Electric-Bus Inferno In Hanover-Germany…Explosive Fire Causes “Millions In Damages”

Reposted from the NoTricksZone

By P Gosselin on 11. June 2021

Just a day before EIKE reported on burning e-vehicles in China, the electric vehicle curse struck in Hanover, Germany.

See video here.

A fire at a bus depot in Hanover caused millions of euros in damage. According to fire fighters, the fire broke out on Saturday afternoon at the Üstra transport company where electric buses were parked,

According to Üstra spokesman Udo Iwannek, the fire caused damage running in the millions. Five e-buses, two hybrids and two combustion engines were destroyed, as were also the building and the charging station.

According to the European Institute for Climate and Energy (EIKE), Hanover’s administration wants to run only e-buses in the city center area by 2023 and is purchasing 50 new vehicles in a bid to reduce the air pollution.

E-buses have shown to catch fire very rapidly. For example, four shuttle buses in Guangxi, China, exploded into flames last month:

It’s really not a good idea to park e-buses close each other.

According to Jörn Künzle at Facebook:

Although fires can happen anywhere, they become critical and dangerous when e-vehicles are involved. An affected battery acts as a powerful fire accelerant due to a chain reaction and must also burn out completely, which can take as long as two days. In February, Kulmbach in Bavaria became the first German city to close underground garages to e-cars as a result.
Regardless of the many question marks behind e-mobility, the city of Hanover is pushing it by hook or by crook, and even more so under its Green mayor Belit Onay.
Numerous technical and practical problems associated with e-mobility are far from being satisfactorily solved. And anyone who is just a little bit familiar with the subject also knows that e-mobility is by no means as good as we are always led to believe, even from an environmental and “climate protection” point of view. And what’s particularly bad is that the left-wing green media are keeping quiet about the event.”

Looks like the design of the bus depot is going to have to be rethought. Probably more like an air force base where each aircraft is put into a hardened bunker surrounded by sandbags.

They could also use the heat coming off the burning busses to boil water and make electricity.. like a cogeneration plant and stay green. Need to think outside the box here.

Build the bus park underground and with a huge water reservoir above it. When a fire breaks out just dump the water into the bus park and come back in a week.

Think you missed a word there Charles = no

If they can’t fix blowing up buses three things might happen ,go back to diesel and or give every one a bike, ( thier preferred option, or electric trams, thinks steel and copper for the infrastructure.

Darned kid’s birthday balloons (they should use hydrogen if they want a real bday blast) it also requires a low pressure environment. How much energy is required to lower the tubes pressure? Of course tunneling costs and materials require energy as well. I have worked with both cryogenics and vacuum systems and I don’t believe hyper loop is feasible without dilithium crystals.

In the early days, cars were kept in a separate coach house, which was distant from the residence in case the car started a fire. Is that going to be the new norm, the detached garage? Are modern lots even big enough to do this?

I managed a logistics group at an aerospace and defense company and shipped instrumentation around the world. We were required to include a MSDS with any and every shipment which had a lithium battery.We shipped a lot of instrumentation and kept a stack of Li battery MSDS. I don’t know how an MSDS mitigates any fire hazard. We could ship vehicles with lead acid batteries without an MSDS but if the vehicle had any Lithium battery…. That was over a decade ago – perhaps requirements have changed.

The USPS used to have posters at the counter describing all the items you are not allowed to mail. Along with flammable liquids and explosives were lithium batteries. Is this still the case? Even a decade ago I wondered about this as I blithely mailed a smart phone with lithium battery to a friend. The things are everywhere today, in all kinds of electronics, even toys. Are we soon to start seeing an increase in fires directly attributable to these batteries?

I was working at FAA headquarters in 2013 (albeit in the Office of Commercial Space Transportation) when the long-suffering Boeing 787 NightmareDreamliner was grounded due to lithium battery fires in its Auxiliary Power Unit – one of the plane’s critical safety systems. Though Chief Engineer in Commercial Space, I received weekly briefings on aviation issues. This one was familiar to me; I had worked at ATK prior to going to FAA, and one of my assignments was on the Orion Launch Escape System Attitude Control Motor. The ACM used a lithium-ion battery pack power supply, one of which burned up during a test at the manufacturer’s facility in California. I was sent to oversee the failure investigation. I’ve been doing space launch failure investigations my entire career, and have never seen anything like this. There was no systematic approach, and every engineer and technician I spoke with at the time said the equivalent of “I dunno what caused it, but we’ll just change a few things until it works.”

I won’t fly until airlines do away with mask requirements. But I’ll never fly on a 787.

Just the other day we went through a nearly 6-kilometer tunnel in Northern Portugal. Two lanes of traffic in each direction barreling along at 100KPH+. A perfect potential for a serious accident, bad enough if confined to ICE vehicles but catastrophic if EVs are involved.

griff, in your example when the diesel bus caught fire they pulled the bus over and quickly extinguished the fire. When the e-bus caught fire it destroyed five e-buses, two hybrids and two combustion engines were destroyed, as were also the building and the charging station. Can you see the difference? If you can’t, reach down with both hands, grab your ears, and tug your head sharply in a downwards direction.

The issue Griff, is that diesel or gasoline engines can indeed catch fire but two separate things are needed 1) a leak of the fuel and 2) a source of ignition – usually external to the engine. In battery powered vehicles no leak is needed and the ignition source is internal to the battery (an internal short circuit) and is unpredictable.

Given the sizeable number of electrical connections between the individual LiCobalt units that comprise a given EV battery, it would require an infinitesimally small failure rate in the soldering of connections to avoid an inevitable electrical short and an ignition event. Have there been any formal quality control inspection reports of the failure rate of soldering of the individual LiCobalt units within EV batteries published by the battery manufacturers? Is this data known? Has anyone calculate the probability of an EV battery ignition event based on the failure rate of soldering between LiCobalt units?

Thank you for providing an actual reference griff.

I do note that it was the second fire for an apparently very poorly run charter bus company.

Being from the Las Vegas area, we are used to hearing about tour bus crashes due to break failures, bad tires, etc. It always seems that the associated bus company has had MANY safety issues in the past, just like the company in the report you linked to.

The bus/shuttle fires referenced in this article were NEW. No chance for the owners to have to mess them up.

So incompetent maintenance, or unsafe design and materials.

The green choice will probably be: “Lets do both, buy dangerous vehicles and maintain them badly. The government is giving us LOTS of money to be GREEN.. And lets park them where we have parked our ICE vehicles FOR YEARS and have NEVER had a problem, with no regard to the change in hazard.”

What could go wrong?

And when the new lithium busses burn and destroy the structural integrity of the beams above, WE GET A NEW BUILDING, hooray!! I was tired of that old dirty building anyway. And since we will be shut down for a while, I can get paid to sit at home for a couple more months, or maybe even a year more, my China Virus vacation extended, what splendid timing!!

I always try to look on the bright side.

Now calculate the percent of the total number of ICE vehicles that spontaneously catch fire vs. the percent of EVs that catch fire or have already caught fire, and consider how long ICE vehicles have been around vs. EVs. ICE vehicle fires are usually the result of poor maintenance or human error. EVs catch fire with nobody around or simply driving down the road.

The problem with an EV fire is that all the energy needed to drive the fire is coming from the battery. With conventional fires, if you separate the fuel from the oxygen, you can put it out.
With EV fires, the only way to put the out is take the energy out, faster than the fire is releasing it.

There are things in this world called ‘Insurance Scams’

There is in fact, wonder if was/is some sort of omen or premonition, barely 200 yards from my cottage, a sizable ‘wood recycling factory’
They bring on old wood from demolitions, old furniture and office fitments, pallets etc etc.

Initially it is put into a mile-high pile sitting outside then goes through some sort of munching machine that creates a second mile-high pile, also outside and next to the first pile.
At some point it goes into a very large building and plastic-wrapped bales of animal bedding come out.
They are then stacked into a mile-high pile.

During lockdown, things have been quiet ish, but the pile of plastic wrapped bales is now truly Himalayan in height and extent.
Patently the market for wood shavings and sawdust has evaporated.

Thus this morning, from about 06:00, a gentle pall of stinking smoke (the smell of burning MDF or laminate) covered my house and all the surrounding fields.
All day, a gentle stream of fire engines, each chock full of mask-wearing yet obviously very cheerful/happy firemen came and went – and now 11 hours later, continue to come and go.
The gentle yet all engulfing pall of smoke is exactly the same size as it was this morning

Someone here said about ‘Tendrils’ growing in the batteries.
I think the word is ‘Whiskers’ and they only apply to NiCd batteries.
(Briefly connecting an affected battery across a welder usually repairs them. Seriously – the big blast of amps blows away the whiskers and said recalcitrant battery comes back as good-as-new.)

Lithium batteries are affected by ‘Plating’ = where the Lithium ions cannot get through the membrane separator fast enough in very high or rapid-charge situations.
So the membrane blocks up and the internal resistance of the battery skyrockets, meaning all the energy you’re pushing in trying to charge it, gets turned into heat instead of ‘charge’

The thing has nowhere to go but Up In Smoke.

Like my recycling factory, next door, right now, all day and into the night by the looks of it

Ahhh, spontaneous combustion of improperly stored biomass. Building and maintaining such piles is an art but a couple of rules of thumb are keep them under 35′, maybe 70′ if they are loose-even-sized chips, monitor moisture content, insert temperature probes, profile the piles carefully to avoid sharp edges which create a chimney effect, and most importantly Do Not Leave Them Unattended For A Long Time.
Fighting a fire in such piles can easily be a multi-day effort since the hot spots are protected by the overburden redirecting the water. The best way is to remove the unburned material from the area with heavy equipment, also an art.

Many of the fossil fuel vehicle fires are caused by the electrical system. Several years ago I helped a lady whose car caught on fire.

It’s even being admitted on the Bloomberg Business channel that EV’s have no advantage on saving CO2 (carbon) as compared to ICE vehicles for the entire life cycle of the car(s), and may even be worse if the electricity is created with coal for EV’s. And that’s before accounting of recycling the battery. The only advantage that EV’s may have is reducing local air pollution/ozone in the dense city core of a large city. Although new cars are pretty clean for their exhaust in the West.

Asia/Africa is a different story with all the 2 stroke motorized ‘rickshaws’ of one variety or another or even old poorly maintained 4 cycle engines in everything from motorbike trikes to Jeepney’s, such as in Philippines. Can’t even breath there from the carbon monoxide and pollutants from 50 year old diesels puffing like black smokers.

Crony capitalism is where government takes money from those who work and uses it to promote projects that end up enriching politicians and their friends and relatives

Where’s the capitalism in that?

We called them trolley buses. Great! Quiet. No exhaust small.

But not without their problems . . . . Remember, the bus can only travel where the overhead wires have previously been installed. Want to change the route? You’re going to have to relocate the overhead wires.

Street closed due to any problem — no bus service. Car hits a pole and takes down the overhead wire — no bus service.

Hello Markl

Yes there are chemical suppression agents for lithium battery fires. They work on small batteries, and the suppression agent is horrifically expensive. I’m well aware of this as we have done some lithium battery work in my business. A single use dispenser for a battery around 4x the size used in laptops had a cost of well over US$2000.

I think when it comes to the larger batteries used in cars and buses, the practicality and expense make this material rather impractical.

Hi Wally – I would prefer the batteries not combust at all but reality sets in with the quantities we’re looking at. Anyone thinking the answer is to just stop making/selling them is naive. Many fire trucks already have the equipment to add chemicals to the hose. It’s not new as with some fires foam works better. There’s also a small and simple end of hose attachment for delivery that works well with car fires. Not sure where you’re getting your cost information but single use dispensers aren’t what I’m talking about, although in certain situations (airports, planes) would be preferable. No, I’m not shilling for them, I’m just tired of all the whining about LiIon fires when there’s an available solution 🙂

John Endicott
Reply to  markl

Yes there is a solution – not switching to them. There’s no need, we already have a viable transportation vehicle design that doesn’t have that particular problem (of spontaneously combust fires that are impossible to put out by normal means). That’s not naivety, it’s a simple matter of physics and reality. When you can invent an alternative that doesn’t cause more problems than the current one and doesn’t require subsidies or mandates to sell, then and only then should switching be a consideration. Build a better car and people will *want* to buy it without being bribed (subsidies) or forced (mandates) to do so.

Battery operated city buses seem like an expensive solution to a non-problem. What ever happened to trolleybuses and trams? Any vehicle operating on a fixed route can be powered by electricity from overhead wires.

Using batteries to get power from the electric grid to the wheels of a vehicle is wasteful of resources to make the batteries, and wasteful of energy due to losses in the charging-discharging cycle, plus the extra energy needed to carry the weight of the battery. Fully battery-electric vehicles only make “sense” if they need to go anywhere, e.g. private cars, taxis etc.

The argument is maybe even stronger for trains, which is why logical thought seems to have gone totally “off the rails” in my former home:

ELECTRIC SCHOOL BUS SYSTEMS NOT COST-EFFECTIVE IN NEW ENGLAND AND CANADA
https://www.windtaskforce.org/profiles/blogs/electric-bus-systems-likely-not-cost-effective-in-vermont-at

EXCERPT

Charging Electric Buses
 
Normal Operation at 32F and below: On cold/freezing days, an electric bus battery would use its own energy to heat itself, as needed, during parking and driving.
 
Charging at 32F and below: No charging of Li-ion batteries is permitted, unless at an extremely low current
 
Power Failure at 32F and below
On cold/freezing days, a multi-hour power failure could occur
Partially full batteries, connected to dead chargers, could empty themselves to prevent freezing.
Batteries would be irreversibly damaged, if power were restored, and charging would occur at -32F and below, unless at an extremely low current
As an alternative, buses could be towed to a warm garage, then charged.
Emergency diesel power facilities may be required, if a prolonged power outage.

https://batteryuniversity.com/learn/article/charging_at_high_and_low_temperatures
 
NOTE:
– Batteries have miscellaneous losses to provide electricity to operate various systems, similar to Tesla and other EVs  
– On cold/freezing days, an electric bus should be ready for service as soon as the driver enters the bus; cold children are waiting at pick up points
– On cold/freezing days, the driver would need at least 70% charge for his morning round, because travel would require more energy per mile; no one should risk having an electric bus run out of juice, with a busload of children, on cold/freezing days.

NOTE
If the battery temperature is less than 40F or more than 115F, it will use more kWh/mile
The higher efficiency range, charging and discharging, is 60F to 80F. 
Batteries have greater internal resistance at lower temperatures. 
Pro-bus folks often point to California regarding electric buses, but in New England, using electric buses to transport children would be a whole new ballgame, especially on colder days. See URLs
 
NOTE: Where would the electricity come from to charge and protect from cold, expensive batteries during extended electricity outages, due to multi-day, hot and cold weather events, with minimal wind and sun, as occur in California, Texas and New England?

Which basically means these busses would need to be parked in a Heated AND Air Conditions building, OR, the batteries/battery compartment be heated cooled. The bus yard for our school district is about half the size of the typical College Football Stadium parking lot. Exercise: how much would that building cost. Extra points, How much would heating and cooling it cost? Seems to me that even in the southern areas you would be strapped with massive cooling costs.

I also know, from personal experience, that these temperature limits must be followed. While locked down from COVID I had forgotten that one of my LiIon powered hand drills was in my car, in the garage that had at least two dozen days with temperatures well below -20 degrees F. When needing a drill for a home repair I found it there in the car. Needless to say it was dead. Not a single charge status light lit up. Plugging it in the charger gave me the “Defective” battery warning.

It is highly likely the bus batteries were charged at 32F or less during winter, which is an absolute no, no for LI-ion batteries.

That means IRREVERSIBLE damage was done to the batteries.
That damage includes growth of dendrites that can short circuit cells.
A fire can break out at any time.

If below 32F, tow the buses to a warm garage, THEN charge them AFTER they are warmed up.

All you EV folks out there, please take note, so you will not be surprised.

Could you build an electric heater for the batteries, and have the charging circuit first power the heater until the battery is warm enough, then start to switch some of the energy from the heater to battery charging?

This is how my 2021 Toyota RAV4 Prime Plug In Hybrid works. It has both A/C and heating elements (liquid cooled/heat) built into the battery compartment under the back seat and in the underbody of the vehicle where the batteries are. It works best if plugged in from shore power, but also works off the main traction battery stand alone until the battery voltages drops and then the hybrid 2.5 L Atkinson cycle ICE kicks in automatically and supplies both charging for the main battery and thermal heat from the gas engine if heating required in cold weather. Have to enable the auto engine start in case you park inside an attached garage to your house, so as the CO doesn’t do everyone in. I see a lawsuit coming for some of the auto features such as auto engine start, and gases everyone in the house.

EV batteries do have heating and cooling systems, usually heat pump driven. The electricity would be from the charge in the battery, when on the road, under normal circumstances.

However, if you parked it at an airport, etc., on a freezing day, and need to charge, you may drive to a charger, but DO NOT PLUG IT IN.

First you have the heat up the battery with whatever heat is available.

Call a Tesla road repair van. It will have a heater, etc.

It likely would take at least an hour to heat the battery above freezing, say 35F, THEN you could plug for charging.

NEVER, NEVER CHARGE AN EV AT 32F or below.

If you do, you will irreversibly damage the battery, because the lithium ions plated on the anode will be there forever. Your range will be mostly gone.

That might be the case for the buses in Hanover, where winters do get cold, but it’s not an explanation for the bus fire in Guanxi. Guanxi is subtropical at 25 degrees latitude, the same as Miami, Florida, and winter temperatures rarely hit freezing point or even near that. The risk of EV battery fires may be worse in colder regions, but it is an inherent risk everywhere.

The new buses will be built by Alexander Dennis at its manufacturing sites in Falkirk and Scarborough.

The transition requires a £35.6m investment by First with electric buses costing almost double the £225,000 bill for a single decker running on diesel.

The entire equation doesn’t work. In order to reduce the CO2 from diesel engines, they must produce more electricity from either fossil fuels or “renewables” which require even more wasted materials and energy. It’s a whole daisy chain of waste just to reduce CO2 in the end user. Overall, it increases CO2 output.

Only a socialist green moron could conceive of such madness. It is rather like China’s “great leap forward” producing “the people’s (low grade) steel” in village retorts out of “scrap” high grade steel. The steel wasn’t good for anything and they had scrapped otherwise useful steel equipment, in their zeal. Central planning rarely works.

He was concerned about the stories of laptops and Cellphone catching on fire so he purposely purchased LiIon batteries that were built for government use to very stringent government specifications on operable temperature range, amperage, use at high elevations, etc. for use with hi communications and GPS equipment. Even after taking all of these precautions, the second time he used it it caught on fire at about 10,000 feet. IMHO, These batterers are still not ready for prime time.

Wally
June 12, 2021 7:04 pm

A little technical information for you.

ALL (re)chargeable batteries use / have a chemical reaction in order to store power: the electricity used to charge is converted into chemical energy, and that conversion is never going to be 100% efficient. The energy going in that can’t be converted to chemical storage is turned into heat (this according to physics: the conversation of energy: what goes in must all go somewhere, and what’s not used for the intended process goes into something else and in almost everything, that is heat).

ALL (re)chargeable batteries also use / have a chemical reaction to extract the power. The chemical energy is converted back to electricity, and this process is also not 100% efficient. Therefore when discharging to extra power, some of the stored chemical energy is converted to heat.

These phenomena are easily measured, for example using a thermal camera, on batteries of any kind when they are being charged or discharged.

What matters with batteries is to ensure that the heating is kept within acceptable limits, because ALL (re)chargeable batteries have this thing called thermal runaway.

NOW, given the physics is understood due to the universe and materials being imperfect, the next thing to understand about all batteries is:

  • They store energy
  • That energy wants to go somewhere (this again, being entropy: laws of physics, which you can’t legislate out of existence)
  • Thermal runaway is a part of how batteries are.

Thermal runaway is what makes all batteries dangerous. This includes your old fashioned NiCd as well as the more modern Lithium.

To quality that: Some battery types are so robust that in practice you will never see this be an issue (for example, Lithium Ferro Phosphate); however they are not used in vehicle applications because their energy storage density is low.

High energy density = more storage in a given physical size, compared to a battery of a lower density. Nobody wants massive batteries, with their volume and weight, when smaller does the job more effectively.

The trade off is that high density is more prone to thermal runaway as well as other things like physical fragility.

The effect of thermal runaway is like a chain reaction:

  • Something happens to make a cell get hot (a battery being a collection of many cells) – this might be physical damage, charging too fast, environmental effects, manufacturing defect, or something else.
  • Discharging a battery too fast can equally cause a cell to get hot (recall from above: extracting energy is not 100% efficient, so cells get hot during discharge).
  • When the cell gets hot, and provided the fault condition is not removed, it continues getting hotter.
  • Once a threshold is reached, the cell suffers internal structure damage, and at that point the situation can’t be reversed: the cell continues to get hotter, the energy in the cell is being turned into heat. Eventually that heat causes case rupture, and so on.
  • A hot cell heats up the cells next to it.
  • The cells next to the one with the heating problem also begin heating, and once they reach that critical temperature they too have the same problem: even if they don’t have a fault inside of themselves and even if they are not being charged or discharged.
  • The cells next to the one that began the trouble go the same way, and the problem spreads, and as every cell has many cells nearby, this is not a linear speed in the spread, it’s exponential (1 causes many, and many cause many many more).
  • Once started the process can’t be stopped.

An energetic battery fire, once started, is pretty much all over in a matter of minutes.

The danger temperature is one deep inside the cell, not on the outside, and once exceeded it is like a tipping point: there is no return.

The reason these fires are so hard to put out is: you need to do 2 things to stop these kinds of fires:

  • Remove the fuel source; and
  • Remove the source of heat.

And the trouble is – the cells of the battery are BOTH the fuel source, and the source of heat. Removing both is very very difficult.

The modern suppression agents help a little, for small fires involving few cells.

For large fires, with hundreds or thousands of cells, in a battery bank under vehicle seats or floors, the difficulties associated with using any suppression system or modern material is the amount of suppression agent needed (and its prohibitive cost), and access in a timely manner to the place where the cells are located .

This all fits into the category of vexing problems. To some degree the issues can be managed using a lot of very good monitoring circuitry and having fail-safe systems shut off charge / discharge if temperatures get too high. Fundamentally, rechargable batteries are dangerous things and wishful thinking does not make them less dangerous.

I would never have a Lithium battery power wall or similar storage product mounted on my house, and never ever ever on an interior wall, not even in a garage. It’s only a matter of time before houses are destroyed by these things going up in flames.

As far as transport vehicles go – it would seem to be very early days. Perhaps one day the technology will improve.

Recall those photos of things like the Tesla giant battery farm built in South Australia? Now you know why there are many small huts, separate from each other.

I think Wellington in New Zealand replaced their fleet of electric trolley busses, which were great BTW, with e-busses and were a complete failure IIRC.

Heh… I’ve been perturbing to no end a climate kook over on CFACT who was bragging about his Tesla… claimed it was “over 90% efficient!”.

Except Lawrence Livermore National Laboratory and DOE show that the efficiency of the US grid system is 34.83%:

… the Tesla charger is rated at 92% efficiency at 240 V / 24 A and 94% efficiency at 240 V / 40A or 80A, the Tesla battery has a maximum efficiency (energy in:energy out) of 90% and minimum of 80% (dependent upon age and use), and the Tesla vehicle has an overall drivetrain efficiency of 93%.

That gives a ‘fuel to wheels’ efficiency of:
100 * .3483 * 0.94 * 0.9 * 0.93 = 27.1088856% “fuel to wheels” efficiency, which is comparable to an ICE-powered vehicle.

So when charging his 100 kWh battery, assuming charging from 50%, he’s burning 184.4414 kWh worth of fuel, assuming maximum efficiency all along the line.

Now, he lives in Illinois, where 27.3% of electricity is generated by coal-fired plants, meaning that 50.3525 kWh worth of his energy is coming from coal… he’s essentially driving a 100% coal-powered car, and burning an additional 134.0889 kWh worth of fuel from other sources just for the fun of it.

He hates it. LOL

That, combined with my warning him not to park his vehicle in the garage or charge it in the garage, while showing him story after story after story of vehicles that have burst into violent flames in a matter of seconds (just as we saw for those buses), burning the structure as well… well, it’s got him feeling blue and more than a little paranoid about his coal-powered fire trap vehicle. LOL

Nice analysis

On the same A-to-Z basis, IC vehicles are about 20% efficient

You have to go from oil well to wheel, or from coal mine to wheel, or from forest to wheel, etc

Regarding EVs, for moderate climates, about 17 to 18 percent is lost due to charging the batteries, and running various ON BOARD systems at the same time.

For cold climates, charging is slower, less efficient and ON BOARD uses more.

If you want long battery life with minimal degradation, operate between 20% charge and 80% charge at all times; it is most efficient. Use a regular IC car for long trips.

How do we know an e-bus can’t catch fire when in use?

Electric trains work because they are fed electricity and don’t have batteries. Battery powered airliners opens up a bigger can of worms (imagine).

No sane airline is going to pay the costs for hauling the dead mass of a huge battery from city-to-city.

E buses are not a good idea. FTFY.
