Let me welcome to the small and elite membership of important thinkers on the supposed vitality transition a man named Balázs Fekete. Fekete, with a number of co-authors, has lately (September 18) succeeded in getting an article printed in a journal known as Frontiers of Environmental Science, with the title “Storage necessities to mitigate intermittent renewable vitality sources: evaluation for the US Northeast.” Fekete then adopted up by publishing on November 14 at Judith Curry’s Local weather, And many others. weblog a prolonged submit summarizing the article, titled “Internet-Zero Targets: Sustainable Future or CO2 Obsession Pushed Lifeless-end?”
As with the earlier competent analyses of vitality storage necessities wanted to again up intermittent renewable era which were featured on this weblog and in my vitality storage Report, there may be nothing sophisticated in regards to the Fekete, et al., evaluation. The authors name it “a modified surplus/deficit calculation [as] taught to water engineers to dimension reservoirs for assembly water demand when the water sources differ.” When there may be surplus manufacturing you add it to storage, and when there’s a deficit you subtract; and then you definitely sum over a 12 months (or two, or ten) to calculate how a lot storage you want. It’s all primary arithmetic. What may very well be less complicated?
You’ll not be stunned that the conclusion is “CO2 obsession pushed dead-end.”
This topic would appear nearly too apparent and trivial to cowl on this weblog. There’s nothing sophisticated right here. Everyone who’s concerned in any method within the vitality transition sport, and who has even the bottom stage {of professional} competence, merely should pay attention to this topic and of those calculations. And but I simply attended the massive New York “Local weather Summit,” (aka the Krazy Klimate Konference), that includes the entire highly effective politicians and bureaucrats and business leaders who’re in command of our state’s vitality transition, and to an individual they don’t know about any of this. And by no thought, I imply none, zero, zilch. One man even got here as much as me and accused me of being “impolite” for laughing out loud at his astounding ignorance. (The one different risk was that it was intentional comedy.)
Unsurprisingly, the authors of Fekete, et al., make no declare to being “local weather scientists.” Local weather scientists as a category are method too good to stoop to doing primary arithmetic. Within the intro to the paper, Fekete identifies himself as a professor on the Metropolis College of New York — of Civil Engineering. Second writer Mihály Bacskó is a former govt of the Hungarian Energy Firm. The opposite two co-authors are meteorologists working on the College of Oklahoma. In different phrases, the main target right here shouldn’t be on scaring the general public with horrifying situations from the occult voodoo of local weather “science,” however slightly solely on whether or not the proposed options will or is not going to work.
The actual calculations in Fekete, et al., take a look at knowledge from twelve states of the northeastern U.S. — New England, plus New York, New Jersey, Pennsylvania, Delaware, Maryland and West Virginia. Somewhat than utilizing manufacturing knowledge from present wind and photo voltaic services, the authors obtained each day wind pace and photo voltaic irradiation knowledge for the area. For consumption knowledge, the weblog submit states that the authors utilized an assumption of “fixed vitality consumption,” after figuring out that “seasonal differences of vitality consumption are comparatively small (deviate by solely 10-15% of the annual common).” (Maybe this choice may very well be criticized, however I doubt that it makes any materials distinction to the conclusion.)
And the underside line is:
The storage capability wanted to align energy era from photo voltaic or wind is round 25% of the annual vitality consumption.
In different phrases, you want three months price of storage to attempt to make this work. Earlier research that I highlighted in my vitality storage Report — for instance, these of Roger Andrews and Ken Gregory — had calculated storage wants within the vary of 1 to 2 months. Nonetheless, these research solely used one 12 months’s price of information for every calculation, and allowed working the storage stability proper right down to zero. For those who suppose that it’s too dangerous to run the storage proper right down to zero earlier than the stability begins to refill, then three months of storage is a way more affordable determine. Certainly, it’s nonetheless slightly conservative.
Fekete, et al., don’t get into the specifics of price of any attainable storage answer. However then, they don’t have to. The potential prices are so monumental as to fully rule out any try even to start out down this street. In keeping with the U.S. Vitality Data Administration, complete U.S. electrical energy consumption in 2022 was simply over 4 trillion kWh. So one-quarter of that may be simply over 1 trillion kWh. Simply to get an thought of the price of that a lot vitality storage, this website (Tesla followers) provides a (extremely optimistic) price for Tesla batteries of simply over $100 per kWh. So a trillion of these will run you about $100 trillion. That’s 4 occasions your entire U.S. economic system. In the meantime, a Tesla-style battery shouldn’t be remotely as much as the job of the vitality storage wanted to again up wind/photo voltaic electrical energy era, which might essentially embrace the power to avoid wasting up energy over a 12 months or extra and discharge over a 12 months. However then, the economics are so wildly out of line that it’s hardly price worrying about such technicalities.
Fekete, et al., in a really understated method, put it this fashion:
Within the absence of vitality storage know-how that may retailer a number of months price of vitality, one has to conclude that every one research suggesting that photo voltaic or wind are value aggressive with different types of vitality must be retracted.
The Fekete weblog submit at Local weather, And many others. comprises two different topics of curiosity. One pertains to the peer assessment course of. It seems that one of many peer reviewers made a run at getting the paper blocked, with out stating the character of any substantive criticisms:
One of many reviewers said that “The manuscript comprises elementary errors that can not be rectified via writer revisions” with out venturing into any particulars.
Fekete calls this effort “unscientific, unjust, and unethical,” which is once more fairly an understatement. Sadly, such conduct is the norm in what goes by the title “local weather science” immediately. Happily, on this case, one other reviewer was supportive, as was the workers of the journal.
The second topic of additional curiosity within the weblog submit is that one other reviewer criticized the draft paper for alleged “lack of references to the “plethora of labor” associated to integrating renewables to the present vitality programs and transitioning to a sustainable vitality future.” The criticism brought about the authors to “roll up their sleeves” and exit and assessment some 360 papers really useful by the critic. Here’s a record of what they discovered:
- The inter-annual and seasonal differences had been hardly ever studied.
- The overwhelming majority of the research had been restricted to diurnal and minute-by-minute variations.
- The publications solely investigated using few hourly storage capacities.
- The first sustainability metric was lowering CO2 emissions.
- Many of the publications had been restricted to low renewable penetration.
- No publication tried to handle full decarbonization.
- Even probably the most bold “deep decarbonization” situations stopped at 25-50% renewable contributions that was thought of “excessive renewable penetration”.
And in abstract:
Many of the reviewed papers assumed that photo voltaic and wind will likely be at all times supplemented by some type of “agency era capability”, which is the obfuscated title of utilizing fossil fuels complemented with “carbon seize and sequestration”.
In different phrases, the orthodox “peer reviewed” scientific literature is sort of fully missing in consideration of a very powerful, elementary drawback of transitioning to an vitality system based mostly on electrical energy generated by the wind and solar. Effectively, now there may be one competent paper within the combine. They may do their finest to disregard it, at the very least till the entire wind/photo voltaic factor has conclusively proven that it will probably’t work.
