Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Why do you assume that all backup capacity for a given grid must be provided by fueled power?

Also, how common natural gas peakers are is determined by how useful they are in a fueled power system, in which we imagine that the average minimum amount of power required over a day are special "baseload" electrons, which have to be provided for separately from "following load" electrons and "peak load" electrons. Some similar peaker plant, say ammonia peakers, could be as common as a complement to the balance as they are required to be.

Indeed, if it takes time to build up an appropriate capacity of Direct Carbon Fuel Cell for the more efficient use of biocoal, then since baseload power plants would be driven out of business by a 40:20 mix of wind and solar, we would have ample opportunity to pick the most useful of the shut down coal power plants to use for biocoal power production in the event of a shortfall of solar/wind. After all, about half of a given shortfall will be predictable a day or more in advance.

And this concern with issues of dispatchable sustainable renewable power to complement the volatile harvested renewable power seems to be difficult to understand in the context, since you answered my comment which was a a response to melo's question about why solar panels are so often installed without tracking units. I don't see the connection between how sustainable renewable dispatchable power sources and storage fits into the issue of whether or not solar panels have tracking.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
