Overbuilding batteries isn't a great solution when the batteries in question only last 2-4 hours and are designed with summer loads and peaker gas plants in mind. They're great for what they do, but they're not going to replace power plants any more than your kettle is going to replace your hot water boiler.

If you had abundant nuclear power, you could get it from cracking seawater. If you have abundant renewables, you could use hydrogen to load-shift, cracking seawater into hydrogen when the wind blows and burning the hydrogen when the wind doesn't. But in no case is it a method of generating power.

WampaLord posted:So it sounds like either we overcome popular opposition and NIMBYism or climate change kills us all. If the only alternative to immediate massive construction of nuclear is for climate change to kill us all then climate change will kill us all because we're not currently building or planning on building any appreciable amount of nuclear in the near future. The perfect ideal scenario is for the government to nationalize the energy sector and start building all the nuclear. Also they should give us UHC, UBI, free college and massively build out public housing and transportation. The government should do many things that it is not going to do unless the political landscape dramatically changes. Currently it looks like we will have very modest growth in nuclear and a lot more additions of wind and solar. Wind/solar costs have not plateaued yet and may not do so for some years. Green hydrogen plays into this since we will need to produce it for industry, shipping, planes and for heating in some places. Australia have quite large projects in the works but there's projects in Europe as well. That's the trajectory we're on. It's not ideal and we most likely can't get to zero emissions. Maybe the political landscape will change some time in the future and we can get more nuclear additions but that's not where we are now.

Yeah ok that French site lets you download the actual hourly data for the past year (though 2021 is 404 ) so I had to gently caress around with it of course. If they went full Germany and shut down the nukes, it seems that they'd need to increase the solar installed capacity by 5x and wind by 11x to average a monthly surplus. Then to make sure you never actually run out... 30,000,000 mWh of storage capacity. It's getting very late so I might've hosed something up, but seems like a lot! Obviously there could be different optimal permutations depending on what's most cost effective etc., and this allows no imports as well.

You've got an excellent point that renewables are backed by fossils, but if progress is moving from 80% yearly generation coming from coal, to 70% coming from renewables and 30% from gas, well I'll take it. Current trajectory is something like over 80% renewables by 2030, so we won't have long to see if it's achievable. Gas sure as hell isn't good or clean, but we're still burning brown coal ffs, which is only one step above wet newspapers.

Nickel Iron batteries have lower energy density than Lithium, but since you don't really care about weight for terrestrial applications, some people use them for "power walls." They are extremely durable. 50 years easily. And they are simple, Edison actually invented them. The smaller market makes them a bit more pricey than the materials would warrant.

When it comes to the economics of energy production, I think you need to consider, for whom is it economical? The producer or the consumer? Wind in particular here in europe is cheap now to build and install and with the power crisis stemming from german choices and now the war in ukraine, it's really economical in terms of getting a fast return on investment. It's not so economical fore the consumers however because of intermittancy issues leading to lack of energy and thus record high electricity prices on average, while it can also have real lows. Until the fantasy tech of cheap large capacity storage is ready that's how it will be. Nuclear is the opposite, it's a lot less attractive for investors because it's a lot of money that will take a long time to yield returns, but it produces cheap power and reliably so, lowering the price on the market. This is good for the consumer, but bad for the producer. OL3s test output and promise of generation lowered market prices noticeably in finland this spring, and when it was delayed to december, prices raised another 30% and experts say that's how it will be until OL3 comes online. Historically in Sweden when they had all their reactors online they had an extremely environmentally friendly energy production in the form of nuclear and hydro, during this era they had some really cheap electricity, almost too cheap to meter one might say. Since then they have spent a lot of time moving away from this model, also deregulating heavily in the 90s, now they reap the rewards and the government did stuff like hand out emergency money last winter to help people pay their heating bills. I suppose one might also consider what's "economical" for the planet? I remember reading studies recently that wind and solar require more resources per kWh produced than nuclear, so producing power via wind and solar will require more raw materials than nuclear power. It's clear to me a huge part of tghe probvlems we face are because of trhe private sectors involvement in energy production and the marketization of electricity which skews incentives towards more expensive electricity. The free market producing lower prices is of course a fairy tale.

Oh hey; Silence_Kit, I see you dragged out Lazard to push your agenda that nuclear is expensive but you didn't get around to telling me why my below quick assessment analysis was wrong. e) link for convenience https://www.lazard.com/media/451881/lazards-levelized-cost-of-energy-version-150-vf.pdf Electric Wrigglies posted:Great link. The batteries with solar is less about load shifting and more about handling short term dips due to clouds from what I understand. Yes you can load shift on a great sunny day but to deliver speced power it is cheaper to only build so many cells (say 10 MW) and cover output dips with batteries (a few MWhr) then to overbuild the solar plant (say 30 MW, no battery) to guarantee speced power (the 10MW as for the solar and battery) no matter the cloud intermittency. E) and to add, the reason that they do this (as opposed to just building the 10 MW no battery) is that grid operators are now getting snaky on renewables just lumping unconditioned and unpredictable power onto the grid and writing more certainty into connection conditions.

This thread has trashed Ivanpah and solar thermal in recent history. It has a habit of discussing dead/dying technologies over the more relevant ones. I think this message simply ignores most of my points out of hand but anyway. ok you restate that nuclear is expensive when your own link demonstrated that it is in line with non-dispatchable power when out of peak generating periods before considering the cost of storage to make non-dispatchable useful for anything other than cutting the lunch of dispatchable power generators and cheaper than scalable dispatchable renewable (solar thermal) before it too goes through NIMBY resistance acceleration that seems to accompany any form of energy / heavy industry growth. This is before you get into the persistent and insistent resistance to nuclear pushing up all the costs. It is not going to halve the cost or anything like that but nuclear does not need to be cheaper - that's not the real issue, the issue is scaling and that is predominately limited by green movement promoted NIMBY at the current stage but would become technical (foundries, staff, inspectors) if NIMBY did not exist. That scale limitation is why hydro, wind, especially load matched solar (hot weather linked air con market) and others all should be part of the mix. If nuclear generation had a deterministic and predictable pathway to permitting, you bet your bottom dollar there would be investment. Some of the tollways don't have paybacks for 20 years on 10's of billions of dollars of investment. BHP tipped 7 billion into an underground shaft not scheduled to haul a rock for five years (gambling on long term potash prices and other producers coming to market). Investors do like long term investments. They don't like ones that have greenpeace ramraiding your facility and starting riots in 10s of cities over.

I think there is a fundamental disagreement on premises that is fueling a lot of the argument in this thread. If you believe we're going to break from historical patterns and spend whatever is necessary to reduce carbon in time to limit global warming then building more nuclear plants looks like a great option because its a proven way to provide baseload power without emissions. If you believe we're going to continue historical patterns instead, constructing additional nuclear plants looks like a terrible option. This is because new nuclear plants will take money from a limited government "renewable power" bucket that would otherwise go to a mix of transmission network, demand management, and storage projects that will reduce the required amount of fossil fuel generation more than the same amount of money spent on new nuclear plants would. Wind and PV solar are now so cheap that their buildout is going to continue regardless of what governments decide to do, but if there is no mechanism for that wind/solar power to get to consumers it is going to instead be used for less useful stuff like very inefficiently creating hydrogen or mining crypto.

That's not necessarily true, since nearly all governments do not fund Nuclear as Renewables, so the funding doesn't tend to come from the same budgetary bucket. Biden's nuclear bailout being a good example Another reason this is false is that renewables are not scaling at the same rate demand is increasing, the idea that we can only do one or the other is insane. We can easily do both renewables and nuclear. And for the energy density: No, renewables CANNOT match nuclear for both footprint, output, and capacity factor. There's very little that can even among fossil energy systems. But again, the idea that its one or the other is shortsighted. Nuclear also is one of the few that can match its nameplate capacity daily. Combined with Renewables, Nuclear could easily offset fossil usage if built out. slorb posted:Wind and PV solar are now so cheap that their buildout is going to continue regardless of what governments decide to do, but if there is no mechanism for that wind/solar power to get to consumers it is going to instead be used for less useful stuff like very inefficiently creating hydrogen or mining crypto. Cheapness =/= good. Why is it everyone thinks cheap is somehow a saving grace? Where do we get this idea that we're going to offset subsidized fossil fuels with cheap renewables that cannot match the capacity factor of the fossil fuels you intend to target with them? We are not solving climate change on the cheap, and despite being cheap the amount required to offset the energy you are targeting for replacing is immense. And dont get me started on longevity, both wind and solar have ~10 year lifespans at best and tend to require frequent replacement.

This is obvious and I cannot understand your eagerness to handwave it away. Most of the "new" carbon dioxide emissions are coming from places like China and India. If the best solution you have there is that Indians pay something like ten times the upfront cost of a coal power plant for equivalent Mwh, it's much less likely to get done. If the private sector starts seeing positive NPVs for nuclear investments (like they already do for solar, in some applications) they'll start doing the work for you. So yeah, get costs down and the job gets a hell of a lot easier!

I agree to some of CommieGIR that both can be done at the same time (and still get frustrated at the fixation on cheapness being wrong when wholistic grid lowest cost (inclusive of externalities) is absolutely the KPI to focus on) and I think you are onto a big reason of pushback on nuclear. Anti-nuclear sites themselves state as one of the reason why nuclear is not viable is because it will canibilise funding for their chosen pathway. Whether that is because they think along what your describe and strictly believe every dollar spent on nuclear is that much more carbon in the air or whether that is because like a lot of coal workers, anything that might take yer jerbs is anathema. In any event, historical patterns can be changed, the world went pro-nuclear to anti-nuclear in a generation. Germany may be going back to wholy hydrocarbon and renewable mix but Japan, France Finland, UK, China, India, S. Korea are all heading towards nuclear and renewables (and umming about the last bit so that stays carbon). And on the wind and PV so cheap, I believe a big part of their cheapness is because curtailment has not yet really been costed into their profiles. PV matching up with A/C load is great and really is cheap (not as cheap as solar hot water but is definitely hard to go past) but I would love to see a set load (say 100 MW) of overnight heating without carbon levelised cost of generation chart. If I understand right, It's 33 x 3 MW wind mills on a good night with carbon/nuclear back up but 264 windmills (8% wind) is 277 windmills (95% Avail) is 347 windmills ( 20% surplus that is evidently required) if it >99% confidence interval has to deliver without backstop. Straight away that 3 c a kwhr for wind when it gets to sell every kw is now 30 c a kwhr (33 windmill market / 347 total windmills required to meet that market reliably) due to curtailment. This is where batteries are meant to do fusion for renewables but what is the cost for batteries per /kwhr? Electric Wrigglies fucked around with this message at 16:25 on Jul 22, 2022 |

Agronox posted:Because in the real world, resource constraints matter? This is obvious and I cannot understand your eagerness to handwave it away. You're mistaking "internalized cost" for "resource constraints". Coal power is real god drat expensive when you consider the external costs, considerably more than nuclear power I'd wager. It's cheap to get a coal plant built, you pay the remaining costs and "costs" years later

Rampant climate change is the cost of gas and coal, but weirdly lobbyists owned by those industries don't include that in their graphs
