Yeah no shit. We already knew nuclear was not profitable, but it’s clean & makes tons of power, so it’s a good deal for everyone that isn’t a business & wants cheap & clean energy.

[-] vaseltarp@lemmy.world 11 points 1 year ago

The point of this research is that renewable are cheaper. So why would we invest our money in the more extensive option?

[-] tdawg@lemmy.world 24 points 1 year ago

Government isn’t business. It should not be chasing a profit margin. The decisions should be around sustainability, ecological friendliness, and robustness against failure

Profitability is so much not the point here and also, there's no reason for different energy production sources (especially ones that are base power vs incidental power) to be in conflict. Do both of them.

Nuclear is the future. Stop trying to deny it. We should all be running it by now this shit was made like 60 years ago. But no, we'll just eat smog I guess. Damn my feeds are kind of depressing today.

[-] GiddyGap@lemm.ee 15 points 1 year ago

Fission is today. Fusion is the future.

[-] Sanctus@lemmy.world 17 points 1 year ago

It blows my mind we are avoiding this? You want jobs? Clean stable energy? Its fucken here dude. Just build some plants. They only need to be properly maintained to avoid disaster. If we truly are an intelligent species that should be easy as hell.

[-] mdd@lemm.ee 16 points 1 year ago

They only need to be properly maintained

And there is the issue.

"disaster" is a big word for what happens with a nuclear accident.

The fire in Hawaï or the climate change are disasters. A hurricane is a disaster. Chernobyl or fukushima were disasters in the media much more than in the reality of things.

Cars kill more people every year than nuclear energy did since we use it. In fact, this is still true even if you account for atomic bombs...

Stop all the hate for nuclear. It's just a way for the fossil fuel industry to cause infighting among those of us who care about the climate. If we can make energy free or close to it, we should. The closer everything comes to being free the better.

[-] gmtom@lemmy.world 8 points 1 year ago

People pushing nuclear is a way for fossil fuels industry to keep us reliant on them for the next 20 years while we build power plants.

That's not difficult. Nuclear is extremely expensive.

With renewables you just sell it to the grid for whatever gas generated electricity is going for. Which is currently still a fucking lot. Thanks Russia.

Gotta love anti nuclear activists getting more and more desperate. You're being decarbonised. Please do not resist.

Nah, the power company likes the profits from nuclear way better.

The secret is that they can bill the ratepayers for all the cost overruns, while keeping the extra profits on the cost-plus construction contract for the shareholders.

(Source: I'm a Georgia Power ratepayer being absolutely reamed for Plant Vogtle 3 and 4, and the Georgia Public Service Commission isn't doing a single goddamned thing to hold Georgia Power to account or to help people like me.)

More profitable AND safer. Humans are too stupid, lazy and bureaucratic to use nuclear.

If we had an energy system owned by the people and not ran for profits, nuclear would be a viable, and probably even the preferred, option. We do not. We're probably going to have to fix that to get a practical and reliable clean energy grid.

[-] wewbull@feddit.uk 9 points 1 year ago

No, it would just bankrupt the state. Just because something is state owned, doesn't mean the cost vanishes.

Everyone seems to be focused on electricity production, but ammonia production (ie nitrogen fixation) for fertilizer is often overlooked. Right now it is accomplished mostly with natural gas. If we're supposed to do it instead with wind and solar, we're going to have to rely on simple and inefficient electrolysis of water to generate the hydrogen needed for the Haber process. Nuclear power plants have the advange of producing very high temperature steam, which allows for high temperature electrolysis, which is more efficient.

When you consider our fertilizer needs, it becomes clearer that nuclear power will have to play the predominant role in the transition away from fossil fuels.

[-] schroedingershat@lemmy.world 13 points 1 year ago* (last edited 1 year ago)

No on all fronts.

The only reactor designs with any sort of history don't produce steam at high enough temperature for the sulfur cycle and haber process.

The steam they do produce costs more per kWh thermal than a kWh electric from renewables with firming so is more economic to produce with a resistor.

Mirrors exist. Point one at a rock somewhere sunny and you have a source of high temperature heat.

Direct nitrogen electrolysis is better than all these options. It's had very little research but the catalysts are much more abundant than hydrogen electrolysers and higher efficiencies are possible.

Using fertilizer at all has a huge emissions footprint (much bigger than producing it). The correct path here is regenerative agriculture, precision fermentation and reducing the amount of farmland needed by stopping beef. Nitrogen electrolysis is a good bonus on top of this.

This is such a weird thing to research because a government (or governments) can directly or almost directly control what is profitable in a society based upon what is needed.

Until we are able to sort out the cost/tech to make a green-sourced grid (such that the role of utilities is to capture surpluses from when the sun shines and the wind blows and sell it back when transient sources aren't producing) nuclear is going to be an important part of a non-carbon-producing energy portfolio.

Already it's cheaper to bring new solar and wind online than any other sort of electrical production; the fact that those are transient supply sources is the last major obstacle to phasing carbon fuels entirely out of the grid. If nuclear can be brought safely online it could mean pushing the use of fossil energy entirely into use cases where energy density is critical (like military aviation)

[-] agitatedpotato@lemmy.dbzer0.com 9 points 1 year ago

Profit doesn't equal good. Renewables take a lot of materials and fabrication to upkeep. Im sure theres more money to be made in renewable than there is in nuclear, that doesn't imply one is better than the other.

[-] Neato@kbin.social 9 points 1 year ago

If we measured the amount of destruction to our environment that fossil fuels cost long-term I bet they'd stop being profitable really quick.

Its a relatively recent development however since the panels and turbines got quite a bit cheaper. Nowadays solar/wind ends up fairly similar and Nuclear is about 3x the price (with gas being more and coal being nearly 7x more). That is only some of the story as you need some storage as well but it doesn't end up in favour of Nuclear. 15 years ago Nuclear was a clear win, its just not anymore the price of Solar come down fast.

What about when the grid is almost entirely renewables? Is nuclear cheaper than just storage? What about storage one it's already been implemented to the point of resource scarcity?

[-] zik@lemmy.world 11 points 1 year ago* (last edited 1 year ago)

No, nuclear is always more expensive in real world conditions. Places with mostly renewables plus in-fill from batteries and transient gas generation are a lot cheaper than nuclear. eg. South Australia.
