Why One Startup Is Building Solar in the Desert at Night
from The Climate Tech Podcast with Fexingo: Energy, Sustainability, and Decarbonization Companies · host Fexingo
Episode 28 of The Climate Tech Podcast explores a bold new approach to solar power: building arrays in the desert that operate at night using thermal storage. Lucas and Luna break down how startup HelioNight uses molten salt batteries to store daytime heat and generate electricity after dark, solving solar's biggest weakness — intermittency. They examine the technology, the economics, and what it means for grid reliability in places like Morocco and Arizona. With specific numbers on cost per kilowatt-hour and storage duration, this episode offers a concrete look at a niche that could reshape how we think about baseload renewable power. #HelioNight #SolarNight #ThermalStorage #MoltenSalt #BaseloadSolar #DesertSolar #RenewableEnergy #GridReliability #EnergyStorage #SolarEnergy #ClimateTech #Decarbonization #Business #Technology #Startup #Morocco #Arizona #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo
