Guest essay by Eric Worrall

According to meteorologist and green activist Eric Holthaus, any minute now we’ll have the affordable magic batteries we need to make electric cars useful and renewable power reliable.

Batteries are key to clean energy — and they just got much cheaper
Clean energy future might be closer than we previously thought

APRIL 10, 2019 8:00AM (UTC)

In a little less than a year, the cost of lithium-ion batteries has fallen by 35 percent, according to a new Bloomberg New Energy Finance report. Cheaper batteries mean we can store more solar and wind power even when the sun isn’t shining or wind isn’t blowing. This is a major boost to renewables, helping them compete with fossil fuel-generated power, even without subsidies in some places, according to the report. Massive solar-plus-storage projects are already being built in places like Florida and California to replace natural gas, and many more are on the way.

Electric vehicles will become cheaper to own and operate than gas ones. In places like California, Texas, and Germany, electricity prices have occasionally dropped below zero — a sign that the grid wasn’t yet ready to handle the glut of renewable energy produced there. Now, more of that cheap power will be stored and passed on to consumers. This could be the moment when renewable energy starts to shut down fossil fuel for good.

I think this is wonderful news.

If Eric Holthaus is right, there is no longer any need whatsoever for government intervention in energy markets. Adam Smith’s invisible hand will ensure renewables prevail by virtue of their superior value, well ahead of Alexandria Ocasio Cortez’s 12 year deadline to save the world from climate change.

All we need is for power engineers and scientists to stop dragging their feet, and get on with building the magic batteries.

I asked basically the same question of liberals back in the days when oil was being projected at $200 per barrel. That question was/is: If you really believe that, then where are the energy or alternative energy stock holdings at the top of your portfolio? Of course the answer is a sheepish look because they are only playing juvenile debate games in the first place with no intention of betting real money of their own.

The same question / test also works during all other current event headlines of resource scarcity. Where is it in your own portfolio and why does it not dominate any portfolio when the premise is that no one is ever going to find anymore of the stuff, or substitute, or use technology to change the demand and supply profiles.

‘Cheaper batteries’

Cheaper than what?

‘mean we can store more solar and wind power even when the sun isn’t shining or wind isn’t blowing.’

The idea is to store solar and wind power when the sun IS shining or the wind IS blowing.

Cheaper than before doesn’t mean better than before. Lithium ion batteries are like methane digesters: a sound idea chemically, and OK if you nurse them continuously and keep everything in side without well-constrained limits. Outside those limits, they get sick and die, sometimes by explosion.

Grid storage capacity is better achieved by using large grid storage devices, not thousands or millions of tiny ones.

Just ask Panasonic about cheaper batteries. They’re strategically backing out of their partnership with Tesla at the so-called Gigafactory because the costs are too high. Panasonic is one of the biggest battery technology companies with years of experience. If they can’t do it then it is truly magical thinking to assume it is “just around the corner”.

I suspect that some of the reluctance on the part of Panasonic relates directly to the failing fortunes of Tesla. No point in building batteries if there are no vehicles to put them in.

I’m also a bit astounded at the push by the major manufacturers to dive headlong into battery powered vehicles. If anything Tesla has shown a dedicated but small group of owners. I suspect we are headed to a market full of product and a lack of customers. Time will tell but my money is staying in my pocket and in my gas tank.

They drive down the cost of the batteries by reducing the number of expensive materials used to manufacture them like precious metals.

This is turn makes it less economically attractive to recycle them.

Making the batteries cheaper and creates a bigger toxic waste disposal problem.

Cheaper batteries mean we can store more solar and wind power even when the sun isn’t shining or wind isn’t blowing.

LMAO. That’s entirely the wrong time to be trying to store solar and wind power, as there is no power to store (or do anything else with) when the sun isn’t shining and the wind isn’t blowing. The time to be storing that power is when the sun *is* shining and the wind *is* blowing.

This is a major boost to renewables, helping them compete with fossil fuel-generated power, even without subsidies

Excellent, so we can start scrapping the subsidies. Quick someone tell the government.

Electric vehicles will become cheaper to own and operate than gas ones

Cost to own and operate is only one factor.

Will they have the range or towing capacity? I don’t care how cheap it is to own and operate if I can only drive 5 miles before needing a charge (yes I know EV can go more than 5 miles between charges, the number is only for illustrative purposes) or if I routine use my vehicle for towing loads too heavy for an EV to handle.

Will they be able to fully charge up as quickly as an ICE tank can be filled? If I live in an 5th floor Apartment (and thus have no easy access to a home outlet) and have to rely on charging stations, it does me no good if I have to waste a hour or more of my time waiting at the charging station for my car to charge.

And those are just two factors that would cause someone to prefer a “more expensive” but more convenient ICE vehicle to a “less expensive” but also less convenient EV. Only when EVs are fully comparable to ICE will they be able to replace ICE.

However, the fact of the matter is ICE won the race with EV over a century ago. Electric cars actually pre-date the Internal Combustion Engine variety, but the market place choose the later for many of the same reasons that EVs remain a niche product that only has as much market share as it currently enjoys due to being propped up with government incentives.

It remains to be seen what the train wreck will look like with the EV demand swarm for batteries occurring at the same time power generation with batteries takes off. Here are the scenarios: 1) Either lithium supply increases smoothly to meet demand, or 2) EV sales do match the plans and sales fall back and harms battery suppliers, or 3) the power generation market runs ahead of EVs with better ROI from utility scale solar and pressures EV battery prices. Lithium supply additions can respond to all of these scenarios in the long run but its the cyclical swings in the short and medium run that causes financial train wrecks. Be careful out there.

What the author fails to consider is the fact that 3 gallons of fuel oil equals the KWH output of one Tesla battery. It is pretty easy to store one million gallons of fuel oil as a backup source. The number of batteries needed to store even the smallest part of the US electrical output is beyond practical. Add to that maximum battery life is about 10 years and one can see how impractical Lion battery storage is.

April 12, 2019 11:37 am

As a matter of fact sodium-sulfur batteries are much more promising for utility-scale storage, since they are much cheaper and have a longer life than li-ion. However the high operating temperature and weight makes them unsuitable for non-stationary use.

Well, not a lot really, but occasionally they do, and they are well-nigh impossible to put out once they have started to burn (“thermal runaway”).

However a lot of fires are started by physical damage to a cell, so a stationary battery is less likely to burn.

Battery cost isn’t the only problem. Volume, charge time, and weight are at least as significant.

However, progress will be made and at some time battery cost, charge time, weight and volume might make them competitive. But I think we are more than five years away. Five years is the production horizon for technologies that are already well known and in use in niche markets, not for technologies that aren’t even known yet.

I think there needs to be an increase of energy density of at least one order of magnitude, and a lifespan increase equal to that before battery technology becomes viable in support of intermittent generation by devices which themselves need to be more efficient at converting their low-density energy sources to electricity, in order to attain a successful market share and truly compete with legacy power production methods.

Eric is a jerk. Batteries STORE electricity, they do not generate electricity. Batteries scanot transform renewable power generatros into reliable power generators. There is no limit to the period of time thatreneables produce little or no power. And batteries can’t store very much electricity, either. Current li ion prices are roughly $200-$250 per kWhr as constructed. A typical nuclear plant can produce power at one gigawatt level.
So one hour’s worth of output would be 1,000 MWhrs, or 1,000,000 kWhrs. That means you need $200 million dollars worth of batteries for each hour’s worth of output you want to store. Wind/solar power can disappear for hours,days, even weeks. Estimated prices of molten salt nuclear power plants is about $2 1/2 billion for 1 gigawatt power output. If that money was used to buy batteries for a 1 gigawatt renewable generator, you could provide storage for 12 1/2 hours of power output. The molten reactor will last 60 years, the batteries less than 20. This makes zero economic sense. Or any kind of sense – if the batteries are used to replace absent renewable, then how is the storage going to be replenished when the renewable power reappears?

First you have to produce enought and a bit more energy for a given time period to supply the needs, and then you need the batteries to store the excess energy to periods when the turbines and solar panels produce less.
I suppose all turbine operators will install batteries in the turbines, so that they can deliver the needed power when needed. Such a turbine would be a break and should capture all the windturbine market.
What could be wrong?

April 12, 2019 2:13 pm

I like the part about electricity cost falling to less than zero. What the h*** does that mean. The windmill produces electricity and dollar bills float down to the ground. electricity can not cost less than zero. Even without considering capital and maintenance you still can’t get to less than zero.

Reply to  pmcvay
April 12, 2019 3:05 pm

He was somewhat correct on that one. Electricity prices, not costs, have fallen below zero when the wind is blowing and there is insufficient demand for electricity. Utilities in California, Denmark, and Germany have been forced to give away electricity to neighboring states (countries) or pay renewable energy producers not produce. Of course, when the wind dies, they purchase electricity from neighbors at premium prices. No surprise that large German utilities have lost billions of euros over the last ten years.

People like Holthaus are so idealistic, it clouds their vision, they want others to jump on the renewables train while they themselves keep on using fossil fuels as before, waiting for some miracle of batteries to come along. It will never happen.

“In places like California, Texas, and Germany, electricity prices have occasionally dropped below zero — a sign that the grid wasn’t yet ready to handle the glut of renewable energy produced there.”

I have to call up LADWP. They apparently owe me a rebate check! Last i checked the electric rates here on the left coast were 50% higher than the US national average and climbing every year. The only consolation is we pay less per kwh than Germany. Not as far along the moral evolutionary curve I suppose but trying to catch up.

Eventually it will become undeniable that worth-less-than-nothing wind and solar junk power is nothing but “grid poison” and should be “landfilled” (most of the material is non-recyclable). Combined cycle gas turbines now & small scale modular nuclear reactors phased in beginning in 2027(see NuScale SMR news). Brainwashed warmist’s aren’t ever going to stop hating “fossil fuels”. Our only hope is for them buying into an incremental phasing in of NuScale SMR’s as a replacement for wind/solar/bio-fuels as renewable production and investment credits expire.
If batteries experience a technological breakthrough and storage becomes economically feasible than the batteries should be installed at large base load generating stations for night charging when power demand is low. Expensive new technology batteries scattered among thousands of low output intermittent wind and solar farms? Surely we aren’t THAT stupid.

April 12, 2019 11:48 pm

Great ! Once I made a rough estimation. Yes, I took very pessimistic 25% fuel efficiency engines.

How much of Tesla automotive batteries could supply the minimum energy for an empty 747 flying from New York to Paris. Yes, no payload, just a ferry joyride. Only the trip fuel, no contingency, diversion, alternate and other reserves. Equally no winds, just A to B ignoring even the evil climb fuel flows.

It boiled to more than 500 tons of whatever powers the Tesla model S. Wow. That’s sure worth a “HEAVY” after the call sign.

So what gives ? Well… Mid air refueling.

Depleted batteries would be jettisoned and land, like guided ordnance in selected areas. They could also deploy RAT’s (propeller driven generators) and use them to windmill and partially recharge on their way down.

Fresh recharged batteries would be fired as hydrogen powered rockets and lodge in specifically adapted orifices in the aft portion of the fuselage.

It’s all a matter of synchronism, charged batteries need to be fired in advance and penetrate the fuselage at the moment depleted ones are jettisoned.

Over the oceans, large solar powered barges could generate the electricity to recharge the ejected batteries and produce enough hydrogen to refill their rocket engines.

Yeah, see, electric commercial long haul flights are just a few technicalities away …

You are unduly pessimistic. Using the best theoretically possible batteries (Lithium-Air) with assumed near perfect efficiency, motors with a better efficiency than the best existing today, and propellers dito, and aerodynamics at least as good as the best possible today, I calculate it might just be possible for a really big (much larger than a ’747) aircraft to cross the Atlantic from Portugal to New Foundland by landing for re-charging on the Azores.

Of course with minimal reserves and no headwinds.

In other words, someday we might just possibly have electric aircraft with performance comparable to what conventional aircraft had in 1919.

What would happen if you took a Properly Functioning Human Animal (as evolved, defined & created by Ma Nature) and *did* switch off large parts of its thinking processes & memory – what would you be left with?
I’d assert just the very things you were born with. IOW = A return to early childhood

Someone behaving and talking like Hothaus is here – and in his previous F word outburst recently?

(Did he in ANY way get censured for that – his (childish) outburst makes Marie Antoinette look positively saintly. Patently not as here he is raving away soon after. Also, don’t children imagine themselves ‘so very clever’ when they start to learn Bad Language?)

Process & memory *do* get switched off – projections say that 50% of all Death Certificates in 30 years time will have the word ‘dementia’ writ upon them.

Yet Hothaus’ thinking is akin to many others now = i.e. that the use of Neodymium in wind turbines (and EV motors) is essential. We saw that even here recently – even skepticism is going down the pan.

No no no. Neo is used where you need a lot of magnetism in a tiny space.
Wind turbines are ‘tiny’??
Every motor car on this planet has a self-excited alternator bolted to its engine = No Permanent Magnet. Solid proven reliable technology, why not use that – even *before* we recall how old Windmill Technology actually is.

For EV motors:
When I was at Uni in Leeds, my Dept, (= Electrical & Electronic Engineering) was playing with switched reluctance motors. Totally no permanent magnet at all.

Problem in the 70’s was with finding the high speed switches *and* A Controller.
MOSFETs, IGBJTs and Raspberry Pi fixed that.

Elon is playing with switched reluctance motors seemingly.
See one soon near you in a moving car-crash or flaming-wreck.
Some folks call them ‘Teslas”

So it is with Lithium. Used to create compact & high density sources of power.
Nowden, 10% of Earth surface is entirely = wasteland (desert)
If you want batteries, put them there – totally No Requirement for any space-saving attributes.
=No Lithium Requirement
How will Eric take that?
(I think we can guess – wear a bullet-proof vest if you do try telling him)

If you do want battery, use a Flow Battery or Nickel-Iron
Esp Ni/Fe =solid, proven, reliable, VERY long lived and tolerant of epic abuse.
(Maybe not short circuits as was talked about before round here but are *much* tougher than Li-Ion)

But those ‘old’ things don’t appeal to children. Do they?
The penny will drop eventually for Eric but, how much damage will his (and many others) wild ideas, foot stamping and tantrums have done meantime?

Peta I think one of the reasons that PMs are used in wind turbines is weight reduction. You would need a lot more iron on top of a long pole without them. I am sure that each additional pound up there increases the weight of the entire structure geometrically.

Chevron just made a 50 billion dollar bet Eric will be wrong .

” Electric vehicles will become cheaper to own and operate than gas ones. In places like California, Texas, and Germany, electricity prices have occasionally dropped below zero — a sign that the grid wasn’t yet ready to handle the glut of renewable energy produced there.”

In places like germany 330.000 households can’t pay the global highest energy bills:

and that is redistribution from the poverty-endangered to the wealthy:

the lower class has to give the last money to pay for the electricity bill.

The wealthy do not realize that something like electricity bill exists.
