From the article: The provisional political agreement, which was reached after nightlong negotiations between the EU parliament and states, seeks to raise the share of renewable energy to 42.5 percent, from 22 percent today.

The EU has set an ambitious target to become a "climate neutral" economy by 2050, with net-zero greenhouse gas emissions.

The move also comes as the EU has sought to slash its dependence on Russian fossil fuels after Moscow cut gas supplies last year and the bloc placed bans on seaborne crude and other petroleum products from the country.

The figure is a compromise between the 45 percent share for renewables that was sought by EU lawmakers and the European Commission, the EU's executive branch, and the 40 percent preferred by the states.

The previous target for 2030 had been set at 32 percent.

The proposed directive seeks cutting red tape for renewable energy projects.

The goal is to "fast-track the deployment of renewable energies" as part of the EU's plan "to become independent from Russian fossil fuels, after Russia's invasion of Ukraine", said a statement from the Council of the EU which represents the bloc's governments.

Companies have complained that red tape has slowed the development of such infrastructure.

Good intentions and all, but implementation won't be easy. Everything right now has really long lead times, we are 12-18 month lead times now, vs. 6 months two years ago. BTW, nuclear is not included in this as it's not considered a renewable energy source.

The biggest changes in gas supply have come from the US and Norway, but the EU is also striking agreements with a diverse list of partners. Additionally, increased pace of renewables installation and reducing demand for power are playing a substantial role. Gas usage in the EU dropped significantly in the EU last year and that drop is likely to continue into this year.

There is so much to say about improving processess, eliminating tasks and paperwork

the case with nuclears isn't that straight forward since they belong to a different risk level category, if you messed up a wind farm its not bigger than common indstrial sites, usually lower than many standard cases, from land adquisition to materials to risk assessment so standard cases could be used as template to save time and then find ways to improving work flow and simplifying /standarizing to apply it to all member states regulations

for ovbious reasons with nuclear you need to be more careful about location needs, materials quality and building methods, security, safety, handling and disposal.....no cutting corners

Nuclear wouldn't even be able to provide global baseload capacity, while renewables can easily be scaled to provide for total global capacity. They are basically the only other source that could.

And it's so "safe" that the sector basically wouldn't exist without special legal constructs [see Price-Anderson in the US for exmaple) that absolve the industry from any responsibility regarding these "non-existent" risks:

>The Price-Anderson Act, which limits utility liability in the event of nuclear accidents, is totally out of sync with US energy goals because it places a heavy thumb on the scale of resource acquisition, favoring the wrong type of assets (high risk, high cost) in the current economic environment. In an uncertain environment, financial risk analysis teaches that the investor should preserve options and value flexibility by keeping decisions small and preferring investments with low, more predictable risks and short lead times. With their high risks, large sunk costs, long lead times, and extremely long asset lives, nuclear reactors are the worst type of assets to acquire at present.

A review of 97 papers published since 2004 and focusing on islands concluded that across the studies 100% renewable energy was found to be "technically feasible and economically viable."

It's scary when we look at the primary energy issue, compared with the renewable portion.

The good news is that it isn't as bad as it looks as that primary energy also includes the energy that goes to waste in creating it. All that waste heat leaving engines and smokestacks is a high portion of that primary energy.

netz_pirat t1_jeb3wk2 wrote

Yes, basically that. If you cover most of your energy needs with nuclear, switching to renewables isn't really a win in terms of co2.

If it's the best strategy going forward remains to be seen, replacing the aging fleet of reactors at an economical reasonable prices will be a monumental task, and the situation with the lack of cooling water in summer won't get easier either.

Nuclear isn’t the one solves all solution either. You’re still looking at heat release as surplus thermal energy because a nuclear reactor isn’t better than a coal plant when it comes to degree of efficiency (around ~30%). Only with renewables that won’t happen because the energy in nature would end up as heat anyway because it’s already in the climate system, wether you use it or not.
This should be taken into account when scaling up.

Nuclear power will also stop working as the planet warms, because the temp difference in the water source you are using to cool the plant will not be enough to keep the plant running. This already happens in some southern nuclear power plants in the US.

Can't cool your reactor if your "coolant" water comes in too hot.

On a global scale, so far:
So far, the AHF has no relevant climate impact on a global scale. However, given continued growth in a decarbonised world, the AHF can become a relevant factor of post-greenhouse gas warming in the relatively near future within the next century. Also, on a local scale, even today the AHF is a non- negligible process. This holds not only for the direct AHF impact in urbanised areas, but also for remote, large-scale areas like the sea ice near Greenland due to the ice-albedo feedback and impacts on the ocean circulation. The analysis of CLIMBER-3α has shown that a forcing as small as the AHF in the current years (roughly 2% of the CO2 forcing) can influence ocean circulation in such a way that a temperature change of more than ±0.3 K can result in the Arctic region with significant changes in the sea ice cover.

That is not what the article actually claims though:

>Historical observations show a constant exponential growth of worldwide energy production. A continuation of this trend might be fueled or even amplified by the exploration of new carbon-free energy sources like fusion power.

The problem isn't "fusion", the problem is the exponential growth in energy production which leads to AHF. This is an inherent issue if you use heat engines to generate electricity - which both fission and fusion do. Nuclear power plants have a thermal efficiency ~33%:

https://www.nuclear-power.com/nuclear-engineering/thermodynamics/laws-of-thermodynamics/thermal-efficiency/thermal-efficiency-of-nuclear-power-plants/

while combined cycle gas powerplants can reach about twice of that.

This would be an issue with fission as well as with fusion. Seeing how you can scale neither fission nor fusion to even meet global base load demands that issue is mainly theoretical though. Basically all forms of nuclear power run into massive issues when you try to scale them beyond 1 TW globally.

I'm pointing you to real time data from right now, where nuclear produces dozens of actual gigawatt of carbon-free power and wind+solar sucks and fails to meet demand that has to be covered by gas and coal, but hey, don't let facts get in the way of your pie in the sky schemes where solar makes sense in Northern Europe and anticyclonic events don't affect the whole continent.

Also re levelized cost of electricity, do you know what the lowest sell PRICE of that wonderful Danish wind power is on the market? It's almost 0€. Not because it's cheap, but because it's next to worthless when there's plenty of wind as there's too much supply and nothing to do with it. And you know what the Danes have to do when there's no wind? They have to buy hydro from Norway at outrageous prices, because there's huge demand.

My point? The levelized cost of intermittent renewables WITHOUT pricing in storage or alternatives is just a fucking lie. Nuclear does the job, it's doing the job right now.

There's about 100 GW of already installed capacity. That's 100 GW more capacity on windless winter days than non-hydro renewables.

However, generation from natural gas was 1.7% higher than in 2021, generation from lignite increased by 5.4% and generation from hard coal increased by 21.4%. This is due to the fact that Germany allowed coal-fired power plants to return to the electricity market to be less dependent on natural gas amid strained relations with Russia.

If many of these points were true it would also make renewable energy transition impossible. New sources of uranium and minerals(such as rare earths needed by renewables) are made avalaible if the price increases.

Also this point just wrong.

>for 300,000 years. However, Abbott argues that these reactors’ complexity and cost makes them uncompetitive.) Moreover, as uranium is extracted, the uranium concentration of seawater decreases, so that greater and greater quantities of water are needed to be processed in order to extract the same amount of uranium. Abbott calculates that the volume of seawater that would need to be processed would become economically impractical in much less than 30 years

Extractring it from seawater isn't economically feasible, expect it is because it is because it can become economically unfeasible, after we exctract just 0.01% of the uranium from the seas, which in turn doesn't make any sense. How would such tiny a reduction in consetration would make process unfeasible? Not to mention that new uranium is dissolved in the seawater if concetration decreases.

I agree with you that going 100 % nuclear doesn't make sence, but quality of that study highly questionable.

"Legal" requirement sounds like you don't really care if you'd kill thousands if not millions of fish by giving them a heat stroke.

Power plants need to cool down their hot cooling water to harmless levels before releasing it back into the lakes or rivers. That is what those giant cooling towers are for. But on hot summer days, their efficiency is greatly reduced and that limits the plant's thermal waste output and thus production capacity. And that is why they should be paired with solar energy to fill the gap on such hot days.

Sure, but you really need to get the electricity generation to a certain level of Low CO2 production before the electrification of other industries. It's a multiplier. Just like electricity generation, the economics of switching these other industries has recently (or currently is) at the tipping point, where it makes financial (or Security) sense to switch.

People will be surprised how fast these other industries transform. Jut like they are today with electricity generation

Given that this law has been repealed this summer during the worst drought of recent history without any consequences, it's fair to say this piece of legislation was unnecessarily cautious.

In any cases that's not related to what OP said about water being too hot to cool down the reactors, with a lot of confidence.

Sol3dweller t1_jedtmq0 wrote

edit: nevermind, I figured now it is talking about total energy consumption, not just electricity. It's just a coincidence that the 22% matches up with wind+solar for electricity.

It's a little bit confusing, as renewables generally includes hydro and biomass. While the cited numbers are rather only wind+solar. If you include the others, renewables had a share of 38.6% in 2022 in the EU. 22% are just wind+solar, so I think that this article solely refers to those and their doubling.

The EU increased its solar share from 3.33% in 2014 to 7.27% in 2022 in the course of eight years. And it's wind share from 7.86% to 15.01%. So, a doubling over the next eight years is essentially just a continued exponential projection of the trend so far.

Which shows how unambitious the previous goal was. Now with the expectation of rising electricity demand, due to electrification of other sectors, this increase in share amounts to more absolute increases, but still, it appears like a fairly realistic target.

As your cited study points out. This heavily depends on where you place the solar panels. You can easily imagine that things like black-tiled rooftops or asphalted parking lots are actually improved in terms of absorbed heat by covering them with solar panels.

The issue is that the concentration in seawater is measured in ppb to begin with and the amount of water you need to filter to extract meaningful quantities of Uranium rises to infinity as the Uranium is extracted.

>This tells us that, for example, in as little as T = 30 years, a volume of seawater of 7x10^15 m3 would need to be processed - this is clearly impractical as it is over six times larger than the volume of total river outflow in the same time.

Nuclear is already the most expensive option out there. It simply isn't viable as a replacement for fossil fuels on a global scale, and given the growth in energy consumption it is bascially impossible to scale it to meet global base load demands.

This is satire, right?

Russia is the perfect example for your policy recommendation: no renewables, but doubled the nuclear power output since 1998.

Here is how the share of low-carbon electricity developed respectively over the past 20 years. In the EU it increased from 48.2% to 60.5%, while in Russia it increased from 34.4% to 40%. In relative terms that's a growth of 16.3% in low-carbon share in Russia, and a 25.6% growth in the EU.

Consumption of gas for primary energy peaked in the EU in 2010 before Fukushima at 4,228 TWh. It's use declined over the past decade to 3,966 TWh in 2021.

The EU decreased its nuclear power output since 2010, Russia increased it (in terms of primary energy from 454 TWh in 2010 to 558 TWh in 2021). But Russia also increased its gas consumption from 4,239 TWh in 2010 to 4746 TWh in 2021.

So you have: Russia implementing your policy advice, expanding nuclear power and shunning solar+wind, and the EU decreasing nuclear power output and expanding solar+wind. But these examples do not seem to support your conclusion. Rather the other way around, the example with increased nuclear power output also increased gas consumption, while the one with increased solar+wind decreased it.

Renewables are a shock to the fossil fuel providers, as they are eating into their market shares. Not only in the EU, but on a global scale: in 2011 fossil fuels constituted 86.16% of primary energy consumption globally, ten years later this share wass decreased to 82.28% in 2021.

This article discusses this aspect more specifically for Russia:

>Russia is the world’s top exporter of both oil and gas, and the third largest oil producer making it a major extraction powerhouse. According to data from the International Energy Agency (IEA) revenues from oil and gas-related taxes and export tariffs accounted for 45% of Russia’s federal budget in January 2022. > >This makes its economy uniquely vulnerable to the impact of disruptions, and suggested that in order to assert itself in a context of looming economic decline, it may resort to increasing aggression (both internal and external). Once Russia’s oligarchy saw peak oil demand in the rear view mirror, it would get increasingly aggressive and aim to maximize short-term extraction and cash flow. Given Russia’s preeminent position in the fossil fuel system, its recent expansionist history, and the likelihood of oil prices crashing down to the $20/barrel level by the end of the 2020s (which Seba predicted in Clean Disruption), Seba assessed that it was one of the top candidates for increasing geopolitical instability.

So you have declining fossil fuel consumption in the EU since 2006 (decreased from 15,103 TWh to 11,759 TWh in 2021), and increasing renewable power output. And you conclusion from that is that the renewable power is a boon to the fossil fuel providers?

If you would reduce consentration by 0.01 % (30 years/ 300000 years) you would need to process 7,60076 x 10^6 m3/s of seawater after 30 years. Not 7x10^15 as the study claims. The calculations just doesn't make any sense. The equation doesn't take properly to account the total amount of seawater in the oceans.

>Nuclear is already the most expensive option out there. It simply isn't viable as a replacement for fossil fuels on a global scale, and given the growth in energy consumption it is bascially impossible to scale it to meet global base load demands.

I didn't say anything about the feasibility of using nuclear to replace all fossil fuels, so please do not argue against this strawman.

Your example is irrelevant since France already has lower targets. And yet, Germany has progressed more as opposed to France in % reduction.

COP target Germany: cut 65% emissions from 1990 emission level. Current emissions from 1050 to 675 million tonnes. Reduction = 36%

COP target France: cut 40% emissions from 1990 emission level. Current emissions from 400 to 300 million tonnes. Reduction = 25%.

Not only is France behind in the progress to meet targets, the emissions in absolute numbers are way less too.

Natural gas is highly dispatchable which is probably why Germany went high renewable and high natural gas. Sun stops shining turn on natural gas.

But it's just a symbiotic relationship that will end eventually. Batteries are becoming cheaper intra-day options.

We are going to be testing higher and higher limits of how much of the super cheap solar and wind can be on the grid and then fill in with dispatchable gaps which can be filled in by hydro, natural gas, biomass, batteries or firm which is nuclear, geothermal, coal. Reducing the higher CO2 options.

Primary energy is mostly waste heat. Using it massively overstates its importance. Electrification usually cuts energy use by 1/2 to 2/3. Once you allow for that, you find we're much closer to net zero than you would expect.

​But the article I brought up did. The claim being made isn't that nuclear needs non-renewable "minerals" while renewables don't. The issue is that "minerals" used in renewables are actually recoverable because they aren't irradiated.

Please actually read and at least try to comprehend the paper:

>This tells us that, for example, in as little as T ¼ 30 years, a volume of seawater of 7x10^15 m3 would need to be processed - this is clearly impractical as it is over six times larger than the volume of total river outflow in the same time.

This is the total volume of water that needs to be processed at that point, not volume per second. As stated, this would be six times the volume river global river input would be able to provide in the same timeframe, meaning this would be inherently unsustainable.

"Seawater" contains ~3 ppb Uranium, i.e. 3/1000000000, i.e. 0.0000003% of which 0.7% are actually fissile. Your initial concentration isn't 100%, it's 0.0000000021 %.

If we assume that 1 l of seawater has an approx mass of 1 kg (seawater is actually denser but let's ignore that) and assuming that the process was 100% efficient in recovering all the fissile Uranium (it wouldn't be, but let's also ignore that), filtering 7.6*10^6 m³/s of seawater would yield

7.6*10^9 kg/s * 0.0000000021% = 0.1596 kg

The energy contained in 1 kg of U235 (if the conversion was 100% efficient which is isn't but let's ignore that) is 83.15 TJ - ergo the energy you could extract from 0.1596 kg is 13.27074 TJ or ~1.33*10^13 J. Let's just ignore that the thermal efficiency of nuclear plants is ~33% to begin with.

Extraction probably requires pumping all that seawater through a filtration plant, chemical treatment, whatever. Let's assume that all we have is water and U235 - no additional impurities, no uranium compounds that need to be purified and extracted etc. Let's assume we could simply separate water and uranium via reverse osmosis and ignore all the additional steps and energy that would actually be required to use it in a nuclear reactor.

Filtration via reverse osmosis of 1 m³ of water requires 3 - 5.5 kWh. Let's be optimistic and go with 3 kWh/m³ - that's 10800000 J/m³.

Ergo we would need 8.21*10^13 J to filter all of that U235 from the 7600000 m³ we need to process.

Or in other words, extracting uranium from sea water has a negative energy yield, even if we assume that we could somehow seperate it via simple reverse osmosis and the energy conversion was 100% efficient. Which it is not.

>I didn't say anything about the feasibility of using nuclear to replace all fossil fuels, so please do not argue against this strawman.

Even providing global base load would not be feasible let alone economically viable or possible on any meaningful timescale. Given that nuclear isn't a solution for anything, not actually needed and provides no meaningful benefit, what exactely is the point of wasting money and resources on this?

There is a reason why nuclear has been stagnating for the last decades and will play an ever diminishing role in the coming decades:

Nuclear is a dead-end for terrestial utility scale power generation. Renewables are the only feasible way to decarbonize our energy sector.
