The SMNR format suffers from being small and therefore difficult to be cost effective and that renewables are 4 times as cheap. Not easy to make money in this environment. cleantechnica.com/…/nuclear-energy-free-market-ca…

scratchee@feddit.uk 1 year agoIf it was a matter of half the price then nuclear would be the clear winner. Paying double to get stable power rather than variable power is currently a clear win.
Nuclear has a lot of baggage on top of being more costly (eg public fears, taking a lot longer to get running, building up big debts before producing anything, and having a higher cost risk due to such limited recent production), if it was just a simple “pay twice the price and you never need to worry about the grid scale storage” then nuclear would be everywhere.

Yeah, one justification I’d heard was that it was a cheap and low risk way to revive the industry enough for bigger projects, but I’m not sure that’s particularly compelling.
Greyghoster@aussie.zone 1 year ago
Sounds like a very expensive argument to invest billions on the hope that something might happen 😬. Hope it’s not my money.
scratchee@feddit.uk 1 year ago
Literally every industry starts that way. Start small and scale up. Nuclear’s special because we did it once and then almost completely stopped building them globally for so long that the capability faded away.
The tech shifted in the meantime, so even the knowledge that was preserved is for designs we wouldn’t want to build today.

The last US nuclear plant built went seven years behind schedule and seventeen billion over budget.
That sets a large amount of weariness in everyone to commit to making another, unfortunately.

Yeah the poster above you is wrong. Solar is WAY less than half the price.
scratchee@feddit.uk 1 year ago
Yes, especially right now. To be fair that’s mostly because solar is doing great as far as scale goes right now. Nuclear has near zero scale and lost all experience, so it’s more expensive than ever.
agressivelyPassive@feddit.de 1 year ago
It’s been a while since I looked it up, but back then the projected price of SMR energy was about double the cost of current solar.
I’m not sure, if that changed much over the last month.
Anyway, wind, solar and hydro combined can produce energy pretty inexpensively. The power grid isn’t exactly simple with nuclear reactors either, so it’s not like you’re winning that much from this perceived reduction of complexity.
scratchee@feddit.uk 1 year ago
I’m certainly not arguing nuclear is a panacea that everyone in all the governments have somehow missed (even ignoring the risks mentioned its only a potential fit for a relatively thin slice of the grid these days).
The point I’m making is that currently there are energy production needs we effectively can’t fulfil with renewables because the costs would be impractical. Some of those do fit nuclear better currently. Nobody really cares about that though for 2 reasons: 1. There’s plenty of opportunities that renewables still can fill and 2. The cost of storage is projected to drop a lot over time, which should fill in the gaps and squeeze out many of the last opportunities for nuclear.
Quite possibly by the end the remaining slice where nuclear could fit will be so thin it can’t actually sustain an industry (and given the industry has been half dead for decades, it’d take a big win to justify reviving it), so yeah, at the moment it looks like lots of risks and questionable rewards. Nonetheless the current prices aren’t really the problem, it’s just that things are risky, and projected to get worse over time, so why invest?
Ironically it’s not that different to the fossil fuel industry, just with a lot less existing infrastructure.

One massive point that most people are completely blind to is that with energy considerations we are aggressively pursuing two very different goals that in many regards are directly at odds with one another.
The first goal is electrification, which can largely be accomplished by increasing renewables, investing in battery technology, etc. But in the US, we have also been accommodating the desire for electrification by massively increasing natural gas capacity.
The second goal is decarbonization. This requires us to also nix natural gas from the equation at some point. In addition to the problems others have already mentioned (like the fact that renewables aside from hydro are not viable base load power options right now), there is a significant chunk of our energy infrastructure that simply cannot be satisfied in any regard purely with renewables. Like the huge number of industrial processes that need process heat to achieve their end product.
So the best solution is energy portfolio diversity. We can steadily continue to phase out heavy polluters for electrification, but if we want to truly decarbonize, industry demands a solution that can still produce high heat without emissions. Nuclear is a woefully under-exploited technology in that regard, but it is potentially a great solution.
scratchee@feddit.uk 1 year ago
Yup, it’s hard to predict what the mix will look like, but 100% solar would be a very costly solution for sure.
I used to be very pro nuclear, and I still think it could have been a big piece of the puzzle, but I do worry we’ve missed the boat, it could’ve been the first wave of decarbonisation 20 (or more) years ago, I’m not sure how well it can compete growing from almost nothing now with the renewables eating all the easy money. nuclear plants need to run 100% to be successful, and renewables have dropped a bomb on the concept of baseline demand. Maybe as we kill gas we’ll have to start giving massive bonuses to on demand power that isn’t pumping co2, but the absolute lid on that market is the price of storage, which is high enough now, but will drop, it’s unclear how long the gap for nuclear will exist there.
Certainly willing to be wrong though, there’s lots of unknowns with nuclear, quite possibly it could be multiple times cheaper if only we’d invest into it properly.

BASF can do it, have been able to for ages, they’re switching their feed stocks around depending on price point and push come to shove they could run on nothing but literal potatoes. The Ukraine war was a bit of an extreme situation for them because their piping wasn’t set up for a massive drop in gas availability but they were able to cut consumption by IIRC 60% without affecting production rates.
Steel smelters will have to be rebuilt completely to run on hydrogen and side note it’s more efficient to turn electricity into hydrogen and then smelt than to try and reduce with electricity directly. All of that costs money but by this point it ain’t exactly rocket science.
