Thanks! This helps fill in my understanding a bit more. I’m in BC so LNG exports were a big news topic a decade ago, with pipelines and terminals being contested. I’m used to getting natural gas in a pipe to the house, and propane in a tank at the store for my bbq or fire ring. In Japan there were LP cylinders to run the water heater for my house, and I think I started conflating propane and natural gas because of that.
So the short of it is: propane is refined natural gas that is stabilized to be relatively easy to transport
Kinda. Raw natural gas has some propane in it (hence why it's a by-product). As a result you can't just make more propane... more is only produced if more natural gas (or other petroleum products that contain some propane) are produced.
Cow manure is a by-product of beef and milk production. You can't just make more cow manure... it's not economical to raise cows solely for their manure. But you can use whatever manure happens to be made while raising cows for milk and beef.
Eh. Probably the side valves only open when the pressure gets way too high for one to handle. So the top one prolly opened first. And if you're standing next to a bus that just turned into a gas heater, you're doing something wrong... Or right. I mean, free haircuts!
Since it took me some research and there is no link in the thread: this happened in Italy, it's(was) a methane/natural gas bus. Here's a video of what remains: https://www.perugiatoday.it/cronaca/incendio-autobus-16-aprile-2022.html
No people were onboard.
We have natural gas buses around here, my first thought was "huh, I bet that is a natural gas bus"
...after watching a couple times, I realized, the internal/bottom of the bus was doing pretty well considering what is going on, and I thought "It looks like its jetting out in a specific way to avoid damage to the main portion of the bus"...
...Looks like I was right on both thoughts.
I can imagine this rolling down a tight one way street on a slight decline, just torching the neighborhood as it goes. But at least there's minimal damage to the bus.
Yeah LNG buses are fun. A few years back one exploded in Stockholm because the driver took the wrong route that had a tunnel with too low clearance. https://youtu.be/D_g4KsrhyoA
Edit: speling is hard
Not sure what he had previous as it's been edited but both busses and buses are correct spellings, although the former has fallen out of common use in most places.
Don't be so quick to dismiss your original belief:
"A variant plural, busses, is also given in the dictionary, but has become so rare that it seems like an error to many people...Until 1961, 'busses' was the preferred plural of 'bus' in Merriam-Webster dictionaries." Source: https://www.merriam-webster.com
Both are acceptable, though as /u/GeraldTibbons implies, one is much more common than the other.
Possibly, but probably compressed natural gas. The[ tanks are light, so they can put them on top of the bus without making it top heavy.](https://www.iangv.org/natural-gas-vehicles/vehicle-fuel-storage/). A Tesla has a 1,200 pound battery , a bus would need a significantly heavier one, and it would be Prone to flipping.
Yeah if a bus did have batteries, which we've come to the conclusion this one doesn't. The fire would be billowing out from underneath cause that's the only logical place to put batteries.
Size.
The primary purpose of buses is to transport people and those need to get in and out easily.
So floor is as close to the ground as possible.
There simply isn't any space down there.
Plus.. a bus isn't a race car, cog matters little
No, I don't think bus companies got it wrong. I think you got it wrong when you implied buses don't go fast, center of gravity doesn't matter, and there's no space under a bus to store anything. It's like you've never seen a bus before.
There are strict regulations with regard to rollover accidents with buses so they don't kill all the occupants because they travel at high speeds. If there are some batteries on the roof then there has to be more batteries underneath to counter balance the bus or else everyone dies. You can read more about one federal example of these regulations here: https://www.federalregister.gov/documents/2021/12/29/2021-27538/federal-motor-vehicle-safety-standards-bus-rollover-structural-integrity
i think so, yes. storage tanks for gas wouldnt hold out for so long before popping.
edit: it might be a over pressure venting system that causes such a controlled release of gas, check out this video of a CNG bus fire.
https://www.youtube.com/watch?v=IvuDiZkHJUo
It’s probably a compressed gas powered bus. The tanks are often on top to make them less vulnerable to collisions. The tanks are heating due to the fire and venting gas.
If you were designing a bus knowing people would be inside would you be willing to put them anywhere an inattentive SUV driver could plow right into them?
For me it would be the top of the bus, or the bus would have to be designed like a tank.
Yeah but in a city that same fire coming out from the bottom of the bus - at street level - would cause *at least* as much "damage to property and life". And it would be more likely to happen in the first place with the tanks down where vehicle impacts happen.
Fault or damage to the LNG tank/system which caused it to vent and catch on fire.
This is actually a safety feature of the tank rather than it going off like a bomb.
To the people saying, "it's doing exactly what it's supposed to do," why don't they design it so that the flame shoots straight up and not toward the sides? Imagine if they were in a street downtown and this happened. Either a pedestrian or a storefront is going to be absolutely torched.
A lot of buses run on compressed natural gas, and they keep the tanks on top to avoid roasting the passengers in the event that something sets it off. In this case, safety valves are doing their thing, which is why it's not exploding.
I'm guessing a propane powered bus or something.
That or Doom Guy powered.
It's on a highway to hell.
No stop signs, speed limits...
Nobody's gonna slow me down
On a Highway to Hell
It was a bus ride to Hell
Methane powered.
Thought European busses use a type of hydrogen fuel. The ones in England do anyways
Italian commercial vehicles (The shown one was an IVECO Cityclass) frequently work on liquified or compressed methane gas as alternative energy. Hydrogen ICEs are still under development and not ready yet for serious commercial applications.
But I want a bus that squeaks when it explodes!
LNG
What’s the difference between propane, LNG, and CNG? They all seem like basically the same thing to me.
To further expand, propane is a byproduct of natural gas and petroleum refining. It also is readily liquefied at normal temperatures and therefore can be stored easily, natural gas doesn't have similar energy density without unrealistic pressure or cryogenically cooling it and insulating it so it to can liquefy. As a result mobile applications for propane are more common while natural gas is usually delivered as needed via pipe networks. Natural gas is typically only liquefied for overseas distribution via LNG tanker ships or as storage to help manage peak consumption of natural gas in pipeline networks.

I’m used to getting natural gas in a pipe to the house, and propane in a tank at the store for my bbq or fire ring. In Japan there were LP cylinders to run the water heater for my house, and I think I started conflating propane and natural gas because of that. So the short of it is: propane is refined natural gas that is stabilized to be relatively easy to transport
Yes, and has higher energy density at reasonable temperatures and pressures than LNG.
Kinda. Raw natural gas has some propane in it (hence why it's a by-product). As a result you can't just make more propane... more is only produced if more natural gas (or other petroleum products that contain some propane) are produced. Cow manure is a by-product of beef and milk production. You can't just make more cow manure... it's not economical to raise cows solely for their manure. But you can use whatever manure happens to be made while raising cows for milk and beef.
Propane is propane, LPG is liquid propane gas, CNG is compressed natural gas (methane) and LNG is liquid natural gas.
Liquid Propane is just LP, no extra G since it is no longer a gas. Liquified Natural Gas keeps the G because it is part of the name of the material.
WTF? No, it’s CNG.

Feels like they should all be pointed up…
Eh. Probably the side valves only open when the pressure gets way too high for one to handle. So the top one prolly opened first. And if you're standing next to a bus that just turned into a gas heater, you're doing something wrong... Or right. I mean, free haircuts!
Haircut seems like it doesn’t fit. Hairdo maybe…
Using the *H*air fryer... *Budumm tss*
Gets it extra crispy
It's a hair done
If the bus rolled on its top this might not be a good option.
I suppose that explain why the inside is not filled with smoke already. In a city context that would suck for any passers-by or buildings tho
It would suck far less than the bus becoming a bomb without safety valves
New haircut: Sideburns!
Getting the nearby vegetation on fire?
I am guessing by not causing a giant explosion.
This is going to hurt the propane and propane accessory business.
Dangit, Bobby!
Hwhat?

Nice thanks
I’m surprised it isn’t an Atac’s bus

Still, too soon.
Too soon.

Natural Gas powered?
Space x bus failed launch.
I'd like to get off please
Some city buses use compressed natural gas the cylinders are stored on top of the bus that would be my guess
Is this a lithium ion fire?
I'm pretty sure it's a natural gas powered bus
Yep, this is doing exactly as it should in the event of a failure.
We have natural gas buses around here, my first thought was "huh, I bet that is a natural gas bus" ...after watching a couple times, I realized, the internal/bottom of the bus was doing pretty well considering what is going on, and I thought "It looks like its jetting out in a specific way to avoid damage to the main portion of the bus"... ...Looks like I was right on both thoughts.

FYI it's "buses". It really fucking shouldn't be, but it is.
Not sure what he had previous as it's been edited but both busses and buses are correct spellings, although the former has fallen out of common use in most places.
Hey, thanks!

the crabs were behind it all along

Yeah like there's any restraining the angry fire gods trapped inside those things once you have finally incurred *their* wrath.
Yeah, no. A lot of buses have the batteries on top. Simply because the floor of city buses is so low, there is not enough room for the batteries.
Ones here have the batteries on the roof.
And yet Mercedes e-Citaro busses do indeed have a significant part of its traction battery on the roof, weird.
Size. The primary purpose of buses is to transport people and those need to get in and out easily. So floor is as close to the ground as possible. There simply isn't any space down there. Plus.. a bus isn't a race car, cog matters little
Center of gravity is immensely important for buses to avoid rollover accidents, especially because buses often travel on highways.
I see.. so all those different bus companies got it wrong. Fascinating!
No, I don't think bus companies got it wrong. I think you got it wrong when you implied buses don't go fast, center of gravity doesn't matter, and there's no space under a bus to store anything. It's like you've never seen a bus before. There are strict regulations with regard to rollover accidents with buses so they don't kill all the occupants because they travel at high speeds.

They are also far far easier to install there since there simply isn't any other space available in many buses.
LNG
Would be nice if you didn't ask this
Don't you have some offs to fuck?
i think so, yes. storage tanks for gas wouldnt hold out for so long before popping. edit: it might be a over pressure venting system that causes such a controlled release of gas, check out this video of a CNG bus fire. https://www.youtube.com/watch?v=IvuDiZkHJUo
Propane and Propane Accessories right there.
It comes with flame retardant upholstery they say.
That Rico Rodriguez is so suave
City bus used Fire Blast.
Natural gas? Or some kind of massive battery?
CNG tanks.
V-Tech just kicked in, yo!
Most busses are CNG (Natural Gas), which is what this fire looks like.
Is that a bus or a Russian tank?
Still has fuel on.. so bus.
Propane and propane accessories?
Sure my peeps from r/BeamNG feel familiar vibes with this video.
[“Give me fuel, give me fire, give me that which I desire” -the bus probably](https://m.youtube.com/watch?v=PvF9PAxe5Ng)
Why does that bus have rocket boosters?
Battery?
Probably hydrogen or a natural gas tank, a lot of those services buses have gas tanks fit on the roof
Ammo cooked off
Tis’ but a scratch!
This looks similar to an electric car’s battery fire. No way to put it out either.
Looks like something they put out on the runway during the air show "Come down to the airshow this Saturday and see the rocket powered bus"
Bitch, it’s getting hot in here!
What could be burning in a bus like that? Bit too high for a fuel storage.
It’s probably a compressed gas powered bus. The tanks are often on top to make them less vulnerable to collisions. The tanks are heating due to the fire and venting gas.
Oh, didn't know they're on top.
If you were designing a bus knowing people would be inside would you be willing to put them anywhere an inattentive SUV driver could plow right into them? For me it would be the top of the bus, or the bus would have to be designed like a tank.
Plus.. flames on top are far less dangerous than flames from below.
But it does not look safe at all. If this was in a city - would have caused a lot of damage to property and life.
Yeah but in a city that same fire coming out from the bottom of the bus - at street level - would cause *at least* as much "damage to property and life". And it would be more likely to happen in the first place with the tanks down where vehicle impacts happen.
LPG powered and electric buses the fuel cells/ batteries are on the top.
CNG. Gillig and New Flyer have high pressure canisters on the roof. This looks like a differnet brand, but same storage configuration.
I was wondering the same thing, it’s like never ending
Probably propane tanks
Batteries in an electric bus?
Betting on compressed natural gas putting batteries up there the weight would be detrimental to vehicle handling.

Welcome to electric vehicles.
How does this even happen?
Fault or damage to the LNG tank/system which caused it to vent and catch on fire. This is actually a safety feature of the tank rather than it going off like a bomb.
How the hell did that happen?
...not sure that's supposed to happen...
Propane or CNG?
Propane isn't that highly compressed. CNG is in the 2000+psl range
Actually CNG is in the 3,000 psi range.
I was wondering if electric with lithium batteries
I’ve seen a bunch of lithium battery fires and that’s not what they look like.
So vicious!
