The cost of solar dropped by 90% between 2010 and 2020, and the cost of panels fell by 14% last year. Batteries were just straight up not a thing until 2019: California's grid-scale battery storage capacity has been doubling every year since then.
Putting together the solar panels, the battery, the desalination plant, and the brine plant, he's proposing a $42 billion dollar project that has only been economically feasible for a year or two now. I'm not surprised that it hasn't been built yet.
