When I first read the titile, I thought that the US is going to have to build A LOT to triple global production. Then it occured to me that the author means the US is pledging to make deals and agreements which enable other countries to build their own. Sometimes I think the US thinks too much of itself and that’s also very much part of American branding.

Where are my renewable bros at? Tell me this is bad.

  • Today, there is 413GW of nuclear capacity globally. Of that, 57GW is in China.

    China plans to reach 300GW of nuclear capacity by 2035. Assuming linear growth, that number will be around 550GW by 2050 (more than double the current global nuclear capacity) There are currently 57 nuclear power plants under construction. 21 are in China. 1 is in the US.

    This US pledge is basically useless.

    Nuclear power isn’t bad. I used to be anti-nuclear energy because of the specter of Chernobyl, 3 mile island, and Fukushima. But learning more about it, there haven’t been many actual problems with nuclear energy.

    Chernobyl happened because of mismanagement and arrogance. 3 mile happened because of a malfunction. Fukushima happened because of mismanagement and failure to keep up safety standards in case of natural events.

    These are all things that can be mitigated to one extent or another. it’s much cleaner than other forms of energy, outputs way more than solar or wind, and with modern technology can be extremely safe. I think we should be adopting nuclear, at least as a stopgap until renewable tech reaches higher output in efficiency.

    Kinda annoyed that these investments are going into foreign countries, when we are one of the major contributors to greenhouse gas. We should be building them here first to mitigate our own ghg contributions, then helping smaller countries build theirs.

    I do still have concerns about waste removal and storage tho, but I’m sure we could figure that out if we actually wanted to. But I doubt we do, because “dA cOsTs” or some shit.

    • Chernobyl had such a far-reaching environmental impact. Beyond even the radioactive pollution stuff, it scared everyone away from nuclear power and back to fossil fuels for energy production. I sometimes wonder where we’d be wrt CO2 levels if nuclear energy adoption had continued along the same trend as it was before Chernobyl. Would we have had substantially more time to mitigate climate change? Maybe we’d have been in the same boat (or an equally bad boat) due to other factors; maybe it would have stymied renewables even more due to already having a readily available and well-established alternative to fossile fuels in nuclear power. Idk. But if someone wrote one of those what-if alternative history novels about the subject, I’d read the heck out of it.

    • Anyone still worried about the safety of the method is an ignoramus. “Dying slowly to lung cancer and the environment cooking me alive is so much better than the one-in-a-billion chance of having to eat some prussian blue”

      Waste removal is my biggest concern. Unless the plans to expand also come with ways to recycle the waste, we’re just setting ourselves up for giant exclusion zones throughout the globe, most likely in small countries where the plants are imposed on them by foreign economic powerhouses and then they’re told to figure the waste out themselves.

      Not to mention “just bury it” is neither futureproof nor is it good for the non-human inhabitants of our planet; sure if those concrete containment cysts in the desert ever fail it will “only” be leaking radiation into the desert, but any desert is still home to hundreds of species of living things and its own complex ecosystem. “Desert” doesn’t actually mean “devoid of life”; there are no good locations to bury it and forget it.

      Let’s talk about the absolute devastation mining rare materials does to ecosystems and the exploitation of third world countries that it’s led to. We’re already implicated in so much violence against the earth itself and colonialist exploitation, and I’m supposed to support gods know how much more of that for Uranium from Kazhakstan (45% of the worlds’ production in 2021)? That’s basically begging for more forever wars over energy resources in the middle east.

      “We’ll figure out long term solutions after the infrastructure is put in place” is how we got to where we are with fossil fuels AND landfills.

      I’ll fully support any plans to make a push toward nuclear, but the foremost concern of that push should be waste recycling. After that’s figured out, everything else is small potatoes. It would even make the long-term costs cheaper than fighting for new material and figuring out million-year half-life hazardous waste disposal. A nearly unlimited energy supply that doesn’t fuel wars and is safer than the current system? Sign me the fuck up.

      • Regarding waste; nuclear waste can be turned into diamond batteries.

        If they manage to release, the idea is that small cell batteries can self-recharge themselves practically forever (20,000ish years?). Battery dead? Remove it, swap it, wait. Battery dead? Insert the one you removed previously, the Uranium inside replenished the charge.

        Neat stuff given that it is made from waste byproduct.

        • That’s cool as fuck! Now, how do we implement it?

          I should have been a little more clear: I’m not worried about a lack of ways to properly neutralize and dispose of the waste, I’m concerned that they will not be implemented because they are deemed unprofitable.

          Already the U.S. runs nuclear power, and yet we still haven’t implemented waste recycling (as of 2022 iirc the article I read); why? Presumably because ultimately it does not serve the interest of capital. So get plans to create that infrastructure into effect, and I’ll get on board with any expansion. Until that happens, it’s just hopping on the dick of this new tech because it’s bleeding edge and assuming the infrastructure to handle it will follow (which has worked so well for e-waste and cars and fossil fuels and plastics and…)

          Not that sticking to fossil fuels in the meantime is a better alternative. We should focus on energy production that doesn’t have the potential to immediately kill us should the waste-containment fail: solar, wind, geothermal, hydroelectric. Hell, we already have stockpiles of a majorly combustible fluid that requires an ever-increasing amount of energy to harvest, why not exchange it for one that doesn’t also cause biosphere collapse as a side-effect: Hydrogen?

          None of these are environmentally friendly either, and so I’d still prefer to see nuclear in the long run instead. Strip-mining Uranium is still better than the massive amount of mining needed to get the rare metals necessary for solar at large scales, wind farms are destructive to local wildlife, hydrogen can explode and needs a constant source of water to produce while requiring a way to dispose of all the sediment generated, dams and massive water reservoirs are a blight on the landscape and disrupt entire ecosystems; I have no clue how geothermal is even harvested, but if the other renewables are anything to go by…

    • It’s not “da costs”, it’s actually really, really really expensive to build new nuclear reactors. Most of that comes from increased labor costs, which in turn have ballooned largely due to increased regulation and oversight requirements, which I would argue is not something we should do away with.

      I wouldn’t necessarily mind having a reactor or two acting as base generators especially during the winter, but

      1. In Germany we’ve been searching for a secure waste site since the first reactor went online in 1957. If we haven’t found it yet, we never will.
      2. There’s not really a reason to hope for cost reduction of reactor construction once we do it at scale, because requirements and local acceptance are too heterogeneous to implement any sort of scaling construction. Every jurisdiction will have its own risk assessment and usually the locals are none too happy about a reactor close to them. I just don’t see something happening in that regard. Wind turbines and solar panels on the other hand can be churned out in factories at scale, which is why they’re so cheap, comparatively.
      3. Therefore, personally I’d rather invest in green H2 as an energy storage solution. We can easily generate an enormous electricity surplus during the summer months, but lack long-term storage of the electricity. So we shut off solar and wind farms when they’re over producing. Wouldn’t it be neat to instead let them keep generating and use that surplus energy to power power-to-gas plants E. G. with H2? It’s an enormously power-hungry process, but if you do it when power is basically free…

      Oh wait, we’re already doing that and it’s already cost-effective. Now, if we were to take that process and build it at scale… for example by not spending 12-20 Bn 💶 to build another Flamanville, Olkiluoto or Hinkley Point C… I think that might actually work.

  • Bill Clinton used to do this. Set goals and agreements that were like 30 years away. He did this alot. This is not new and is basically a way to look like you are doing something, but you and your administration would be long gone before there can be any accountability.

      Every place has a place to store it. It’s pretty safe and easy to store and does not need to be significantly contained for that long of a period. It’s relatively safe. “Real” green energy also produces a lot of waste and dangerous byproducts that “need to be” (read, should but often not) contained. Do you think solar panels grow on trees? No, the resources need to be mines and refined.

      • Besides, solar photocells have a limited lifetime. Recycling them is possible but expensive so people just make new ones instead. Kind of like plastics if you think about it.

    • Anyone with basic knowledge about anything knows that diversification is generally a good thing, this applies to energy as well: you don’t command the wind/sun and large scale electricity storage is to this day an unsolved problem. For all the big plans we have about a greener and carbon limited future, we need large amounts of dependable cheap and low-carbon energy, nuclear very much fits the bill (in complement to the other low-carbon energies).

        Large scale electricity storage is very much a solved problem actually. Bath county for instance has solved the problem since the 80’s.

        It’s just once you take the cost of storage for solar it is no longer the cheapest power source. Our power isn’t delivered by our government for the sake of sustainability and benefiting the citizens but by private corporations who want to make profit.

        The pumped hydro station I linked cost 4.36 billion USD to construct in 2022 dollars back in 1985. It also has a capacity of 24,000 mWh.

        Meanwhile the F-35 project cost the US government 1.7 trillion dollars.

        So let’s say new pumped hydro plants of a similar size would cost 10 billion dollars just for being excessive. Then let’s say the US government didn’t fund one jet and instead built pumped hydro storage. Then fuck it, let’s say nothing worked out the budget got blown and only a fraction of that were built so only 100 stations were built to make it a nice round number.

        That’s 2,400 gWh

        Idk about you but that is a lot of buffer to make any renewable much more stable. It’s actually enough buffer to power the entire country for a few hours and ideally bridge most of the night demand. For more than three times over budget and for the price of one jet for the US military.

        It’s also worth noting this helps all power generation not just renewables. All power plants prefer to be kept at their most efficient output and not turn off or cool off at night while demand is low. We really just need to have a buffer for when solar isn’t active but people are in the early mornings and late evenings.

        • Large scale electricity storage is very much a solved problem actually.

          I don’t want to sound pedantic, but how exactly do you believe pumped storage work? It’s not that complicated: you have a dam, i.e. renewable hydro, and when you get excess electricity from elsewhere, some of the water downstream is pumped back upstream so the dam can do its thing once again. Essentially, developing hydro storage means developing hydroelectricity and dams, but if hydro’s contribution to the grid hasn’t increased much in a very long time, it’s not because of conspiracies, but simply because most of the available capacity has been tapped already: https://en.wikipedia.org/wiki/Hydroelectric_power_in_the_United_States

          So, back to our initial problem: chemical storage (batteries) is expensive, environmentally dubious, problematic in many aspects and inefficient, chemical conversion (e.g. hydrolysis) is wasteful/inefficient, etc. So, no, we have no good answer to that.

            You’re not being pedantic, you’re just misunderstanding. Pumped hydro storage is not a dam, it’s not a power source, it is a power storage system. You can use pumped hydro at dams but basically anywhere you can move weight up high and use gravity to recoup that is a form of storage. It is one of the most efficient ways to store electrical energy with electric pumps and turbines. The point of a dam has been to collect water that is deposited there via rain and use that to create power.

            So, back to our initial problem: chemical storage (batteries) is expensive, environmentally dubious, problematic in many aspects and inefficient, chemical conversion (e.g. hydrolysis) is wasteful/inefficient, etc. So, no, we have no good answer to that.

            80% of this is just flat wrong. Chemical storage are not expensive at scale, enviromentally safe, not really problematic, and so outrageously efficient basically nothing comes close. Hydrolysis is more of a chemical reaction in organics and creating green hydrogen is done through electrolysis. It’s not wasteful or inefficient IF all of the power was surplus you had to get rid of because solar does that a lot. By your own statement solar panels are wasteful and inefficient because they only have efficiencies of what 22%?

            • Pumped hydro storage is not a dam, it’s not a power source, it is a power storage system.

              In technical terms, could you lay out what’s the difference? You’ve got a water retention system that empties into a generator and a capability to pump some of the water back upstream. What larger storages and generators do we have besides dams? None, and there’s no topographic feature that could be at an advantage there. Because the problem at hand is one of scale: https://ourworldindata.org/grapher/electricity-prod-source-stacked?country=~USA

              Assuming that energy demand remains the same (instead of increasing, which we know will be the case with more electrification), and that, to keep targetting those 4000TWh produced, we replace coal and gas by wind and solar. That would mean having to store what amounts to 2000TWh of production (under an extremely optimistic assumption of 80% storage capacity for the replaced energy only). That would mean that, just to buffer out what solar+wind require in storage, we would have to surpass what current hydro produces, 8 times over.

              I know this isn’t accurate (storage ≠ production, grid can be balanced out geographically, etc), but we are one order of magnitude in trouble already.

                There is no upstream, you’re thinking it’s a dam but you don’t dam up a stream. You have two containers at different elevations to store potential energy.

                You’re conflating a lot of things in this second paragraph. The world can generate enough solar for the entire planet off an area the size of new mexico. LA can power itself off just covering parking lots toe power itself. Then there’s nuclear, wind, tidal… All of these need a buffer because they struggle with either inconsistent production or inconsistent demand. Pumped hydro’s only purpose is to be that buffer. When you’re making lots of electricity you move mass up and when you’re needing more than you can produce you move mass down.

                The US can power itself for the next 100 year off waste nuclear weapons alone… but nuclear wants to sit at a flat load. Because of this, you’d need brownouts to shed demand. Pumped hydro means you can run more nuclear and generate more electricity than the grid needs at night or whatever and pump water up a tube to another container.

                Basically, the reason we use natural gas to generate power is because it is cheaper than anything and can be stopped/started with much less fuss. LNG tanks are pretty cheap, it comes from the ground at a determined rate… it’s super convenient.

                But a LiFePo battery system with inverters and solar is enough to power households if done efficiently for less than $50,000. The price gets lower every year and eventually people will be able to opt out of the grid entirely.

                • I mean, you don’t answer the billion dollar question here. Let’s not call it a dam, but a container, and let’s not mention the need to pump anything. The amount of (potential) energy you can store is a function of the volume of the above container, isn’t it? Then, could you estimate the amount of water this container would need to be able to retain in a scenario where the grid relies primarily on intermittent energy sources? And can you propose an engineering solution to contain this much amount of water?

                  The intuition here is that you are re-inventing dams, without the room to build more.

                  I don’t agree nor disagree with the rest of what you say, I just can’t get beyond the “energy storage is a solved problem” point yet.
