California firefighters had to douse a flaming battery in a Tesla Semi with about 50,000 gallons (190,000 liters) of water to extinguish flames after a crash, the National Transportation Safety Board said Thursday.

In addition to the huge amount of water, firefighters used an aircraft to drop fire retardant on the “immediate area” of the electric truck as a precautionary measure, the agency said in a preliminary report.

Firefighters said previously that the battery reached temperatures of 1,000 degrees Fahrenheit (540 Celsius) while it was in flames.

The NTSB sent investigators to the Aug. 19 crash along Interstate 80 near Emigrant Gap, about 70 miles (113 kilometers) northeast of Sacramento. The agency said it would look into fire risks posed by the truck’s large lithium-ion battery.

    Firefighter here. Sometimes a better and less harmful option is to let things burn and protect the area. I went to a semi wreck that was hauling diesel and on fire on its side in the grassy median about 100’ away from a storm drain. Trying to put that out with just water would have become an environmental nightmare if all that fuel would have gotten washed into the storm system.

        My primary is a prius and I’ve done auto work and tech repairs for like 25 years now.

        I’m not buying an all electric EV, yet. They’re still wasteful and heavy and the battery tech isn’t quite good enough. EV’s pretty much have a life of 15 years on them (after going through tires faster) and then off to the junkyard once the battery goes out. I have high hopes for the solid state batts from Samsung hitting some production EV’s in 2027, though. Lighter, faster to charge, and longer lifespans. Until that, I’m sticking to hybrids, where the battery is less than 100 pounds, cost a few grand instead of $15,000 and you can swap one out at home in an afternoon with no special/expensive equipment.

    I went through “Bedrijfshulpverlening” (Dutch, if you want to run it through translate just in case I mess up the correct translation). I guess it’s business first responder or something.

    When we were attending the fire training part and we were teached about fires, someone asked “what if there is a car fire”. They said: “starting petrol car fires can be extinguished with a portable extinguisher if you are lucky. But electric car fires, leave them alone. They seal the cars in special water-filled containers and leave them alone for two weeks. There are reports that even after the two weeks, when the car was retrieved from the water, the fire started again on it’s own. Firefighters really hate electric vehicles”.

      "alright, is everyone here? this is an all-hands meeting. Where is Joey? Is he in the bathroom again? He’s missed the last 3 meetings… Anyway. Top of the agenda, there’s apparently a fire, right over there. Fires are kinda hot and so we have been sure to stay a good distance away, as to not raise the temperature of everyone’s complimentary bottled water, handed out at this meeting.

      Now it says here that we should tackle this situation as quickly as possible. Has anyone run the numbers by the finance team? We don’t want to spend too much on this. The big-wigs upstairs never think about the big picture, and really I don’t see why one fire is worth pivoting all our available resources. Samantha, yes?"

      “Sir, the fire is growing at an alarming rate, shouldn’t we just postpone the meeting and focus on the fire?”

      “See, that’s exactly the kind of thinking the execs have. But if we spend all our resources, cuts will be made, and jobs will be lost. Not mine, of course, but others. Did anyone do a PR analysis on us ‘putting out this fire’ versus just running a week-long ‘we are sorry’ ad campaign?”

        Lithium isn’t just a metal it’s a metal that has a rapid exothermic reaction with water. Or at least that’s what I remember my high school Chem teacher saying.

          You are right, but in the case of a Lithium battery fire the strategy is to use the large thermal capacity of water to cool the battery until the reaction is done.

          I just remembered i can even name myself as a source when i fucked up and punctured my phone battery while disassembling it (those dumbasses used large amounts of adhesives to mount the battery and i wasn’t careful enough). I simply dropped it into a bucket of water and waited it out.

            Pure sodium can react with the moisture in the air. (If I recall correctly).

            Aluminium is used in drink cans and is very inert. Aluminium shavings can burn though and they’re difficult to extinguish.

              Pure elemental aluminum isn’t stable. The aluminum used in cans and such is an alloy and not pure elemental aluminum. My chemistry teacher blew a hole in the ceiling tiles of the classroom when he showed this off. The sodium didn’t react nearly as violently (but he also used a much smaller chunk).

                aluminum is stable in the sense that the outer layer oxidizes rapidly and prevents the rest of the metal from reacting with anything. the reason thermite is so exothermic is because of massive amount of surface area provide by the powdered metal. a chunk of aluminum simply isn’t dangerous.

      Depends on the chemical, but it is an appropriate way to fight a liion battery fire though.

      You’re fighting thermal runaway. Water is very effective at cooling and helps control the fire and keep the heat down. US DOT recommends water spray.

      Maybe. Water is cheap, available in quantity, and non-polluting. Since a battery fire is self-oxygenating, I don’t think putting it out is something you expect. All you can do is take away the heat both to contain the damage and to eventually stop the reaction.

        And water has great heat capacity, with a nice phase change, too.

        From reading other links in this post, it sounds like pollution (runoff) is a concern, which is unfortunate.

        But it the most available and least toxic fire suppression, especially on a highway.

        Foam is full of PFAS, etc and the cost (in CO2 and money) of air dropping, and having to wash the foam off the highway afterwards - leading to runoff - is huge.

        Imagine that happening 100 times per day on American highways (when electric trucks become commonly used).

                Nnnno, I’m sorry, you’ve misunderstood - I was airing my (fairly reasonable) doubt that you don’t know why it shouldn’t be used on those types of fires.

                It is, I admit, also not my responsibility to educate those too stupid to google stuff, but just for fun: Electrocution risk, grease fires explode when doused with water, unknown chemicals may interact with water unpredictably.

                Water is absolutely used to combat battery fires. It won’t extinguish them, but since firefighting is more complicated than “it puts the water on the flames or else it gets the hose again”, that’s not really the goal. It’s to keep the chassis/batteries cool, douse the surrounding area to prevent the fire from spreading and keep any toxic combustion products from spreading via smoke (yes, that means they get washed into the environment. Not ideal, but better than breathing it.)

    Remember that non electric cars are still dangerous too. Just think about how often you see a wreck that has cops, firetrucks, and cops all around it. That isn’t going to make the same level of national attention as an electric car burning would get.

    There are a lot of reasons WHY news agencies disproportunatly show the downsides of green energy, and I’m hardly scratching the surface, but here’s my personal reasoning:
    News sites like to over dramatize green energy dangers as they are funded by fossil fuel companies (ads). Theres a large amount of disinformation that they misleadingly tell people, take for example birds running Into windmills is something a LARGE amount of people know and think is an issue. However, statistically fossil fuels cause ~50x (iirc) more bird deaths per unit of energy than windmills due to birds being an apex preditor. Another example is that nuclear waste is a big issue that will prevent nuclear energy from becoming superior when that issue was solved several decades ago.

    Yes, elon sucks and some of his practices should be banned, but it’s still green energy and you can’t let it distract you from the benefits of all electric vehicles.

      Electric cars are not “green energy” - that’s utter bullshit.

      1. the energy consumption of electric cars is about as clean as the power plant that produced said energy - if that happens to be a fossil fuel plant, it’s dirty as fuck, just with the pollution in a different location from where the car is driving If you have renewable energy, then yes, they can be cleaner, but:

      2. we don’t have enough (mineable) rare earths to replace even a sizeable fraction of the world’s car market with electric vehicles

        The dirtiest, least efficient coal power plant is still IMMENSELY more efficient than a car combustion engine. When you don’t have to make your energy generating device mobile, you can get a LOT more power from your fuel.

        Maybe spend some time learning about a subject before you make claims about it. There’s less chance of looking like an ignorant fool that way.

          First things first: Yours is a straw-man argument. I said that electric cars are not “green energy” because it matters how the energy is produced. You, however, argue for the better efficieny vs. combustion engines. I did not even MENTION combustion engines. So watch your tone, dumbass :p /s

          Regarding your straw-man, I’ll bite:

          Efficiency of an electric car is up to 65% including losses when charging. Efficiency of a Diesel powered car is up to 45%. Producing a liter of diesel costs about 1.13 times as much energy as is contained in a liter of Diesel fuel, which - even assuming 100% efficiency on winning that energy - is further bringing down the efficiency to 45% * (1 / 2.13 ) = 21% (one unit gained per 2.13 units invested). A coal power plant is at best reaching 45% energy efficiency, bringing the overall efficiency of an electric car down to 65% * 45% = 29.3%. That makes an electric car operating on coal generated electricity about 29.3% / 21% = 1.395 or about 40% more efficient than a Diesel powered car.

          And this does NOT include that electrical vehicles are - due to the weight of batteries - around 50% heavier than combustion engine cars, and that battery life is much shorter and then generates a lot of electronic waste.

          Accordingly:

          The dirtiest, least efficient coal power plant is still IMMENSELY more efficient than a car combustion engine

          Not true. Numbers for the most efficient coal power plants are just about equal with the efficiency of the best Diesel engines. But even moderate Diesel engines stay around 40% efficiency, whereas coal plants can be in the 30%-40% range easily.

          When you don’t have to make your energy generating device mobile, you can get a LOT more power from your fuel.

          1. generally, larger generator = better efficiency, yes, however:
          2. see above: this does not necessarily hold true when the batteries increase the total weight of your car by 50%

          While - all things considered (I honestly did not expect the production of Diesel to be quite so energy-inefficient) - electric cars fare better if driven at constant speed (or with good energy recuperation mechanisms on braking) and not taking into account the battery life, energy investment into that and chemical waste produced on production / disposal, they are far from getting “a LOT more power” from an “IMMENSELY more efficient” power plant.

          Maybe spend some time learning about a subject before you make claims about it. There’s less chance of looking like an ignorant fool that way.

          Likewise.

          As I was saying in my first comment: If energy is produced by renewable sources, then they can be clean, so there’s no argument here.

          Re:

          https://www.sustainabilitybynumbers.com/p/lithium-electric-vehicles

          1. the article focuses on lithium, which is not the only problematic material used in electric batteries
          2. the first source I checked (on total lithium in the world) was offline, so I could not confirm my suspicion that the author was talking about the total amounts including those inaccessible in the Earth’s mantle
          3. the author admits herself that we have “enough lithium for decades to come”, which is in-fucking-credibly stupid, because this planet has been around for billions of years, and one of the biggest flaws of mankind has been to empty a natural resource over a few decades “coz profits”. Creating a demand for a resource that would only make it last a few decades would create another clusterfuck like all the wars and blood shed over crude oil. As a matter of fact, for mining conditions, we already have this clusterfuck, if you look at e.g. how cobalt is mined in the “democratic” republic of Congo

          Finally, like I asked another commenter: could you provide a source on EV batteries made without rare earths?

          By the way - sodium requires salt, and that’s also limited on Earth. Knowing mankind, we’d extract locally (desalinification hurts the ecosystem there) and dump waste locally in another location (again, hurting the ecosystem).

          My overall point is: the world’s car market is just too big and we need to shrink it, but mankind as a whole is too fucking selfish and stupid and short-sighted to accomplish that, and I WISH time will prove me wrong on that.

            People also dont get the differece between average and marginal. Adding consumption doesn’t build more wind farms. Adding extra electricity consumption means in short run burning more coal and gas. They are the ones that can be ramped up / ran more hours.

            In the long run they might build more nuclear, but that takes a (very) long time. Generally they’re building solar and wind pretty fast already, it is hard (costly) to ramp that up.

            Adding new sources of electricity consumption just keeps the fossil fuel power stations running for longer. Efficiiency is stuff like electric mass transit to replace as many car trips as possible - and using as much wires as possible instead of batteries. But no all the money will go into facilities and subsidy for battery powered cars.

              I think that’s only gas plants, that can react dynamically to changes in the grid?

              I think what we need is consumer electronics that can tolerate more variation in the grid power supply - e.g. a laundry machine that runs on 80% voltage just as well, but then takes a bit longer to finish.

              Nuclear power plants are only preferable to burning fossil fuels, and only when run by responsible entities (i.e. not by humans ;) - definitely not by profit-oriented corps) - I hope we can transition to enough wind, water & solar power, but we definitely need to cut down on energy consumption.

        Secondly, they’re becoming increasingly less reliant on rare earth metals and all that can be recycled anyway

        Their battery can be used for v2g to assist solar and further transition

        Finally, they’re incredibly effectively compared to combustion.

        In comparison to combustion and hybrid, they’re way cleaner over the entire life

        And now with sodium batteries coming into the market, they’ll increasingly become so.

        Are they as clean as bikes? No

        But not everyone wants to be isolated within 5km of public transport and their home.

        I’d have to travel 2 hours by train to get to work, and wouldn’t be able to go mountaineering or hiking anymore

        Also, what’s with the nonsense about there aren’t enough mineral resources.

        EVs don’t need to use lithium batteries. The technology can evolve with any battery chemistry or power source.

        Whereas gas or hydrogen is limited to those two options permanently

        Hydrogen in particular has absolutely s*** efficiency in all parts of the process. It’s only clean if you ignore the high energy wastage

          1. Solar panels need to run for a couple of years before they produce net energy considering the energy invested into production

          2. Source on battery production being less reliant on rare earths?

          3. Speak English, please - I am not looking up abbreviations to argue with you

          4. See my other reply here: https://lemmy.world/comment/12349903 Efficiency of an electrical car is better, but absolutely not “incredibly” better, as per the numbers I checked while writing that comment

          5. How much cleaner EVs are, depends on the source of energy mix (which at charging stations outside your home, you can hardly control) - if renewable energies are used, they are certainly cleaner. If fossil fuels are used, they are at best (not counting the waste from battery production and disposal) as much cleaner as the efficiency improvement (which is about 40% over Diesel engines, by what I calculated from sources that were acceptably credible for writing an internet comment as opposed to a scientific paper)

          6. I was not speaking about “mineral” resources, I was speaking about mineable rare earths. Because there are plenty in the Earth’s mantle, but we can’t get to those.

          7. Again, source please on how EVs do not need rare earths for batteries

          8. Agreed for the time being, but if research allows to improve the process for generation of hydrogen, it could be a cleaner combustion fuel

          In summary: I am not arguing for combustion cars, I am arguing against EVs not for individual use cases, but as a “this solves all problems with combustion engines” - because it is not a solution applicable to the world market for personal mobility.

          The best solution is a proper public transportation system - good bus connections and trains that can operate “by wire” without the need for batteries.

      I read in a firefighter’s thread that the trick is to use a low pressure spray directly on the battery compartment. (It was a thread about Tesla cars not semis though so that might not apply)

      The reason was you can’t actually put the fire out, it’s self oxidizing (it can literally burn underwater) so you basically need to wait till it burns itself out. Fortunately batteries only hold something like 1/10th the energy of gasoline and can’t release that energy as quickly so a fine light spray is enough to keep it from getting hot enough to catch anything else on fire including batteries in the surrounding battery modules.

      Takes a long time, like hours to get it to a point they can move the vehicle and literally a couple weeks before the reaction completely fizzles out. They have special lots they tow them to where the car can fizzle itself out without damaging anything surrounding it.

        But it would take a long time to open each packet and spray it on the fire.

        1. Lay the Capri Suns in the ground next to the fire
        2. Get another semi truck
        3. Drive over the packets to squish out the liquid onto the fire
        4. If the additional semi truck catches fire as well, repeat from step 1

      I don’t even think this is the right metric to use.

      You aren’t putting a lithium battery fire out with water. You’re just keeping it at bay until the energy is all used up. The more energy, the longer it’ll take.

      We might need new ways to deal with these fires, but it’s not like we can completely submerge a semi in water.

      I wonder how encasing the object in a fire retardant foam would behave, although we gotta think about the toxicity of that too.

      Edit: I wonder if you could even calculate the amount of water you’d need to hold it off upfront based off the battery size and current charge.

        There’s already tools to deal with lithium fires, class D fire extinguishers, sand and vermiculite. When I worked heavily with lithium non-rechargables we had lithium disaster plans for fires, explicitly in that was alerting fire fighters that it’s a combustible metal fire so they can react accordingly, those fires need to be smothered afaik, water was a big no no.

        Generally though, the plan was, escape and enforce a quarantine zone because primary cells give off nasty stuff, if you can drop it in a bucket of vermiculite if it’s out of the containment vessels and pretty much let them do their thing. Then once it seems like it’s done, wait more time to make sure it’s actually safe with 30 minute gas tests, then package them for safe transport.

          The problem though is how do you do that in the middle of nowhere on the highway like in this case? We need something big enough and portable enough. They clearly didn’t have that for this fire.

            Totally fair, awareness is a big thing too, fire crews are professionals so I do think they made the best choice with what they were given, every firefighter I’ve met will absolutely do an assessment before doing anything.

            Don’t know their situation, were they just told vehicle fire not lithium fire? Maybe more lithium specific crews/equipment in the future, maybe battery compartments that can help contain? (As I said, with lithium batteries I’ve worked with in the past, pressure vessels, if they went off it was at least contained to inside that, they’d vent gasses still but at least the threat of fire was minimised)

              My bet is they were just told it was a fire, i doubt the person to drive by and report it would have known it was an electric truck.

              The batteries definitely do have fire protections, to help delay the spread. Dousing it with 50k gals of water may have prevented the spread to another compartment for all we know. For something as big and higher risk like a semi though maybe there’s a way to eject compartments. Like if a fire starts in Module 1 of 4, modules 2 to 4 can eject themselves further away. Then were only dealing with a 250kwh fire instead of a 1mwh fire. It would add weight though.

              Edit: And then while the firefighters keep the flames at bay, something could get attached to the other compartments and be dragged further away.

      Yep, the Tesla Semi has been in limited production, and in use as a hauler. It’s got up to a 500 mile range on its massive battery bank (with real world loads clocking at least 375) and it way outperforms diesel in the performance category.

      Of course, you still have to charge it, so that bit has to be sorted out first before long haul is viable with these.

      The purpose of the water is to cool the wreck and the area around it while the metal fire burns itself out, because waiting it out is the safest option for the firefighters.

      For as much as people want their Musky circlejerks. This is really just a problem with the switch the EVs that people aren’t willing to accept.

      There is no way to really stop an EV battery fire.

      The batteries in these cars are made up of several cells, packed into a watertight, fire resistant box. When just one of those cells goes it’s over. It can create a chemical reaction that can ignite the cells without the need for oxygen, pure heat will set them off.

      The only real way of dealing with them is to let them burn themselves out, and even after that they aren’t safe and could reignite.

          Lithium fires are self-oxidizing, so that won’t work. Burying it helps keep it from spreading, though.

          Maybe for smaller things, a regular car maybe.

          But by the time a suitable digging machine arrives on scene and digs a big enough hole for a semi it’d probably be faster to flood it with water. Not to mention what might be underneath the ground, so they’d also have to spend time determining if there’s any gas lines or whatever before they dig so they don’t make a much bigger problem

      This is not a Tesla problem. This is electric vehicle problem.

      My local fire department once had to put out the same VW Buzz 3 times because it kept re-igniting. Nowdays they have containers filled with water that they completely submerge electric vehicles into that had caught fire.

        It’s a Tesla problem in that it is a bumrushing tech that hasn’t matured for what it’s being used for because profit motive.

        And no, if the tech isn’t mature to be both useful AND safe in the event of failure operating in the world, it belongs in the lab, not up for sale.

        We shouldn’t be mass producing any vehicles that become bombs/environmental disasters that standard fire and rescue can’t appropriately address with reasonable tools upon crashing, because they inevitably will.

        Its a market capitalism problem. Fire, ready, aim because rush the pos to sale. Musk is certainly a standard bearer as a prominent “get government and society’s wellbeing out of the way of my quarterly profit expectations” asshole sociopath capitalist.

          We don’t have time to perfect and mature the tech though. That was 40 years ago. Now it’s whatever fucking works that isn’t fossil fuels and burning of them. It’s a damn sight safer than an ICE which is actually carrying extremely combustible liquids in it too. It’s not perfect but it’s better and this kind of " we have to hold off" is effectively supporting the status quo which is fuckig everything up as it is.

            I hear you, and that’s a valid point, but I see that more as a function of our insatiable need for the primary driver of our destruction: growth/metastasis.

            Growth is precisely what is destroying us. We need to find homeostasis with this world. We need to slow down, stop expanding supply chains, and work on making what powers these 100% clean first and foremost. Because right now, most electrics are functionally dirty too, their pollution just happens higher up the chain.

            We won’t do that of course, because the reality is most people in the developed world need to accept that wasteful things like fast food, ridiculous amounts of meat, and plastic that serves no necessary purpose, everything from pop figures to disposable water bottles available to people with reusable vessels out of convenience, need to be made illegal yesterday if we want our species to have a decent future.

            But our creature comforts are more important to us, and we will punish any politicians that try to call for genuine sacrifice. 🔥🤷🔥

              Entirely valid and I agree that continual growth is right at the heart of most of our problems. I guess most of my frustration comes from the fact we’ve had at least 40 years of warning, 20 more years of proper, severe warning and promises for action and now that we’re seeing day in, day out that all the warnings were right, we’re still not moving with any real purpose. I genuinely thought that COVID would show us what we need to do and how we could do it but nope, slipped right back into business as usual.

      It’s any lithium battery, not just one evil villain. At least you’re not recharging your car inside the living space of your house, like your computer or phone or e-bike or e-scooter or vacuum cleaner

      Personally I think there’s a market for a fire proof container for charging batteries. I’ve been thinking about stacking cinder blocks in my basement for charging yardcare and tool batteries such that they couldn’t catch anything just in case

        Good point. I’m not sure. It may be that we’re (I’m) hearing more about Teslas catching fire because they’re the largest distributor in the US (and I live here). However, they’re not the largest in the world and I haven’t heard of this problem happening with other EVs (though they may be).

        Regardless, Elon Musk is a pompous charlatan and defrauder that deserves much worse than he’ll ever get. Bias be damned.

          You don’t hear about them because Western media doesn’t make as big a deal about them.

          If you can throw the word Tesla or Elon on something it gets plastered everywhere, including here.

          Same with recalls.

          Tesla recalls something software related like the unbuckled seat belt chime not working if you do steps A B then C and its huge news. Within the next 2 weeks 5 or 6 other major OEMs do recalls and you barely hear about it. And yes, recalls happen in groups like that where other OEMs wait for someone to go first and take the bigger hit.

            That’s fair. I fully acknowledge my limited scope/understanding and bias.

            I wish we lived in a better world with better intentioned people overall. It’s easy to focus on Elon Musk because he’s the biggest/loudest dragon, hoarding the most gold. There are others just like him everywhere. It’s depressing and overwhelming.

            I’m not a fan of cars in general, but understand their necessity in plenty of situations. EVs have great potential, but need good-intentioned engineers with plenty of oversight to safely fuel their development. I’m sure these companies have some brilliant scientific minds in there and they should be allowed to usher in a new age of invention, not limited by the bottom line of vampiric shareholders and the egos of CEOs. It’s just so sad.

              Not specific to cars but it’s sad to think about what we could have had if we let these people build things properly. So many things don’t happen due to money. Inventions and knowledge getting bought and squashed as it’d interfere with the bigger companies plans etc.
