanced-renewable-energy-storage https://www.babcock.com/home/about/corporate/news/babcock-wi... Westinghouse is also doing thermal grid storage now. Pumped TES can have a round trip efficiency > 60%. https://www.energy-storage.news/nuclear-power-company-westinghouse-to-build-2gwh-pumped-heat-storage-in-bulgaria/ https://www.energy-storage.news/nuclear-power-company-westin...
