Firebrick heat storage technology, not batteries, will be used to store energy for industrial process heat in a 100% renewable energy system, says a study out of Stanford University.

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.

    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.
