Not directly related to the article, but I wonder if the renewables industry being so hostile to nuclear is actually because renewables don't make sense with nuclear.

We started off with 100% of power generation being either fossil fuels or nuclear (+hydro etc. but these are minor for most places). As part-time renewables enter the stage, they take priority over the fossil fuel plants when they do produce, and simply go quiet when the wind don't blow and the sun don't shine. We accept that, because we're fundamentally still in a fossil fuel energy mindset.

So what does the post-fossil fuel world look like, with a nuclear+renewables mix? Well, we have as much renewables as we'd like, but really (and here's the kicker) we also need enough nuclear for windless nights (or winter days which in e.g. Northern Europe barely count as daytime). So really, we need to be able to power nearly 100% of the economy through nuclear alone in those cases.

But then, that begs the question, do we still need the renewables at all? Right now it probably makes sense, because it lets you throttle back the fossil fuel burning, so is a net win. But if your baseload generation is carbon-free (at the margin anyway), it doesn't matter. You just don't need the renewables.

This is somewhat oversimplified, perhaps. E.g. the times when you are less likely to have wind and solar are at night, when energy use is lower (though will that remain the case when everyone's electric car is then charging?). Also, winters drive heating demand. Perhaps some small amount of storage makes a big difference; e.g. if we could store a week's worth of power, that takes us through all but the biggest troughs in power generation, and you need less nuclear (though again, not sure how that works with winters).

I'm not nuclear-crazy, if we could do solar+wind+batteries, why not. But I find the renewables lobby just says "yeah prices will fall, we will solve energy storage, just go all in on renewables, perish nuclear", which just seems like crazy wishful thinking. Whereas nuclear is always described based on 1970s technology and with the most exaggerated (un)safety numbers.

There’s nothing wrong with more energy. People seem to assume that we need X amount of energy and if we can provide X amount of energy with one source or the other, we don’t need any more energy. That’s ridiculous. Energy is a commodity like anything else, and when you have more of it, you can do more stuff.

How many industries are throttled on energy cost/availability and nothing else? Crypto mining for sure. What else? Aluminium smelting perhaps?

For whatever reason, energy production seems to be about meeting demand, rather than finding use for surpluses.

Two ideas: desalination and direct air CO2 capture plants? Though maybe the primary bottleneck isn’t lack of energy, and you don’t want all that expensive equipment idle while you are waiting for excess electricity from renewables.

Make electricity free and I can decarbonize steelmaking entirely.
Re:Will the climate crisis force America to reconsider nucle... by belorn on Wednesday November 10, 2021 @08:38AM (#29174469)
In context of Sweden:

Steel production require massive amount of energy, especially if you want to go coal free. Forest products also depend on cheap energy. An other area is concrete production.

After those I suspect it is food production. Read somewhere that fish farms on land is suffering in particular.

Basically any production dealing with raw materials.

Re:Will the climate crisis force America to reconsider nucle... by rich_sasha on Wednesday November 10, 2021 @11:05AM (#29176229)
Can you use these if they are intermittent and unreliable?

I'm thinking, maybe we get to the point where we have lots of nuclear humming at a constant (ish) rate, and some much cheaper, but unreliable renewables. Can steel mills start and stop? Forestry, ming etc. work on the schedules of wind and sun?

Sounds tricky for sure. Especially because then, renewables will have to compete with marginal cost of nuclear (which is drastically lower than average, since it doesn't include the massive cape, fuel is cheap etc.)

Re:Will the climate crisis force America to reconsider nucle... by belorn on Wednesday November 10, 2021 @02:03PM (#29178944)
Employees cost money, as does buildings and storage. They can shutdown for periods when the energy cost is high but it hurts profitability and the economical viability.

The steel industry here try to build next to hydro, in areas where the price is relative low. The price point can differ by more than 100% when we compare the cheapest regions with the most expensive, for reason that has to do with transmissions. There is also experiments with hydrogen.

A few paper mills have cut down on employees, and in some cases shutdown the plants during periods of low wind.

Food production can't shutdown. A fish farm need to keep the water at a set temperature or the fish dies. Greenhouses that depend on artificial light can't just close down or the plants dies.

I would say that the answer is mostly a no. Short term some industries can adapt a little while waiting for the energy prices to stabilize, but long term it is a hard sell to have employees and building just sitting around.

I don't know off the top of my head how much of industry runs 24/7 and how much is just during the day, but it's possible that "solar power only works during the day" and "factories operate during the day when their workers are awake and at work" will both sort of work out together.
Re:Will the climate crisis force America to reconsider nucle... by SeanSpearo on Wednesday November 10, 2021 @10:49AM (#29175982)
That's because too much power overloads the power wires. You can only get that by making surplus, and when surplus occurs a lot of that power is lost from overload. And before you say to upgrade the wires, that would cost a lot of money and be an infrastructural nightmare.

Would hate to think of how much worse crypto would be If power was free.

Mining for materials, waste products, waste heat, noise.

Already have regular extended family complaining about the huge number of noisy shipping containers in their communities. These are middle of nowhere towns.

Re:Will the climate crisis force America to reconsider nucle... by philwelch on Wednesday November 10, 2021 @11:50AM (#29176892)
See, this is exactly what I'm talking about. People have the intuition that it's somehow inherently virtuous to use less energy, even if it's from clean and sustainable sources.
Re:Will the climate crisis force America to reconsider nucle... by philwelch on Wednesday November 10, 2021 @07:41AM (#29173997)
That’s mostly because we don’t use a lot of renewables though.
Re:Will the climate crisis force America to reconsider nucle... by Hypx_ on Wednesday November 10, 2021 @05:57AM (#29173325)
There's only two viable paths to a zero emissions society. One is nuclear and the other is hydrogen. We have to pick one or the other (or both) as all other ideas have fallen far short of the goal.
Re:Will the climate crisis force America to reconsider nucle... by rich_sasha on Wednesday November 10, 2021 @06:18AM (#29173456)
Well, I don't know. Are batteries + renewables a prior impossible? I can't see why, especially if we're talking about utility-scale batteries, which could be heavy and bulky.

My point is we don't have them at a competitive price, and yet the renewables people insist we definitely well. We might, we might not.

Re:Will the climate crisis force America to reconsider nucle... by Hypx_ on Wednesday November 10, 2021 @12:43PM (#29177630)
People who looked at that strategy have realized that you need way more energy storage than originally thought. Especially in places that need winter heating.

The only way we can get there at a reasonable cost is via hydrogen energy storage. The other ideas are orders of magnitude too expensive.

For the UK, the solution might look something like this: https://hydrogeneast.uk/study-explores-uks-geological-hydrog...

One of the big issues with nuclear plants is that they aren't very flexible in terms of their energy production. Their production is super steady, so what happens when there's a huge peak in electricity demand at 6 pm when everyone gets home? Fossil fuels are great for their relatively short start up time. Maybe renewables + batteries could somehow fill this niche?
Re:Will the climate crisis force America to reconsider nucle... by melling on Wednesday November 10, 2021 @07:16AM (#29173834)
So what you’re saying is it would be best for base load and only good for about 75% of our electricity?

Imagine if we had said that 40 years ago. We’d be talking about getting to net zero by 2075 instead of 2050.

Now we’re still waiting for renewables

Re:Will the climate crisis force America to reconsider nucle... by smileysteve on Wednesday November 10, 2021 @08:30AM (#29174394)
Power plants have giant flywheels and batteries (vanadium redox) that can help peak demand. Hydroelectric can also be managed for this.

"...when there's a huge peak in electricity demand at 6 pm when everyone gets home?"

The entire electrical generation industry knows all this. They know when clouds are coming and when wind will stop and model it all. Pricing information is sent ahead of time and plants know if they will be required to spin up or spin down well in advance. Especially something as simple as "everyone gets home at 6pm at a regular time every weekday". It is easy for plants with slow ramp times, such as nuclear and coal, to plan for that.

I still havent heard of a solution to nuclear waste. In my opinion nuclear could be the transition technology though. Also nuclear is not cheap at all from what ive read..
Re:Will the climate crisis force America to reconsider nucle... by rich_sasha on Wednesday November 10, 2021 @07:20AM (#29173857)
I remember reading that nuclear costs about the same as fossil fuel + carbon capture, and, at current prices, much less than renewables + enough storage to make them continuous. This to me is the fair comparison. Further, I'd rather live near a nuclear plant than a coal plant sitting on tons of compressed CO2, ready to pop and asphyxiate everyone in the vicinity.

I agree storage is a problem, maybe not as big as it is generally made out, but even then, would I rather struggle with nuclear waste, or millions of tons of CO2 in the atmosphere? The latter will lead to a planetary-scale disaster, the former at worst to minor regional ones.

Re:Will the climate crisis force America to reconsider nucle... by ciphol on Wednesday November 10, 2021 @09:09AM (#29174769)
The solution to nuclear waste is "status quo". As far as I know, no person has ever been harmed much less killed by waste from a nuclear power plant.

Also, the dangerous isotopes are also the ones which decay most quickly. Let the waste sit for 300 years and it will be no more radioactive than the uranium ore it was originally mined from. At that point you can dump it back into the uranium mine, or else keep it anywhere else you think would be safer than an abandoned uranium mine, the risks are miniscule either way.

Re:Will the climate crisis force America to reconsider nucle... by ostenning on Wednesday November 10, 2021 @10:05AM (#29175336)
But generally this isn't what happens right? Often the waste gets dumped in surrounding oceans of Europe.

Nuclear is an amazing source of cheap and clean energy, but the problem has always been the management of Nuclear plants and waste that has resulted in environmental disasters.

I'm honestly not confident in anyone to handle the Nuclear properly, not private enterprise or government. As history tells us, nobody can seem to get it right 100% of the time.

Maybe advancement in technology means safer Nuclear plants and easier to manage waste, but maybe they thought the same thing when they built the Fukushima or Chernobyl plants.

History has a knack for repeating itself.

> waste that has resulted in environmental disasters

Have you ever seen a coal ash pond? Do you know how many there are? Do you know what is in them? (There are thousands, they are filled with arsenic, heavy metals and often radioactive waste, and they are all across the landscape.)

Have you seen how brown coal is mined? Obliterating entire towns and villages as a matter of routine? All waste by all nuclear reactors in the world would fit in a single brown coal open pit and would do less human and environmental damage...

Sorry, you are right, let me clarify my answer. Dumping of radioactive waste in Europe was prevalent back in the 80's, but the effects of this are still felt today. Just recently a large number of barrels were found in the Baltic [1]. Japan also has announced it will be dumping large quantities of radioactive material into the ocean, because they simply don't know how to handle the situation any better [2]. The Japanese government claims that they intend to make the waste safe, personally I wouldn't trust such a statement.

> Have you seen how brown coal is mined? Obliterating entire towns and villages as a matter of routine?

I never mentioned the environmental impact of burning or mining coal, nor did I claim it was any better or worse than nuclear power.

I'm highlighting that mismanagement of Nuclear has historically been a problem and I don't feel confident that those mistakes aren't repeated in the future.
