Nuclear’s big selling point is that the sun goes down. Batteries have apparently missed that memo: they keep getting cheaper, better, and more efficient. Storage won’t solve every grid problem overnight, but pretending today’s limitations are permanent is a strange way to plan tomorrow’s energy system.
another big selling point of nuclear is it’s easy to drop in at old coal plants that already have grid connections ready to go.
pretending today’s limitations are permanent is a strange way to plan tomorrow’s energy system.
how long are you willing to wait for perfect energy storage?
obviously battery tech will improve, but the point is we cannot afford to assume that problem will be solved 100%, meanwhile experiencing more and more irreversible damage to our environment. We need to put our eggs into all clean energy baskets to get off CO2 as soon as possible. Not whenever battery tech happens to be ready to handle everything.
“it’s easy to drop at a place that has grid connections”
Funny, because solar or literally any other plant will also benefit from having existing connections, and all of them are easier and cheaper to build than nuclear.
Nobody’s asking us to bet on miracle batteries: Wind and solar paired with storage are already cheaper than building new nuclear. Reusing a coal plant’s grid connection doesn’t magically make a reactor cheap or quick to build. If speed and CO2 matter, follow the numbers, not the nostalgia.
Maybe cheaper in money terms, not others, first of all space.
But how much would cost to build a solar farm with the same output of a nuclear plant, both on days and night ?
No, in my world tomorrow’s grid uses whatever delivers reliable electricity at the lowest total cost: solar, wind, hydro, geothermal, storage, and yes, nuclear if it can compete. This isn’t a religion with approved energy sources. It’s an engineering problem with a price tag, and nobody gets bonus points for glowing in the dark.
Exactly, this is an engineering problem. You’re talking it like it’s an accounting one. Reliability, emergency use, redundancy, generating potential and universal scalability are the most important factors. Cost is a completely separate issue governed by separate factors, many of which are 100% artificial.
Cost is the single largest factor in the deployment of new power plants, and solar is just impossible to match right now.
You could spend literally decades and billions building a nuclear plant, or start deploying solar right this minute and immediately reap the rewards of that investment.
You could say that the numbers scribbled down on pieces of paper next to a dollar sign are artificial or miscalculated, but the invested manpower and resources and time (and a large number of other consequences) are all very real, and translate into a cost.
yes i know that, genius. the point is that is not an argument people are using for nuclear. it’s a blatant straw man from someone clearly not engaging in a goood faith discussion.
That’s kind of the point; it’s not a straw man, it’s saying that the options should be considered on their merits not on irrelevancies. “There are no bonus points added to the scoring just because nuclear looks cool when it glows”
Nuclear is simply incompatible with renewables, if the price tag is of any concern to you. Nuclear reactors take long and cost a lot to build, still aren’t cheap to operate if you include the infrastructure cost of getting, handling and storing the fuel, can’t respond to changing demand quickly and are centralized.
Nuclear power plants need subsidies over their whole life, mainly to handle the risk inherent with nuclear fuel and the finincial risk of having to handle spent fuel for centuries to come.
Nuclear power plants need to run at full power, which costs money every time renewables are pushing the energy price into the negatives.
Nuclear power plants need a centralized power grid.
Renewables work in exactly the opposite way. They are cheap to build and maintain, they are variable and decentralized. So to use renewables effectively, you need to build a decentralized grid and ideally on-premise energy storage.
Renewable energy simply wins in terms of cost, risk-management and scalability. So the energy grid of the future will be purpose-built to accomodate renewable energy. Trying to force nuclear energy generation into that mix only makes sense, if you have a clear, non-monetary reason to do so, like enriching uranium for bombs. For strictly commercial use, nuclear power is dead.
Nuclear is simply incompatible with renewables, if the price tag is of any concern to you. Nuclear reactors take long and cost a lot to build, still aren’t cheap to operate if you include the infrastructure cost of getting, handling and storing the fuel, can’t respond to chaning demand quickly and are centralized.
The fact is that the price tag is not the only factor.
It is true that a 1000 MW nuclear plant cost about 10 times the equivalent solar field (about 6-9 billions for the nuclear plant Vs about 800 millions for panels) but at this point you use about 15 square Km to just match the output of the nuclear plant, with no storage, and only in the best case scenario.
In a real case scenario the price tag of building a solar field that could replace a nuclear plant is probably not that different anymore.
To produce the same amount of power in every condition you could not install the exact amout of panels, you need way more (double ? triple ?) with the associated costs and space requirements.
And then you need batteries to be able to offer energy also at night and to store energy for the days when the sun is not enough to produce the energy required.
I would say that to match a nucler plant a solar field would cost about half of it for the same power generation but with the additional problem that you need way more space, which itself is a cost.
Nuclear power plants need subsidies over their whole life, mainly to handle the risk inherent with nuclear fuel and the finincial risk of having to handle spent fuel for centuries to come.
We have nuclear power plants that uses less problematic fuel which is easier to handle and less risky.
Nuclear power plants need to run at full power, which costs money every time renewables are pushing the energy price into the negatives.
True, but when the renewables are not producing enough ?
Nuclear power plants need a centralized power grid.
Like a solar farm.
Renewables work in exactly the opposite way. They are cheap to build and maintain, they are variable and decentralized. So to use renewables effectively, you need to build a decentralized grid and ideall, on-premise energy storage.
No, they work in the exactly same way. What is different is that renewables can be made decentralized. Solar panels on the roof produce only for the house, not for the power grid (even if you can connect them to the grid to fill in the surplus).
I think you are comparing a nuclear plant with the small panels you install on your roof but you cannot make such comparison.
So the energy grid of the future will be purpose-built to accomodate renewable energy.
As far as I remember, what was told me when I worked in the field was that power grids does not care about the source, only the power: a power grid do not care if the 10 Gw power it transfer comes from a nuclear plant, a solar farm or from a squirrel on a wheel.
And the grid is already ready, we are already able (ok at least here) to send to the grid the surplus generated by the solars panels on the roof. And adding the batteries will not require anything done on the grid itself (at least this is what my collegues said).
Trying to force nuclear energy generation into that mix only makes sense, if you have a clear, non-monetary reason to do so, like enriching uranium for bombs. For strictly commercial use, nuclear power is dead.
What about being sure that a 5 days of bad weather cannot stop a society ?
First, you don’t have to install the solar capacity in one huge blob. Solar farms also don’t have to be the only use of the land. You can still farm crops that like shade, you can hold cattle, build the energy storage right beneath the solar farm, a car park or what have you. There is also a lot of currently “wasted space”, such as roof tops or existing car parks. There are also swimming solar pannels that have the added benefit of keeping lake temparatures in check in the summer. You also have wind turbines that can contribute their fair share to the energy mix. So no, you don’t need to build huge over-capacity and you don’t need to bulldoze huge swaths of land to install solar. And the price to build solar and battery storage is still going down.
Where are the nuclear plants that use “safer fuels”?
Renewables are cheaper to build and run, meaning that renewable energy is always cheaper than nuclear power. You’d need to artificially limit the amount of renewables companies are allowed to build or subidize nuclear, otherwise renewables will price nuclear out of the market.
No, solar farms don’t need centralized grids nearly as much as nuclear power does. What is much more important for renewables is monitoring the local grids, so they don’t get overwhelmed by people providing power to the grid with their solar pannels.
And people already absolutely do provide power to the grid with their own solar pannels, you denying that just shows that you haven’t mich thought about/experienced local “grass roots” energy production. In Germany, the capacity of the local grids is one of two big hurdles renewable energy production is facing right now. Commercial and private energy producers are complaining that the utility companies are forcibly cutting their power plants from the energy grid to stabilize it.
And like I said in other comments already, hydrogen/natural gas power plants are a much better fit to handle extended lulls in wind and solar.
And turns out nuclear has a few competitive advantages over solar. They are both great and serve different purposes.
Nuclear’s big selling point is that the sun goes down. Batteries have apparently missed that memo: they keep getting cheaper, better, and more efficient. Storage won’t solve every grid problem overnight, but pretending today’s limitations are permanent is a strange way to plan tomorrow’s energy system.

“it’s easy to drop at a place that has grid connections”

Nuclear is dead but for niche applications.
Nobody’s asking us to bet on miracle batteries: Wind and solar paired with storage are already cheaper than building new nuclear. Reusing a coal plant’s grid connection doesn’t magically make a reactor cheap or quick to build. If speed and CO2 matter, follow the numbers, not the nostalgia.
“Cheaper” is not the most important metric.
Maybe cheaper in money terms, not others, first of all space.
But how much would cost to build a solar farm with the same output of a nuclear plant, both on days and night ?
In your world, is “tomorrow’s energy system” exclusively solar/hydro?
No, in my world tomorrow’s grid uses whatever delivers reliable electricity at the lowest total cost: solar, wind, hydro, geothermal, storage, and yes, nuclear if it can compete. This isn’t a religion with approved energy sources. It’s an engineering problem with a price tag, and nobody gets bonus points for glowing in the dark.

Reliability, emergency use, redundancy, generating potential and universal scalability are the most important factors. Cost is a completely separate issue governed by separate factors, many of which are 100% artificial.
Dude, the cost is the final decision point after all those concerns are handled…
You’re stringing worlds together at this point.
Cost is the single largest factor in the deployment of new power plants, and solar is just impossible to match right now.
You could spend literally decades and billions building a nuclear plant, or start deploying solar right this minute and immediately reap the rewards of that investment.
It’s a no-brainer.
I would say that even availability is an important factor, maybe more important then the mere price.
It ultimately gets translated into costs, that’s what greenlights a project.
But it doesn’t need to be one or the other. The more diverse the grid the better. I’ll also say again, cost on both sides is mostly artificial anyway.
Again, you’re stringing words together.
Cost is a very real measure.
You could say that the numbers scribbled down on pieces of paper next to a dollar sign are artificial or miscalculated, but the invested manpower and resources and time (and a large number of other consequences) are all very real, and translate into a cost.
where the fuck did anybody say that?
“Glowing in the dark” refers to nuclear power sources. Hope this helps.
yes i know that, genius. the point is that is not an argument people are using for nuclear. it’s a blatant straw man from someone clearly not engaging in a goood faith discussion.

You are mixing up many different things.
First, you don’t have to install the solar capacity in one huge blob. Solar farms also don’t have to be the only use of the land.
