Let's just hook up carriers and ice breakers to the grid. Or build a bigger plants on the decks of older carriers!Phanatic posted:Pretty sure you mean 'global carbon emissions from the power sector.' Heck Yes! Loam! posted:Its a crime that we aren't replacing these with nuclear. I had in mind some sort of UN Power agency that would just go around and replace old coal plants with standardized nuclear plants, free of charge for the recipient. Politically though it would be suicidal, I'm pretty sure, but I'd much rather go in that direction than deal with $5 carbon offsets on my flights and other nonsense.

mobby_6kl posted:New report just dropped (a week ago). Apparently 5% of power plants generate 75% of global (power generation) carbon emissions. They also probably generate a huge chunk of total electricity too since they're all huge coal plants, but still seems like pretty good news if we could replace them with renewables or nukes (lol). According to them this should be enough to cut total global emissions by 20% which seems absolutely massive. The article and report doesn't make it clear if these plants are excessively inefficient or just unusually large coal plants. The report talks about the intensity, but it's relative to other fossil fuel plants and coal plants probably are more intensive compared to oil and natural gas plants. But if the top-10 are just operating at the average coal plant efficiency, then it doesn't really matter whether you decommission one of them or 10 smaller coal plants, except for the people living nearby who have to deal with most of the non-CO2 emissions. Or it might be better to decommission smaller plants.It's probably more efficient to transport to coal to one huge plant than ten smaller ones. And if we some day come up with an effective CCS system, then these huge plants are the prime candidates for deploying it, as mentioned at the end of the article. If these huge plants are less efficient than average for some reason, maybe they have outdated boiler and generators, then they should be easier to upgrade than smaller. You can only renovate small portion of the plant while the rest keep operating, instead of shutting down the whole of smaller plant for a year.

It may be easier to solve the regulatory, NIMBY, project management, waste storage, grid tie etc for one big nuclear plant than for ten smaller ones. Ideally you could build nuke next to the existing coal plant and sell it as “we’re going to replace this dirty smog machine with this shiny new nuclear plant” and the locals would accept it, plus the grid infrastructure is already there as well as cooling water supply. Except for the issue of replacing perhaps 1000s of jobs with fewer higher skilled jobs.

Coal is a minuscule amount of jobs, they're just extremely loud, and in small states to boot. Either way, solar has a shitload of jobs that honestly need very little training, and even better, solar is needed all over the place so it's not geographically limited like mining jobs are. Nuclear doesn't need to also be a jobs program on top of everything else.

Yep there aren't many jobs all things considered but you can see the amount of stink the Poles raised over the Turow coal mine: https://eulawlive.com/insight-the-t...trajan-shipley/Saukkis posted:The article and report doesn't make it clear if these plants are excessively inefficient or just unusually large coal plants.

I’m in furious agreement with you but I’m cognisant of the resistance that will be pushed. Here in Australia there is constant talk about mining jobs being under threat from green programs, you would think that every second person was employed in mining. The reality is that mining is a small part of our employment figures and the majors have been throwing every dollar into automation, from extraction all the way through to loading the ships. Rio Tinto runs entire mining operations from control rooms in Perth with a handful of staff yet billionaires have been very successful in convincing communities that resource taxes will destroy their livelihoods.

It's really cool having entire industries that are actively harmful, but we can't shut them down because of the job loss, when it would be more productive than the status quo to pay them to do nothing for the rest of their lives. I understand it's not actually about the job loss, that's just convenient propaganda, but it gets done with everything from lead to asbestos to fossil fuels and voters and politicians don't see through it.

I was curious as to what Slovakia’s load is that 2 nuclear units coming online could cover 20%, and I was surprised to lean that those Mochovce units are 470MW each. That puts their load at only about 4500MW. I forget that some of those European countries are kinda tiny. And are not consuming on anything on par with the US.

He says it's just a ploy to keep getting natural gas subsidies. The process, when real capture efficiency and natural gas pipeline leaks are accounted for, is worse for GHG emissions than just burning the natl gas or coal. Eagerly awaiting natural gas flunkies insisting that it's merely a brief transition fuel, and that intentions are all good. .

813,319 acres is 1,270 square miles, or 0.8% of California's open space. A 1-mile wide stretch on both sides of the I-10, I-15, and I-40 highways would be an obviously massive undertaking, but it would be just about enough space, and if you've driven through there, there's nothing from horizon to horizon.

The problem remains that solar is not putting out its nameplate capacity. So double that amount if you want to actually reach that amount. And we don't have the storage to make it effective, and probably never will at this point. The nameplate rating for solar is only at its peak output, which it rarely reaches and only at midday.

and that's why we're adding "temporary" gas plants. In-state generation fluctuates but right now it's actually down compared to 10 years ago, and it turns out you can't always get power from neighboring states when they have a heatwave too. Unfortunately the general public thinks more solar is the answer and surely we can just grab a few Tesla batteries for storage, problem solved. Luckily we're pushing for increased electrification and BEVs while also losing Diablo Canyon in a few years, it should be great. I did the math a while back and I think conservatively if every mile driven in CA was a BEV rather than an ICE vehicle, California would need around 30% more GWh of generation. That was assuming all those miles were fairly efficient BEVs too and not trucks.

It brings inertial confinement designs to a similar technology readiness level to that of tokamak designs, but doesn't herald incipient commercialisation for either. It increases the odds of some form of fusion proving viable within the next thirty years by virtue of increasing the number of routes to it, but those odds were already quite low. Or, as I explained it to a friend who wanted a simpler version, shooty laser fusion now just as irrelevant as big magnet fusion.
