| Of course the article is just a puff public opinion piece. It doesn't change the economics: Point ONE: nuclear is more expensive CURRENTLY that solar/wind. SOlar/Wind is currently the cheapest by far, and here's the scary thing for gas turbine: solar + storage is very close to druopping under gas combined cycle generation. Look up Lazard 2023 LCOE study. Solar/Wind have dropped to 24$ per MWHr. The cheapest nuclear produces is $141/MWHr. That's right, nuclear is almost 600% more expensive. Point TWO: Say you miraculously got 100 billion dollars through congress for new plants to start immediate projects. Not a single reactor will come online for 10 years. Now, look at the cost improvement rate of solar, wind, and storage for the last 10 years. 10% year-on-year improvements or more. Even if we had half of that for the next 10 years (and there will be 10 more years of cost improvement), solar / wind very likely will be HALF the current cost. So you'd have 100s of nuclear plants come online in 10 years generating electricity that costs 10-20x more than electricity from wind/solar. That simply is not a viable national power strategy. If we had these plants already because construction started in the year 2000, that would probably be a different story. The only hope for nuclear is probably in about 15-20 years where the cost improvement curves finally stabilize for wind/solar, and then a stable price point can be targeted with new nuclear designs. I personally think that only something like a novel MSR/LFTR which can scale down to mass producable sizes, uses all the fuel, breeds. doesn't have solid fuel rod reprocessing and waste transport/storage, and can use the Brayton cycle for more efficiency has a chance of competing with mature solar/wind. Puff pieces like this are really about the current nuclear plants and keeping them on funding life support, which I generally support for now. The industry sees that Lazard LCOE curve just like any other person would: do you want to pay solar/wind costs for electricity, or 6x that for nuclear? The existing nuclear industry can't survive without subsidies. |
From your own source, the Lazard 2023 LCOE study: "Most LDES (long duration energy storage) technologies have not yet reached commercialization due to technology immaturity and, with limited deployments, seemingly none of the emerging LDES technologies have achieved the track record for performance required to be fully bankable."
Ideally we'd have a combined approach - nuclear base load, renewables and grid scale storage to reduce the number of expensive nukes we need. That way you'll always have at least some power. But we don't have grid storage yet. And without storage, there's not much point in offsetting the output of nuclear plants, since fuel costs are so minimal - you might as well run all the nukes full tilt, all the time. So really, the only sensible thing to do is build primarily nuclear, and renewables in proportion to our ability to deal with wildly fluctuating energy supply.
