| I think you are obsessed with ammonia as a fuel source. Ammonia might never make it to peaker plants, nor farm, nor construction equipment. The sun shines brightly 100% of the time and the wind blows strongly 100% of the time... somewhere. California currently imports electricity from... Wyoming. With a network of ultra-high-voltage electricity transmission (UHV electricity transmission) lines https://en.wikipedia.org/wiki/Ultra-high-voltage_electricity... throughout the USA, the current concern many engineers seem to have with "the energy storage problem" associated with renewable energy might vanish into irrelevancy. At 7pm on Tuesday, most of the East Coast might get 80% of its electricity produced by photovoltaics in the Mojave Desert in Nevada; whereas on Wednesday at 2am, Florida might get 90% of its electricity produced from wind generators in Custer County in Oklahoma. Even if 20% of the electricity were lost due to long-distance transmission, it wouldn't matter much if the electricity were produced extremely inexpensively. Currently, almost 100% of the aforementioned solar and wind energy are "lost" because almost all of the sunlight in the desert simply lands on the ground, and the wind in the prairies simply blows along without being utilized. Sure, for airplanes and cargo ships, fuel is important. But for most terrestrial uses (such as in cities and farms) "just in time" electricity might be the best solution. "But, what about outages?" I'm glad you asked. The military and hospitals have backup diesel generators. Personally, I think "evil" coal-fired power plants might be a feasible source of local, backup electricity which would normally be used very rarely. The current "anti-coal" bandwagon is absurd. Coal is a great source of fuel. However, much of the world "went crazy" burning way, way, way too much coal for a couple of hundred years. We never should have done that because of the terrible pollution we suffered from. My favorite things about coal are this: it's very easy to store and very easy to burn. If people want to store tanks of hydrogen gas in their backyards above ground, or tanks of ammonia underground, that would probably be fine too. But for large scale, backup sources of electricity (say for a city like Portland, Oregon) "evil" coal-fired power plants might be the cheapest and easiest method. As long as the ultra-high-voltage electricity transmission network has suitable redundancy, is maintained properly, and is not sabotaged (say, by terrorists) then I would guess that within 10 years or so, it would be up over 95% of the time; and within 25 years or so, it would be up over 99% of the time. |
Coal plants are monstrous beasts that need a long time to fire up and a lot of expensive maintenance whenever down. Combined-cycle turbines start up in a few minutes, are cheap to maintain, and a little one makes as much economic sense as a big one. But storing LNG, long-term, is a nuisance. So you want to fire them on something readily stored, liquid unless you have a salt dome. So, ammonia, or synthetic methanol, metal hydride, or even mined and refined kerosene. Because it is just for emergencies anyway.
