In Switzerland today, a pumped hydro facility started operation

20GWh capacity

A new pumped-storage station in one of the highest and remotest parts of Switzerland will help cope with fluctuations in wind and solar-power supply. It can stabilize electricity output for the whole of Europe.

“The electric storage capacity of the reservoir surpasses that of 400,000 electric car batteries,” explains Alain Sauthier, engineer and director of the Nant de Drance pumped-storage hydroelectric plant, pointing towards the Vieux Emosson reservoir. This artificial lake was built in 1955 in the municipality of Finhaut, high in the Alps of the Swiss canton of Valais.

“It is an ecological battery that uses the same water over and over. The output is more than 80%: for every kilowatt hour of electricity used to pump the water upstream, 0.8 is fed into the grid,” Sauthier explains.

...the glaciers in Switzerland disappear because we bet the planetary atmosphere on replacing nuclear energy with stupid fantasies about storing trivial amounts of expensive and useless wind and solar while burning coal.

Egli, P. E., Belotti, B., Ouvry, B., Irving, J., & Lane, S. N. (2021). Subglacial channels, climate warming, and increasing frequency of Alpine glacier snout collapse. Geophysical Research Letters, 48, e2021GL096031.

Excerpts:

Alpine glaciers have been retreating rapidly since the 1980s because of rapid climate warming (Diolaiuti et al., 2011; Fischer et al., 2015; Haeberli et al., 2007; Paul et al., 2004; Sommer et al., 2020). The retreat is forecast to accelerate in the coming decades (Zekollari et al., 2019). The primary mechanism of mass loss for Alpine glaciers is surface melt (Arnold, 2005; Oerlemans & Knap, 1998; Vincent et al., 2004). Negative glacier mass balance can also be driven by reduced snow accumulation. Less considered is basal or internal ablation. This can involve the collapse of subglacial channels in the snout marginal zone, driven by thinning ice combined with slow creep closure. After the collapse, ice is removed via the channel to the glacier outlet.

This mechanism of glacier retreat was first described some time ago as “subglacial stoping” or “block caving” (Loewe, 1957; Paige, 1956). There are very few documented or quantified examples of this process (Bartholomaus et al., 2011; Dewald et al., 2021; Kellerer-Pirklbauer & Kulmer, 2019; Konrad, 1998; Lindström, 1993; Stocker-Waldhuber et al., 2017). As a result, little is known about where and when collapse features form and whether or not their formation frequency is changing due to climate warming...

...The frequency of collapse features in Alpine glaciers has increased markedly since 2000. Such collapse is associated with glaciers that tend to have lower rates of longitudinal ice flux and so reduced compression and longitudinal closure. Low longitudinal flux is a consequence of glacier thinning related to a tendency for Alpine glaciers to have a negative mass balance due to climate warming. Glacier thinning leads to a longterm reduction of flux of accumulated ice into the ablation zone. Thus, the frequency of collapse at Alpine glacier margins is likely to increase as climate warming continues.


Since 2000...2000...um...2000...why does that year stick in my brain? Oh, I know. That was the year that in 1976 the anti-nuke shithead Amory Lovins implied strongly that we "could" have 16 "quads" (EJ, roughly) of solar energy in the United States. We don't have that on the entire planet, but it's the thought that counts.

It's nice to see "I'm not an anti-nuke" antinukes using units of energy, albeit the derived unit GWh. 20 GWh works out to be 72 trillion joules, slightly less energy than that contained in a single kg of plutonium, 80.3 trillion Joules.

It's a stupendous - and let's be careful to use "percent talk" - 0.000012% of the roughly 600 EJ that humanity consumes each year.

At peak capacity - which in theory can only be utilized 50% of the time at maximum, but will actually will be available for much smaller fractions of a day, it's the equivalent of an 833 MW power plant.

Earth shattering, quite literally.

What's the theory? As of this writing German coal based power output is 19.3 GW, compared to it's wind output of 16.7 MW.



Electricity Map Germany 2200hBerlin220701

Which form of German energy is this water "battery" going to store at 80% efficiency? Or are the Swiss just going to wait until the wind is blowing real, real, real, real, real hard in Germany to fill this daydream up or are they going to waste the power generated by coal?

Have a very pleasant 4th of July weekend.

I will be interested in the results going forward, since it's not a future plan but now operational.

The grid always has times where there is excess capacity and no buyers.

I wonder, how will they report it's usage? Will your ElectricityMap add another category? Will the operation reveal where the power came from that was used to pump water from the lower basin to the upper basin?

Happy 4th to you as well.

Edited to add - ElectricityMap.org did add Hydro Storage with fields on both sides (left side to pump water up - right side to show water producing electricity). They show 4.49 GW capacity.

...where that country is not burning dangerous fossil fuels and dumping the waste directly into the planetary atmosphere and are storing pure excess so called "renewable energy."

I look at this map frequently to obviate my disgust with Energiewende and I've never, not once, seen it.

I've seen plenty of insipid remarks on this website over the last 19 years, where the selective attention crowd picks out a 20 or 30 minute period, usually when demand is extremely low, where solar and wind are producing almost 100% of the energy in some locality, crowing insipidly, while ignoring the other 23 hours and 40 or 30 minutes where fossil fuels are being burned.

If some 20 minute period ever exists where this happens, computers all over the world will gear up to shout about it, as they did recently in the case of California.

Even the cheering for solar and wind, never mind the production of energy itself, requires fossil fuels.

I have never seen this obscene inattention to reality with respect to Germany. Not once. And let's be clear, because it would be an extremely rare event, it would be international news.

It's discussed to a limited extent that the Germans are working to kill Switzerland's glaciers.

It follows that they are storing energy that is generated using dangerous fossil fuels.

Since advocates of the expensive, grotesquely failed "renewables will save us" scheme have contempt for science, science being engaged with reality, they routinely demonstrate contempt for the 2nd law of thermodynamics.

One would need to be a stupid as an anti-nuke to not understand how hydrostorage works. I certainly don't need it described. I only note that since the energy stored is generated using dangerous fossil fuels in Germany, the filling of hydrostorage facilities is destructive, not only to the vast river basin that can store as much energy as a kg of plutonium, but to the atmosphere as well.

The fact that people cherry pick to praise the wasting of energy as if it were clean and green is why we have seen an increase of nearly 50 ppm in the concentrations of the dangerous fossil fuel waste carbon dioxide while anti-nukes praise the willful destruction of exergy.

The hydrostorage in Germany is obscene, given the reality of energy production in Germany and the fact that storing energy wastes energy. It would be unnecessary if they had not only destroyed their nuclear infrastructure in an orgy of stupidity, but rather had expanded it.

Have a pleasant Saturday.

The Swiss have mainly hydro, nuclear and solar as their electricity producers. They have no coal and very little gas and oil.

The article plainly states that they are pumping the water from one reservoir to another. Nothing about getting supply from a river.

They also state that it is 80% efficient.

The number missing in all this is the cost to keep a power plant that uses steam to drive turbines on the ready to balance loads on the grid. If you are using steam for this then the boilers have to be kept at temp and ready to use, waiting for the need to arise - talk about wasted energy. That is the one function that the pumped hydro system in Bath County emphasized. It's also what battery storage does so well because they can respond instantaneously - no delay.

7. Let's not play pretend: The article in the OP refers to doing away with NUCLEAR energy.
Sat Jul 2, 2022, 02:33 PM

Of course it does. It's why it's popular with anti-nukes.

Perhaps if one read it, one would note that.

The asshole praising this energy wasting hydro storage system wrote:

“In the future, it will be increasingly necessary to store large amounts of electricity, as renewable sources gradually replace nuclear and fossil energy.”


I added the bold in case anti-nukes want to pretend they didn't see it.

It's cute that anti-nukes now include a rote interest in displacing fossil fuel energy. Of course, in reality they've never given a shit about fossil fuels, it's a late add on. Of course this hydro engineer could look down the hill to Germany to see how fucking great replacing fossil fuels with so called "renewable energy" is. It's international news, Germany, which now is matching Denmark for the most expensive electricity in Europe, and talking about shutting industries, cannot get enough fossil fuels to run the country reliably.

If Switzerland is generating hydro energy and then storing it by pumping, this is the classic example of a perpetual motion machine, which of course would certainly be acceptable in "renewables will save us" circles but laughable everywhere else.

So mentioning that Switzerland produces hydro energy, temporarily at least until climate change destroys its glaciers, should be irrelevant in a rational conversation, one that respected the laws of physics.

The Electricity Map shows imports and export, those little flowing arrows. Right now as of this writing Switzerland is importing 2.41 GW of dirty power from, um, Germany, where the carbon dioxide intensity of electricity is currently 355 grams of CO2/kwh, and 1.96 GW cleaner power from France, where the carbon intensity is currently 80 gm CO2/kwh.

In "percent talk" 80/355, the carbon intensity of France is 22.5% that of Germany.

If the Swiss are storing German electricity with this stupid system, they are making climate change worse, not better. If they are not storing energy, they have simply built a system that is immediately (and undoubtedly often) as useless as a wind turbine in dunkelflaute.

It's appalling, how, with the planet's atmosphere collapsing, how selective the attention of anti-nukes is. They are in general, never concerned with nitpicking through an argument, as in for example, complaining (for 43 years) about the cost of "cleaning up" Three Mile Island in an area, Pennsylvania, where the price of electricity is 20% (again in "percent talk" ) that of Germany while not giving a damn about the cost of cleaning up the entire fucking planetary atmosphere, a cost and need exacerbated by the grotesque stupidity of Energiewende in a country connected directly to the grid of Switzerland and neighboring it.

Have a pleasant evening.

They wrote:

We are working on the price differential: we need to react quickly and pump when the price is low and turbine when it is high. In the past, we used the turbines by day and pumped by night, but now the situation has changed, with consumption peaking late in the evening,” the plant’s director says.

You see it as a lost energy exchange, they are applying the cost of the energy. It is without a doubt a cleaner way to generate electricity when demand is high.

RE: Swiss shutting down nuclear plants

Neighboring Germany is due to abandon nuclear power stations by 2022, while Switzerland’s government has said it would build no new nuclear reactors and decommission its existing plants at their end of their lifespan.

The Swiss decision to quit nuclear power was upheld in a 2017 referendum which also supported government plans to push forward sustainable energy with subsidies to develop solar, wind and hydroelectric power.

Sat Jul 2, 2022, 05:36 PM

...clerk who reduces all issues to money.

Energy has an external cost, the cost in destruction of human beings, flesh, etc.

This cost has more consequences than an account balance in a Swiss Bank.

As an environmentalist, I think we should pay more to make a sustainable world. I know this goes entirely over the head of antinukes, since they lack a sense of ethics.

As for the referenda, we live in times where ignorance is very popular and widely endorsed.

Suppose we didn't have a huge Greek chorus carrying on loudly about say, Three Mile Island, Fukushima and so on? Suppose we actually looked at stuff that kills people instead of shit for brains nonsense that if any radiation escapes anywhere at any time it's the end of the world?

Would Switzerland have a referendum endorsing climate change then?

Again, given the rhetoric I hear here from "I'm not an anti-nuke" anti-nukes, repeating endlessly, year after year, decade after decade, four decades in the case of Three Mile Island, three decades in the case of Chernobyl, and over a decade in the case of Fukishima the same fucking tiresome and destructive rhetoric, given the wide distribution of this rhetoric, I doubt it.

Anti-nuke rhetoric kills people, more people than have died from Covid because of anti-vax rhetoric.



Three Mile Island's accident began on March 28, 1979. In that week the concentration of the dangerous fossil fuel waste carbon dioxide on this planet was 339.18 ppm as measured at Mauna Loa, 81.69 ppm lower than that reported for the week beginning June 19 of this year.

Which cost more lives? Which cost more money? Three Mile Island or climate change? Three Mile Island or air pollution? Do our money obsessed anti-nukes got a bean to count and throw my way?

Chernobyl's accident began on April 26, 1986. In that week the concentration of the dangerous fossil fuel waste carbon dioxide on this planet was 350.08 ppm as measured at Mauna Loa, 70.79 ppm lower than that reported for the week beginning June 19 of this year.

Which cost more lives? Which cost more money? Chernobyl or climate change? Chernobyl or air pollution? Do our money obsessed anti-nukes got a bean to count and throw my way?

Fukushima's destruction by a earthquake disaster in which 20,000 people died from seawater and few, if any, people died from radiation exposure, took place on March 11, 2011 In that week the concentration of the dangerous fossil fuel waste carbon dioxide on this planet was 391.46 ppm as measured at Mauna Loa, 29.41 ppm lower than that reported for the week beginning June 19 of this year.

Which cost more lives? Which cost more money? Fukushima or climate change? Fukushima or air pollution? Do our money obsessed anti-nukes got a bean to count and throw my way?

Again, to drill it into tiny minds, anti-nuclear rhetoric, whether it gets to the endorsement of the Swiss or not, kills people, more people in fact than anti-vax rhetoric has killed. If, as the Lancet report indicates, air pollution kills 6 to 7 million people per year - it may have been higher 40 years ago - air pollution killed somewhere between 250 million and 300 million people since 1979, when Three Mile Island's reactor #2 melted.

Do anti-nukes ever mention this? No. They don't. They do - I've seen it right here in this forum recently in 2022 - still carry on about Three Mile Island though.

Right here in this forum, during the invasion of Ukraine, we had anti-nukes carrying on about the shelling of a nuclear plant - which ended with no appreciable radiation leaks - while the Russians, funded with MONEY provided by Germany on the theory that nuclear energy is "too dangerous," were blowing human beings to tiny pieces with dangerous fossil fuels diverted to weapons.

There is a reason that I hold anti-nukes in contempt, and the reason is that I am more concerned with human values, and in particular the rights of future generations and the maintenance of valuable ecosystems and they are more concerned with MONEY, in particular their money.

We don't even remotely speak the same language.

This is why anti-nukes complain so loudly about the cost of nuclear plants after pushing rhetoric to be sure that they are as expensive to build as possible - again arsonists complaining about forest fires. The benefits and wealth provided by nuclear power plants will not accrue so much to the generation that builds them, but to every generation that follows.

Now if Switzerland has held a referendum to kill people and deprive future Swiss generations of their glaciers by phasing out nuclear power, this does not mean anything at all that is estimable in my view. Apparently it's OK with anti-nukes, but not me. Anti-nukes are in fact happy about it. They have proven that they are great marketeers.

History seldom records that what is popular is also wise. Human slavery was once very popular in the United States. Anti-Semitism was very popular in Germany between 1925 and 1945. Hell, invading Iraq was popular in recent times.

The confusion of what is popular with what is wise or good is known as the Bandwagon Fallacy.

In this connection, on being told that 100 authors had participated in writing the book Hundert Autoren Gegen Einstein (One Hundred Authors Against Einstein), Einstein quipped, "If I was wrong, one would have been enough."

The popularity of anti-nuke rhetoric in Germany and/or Switzerland will kill people, clear and simple.

Arguably, along with the air pollution and climate deaths, the money aspect is killing Ukrainians, since the German energy program funded Putin.

The fact that solar and wind energy play a huge role in the popular imagination and are widely cited as being a means of addressing climate change has nothing to do with the reality of whether or not they can or will address climate change. On the contrary, it has been experimentally determined, at a cost of trillions of dollars, that they are completely ineffective at addressing climate change. The entire 21st century has made this indelibly clear.

If the idiot rhetoric of bean counters musing about the cost of "cleaning up" Three Mile Island - this to an arbitrary standard no other system can match in terms of damage to the environment and human cost - this does not mean that Three Mile Island was a major disaster comparable to climate change.

I don't fucking care if Switzerland has voted for national suicide. The dam lauded in the OP is not worth the carbon making the concrete for it. It's a disgrace.

Antinukes can talk all they want about money. It fits their mentality exactly. They're bourgeois materialists through and through. Experience teaches me that they have the ethical depth of slime molds, not that I wish to demean slime molds as in many ways slime molds are more interesting. Despite much rhetoric to the contrary, no amount of money can change the laws of physics, the same laws that govern energy and in fact, the health of the planet.

I'm not sure that I'll have time to address yet another intellectually dishonest or silly quibble. If I don't have a great holiday weekend.

10. As much energy that is created in a nuclear power plant
Sat Jul 2, 2022, 06:11 PM
Jul 2022

Lets talk about how much is wasted? What is the typical efficiency of a current nuclear power plant? Google says about 35%

Co-generation gas plants can have thermal efficiencies above 60% according to google.

The Hydro Storage facility in the OP is at 80%. For every Kwh used to pump water up, they get 0.8 Kwh in return. They say they can change from pumping water to making electricity in 15 min. Sure beats having some fossil fueled plant on standby, burning fuel to keep the boiler hot just in case it's needed...

BTW, I thought the Swiss stance was reasonable once they decided to not to build any more new nuclear plants - keep the existing plants operational through their useful life, one Germany should adopt.

A modern nuclear plant generates primary energy.

An energy storage system wastes primary energy.

I have argued in this space for higher efficiency for nuclear plants using heat networks. It is, in fact, the challenge I offered my son as he begins his research.

Unfortunately, most of the posts I've written on this score involve a knowledge of science and thus is far out of the purview of anti-nukes.

The problem with anti-nukes is that when they're not reactionary, they're conservative. They believe that the technology that built the nuclear infrastructure is fixed in the 1960's technology utilized to build the nuclear plants they hate was fixed forever. They're examples of Churchill's quote (when he was a liberal) that a conservative is a person who believes nothing can be done the first time.

If anti-nukes would take their heads out their asses, they might recognize that this is 2022. The advances in materials science in particular, the key to utilizing high temperatures - and in fact the technology utilized in the combined cycle gas plants that make solar and wind energy's dependence on gas slightly less odious - is the key to high efficency.

The word "science" is not one they value however. It takes away from the value of their chanting in contempt of engineering which kind of mirrors their contempt for humanity.

You pump water when power is cheap and make electricity when demand is high.

If they are able to use excess electricity from wind farms to pump water, then that conserving what would be wasted. There are times when wind farm practically give away their power because it come at a time of low demand. Hydro storage gives the grid a supply that would otherwise come from a plant using fuel.

BTW, today at 4pm the Swiss are exporting to Northern Italy about twice what they are importing from Germany and France.
