Nah, that's wrong. Lignite mining in Germany is still on the decline, as it has been for last ~10 years. So is electricity generation from coal. Renewable generation has been growing rapidly over the last years, accounting for 46% of all generated Wh in 2019.


Nah, that's wrong. Germany is ahead of its set policy goals, even if you do the mental gymnastics of just not counting biomass as renewable.

First off, this is great info and changes a lot. That's not 'ahead' as I'd define it, that appears to be "meeting". Its worth noting the article highlights that its more likely they will meet it due to drops in transit emissions, not so much that they cut power emissions significantly enough to make the goal.

Second off: They still shouldn't have shuttered their nuclear plants versus continuing their use of gas and lignite/biomass. Biomass is not renewable, sorry. In a time when we need to cut every ounce of CO2 and Methane emitted, any sort of biomass is just a bait-and-switch.

Why is biomass not renewable? I can understand some complaints, such as how handling some types of waste biomass in some ways can generatre methane emissions and how larger trees take time to accumulate the biomass and thus not offsetting the carbon emitted by burning trees right now. But over time it is almost completely renewable and dedicated energy forestry have very short generation time of 3-7 years.

The issue is "what is biomass" because if you mean "biomass that's grown in a sustainable way that's not causing unsustainable land use change" then sure.

If you mean "Pretend its sustainable growth when it isn't, ship it from North America to Europe with fossil energy, then pretend that its carbon neutral to burn, and give bonus credits that make it effectively considered carbon negative by the emissions markets" then no:

quote:

https://www.vox.com/science-and-health/2019/3/4/18216045/renewable-energy-wood-pellets-biomass

Yet all this, scientist Bill Moomaw argues, comes down to a tragically shortsighted view of both carbon accounting and our current climate predicament.

Moomaw, now a professor emeritus at Tufts, is a co-author of the Nobel Peace Prize-winning Intergovernmental Panel on Climate Climate report, co-author of four additional IPCC reports, and an expert on carbon sinks.

In 2009, as Massachusetts began debating whether to treat biomass as carbon neutral, he dove into the science. By assessing carbon emissions from bioenergy, and the slow regrowth rates of a replacement forest, he concluded that biomass stood to be “a serious problem.” To Moomaw, the question of whether biomass was ultimately carbon neutral was less important than when it balanced out.

Along with Mary Booth, a colleague who brought the issue to his attention, Moomaw and the Conservation Law Foundation convinced state officials to limit subsidies for biomass under the state Renewable Portfolio Standard. Unfortunately, the state later allowed large subsidies for burning wood to heat buildings.

The analysis was later confirmed by a colleague at MIT, John Sterman, who did the math, and confirmed that burning wood today would worsen climate change, “at least through the year 2100 — even if wood displaces coal, the most carbon-intensive fuel.”

Moomaw was concerned. The science on biomass, unlike that on the influence of carbon dioxide on warming, isn’t totally settled. Both carbon dynamics and forest science are complex and contentious fields, and in assessing whether biomass is better than alternatives, models have to take into account — or deliberately elide — complex factors. The assumptions those models make around variables like how fast wood decays in various ecosystems, and how much carbon gets reabsorbed into the soil, determine what kind of impacts they find for biomass.

But from an environmental policy perspective, Moomaw said, none of that was the point, because one thing wasn’t up for debate: Burning biomass means quickly dumping more carbon into the atmosphere at exactly the point we need to begin rapidly drawing it down. “I’m at loss to understand how this [policy] went forward unless you discover there was total government capture by the forest products industry.”

The first problem, he argued, comes from the industry-promoted idea that biomass simply makes use of wood that would have decayed anyway, an assumption made by the European renewable energy standards. Under the terms of the Kyoto Protocol, the forest owner, not the end-user of wood products, is supposed to account for the carbon lost when a forest is cleared. Because the assumption is that the cleared trees would decompose anyway, companies like Drax only have to count the carbon needed to turn from waste wood into fuel — gasoline for chainsaws, diesel for shipping — not the actual carbon that leaves their smokestacks.

This means that wood bought from the US effectively disappears from carbon markets, if not the atmosphere. The US, thanks to George W. Bush and a late-game lobbying effort by the fossil fuel industry, isn’t part of the Kyoto agreement, which means that it is not bound to keep track of emissions from forest loss.

Also, “waste wood” being pulped for biomass is only waste because the market doesn’t properly value carbon. It’s possible to envision a world in which forest owners are paid for the service their growing trees provide in pulling down carbon. “If we let some of our forests grow, we could remove an additional 10 to 20 percent of what we emit every year,” Moomaw said. “Instead, we’re paying subsidies to have people cut them down, burning them in place of coal, and counting it as zero carbon.”

The second problem cuts to the heart of the concept of carbon neutrality, and therefore to a core miscalibration in our system of carbon accounting itself: time. Carbon emission standards were put in place, remember, because the world is in the early stages of a climate crisis likely to get much, much worse.

Another example is the Californian emissions market gives such a bonus to capturing methane without concern for what created it that it will keep a few coal mines operating because it turns a loss-making operation into a profitable one. So the coal mine gets money for capturing the methane they created mining coal. Company wins, climate loses.

Also one has to consider the reality that as we continue into the future forests are getting less healthy and they will store less carbon. This means that we can't really rely on future forests to credit our current emissions even if the legal schemes say we can.

This doesn't change much though. Because this doesn't actually match daily power usage. This just shows sources, not the flux daily that heavily favors gas/coal.

Your looking at the big picture and ignore the gaping holes that fossil fuels continue to fill that need to go away, and will not be filled by renewables or storage.

And no, you are ad homing, sorry dude. Calling it all Dunning Kruger and pretending that there isn't still an issue is a problem. Even your got damned graphs: Lignite, Coal, and Natural Gas are STILL significant energy factors that are not being replaced fast enough, because there's going to be a point of no return where they can't cover it during the day be it winter, lack of wind, or not a peak solar period, and energy storage density is NOT there.

Nuclear power is a relevant contemporary topic in energy generation. It might be very clear that new nuclear build will not be the easiest path to a zero carbon energy sector, in that it's very much an ongoing concern whether or not to retire the aging nuclear fleet or to phase it out in favor of other sources. Those plants can't run forever, but every sizable piece of zero-carbon generation is worthwhile. Existing nuclear is becoming uneconomic to dispatch compared to renewables and especially due to lowered natural gas prices, but it's a huge lost opportunity if nuclear plants are retiring while coal plants are still limping along thanks to regulatory and legislative fuckery.

Exactly. The basic agreement with the Energy Generation thread is: Renwables are Good. Nuclear is good. Fossil fuels of any sort is bad.

The problem is the basic load that fossil fuels provide is difficult to replace with renewable and will likely keep limping along no matter how much Renewable we put on the grid, we need a way to eliminate that fossil base. That's what nuclear is for.

That's not a chud opinion. A loving Chud would be screaming about saving coal/oil jobs, not promoting an energy source in combination with renewables that will ENTIRELY wipe out out the need for fossil fuels, and combined with the electrification of Transit, which is a must, we're going to need HUNDREDS if not thousands of GW to spare for charging cars, buses, and maybe even ships (if we don't get a nuclear merchant marine going, which probably won't happen).

Ending our fossil energy glut isn't the last step, because if we want to turn this Climate bus around, we have to end it all, and we have to have the electricity to spare in off-peak hours that grid storage is not going to provide.

Its not just about replacing Fossil fuels, we have to generate more energy without adding to our emissions debt. There is no other energy source denser that nuclear, period.

Charging transit: you can setup buffer batteries to take care of peaks - also time charging so that you do the bulk of charging at night, and top up batteries when there's excess renewable production.

Ships: We're already operating electrical ferries in Norway, but that's a fairly limited use case, with very frequent charging. We'll probably see a shift towards more (sustainable, maybe?) biofuels and possibly also hybrid sailing vessels to decrease fuel usage. I'm not sure I'd want a nuclear reactor on a civilian freight vessel, I've met my fair share of engineers in the merchant marine who shouldn't be let anywhere near machinery of any kind :smith:

Nuclear is definitely part of the energy mix of the future, even though there's a bunch of under-educated/misinformed idiots out there, especially politicians, who try to sabotage nuclear at every step. To our common detriment...

Germany was mentioned earlier in the thread. They'd be further along if they weren't shuttering their nuclear plants, although they still have a fair amount of generating capacity left.

The problem you have here is: Imagine replacing every car on earth with an electric car. Every single one. Think about the sheer amount of trillions of joules of fossil fuels you have to replace. Its not a storage issue. Its a need for more energy that's not fossil fuels.

UK has already established 2035 for cutoff of sales of petrol and diesel cars (we'll see if they stick to it, I hope they do). That's 15 years we have to figure out how to provide the same amount of joules as all the petroleum we have to stop using.

We use 98.8 billions of barrels a day, and even if we don't account for other uses like agriculture, plastics, etc, each barrel is 6.118e+9 Joulse of energy. That's a LOT of energy we have to generate without fossil fuels.

Yeah, transit isn't much of a problem. IRC current consensus is that we would need around 10-20% more electricity generation per year for complete electrification of all cars in Germany. That's roughly in the same ballpark as what we are already exporting to other countries each year due to lack of demand.

Yeah, here is a collection of counter points from the federal government to the usual right wing/chud arguments against personal transport electrification

https://www.bmu.de/fileadmin/Daten_BMU/Download_PDF/Verkehr/emob_strom_ressourcen_bf.pdf

quote:

Eine vollständig elektrifizierte deutsche Pkw-Flotte von 45 Millionen Fahrzeugen hätte einen Strombe-darf von rund 90 Terawattstunden (TWh). Dies entspricht weniger als einem Sechstel der aktuellen Bruttostromerzeugung in Deutschland. Der Anteil der Stromerzeugung aus erneuerbaren Energien be-trägt aktuell bereits rund ein Drittel. Die 2015 erzeugte EE-Strommenge von 196 TWh ist also doppelt so hoch wie der Bedarf einer komplett elektrischen Fahrzeugflotte.

Some quick sanity check/napkin math make the claim seem plausible:

There are ~47 mio cars in Germany. Average driven distance is ~15000km p.a., average energy use of an electric car is 15kWh/100km. That makes a total energy demand of ~106 TWh p.a. or roughly ~17% of total generated Wh in 2019.

did you not see the big giant charts on your screen?

the first one clearly answers your question about carbon neutrality. (the answer is no, of course not, no one is even close to that, regardless of nukes, not even france)

the second one shows the math to answer the second half of your question. Since "Energiewende" began (2013) nuclear production has been reduced about 20TWh/year while coal went down ~85 TWh/year.

Over that same time period wind and solar increased about 90TWh/year. Essentially wind and solar replaced coal 1:1 while nuclear just got retired slowly.

It is only a relentless prioritizing of being a technically correct contrarian concern troll that keeps people talking about nukes. In actual realty (see graphs) the german energy transition is going far far better than almost anywhere else in the world, and we should be praising them and emulating them not tut-tuting our amateur horseshit about nukes.

This is analogous to concern trolling about long waiting times or various other nitpicks of the canadian or british healthcare system when people are promoting medicare for all. You're not helping, you're not even really correct, you're just babbling contrarian nonsense in service of undermining consensus and progress in order to defend the status quo.

Your selected timeframe is omitting the bit from 2006-2012 where there was a 60 TWh reduction of nuclear generation while coal was treading water (hard coal down a bit, lignite up a bit). Also, during this 2013-present timerame the chart also shows about a 30 TWh increase in gas-fired generation. This might be good enough to meet current emissions targets, but it remains to be seen that reaching longer-term decarbonization is possible with a mere extension of the current trend of replacing things with wind, solar and storage (even if biomass is technically renewable I think there are a lot of use cases where it's far from carbon-neutral). Once the percentage of wind/solar gets high enough, managing the grid becomes harder due to curtailments, so having dispatchable zero-carbon resources remains important.

I would say that there's limited utility relitigating the past, but you should not be surprised that people are refusing to view Germany's policy solely through the lens of 2013-2019. Also, given the scope of the climate crisis any increase in burning natural gas is a Problem.

Now if those nuclear retirements were truly reflecting the full lifecycle of those plants, it doesn't reflect much of an opportunity cost, but if things are similar to the US where nuclear retirements are primarily due to economic concerns, then that's another story.

The same for gas and nuclear.

Germany has also been importing more power last year because it was cheaper.

Yeah haven't they been a net importer for ages?

They've exported more in the 5 previous year mainly because renewables produced too much and they didn't want to tank the local prices.
Headlines were that on some days all of power consumption was covered by renewables (It didn't say how much of the day, though).
This highlights that energy storage is important for renewables, even with conversion losses.

If you removal the Soviet submarines, Nuclear merchant ships had a good track record.
I mean for the whole 2 (outside of Russian Icebreakers) that were built.

You mean the American one that was so expensive to operate it only was in service for 10 years, the German one that was so expensive to operate that they re-engined her with a diesel, or the Japanese one that leaked a trivial and utterly insignificant amount of radiation and wound up having ports blockaded against her entrance by angry fishermen?

Considering the Japanese design, like Fukushima, was against the advice of other reactor designers, and we've come a long way since then, I suspect modern reactors would likely not have these same issues.

quote:

As the crew brought the reactor up to 1.4% of capacity at 5pm on 1 September 1974,[6] there was a minor shielding inadequacy that permitted the escape of neutrons and gamma rays[4] from the reactor shielding enclosure.[6] Westinghouse Electric Corporation had reviewed the design and warned of this possibility, but no changes were made to the design.

And considering where we're going with SMRs, this makes it incredibly easy to integrate a stable reactor design into ship design.

Again, I said its incredibly unlikely to happen, but it would solve a lot of emissions issues.

The biggest container ships built so far has a 11 cylinder diesel engine, weighing in at 2 200 tonnes and outputs about 75MW peak. Those ships weigh in at over 228 000 gross tonnes, so a few hundred tonnes give or take in the engineering spaces hardly matter much.

To give an example, the reactor compartment on the USN nuclear cruisers (page 57) weighed in at 1400 tonnes with two D2G reactors, though power output is significantly lower (at 45 MW to the shafts). That's a fairly old military design, though.

I doubt it would be extremely hard to build one of those container ships with a nuclear power plant, but steam-operated ships are passé, so that's a hurdle to pass as well.

did you not see the big giant charts on your screen?

the first one clearly answers your question about carbon neutrality. (the answer is no, of course not, no one is even close to that, regardless of nukes, not even france)

They wouldn't be carbon neutral, but they would obviously be a lot closer to that if they were generating (according to your plots) an additional 75TWh of nuclear power instead of lignite. This is indisputable.

I can praise their massive expansion of renewables while lamenting their massive reduction in nuclear power simultaneously. I've done both in this thread. These positions aren't at odds with each other

He really is hung up on namecalling anyone who doesn't agree with his premise right off the bat. He's more hostile than half the Conservative Nuke die-hards I know that don't recognize the need to work hand in hand with renewables.

And combined with something like the EBR-II (IFR), you could design a very fail safe reactor, EBR-II was tested against the failures that happened at Fukushima, Chernobyl, and Three Mile Island and it could self-stabilize in a meltdown situation and be started right back up without issue after a couple hours.

New Navy reactors IIRC are designed to be passively cooled as well, so it'd be incredibly difficult to damage the reactor, and I think SMRs are shooting for passive cooling as well.

Yeah that's what I meant, sure they'd still be burning some natural gas, but that would be about it. Shining city on a hill.
