title: simsa03: What I don't understand about the rush to SMR nuclear reactors: Why not adopt already existing naval nuclear reactors and their designs? Is it that they use up to 90% enriched fission material whereas civilian reactors only use 5% to 20%? So, although naval reactors use weapons-grade nuclear material, they come with the advantage that they can be shut down and powered up in seconds which could make them appropriate to balance the volatility of renewables in the grid. #nuclear #renewables #peakrenewables #energy #infrastructure

But for the utilities forcasts are difficult to make because • data center customers have placed simultanous orders with different utilities in the same area • the Trump tariffs make construction costs of new facilities unpredictable • it is unclear how electricity consumptive AI is really going to get. Thus building too little capacity may risk brownouts (not "blackouts" as the article states) while building too much may increase prices for consumers and housholds. #peakrenewables #energy

Its size is expected to reach $67bn by 2030, according to estimates by consultancy Rystad Energy. Utilities wanting to buy the key piece of electrical infrastructure would now have to wait three to four years if they have not reserved one already, said Schierenbeck, formerly CEO of German energy company Uniper. The supply chain bottleneck is another pinch point for power systems struggling with surging growth in electricity generation and ageing infrastructure. In particular, the expanding share of renewables in the electricity mix in some markets requires more transmission equipment because they are often located far from users and produce power from more dispersed sources than traditional electricity plants. That has created an urgent need to upgrade the grid to tackle huge waiting lists for new projects to connect to networks, as regulators struggle to cope with the major power system overhaul that decarbonising requires. » #energy #infrastructure #renewables #peakrenewables

title: simsa03: I don't think that it is possible to neatly separate the home user market for electricity from an industry market one. The more #renewables you connect with the grid, the more traditional power plants you need to avoid net fluctuations. That is: All home users with their IMO naïve idea of "selling back to the grid" ignore that their fantasies presuppose the full-fledged operation and round-the-clock availibility of what they want to abolish: Traditional powerplants (coal, gas, nuclear) in massive sizes, ready to step in any minute. There is, again IMO, no way that renewables can be used meaningfully on a private home-owner basis. Whih is one of the reasons why I think #peakrenewables is far more realistic than some "green electricity" future.

title: simsa03: Well, yes and no. You mentioned storage, then flipped to production. Renewables have no capacities for storage. And their electrcity generation is imbedded in a context of other factors like grid stability, prices at spot markets, etc. The commingling of topics was in your notice, not in mine Turning "production processes to electric" is a pipe dream. The transformation of the chemical industry in DE alone would require us to put 500 TWh/a annually on top of the current annual consumption of 600 TWh of electricity, and that's only the chemical industry. And no, you cannot create that electricity to prices that keeps chemical production and products competitive. And a further no, as we didn't even mention how ore mining and refinement of minerals to produce the renewable stuff relies on fossil fuels in the mining industry and thus ads to fossil fuel consumption as to climate emissions. Accorting to a McKinsey report (need to look up the link), the transformation towards electricity across all sectors till 2045 would require DE alone to pay about € 10 trillion total, that is € 500 billion annually. Nobody has that money. I could open a different thread on why I see #peakrenewables but I leave that for another day. One example may suffice: We'll be lucky if in DE alone we can keep the power output of wind on-shore at current levels given the decommissioning of about half of the fleet from 2026 onwards due to end of life requirements. We're talking about 14,000 units that need to be replace *before* we can add more electricity generated from wind on-shore. And yes, stuff like Tesla's Megapack seems feasible in decentralized, movable logistics environments as that of the military in war zones. Another field may be development aid and disaster mitigation. But here the consumption is relatively small and by no means on a scale that could serve as a base for industry-size production.

title: simsa03: Partly so, in my opinion. I concur with the assessment that dezentralised energy storage capacities will – over a long strech of time – mostly benefit the military and its increasingly electricty-intensive equipment (drones, flight control, interception, AI managed swarms, etc.). But that does not pertain to volatile #renewables like wind and sun whose effectiveness and suitability far more depend on grid structures, base loads of consumption and conventinal production, electricity markets, network costs, etc. That's one of the reasons, BTW, why I speak of #peakrenewables: They can positively contribute up to 30% in the overall electricity production, marketing, transfer, and consumption – beyond that it mainly increases costs and creates negative price offsets. And storage even for such minor for such capacities is not on the horizon. Hydrogen production on site of renewables is laughable (10% effectivness) and hydrogen powered plants are, well, not in sight. Thus I think the current Tesla "Megapack" battery units (3.9 Mw/h storage per unit) is currently the best solution not for private, municipal, or commercial solutions but for military. [Sidenote: And given the demand for batteries, I find it plausible that the vast lithium reserves in the Donbas region provided one of the main reasons for Putin to invade Ukraine.]

title: simsa03: Sigh. Ok, you believe in renewables and their ability to not only provide the electricity for the current needs but for what is necessary in the decarbonisation of ultimately fossil fuel-run industries. You believe that we're not already *not* reaching #peakrenewables (e.g., all current installed wind turbines worldwide will have to be replaced by 2050) but you think that societies will even be capable of financing that transition. (A recent McKinsey report estimates that for Germany alone to transform all its energy needs throughout all sectors until 2045 roughly cost € 500 billion annually.) Somewhere down my bookmarks I have the numbers and estimates of the fossil fuel and carbon emissions needed to extract all the minerals the world would needs to build all the renewables and storage systems. I won't get into that discussion tonight, but I don't see *any* chance to attenuate the climate crisis by adding more of the same, even if it comes with catchy phrases like "circular economy". (And in all of that we haven't even touched the issue that progress in one sector is pretty much erased by inventions in another – see, e.g., how the rise of cryptocurrency mining has wiped out the emission reductions reached by 30 years of PV deployment, or the projected electricity consumption of AI that will turn the goals of decabonisation into a child's play.) "Circular economy" like "lesser material consumption for renewables" will turn out like "degrowth": Nice to have, but only possible on-top, and in that presupposing the full functioning of the system they intend to replace.

This constitutes a dramatic shift from the last 150 years when the thirst for fossil fuels persistently rose. But now this growth is nearing its end sooner than many expected, driven in part by a surge in renewables. This significant event, however, masks a more striking possible future: One in which total global energy use peaks and energy’s weight in world affairs diminishes. [...] In a broader sense, just as history has included the stone, bronze and iron ages, we have been living since the Industrial Revolution in an energy age. But this age, during which energy has dominated so many economic, geopolitical and other dimensions, may be coming to an end with peak energy.» A bit confusing is the author's talk of "energy peak" which seems to lumb together energy and electricity demands. Thus, whereas I can see a decline in energy demands, I don't see them with regard to electricity demands. (Esp. with all the decarbonisation of industries necessary to accomplish mitigation with climate change.) Anyway, an interesting piece with a lot of interesting links.

title: simsa03: Batteries are prone to ignite and incinerate. Are there any studies on the insurance risks of large scale storage batteries necessary for the back-up of renewable energy? As they so essential for grid stability, can they be insured at all? How does that impact electricity prices? #energy #infrastructure #renewables #peakrenewables #batteries

title: simsa03: Talking about "reducing the demand for FF" is ridiculous in at least four ways: a) It prevents states in Africa to jumpstart their economies to benefit their citizens with cheap energy systems (resources and power plants), and, via surplus value, become capable in the first place to invest in environmental protection. (Not to forget the #ecocolonialism involved in the vast green land grap in Africa.) b) It ignores the life cycle of #energy systems because even after a new source of energy has been found and disseminated, the older energy sources keep delivering and *increase* their output. It takes roughly 60 years for a new energy source to substitute and leave behind an older one. c) It ignores how much FF are involved in the production, the spread, and the integration of "renewable" energy systems in a given #infrastructure: From mining and processing of materials, to production and spreading of units, to the hitherto unsolved problems of recycling of these new systems (and thus "loss" of the engery invested in their production). d) Even in the sub-sector of electricity production, relying on #renewables means relying on fossil fuels (esp. when #nuclear power is abandoned). As demand increases, #peakrenewables is already in play, only sugarcoated by high subsidies. (Germany alone will have 14,000 wind turbine units of its 30,000 onshore units decommissoned after 2026. Germany will be lucky to keep the current electricity output of the wind turbine units; it rather becomes increasingly harder and less likely that more output will be generated in the future -- at least within a market economy.) The chatter about "reducing the demand" is the result of an individualist consumer approach, which suggests to cut back on holiday flights etc. With regard to infrastructures of whole societies, that is a mistaken approach.

title: simsa04: Jon Henley, "European countries pledge huge expansion of North Sea wind farms" https://www.theguardian.com/environment/2023/apr/24/european-countries-pledge-huge-expansion-of-north-sea-wind-farms «Aiming to both curb reliance on Russian gas and radically reduce the use of CO2-emitting fossil fuels, the nine countries aim to boost their combined North Sea offshore wind capacity to 120GW by 2030 and 300GW by 2050.» «Britain has 45 offshore wind farms producing 14GW, with plans to expand capacity to 50GW by 2030. Germany has 30 producing 8GW, followed by the Netherlands with 2.8GW and Denmark and Belgium, both with 2.3GW. France aims to expand massively to 40GW by 2050, an official said. They added: “Offshore wind energy will probably be the main source of renewable energy production between 2030 and 2050, far ahead of solar energy and land wind farms.” The investment required to ensure the North Sea wind energy targets are met is huge – the EU recently calculated €800bn would be needed to reach 300GW by 2050 – and wind energy companies have said significant state funding will be essential.
