Simply over six months in the past, in December 2021, I requested the query that was on the tip of the tongue of everyone who follows the topic of the continuing large “inexperienced” transition to fossil-fuel-free vitality. Really, that’s a lie. The query I requested was not on the tip of the tongue of everyone who follows the topic, and even of the general public who comply with the topic, for causes that to me are utterly inexplicable. The query was : “Which Nation Or U.S. State Will Be The First To Hit The Inexperienced Vitality Wall?”
The candidates that I nominated in that put up as probably the primary to hit the “inexperienced vitality wall” have been California, New York, the UK and Germany. On the time, I believed it was apparent that a kind of jurisdictions would hit the wall before nearly anyone anticipated. Certainly, I used to be fairly daring within the brief time-frame that I predicted:
A chronic interval of unfavorable climate (calm and overcast) may trigger a severe vitality crunch to hit one or each of Germany or the UK as quickly as this winter. Or they might get fortunate and go one other yr or two.
Now right here we’re in June 2022, and I believe it’s laborious to disclaim that Germany has in reality hit the “inexperienced vitality wall.” Let’s take into account.
First, right here is the definition of the “inexperienced vitality wall” that I gave within the put up:
[O]ne or one other of [those states or countries] is very prone to hit a “wall” — that’s, a state of affairs the place the electrical energy system stops functioning, or the worth goes via the roof, or each, forcing a drastic alteration and even abandonment of the entire scheme.
And right here’s the rationale I gave why one or one other (or all) of the nominated jurisdictions would quickly be hitting the “wall”:
All these locations, regardless of their wealth and seeming sophistication, are embarking on their formidable plans with out ever having carried out any sort of detailed engineering research of how their new proposed vitality techniques will work or how a lot they’ll price. Positive, a wind/photo voltaic electrical grid can operate with 100% pure gasoline backup, for those who’re keen to have the ratepayers foot the invoice for 2 overlapping and redundant era techniques when you might have had only one. However “internet zero” emissions means no extra fossil gasoline backup. What’s the plan to maintain the grid working 24/7 when the coal and pure gasoline are gone?
As is (or needs to be) apparent to everybody, a predominantly wind/photo voltaic electrical energy era system wants full backup from some supply to maintain the lights on 24/7. The choices are few: fossil fuels crops (coal, oil or pure gasoline), nuclear, or storage (i.e., batteries). Germany has dominated out the fossil gasoline and nuclear choices. It by no means had a lot in the best way of oil-fired electrical energy era, and it spent the final ten-plus years phasing out its coal and nuclear crops. So, that leaves storage. Certainly, you would possibly assume, having launched into a multi-trillion greenback transition to a predominantly wind/photo voltaic electrical energy system, and having dominated out each fossil fuels and nuclear for backup, Germany should have been centered like a laser beam on the storage points to make the entire thing work.
You’d be unsuitable. It’s actually unbelievable the extent to which Germany — seemingly the nation with probably the most subtle engineering on the planet — put its head within the sand and ignored the storage downside till it simply ran its vitality system into the wall.
Let’s examine how a lot vitality storage Germany would want to again up its wind/photo voltaic electrical energy system to the quantity of storage really developed so far or within the pipeline. At this web site, I’ve adopted the vitality storage query carefully, and have mentioned and linked to probably the most competent calculations of how a lot storage can be wanted to again up a predominantly or absolutely wind/photo voltaic electrical energy system for numerous jurisdictions, together with Germany. In this put up in November 2018 I linked to and extensively mentioned work by a person named Roger Andrews, who calculated the storage requirement for Germany to again up a totally wind/photo voltaic system as roughly 25,000 GWH. In that put up, I additionally examined some explanation why Andrews’s calculation may be low — for instance, Andrews assumed a 100% return from vitality put into storage (which is unrealistic), and in addition based mostly his calculations on precise era and climate information for a specific yr (2016), which may show extra favorable than one other yr. However that mentioned, Andrews’s calculation appeared to me to be in the appropriate ballpark. Extra lately, in a put up in March 2022, I mentioned and linked to work of two German scientists named Oliver Ruhnau and Staffan Qvist. Ruhnau and Qvist calculated a storage requirement for Germany to again up a totally wind/photo voltaic system as 56,000 GWH.
For those who determine that Andrews could also be on the low facet, and Ruhnau/Qvist on the excessive facet, that might put a great tough estimate of Germany’s want for grid-scale vitality storage to again up a wind/photo voltaic system someplace within the vary of about 40,000 – 50,000 GWH.
So how a lot storage does Germany have presently present or within the pipeline? Right here is an April 11, 2022 piece from consultancy Wooden Mackenzie reporting excitedly about Europe’s plans to resolve the wind/photo voltaic intermittency downside with storage, “Europe’s grid-scale vitality storage capability will broaden 20-fold by 2031.”:
Europe has set out among the world’s most formidable decarbonisation targets. And the tempo of change is accelerating. . . . [T]he area’s nascent grid-scale vitality storage phase is rising quick. We forecast that whole capability will broaden 20-fold between now and 2031.
Right here’s their chart displaying what that “20-fold growth” will imply by 2031:
For Germany, this monumental growth will supposedly imply all of 8.81 GWH of grid-scale vitality storage. Is there a decimal place error right here? Sadly no. In opposition to a requirement of 45,000 GWH +/- of grid-scale storage, they’re not planning on 9000 GWH, and even 900 GWH or 90 GWH, however 9. They’re off by an element of round 5000 in opposition to what they would want.
In different phrases, they haven’t even begun to resolve the storage downside that might have to be solved to make their wind/photo voltaic system work, and they’ll barely if in any respect have begun to resolve it by 2031. Certainly, the issue might not be solvable in any respect, and as but they haven’t actually put any significant effort into making an attempt to determine that out. The end result, as everyone knows, is that they left themselves utterly depending on pure gasoline from Russia. Now the Russian gasoline is successfully unavailable, and different potential sources have seen inadequate provide and big worth spikes. Listed below are just a few observations on Germany’s present vitality predicament. From Walter Russell Mead within the Wall Avenue Journal, June 27, “Finish of the German Idyll”:
As lately as 2020, nearly all the world agreed with the smug German self-assessment that Germany had the world’s most profitable financial mannequin, [and] was embarking on probably the most formidable—and largely profitable—local weather initiative on the planet. . . . [Now we understand that] German vitality coverage is a chaotic mess, a shining instance to the remainder of the world of what to not do. . . . Inexperienced vitality, regardless of large German funding, will probably be unable to produce German trade with dependable and low cost energy for a very long time.
From Vitality Intelligence Group, June 28, “King Coal Makes Comeback in Europe”:
[German] officers are engaged on emergency legal guidelines that might permit roughly 9-10 gigawatts of idle coal and lignite capability to return to service till 2024, changing among the 16% market share now held by gasoline. The nation is dwelling to seven of the EU’s 10 most polluting energy stations, based on NGO Ember. . . . Financial system Minister Robert Habeck mentioned legal guidelines permitting extra coal use and fewer gas-fired era ought to move the Bundesrat — higher home of parliament — in early July. . . . The federal government says there aren’t any plans to vary the coal phase-out date, with the final items nonetheless earmarked for closure by 2030.
It’s a whole reversal of the prior coverage of shutting down the coal crops. Financial system Minister Habeck says that the reversal is non permanent, and that they’re nonetheless on observe to shut all of the coal crops by 2030. And the way precisely are they going to perform that, with all of 9 GWH of grid-scale vitality storage? There is just one attainable methodology, which is to return to pure gasoline, both utilizing different suppliers (U.S.?), or as a result of Russia re-enters the great graces of the world. However utilizing pure gasoline for backup is simply as a lot a whole abandonment of the “internet zero” fantasy as is utilizing coal.
So I say that Germany has in reality hit the “inexperienced vitality wall,” and won’t be going again, it doesn’t matter what they’re saying in the meanwhile.
