Want a clean energy transition? Better start putting cash into electrical grid

Serious question

(Top-posting in an attempt to drag the forum back on topic)

Do we have enough copper and lithium to do this?

Do the macro-economists really think that if copper is $6000/ton (say) and we need 100 million tons of copper to build all these new electric grids, that we (the world) could actually buy 100 million tons without affecting the price of copper? How about the labour market of people trained in HV electrical engineering?

Throwing billions at something without first improving the entire supply chain usually just makes it more expensive. Just ask HS2 Ltd.

Then there's the small issue that electricity imports are the ultimate in "just-in-time economy". It's pretty much impossible to store on any useful scale (the best we have is on a scale of minutes)..

Boris Johnson's mad hydrogen for homes bubble bursts

Re: Capacity

When it's -really- cold outside, the air is also very dry, because all the moisture has er, freeze-dried out of it.

The most unsuitable weather for heat pumps, is when it is cold and damp, just a smidge above freezing outside.

In other words, exactly the sort of weather that the UK has very often but US, Europe and Scandinavia not so much.

Your heat pump will run for a few minutes, ice-up, and have to run backwards for a few minutes to de-ice itself. When that de-ice ratio reaches 50% then it is just sitting there using power but doing nothing useful to heat your home.

But .docx does not comply with its own "OOXML" spec, and Microsoft can tweak that noncompliance at will. They could even wilfully bork (i mean, upgrade to the latest non-spec) documents uploaded to linkedin so that they don't work even if the original would have done.

It's not Libreoffice's fault if MS keep moving the goalposts.

Nuclear-powered datacenters: What could go wrong?

Fukushima was a very old design of plant that was hit by a terrible natural disaster - the tsunami itself killed about 50,000 people IIRC

Yet the "nuclear catastrophe" killed no-one. Even the 50 who went in expecting to die have been happily disappointed.

As I see it, Fukushima was a triumph of nuclear safety.

Plenty of seawater though, no?

You don't -have- to evaporate it. But if you do evaporate, you could condense it back and get a free desalination plant

Re: Fast Neutron reactor

These costs are caused by the utterly barmy regulations around nuclear (which seem to have been deliberately designed to poison the industry and stunt its growth), and the parasite industries that have grown out of those regulations.

The real problem with radioactivity is that it is so detectable in tiny amounts, and scary because people think it causes cancer, when really it's not going to cause harm at all in small amounts. Even pretty large amounts such as the dose received by the Fukushima 50, nuclear bomb testing engineers etc. have not caused anywhere near as much harm as we all expected. Why? Because life on earth has evolved to cope with quite a lot of ionising radiation in the background. The radiation was there before life was. Whereas we have NOT evolved to deal with microplastics, nanoparticulate carbon (which ironically exist in modern ULEZ-compliant diesel exhausts but not the old ones..) etc. etc.

The regulations at Sellafield are so ridiculous that they are measuring single Bequerels outside casks and saying that's too high. Literally if you can detect a single photon of gamma, it can't be shipped out. This I heard from someone who works in safety at the place.

I knew a project manager from that place too.. He said that the workers there would all conspire to make sure any new project manager would fail at his or her job, and would just get so frustrated that they eventually either quit or let the guys do whatever they want.

That is why decommissioning is so expensive. It's not just nuclear regs, it's UK Health&Safety legislation too, and in terms of cost the two are multiplicative.

But without bloody revolution, societal poison just never goes away. So I agree, the age of nuclear is over. Until someone drops a bomb on our heads and suddenly sellafield is the least radioactive place in Britain

Re: Interesting

> the fluctuations in the spot electricity market are a sign of a functioning demand-and-supply market. Price goes up the Aluminum plant decides it can do without leccy today, price goes down electrolyse the crap out of that cryolite.

My point is that you need fluctuations not just in the price but in the demand, to say that it is working. If the market were functioning then you would see the demand drop as the price goes up. But if you take a look, you can see the price goes from -50 to +200, or the opposite, in the space of an hour. Does the demand change? Not a jot.

The price has changed sign, the demand stays the same. That does not tell me that the market is functioning.

The aluminum plant, for technical reasons, can't just start or stop the plant at the drop of a hat when the sun is or isn't behind a cloud. It has staff to get out of bed, equipment to prep. If a smelting plant stops suddenly mid cycle it could be damaged beyond repair. It is equally daft to assume it is always ready to start up. If the owner wants to maximise the profit of his very expensive plant, he runs it flat out 100% of the time, or at least when the staff are awake. All of this load shifting stuff is utter bollocks.

Octopus and NG trumpet that their Demand Flexibility Service saved a whole 3GWh of electricity last year, which sounds a lot, but it is 6 minutes worth of leccy for the country, or about 0.0001℅ of the year

Re: Interesting

Like I said, the "free-marketeers" <spit> would just love this.

Just take a look at the graphs on "Drax Electric Insights". The price already fluctuates all over the place, from minus the average price to well over four times the average price, but this is rarely reflected in the demand graph. That shows that the "free market" system is a complete failure. People use energy when they need it. You don't say "oh the price is low today, better cook two roast dinners instead of one" and you don't expect your car to be empty in the morning when you need to go to work, because the price was high and it discharged.

The problem with all this is that it pushes the price well above what people can afford. It's just more pigswill for the electricity companies when they are the only game in town, after we get rid of gas and oil.

Re: Lights @midgepad

"Keeping the lights on" is just a phrase meaning keeping the electric grid running. It's also the name of a rather good column on the subject in Private Eye.

When I said "the lights go out" I meant a loss of supply, nothing to do with lights specifically.

You must be one of our new American guests, How do you do

Re: Would a company really install a nuke?

And that's why private companies and PLCs should never be allowed anywhere near state utilities.

What are you blathering on about?

To be fair, the extra inertia provided by a nice big steam turbine like those found in a NPP, could have improved a grid's tolerance even to faults like insulator flashover. The transmission network has redundant circuits and automatic re-closing circuit breakers, so as long as there is enough inertia, the blackout only lasts a few seconds while the grid finds another route.

But if all you have are non-synchronous generators such as wind, solar and HVDC import cables, then in the event of a fault, the grid frequency can rise or fall so rapidly that everything has to disconnect to protect itself. And that's when you get a total blackout.

But I guess the lobbyists would have found that hard to explain to the general public

Re: Nuclear fanboys keep looking for a business case for SMRs

That argument is circular, and unhelpful. The cost of nuclear power comes from the regulations and the parasite industries that have grown out of those regulations.

What is the LCOE as you put it, of nuclear power in China? Is that not a 'Habitable latitude'?

Re: Interesting

Well I did say long-term/permanent downfall..

I think renewables would just mean intermittent and unequal service. I.e. If the wind stops blowing, the lights go out except for those who want to pay extra for their 'smart' meters not to disconnect them.

We could end up with an auction-style system, whereby however little electricity we have is supplied to the highest bidders. The "free-marketeers" would just love that, and I think the likes of Microsoft would put up with it, IF they thought that a high bid was enough to guarantee service. This SMRs thing suggests that they think the grid might go down completely, for a long time.. Scenarios for that are: 1: low inertia causes a nationwide outage and the "black start" plan fails to restart the grid in an acceptable time, or 2: enemy action.

Given how reliant we are becoming on subsea interconnectors for example, and the state of geopolitics, i'd say the latter is likely

Nukes, schmukes – fuel cells could power future datacenters

Re: Efficiency is ~40% if you ignore the heat generated in the process.

When I said 40%, i was only considering the electrolyser and fuel cell components, which are about 50% and 80% respectively.

0.5*0.8=0.4

But as others have pointed out, the cost of compressing the hydrogen for storage is extremely non-trivial, possibly dwarfing the input cost of electrolysis.

Saying we can recover the heat and use it for district heating is the same as saying we can recover low grade heat from gas, coal and nuclear plants. We can, and that's called CHP. But we don't usually bother, because it's very complicated and expensive, and the plant isn't always running at the same time as the heat is needed. It's also a completely separate argument to the Hydrogen debate, because it applies equally to other fuels.

I need the Paris icon again

Have I read that right? Electrolysis of water is no more than 50% efficient, so the "energy used to produce it in the first place" is about twice as much as the energy that it stores. Three times that would be six times the energy of the stored hydrogen.

I know that liquefying Hydrogen (by cooling it to 1/10 of the absolute temperature of LNG) is expensive, but is it really this expensive? Shurely shome mishtake, or else nobody would be wasting their breath debating the usefulness of liquid Hydrogen as an energy store..

..right?

You seem to be conflating "synchronous condensers" aka rotating stabilisers, with flywheel-based energy storage.

Synchronous condensers are useful for adding AC inertia to a grid, stabilising the frequency, and they are quite well established for that. But they do not store a significant amount of energy. They will spin up and down in minutes or even seconds. Certainly not hours, never mind days

Flywheel energy storage on the other hand, intends to store a much greater amount of energy, and is not well established. It's also incredibly dangerous, far more so than the equivalent sized battery. When flywheels fail, they fail suddenly and spectacularly.

Flywheels absolutely cannot "smooth out renewable peaks and troughs" as you claim. The best they can do is prevent "grid islanding" by keeping the frequency stable for the two seconds that it takes for the grid to re-route following a fault.

> It's better than free... rather than paying people a premium to not generate electricity you pay them less than that to generate the electricity... you also then get to *not* pay someone else to burn crap later on.

Of course, I agree with you. But in our weird hodge podge of the worst elements of capitalism and communism where we hand out bungs and subsidies to private companies, the wind farm operators may well prefer to be paid for generating nothing (saving on maintenance costs, perhaps, of certain components), than being paid nothing for generating something.

But even if the energy were free (it isn't, even if we could scrap the subsidies) where are we going to get the raw materials for all these electrolysers and fuel cells? And where and how are we going so store the hydrogen?

It leaks if stored under pressure, and there all kinds of weird and wonderful issues if you store it as a cryofluid. The latter obviously taking a bit more energy, too.

Fuel Cells and Elecrolysers both work, if you have enough Platinum to build them.

Efficiency of the whole process is ~40%, from electricity in to electricity out, so it has to be on the pretense that excess, otherwise-curtailed wind power is 'free'.

But at the moment, wind generators get lots of money in subsidies when they are told to shut down. So is the excess energy really 'free'?

And if everyone tried to build electrolysers and fuel cells all at once, the price of both platinum and copper would rocket.

They work at 1.5 Volts (unlike Lithium batteries which have 4 volts per cell) so you need an awful lot more current and an awful lot more copper per cell, and you have to plate the electrodes in Platinum ...

So it is certainly not cheap. It may yet be cheaper than Nuclear, but that isn't saying much.
