A Shockingly Inept Report From The IEA On Battery Storage Of Energy

From the MANHATTAN CONTRARIAN

 Francis Menton

In my self-designated role critiquing various schemes for total transformation of the world energy system, I get to review large amounts of poor, shoddy, and incompetent work. When people get into advocating for this “energy transition,” the stars regularly align to bring forth the most extreme levels of ineptitude. Start with the fact that the “smartest” people are filled with arrogance and hubris, but are not actually very smart. Add that many innumerate Politics and English majors have flooded into a field that cries out for engineering calculations. Add too that groupthink and orthodoxy enforcement prevent anyone from pointing out obvious flaws. And then throw in a strong dose of religious zealotry that obstructs the intrusion of anything resembling critical thinking. All in all, it’s a prescription for catastrophe.

But in a field rife with bad, worse, still worse, and even dangerously incompetent work, I don’t know if I’ve ever seen anything as shockingly inept as the Report just out from the International Energy Agency with the title “Batteries and Secure Energy Transitions.” The Report has a date only specified to the month of “April 2024,” but the press release came out just two days ago on April 25.

If I had been given the assignment by the North Koreans to write the Report to somehow induce the West to self-destruct, I don’t know how I would have done it differently.

Are you familiar with the International Energy Agency? It is not part of the UN, but rather a separate consortium currently of some 40+ countries, mostly Western and mostly rich, founded in the wake of the oil shocks of the 1970s with a then-goal of promoting energy security. It is based, of course, in Paris. The current (and since 2015) head is a guy named Fatih Barol. Here is a picture of Barol from Wikipedia:

Somewhere along the line the IEA completely lost track of the energy security mission, and turned into an unabashed advocate for the green energy transition. That’s where they are today.

I don’t know how many people work at the IEA, but it seems like most to all of them got in on writing this Report. On page 5 there is a list of some 35 “directors,” “lead authors,” and “principal authors” from among IEA employees, plus another 4 who provided “support,” and then, on pages 6 to 8, some 89 people said to be “high-level government representatives and international experts from outside of the IEA” who somehow “contributed to the process.” From the content of the Report, one has to wonder if any of these people ever completed the study of arithmetic at the sixth-grade level, let alone if any have read any of the important work in this area.

The thesis of the Report is that batteries, and particularly lithium ion batteries, are the key to the impending energy transition, and need to be scaled up massively and immediately with whatever amount of government subsidies and handouts that it takes. Here are a few quotes from the press release:

After their deployment in the power sector more than doubled last year, batteries need to lead a sixfold increase in global energy storage to enable the world to meet 2030 targets. . . . In the first comprehensive analysis of the entire battery ecosystem, the IEA’s Special Report on Batteries and Secure Energy Transitions sets out the role that batteries can play alongside renewables as a competitive, secure and sustainable alternative to electricity generation from fossil fuels. . . . IEA Executive Director Fatih Birol [said,] “Batteries will provide the foundations in both areas, playing an invaluable role in scaling up renewables and electrifying transport while delivering secure and sustainable energy for businesses and households.

I suppose it would be too much for me to expect these grandees to have read my energy storage report, published by the Global Warming Policy Foundation in December 2022. But if you are claiming that you have at hand a “competitive, secure and sustainable alternative to electricity generation from fossil fuels,” as these guys are, there is a series of very obvious question that must be addressed. Those include:

  • Quantitatively, how much energy storage, in watt-hours (or gigawatt-hours) will be necessary to provide full back-up to a national electricity grid once all fossil fuel back-up has been banished and the storage is all that is available when the instantaneous generators are not supplying the full demand?
  • How much will that amount of storage cost?
  • What is the maximum length of time that energy must be held in storage before it is called upon, and is the proposed storage technology capable of the task of storing energy for that period of time?

There are other comparably important questions, but at least those are absolutely essential.

The IEA Report addresses none of them.

What we get instead is endless happy talk about the wonders of lithium ion battery technology, how the costs are falling rapidly, how deployments are soaring, and how utopia (i.e., meeting UN COP 28 emissions reduction targets) is right around the corner if only we accelerate the process with massive government “support.” The full Report is some 159 pages (with appendices and references), so I can only give you a small sample. But here are a few choice quotes from the Executive Summary:

  • From page 11: “Batteries are an essential part of the global energy system today and the fastest growing energy technology on the market. Battery storage in the power sector was the fastest growing energy technology in 2023 that was commercially available, with deployment more than doubling year-on-year.”
  • Also from page 11: “Lithium-ion batteries dominate battery use due to recent cost reductions and performance improvements. Lithium-ion batteries have outclassed alternatives over the last decade, thanks to 90% cost reductions since 2010, higher energy densities and longer lifetimes.”
  • From page 12: “Policy support has given a boost for batteries deployment in many markets but the supply chain for batteries is very concentrated. Strong government support for the rollout of EVs and incentives for battery storage are expanding markets for batteries around the world.” [For the obtuse among the readership, “policy support” is code for vast subsidies and handouts.]
  • More from page 12: “Batteries are key to the transition away from fossil fuels and accelerate the pace of energy efficiency through electrification and greater use of renewables in power.”
  • Still on page 12: “To triple global renewable energy capacity by 2030 while maintaining electricity security, energy storage needs to increase six-times. To facilitate the rapid uptake of new solar PV and wind, global energy storage capacity increases to 1 500 GW by 2030 in the NZE Scenario, which meets the Paris Agreement target of limiting global average temperature increases to 1.5°C or less in 2100. Battery storage delivers 90% of that growth, rising 14-fold to 1200 GW by 2030.”

Check out that last bullet point. Yes, they are so dumb that they discuss energy storage capacity in GW rather than GWh. How did they come up with the line that to reach their goals “energy storage needs to increase six-times” when they don’t even know the right units to do the calculations? You won’t find an answer in this Report. In my own energy storage report, I calculated that to reach a zero-emissions electricity sector that could get through a year without fossil fuel back-up would require increasing energy storage by something around 10,000 times. I used the correct units and showed how my calculations were done.

And how about the question of the length of time that energy must remain in storage to back-up a wind/solar powered grid, and whether the proposed technology is up to the task? In my own report, which only considered scenarios of getting through a single year, I showed that much of the stored energy would need to be held for 6 – 12 months before use. In a further blog post on September 28, 2023, I covered a new report then out from the UK’s Royal Society (described by me as “semi-competent”), which used 37 years of data. Based on the 37 years of data, that report concluded that hundreds of hours worth of grid peak usage would need to be held in storage for multiple decades in order to get through worst-case sun and wind droughts. I had this quote from the Executive Summary of the Royal Society report:

Wind supply can vary over time scales of decades and tens of TWhs of very long-duration storage will be needed. The scale is over 1000 times that currently provided by pumped hydro in the UK, and far more than could conceivably be provided by conventional batteries.

(Emphasis mine.). I’m ready to forgive these IEA guys for not being familiar with my own report, but not for complete ignorance of the Royal Society’s effort.

The entire discussion that I can find in the IEA Report on the problem of need for massive amounts of very long duration storage consists of a chart and one paragraph of text on page 47. Here is the chart:

And the text:

Iron air and other battery technologies that potentially could enable the storage of electricity over longer durations measured in weeks, are still in their infancy. Currently it is not clear whether those technologies can be developed so as to provide what is required in a cost-efficient way. For even longer duration storage, such as seasonal storage, battery technologies are not fit for purpose, and other mechanical, e.g. pumped storage hydro, and chemical, e.g. hydrogen storage, technologies need to be deployed.

So 90 plus percent of the storage needed to back up the intermittently-supplied grid needs to be stored for months and years, but the only battery technologies that can even last for “weeks” are things that are “in their infancy” and where it is “not clear” that they can be provided in a “cost-efficient way.”

Overall, a shockingly inept and embarrassing piece of work from the IEA. Undoubtedly our government will react by piling forth a few more hundreds of billions of dollars to subsidize batteries to do a job for which they are completely “unsuitable.”

If the costs of batteries is going down so dramatically, how come the price of batteries for EVs have been going up in recent years?

Big improvements in battery performance? Where?
Can someone point to some actual numbers from real world batteries?

A simple estimate can be made by using the data available from the existing “Pumped Storage System.” That is size of the two reservoirs, Cost to develop Power consumed and generated. Salary of staff needed. Of the three I know of in the US all were designed for over night storage to supply the nearby city power loads for the power peak the next day and actually were a profit looser but necessary to maintain power. Cursory calculation shows that they can not provide 100% power for a full day. They alas are not suitable as a “Recreational” use lake, creating increased NIMBY attitude.

Francis I always enjoy your articles. As a retired electrical engineer engaged in power supply planning and economics for decades (and still consulting) I once respected the projections of the IEA. This latest report extinguishes any credibility that remained after pivoting about 15 years ago to become a superficial and cheesy cheerleader for the “green” renewable transition.

Thank you for your lucid dismantling of this effort to promote intermittent renewables through the unbridled fantasy of infeasible levels of battery installation, demonstrating that the IEA no longer concerns itself with even the most rudimentary numerate analysis, or collection of credible data.

One small point, his name is Birol, not Barol. I don’t want you to leave any target for IEA defenders!

Another factor rarely discussed when trying to figure how many batteries are going to be needed to provide backup, is system efficiency.
Most of these so called reports assume that if you put 100GWh into a battery, you will get 100GWh out of the battery. In most cases, when you factor in the losses in the converters that take AC and make it DC, then take DC and make it AC, plus the charging and discharging losses in the batteries themselves, you will be lucky to get 90GWh back.
And that’s before you add in the distribution losses from getting the power from where it is generated to the battery farm, then the losses getting the recovered power from the battery farm to wherever it is needed.

You could try to co-locate the battery farm with the wind and solar farms.
To avoid wasting land, you would have to place solar panels on top of the battery facilities.
Of course that makes the panels more difficult (and hence more costly) to clean and maintain. You also run the risk of burning up some of your solar panels everytime a battery decides to self immolate.

There is probably enough room in a wind farm to put these batteries. Though you do have to factor in that the batteries will on average make the ground rougher, which will have a negative impact on how much wind each tower is able to generate. Also you have to make sure that the blades of the individual turbines is far enough away from the battery assemblages that the heat from any fires doesn’t damage the blades.

Add in the power loss/inefficiency of AC transformers and you get an even lower number plus the I^2xR losses in the transmission lines.

A few of the activist “analysts” behind this fraud may be deluded, but overall they are pursuing an efficient strategy for achieving their actual goal, which is the total destruction of capitalism and freedom. As a particular example, they are trying to force everybody to buy EV, while making sure to block any and all of the infrastructure build-out that would be necessary to charge them. This is obviously just a scheme for achieving the eco-left’s long stated goal of eliminating the automobile. Multiply times 1000.

I don’t know how much the US pays to fund this outfit but we need to stop all payments to them.

Long term storage to batteries doesn’t make sense, that is true.
But short term storage to batteries for households makes a lot of sense now.
More than 2 years ago I built small hybrid solar system for my house, 3,4kW of panels and 5kWh LFP battery.
This system is able to provide 75% of my electric energy needs in rough central European weather, where is very little of production during winter months. My yearly energy consumption is 4.6MWh, 3.5MWh is now provided by solar.
Such small battery is able to take me through nights and smooth peaks in energy usage.
That means that solar intermittency is measured not in seconds, but in days. Giving grid time to respond with increased/decreased demand.
Now for same price I would be able to buy 16kWh battery.
this is 1.5 of my daily energy need. Such battery could take me through 2 bad solar days. Smoothing my energy consumption to 3 days. So only periods of bad solar weather longer than 2 days would bring need to connect grid energy.
This is putting no stress on grid, because it has a lot of time to respond on increasing demand.

You have a home with over 2600 square feet of south facing roof, and it only uses about 10.5 kWh of electricity a day? Less than 500 watts of power draw averaged over the whole 24 hour cycle?
I call BS on your ridiculous malarkey.
Hot water, lights, well pump, pool pump, TV, computers, cooking, cleaning, drying clothes…and the big one, air conditioning, which for a huge number of people in the US, is not a luxury, it is mandatory, for over half the year, 24/7, or you will have mildew on all your walls and furniture inside of two weeks.
A tiny space heater suitable to warm up a single little bathroom or bedroom, uses 1500 watts!
Nearly every item on my short list of power draws, uses substantially more than 500 watts, and your house sound over 5 times as large as mine.

Heating is provided with Natural Gas heater. I have AC capable to heat as heat pump. Which I’m using when I have surplus of electricity. This shortened my heating season from October – May to November – January.
Your math is little off, I wrote that my energy consumption is 4.6 MWh, that is 12.6kwh per day.
One third of roof on my house is not heated garage.
House is two floors around 190m2 (roughly 2050 square feet) of living space.
Hot water is prepared with separate solar system with 2.7kW panels. 100% of hot water during summer, 50% during winter, 75% overall.
Cooking is done with Natural Gas stove, averaging 0.25m3 per day. This is around 2.5kWh per day, cold by easily provided by solar energy, but me and my wife are liking Natural Gas cooking more.
I have well insulated house, reconstructed 5 years ago. Triple pane windows, 10cm of insulation over my walls, 23cm of insulation on roof. This lowered my heating energy to 40%. No mildew in any conditions.
I have AC, using it during summers, but during summer I have such surplus of solar energy, that it is 100% covered with my production.
I designed system all by myself, recounted everything to be optimal, I can provide you all numbers if you want.
For example here are my numbers for last month April:
8.6kWh average per day gain from hot water solar system
15.2kWh average per day gain from electric solar system
2.7kWh average per day consumed from electric grid
0.5m3 average per day consumed Natural Gas, 0.25 is cooking, rest is heating water during overcast days. Equals around 2.5kWh+2.5kWh.

At first glance I thought the article was about the IAEA (International Atomic Energy Agency) with headquarters in Geneva and Vienna.Very familiar with that organization as they bought a lot of our software back in the 80’s and 90’s. These guys really understand long term energy storage!
