Firebrick systems powered by renewable energy could be used for up to 90% of industrial process heat applications, the Stanford study says. Meeting that demand in the U.S. would require firebrick system capacity of 2.6 TWh, with a peak discharge rate of 170 GW.
Their previous study also goes into efficiency and cost.
One of the main advantages of firebricks is their low cost.
Ok, they’re claiming 98% rt efficiency.
I don’t think we have 98% rt efficiency in anything, ever. That’s miraculous. Batteries are around 92% at best? Pumped hydro is 85% or so.
That even sounds high for raw carnot efficiency.
I mean, if so, wow, that’s awesome, and I don’t really doubt their 1% daily decay, that seems attainable.
But 98% rt? I’m still skeptical.
