After working on natural gas trucks for the last few years diesel isn't going anywhere anytime soon
What about natural gas trucks? There is even synthetic natural gas.
Natural gas trucks suck bad in the winter. They are gutless turds and don’t run half the season anyway. At least in the Mack platform. Mack BEV is garbage and takes dozens of gallons of diesel via gen set to keep charged. Batteries fail while sitting and need replaced. The subset of batteries for the cab alone weighs 1200 lbs. junk. Anyone remember DME? Dimethylether. Yeah they squashed that. Liquid fuel derived from methane that is compression ignition and requires only scr for after treatment. Would have been able to run no egr, no dpf, no vgt, no common rail. Could have been mechanical injection and old school turbo. As a technician I’m for anything that works well. Nothing but diesel works well. Hydrogen is hard to make in large quantities and store on the vehicle but not much worse than natural gas I suppose.
Over time in select areas it may be phased mostly out, but I agree diesel is just too established and effective to disappear anytime soon
Pounds moved per gallon burned a big rig diesel is one of the most efficient machines out there.
@@deltafreshrelics1660Propane or natural gas assist would have been better.
Building an engine that can burn hydrogen is the easy part. Making green hydrogen and developing an effective way to carry it in the vehicle is the challenge.
Agreed.
Burning hydrogen, should be the epitome of Clean emissions.
@@user-on3zq2nc7l It should be, the problem is how to produce it, whether through electrolysis, how the elecricity for electrolysis is generated, or whether the hydrogen is extracted from a fossil fuel source such as natural gas.
The best place to produce Hydrogen at $0.25 per gasoline gallon equivalent ($0.25KG) is in abandoned or existing oil and gas wells. The production of "clear" hydrogen leaves all the air pollution underground unlike steam reformation of natural gas or gasification of coal releases Co2 into the atmosphere. The company called Proton Technology, Inc in Canada is worth investigating to produce "clear" hydrogen wil be the easy part competing with natural gas and subsidized hydrogen.
They already have the technology you’re talking about most of your forklifts in the industry are running on hydrogen nowadays. There are a lot of smaller engines, three cylinders and what not that run on hydrogen also in the commercial industry, it’s a mith that electric vehicles are safer and easier to produce.
Remember that no matter what you use to power an engine you will still need to lubricate all the moving parts in the engine and all other parts of the drive system. So in other words we will still need crude oil for lubrication.
And tires, and synthetic rubber seals, and energy for manufacturing.
And crude is rich in hydrogen
As a 47 year old diesel tech, I’m glad I’ll be retired when diesels are totally phased out . And I’ll finally say goodbye to an old friend that caused me many headaches and pains throughout the years, but earned me a pretty decent income to where I was able to enjoy the good life.
That statement have a point ?
@@SatansChoice nope. Does yours?
Good deal - you timed it just right! My first job out of school was working for Cummins. I worked on the small engines that are used in Dodge trucks. (It was a joint venture with Case btw. Half the engine production went to Cummins to sell and half went to Case to put in their equipment.)
Hydrogen embrittlement is the issue.
Electricity is the future
Don''t worry, diesels won't be retired anytime soon. 99% of these so called "green technologies" are nothing but a scam funded by taxpayers through government subsidies. Once subsidies dries out, the scam is over and everyone returns to using good old diesel, simply because no one has figured anything better so far.
This was a headline back in the early 90s. Fewer things are more sustainable than a diesel engine if government regulations didn’t interfere as they encourage ethanol fuels that create more low level ozone emissions and push environmentally unfriendly “Green” energy. It’s never been about being environmentally friendly but about power.
The huge problem is that there is virtually no nationwide fuel network. Would cost billions and a heck of a larger carbon footprint to make it a reality. So you can still have emissions anyway.....
No such thing as zero emissions ever, in anything.
Nope, but long as the propagander is smarter and better represented than the propagandee, then the ability to control the masses remains.
Toyota and Cummins are paving the road and the right path with this technology, it’s only a matter of creating the infrastructure to make it feasible. Electric is not the answer but hydrogen 👍
"only a matter of creating the infrastructure to make it feasible" Anyone got a magic wand?
@@nickwinn7812- “magic wand”
H2 @ Loves Travel Stop… all problems solved
And j.c.b. in England rolling out hydrogen excavators as we speak.. they have a hydrogen feeder vehicle that can supply 16 machines to run all day 12 hours .500bar feeder tank fills 350bar excavator tank. Simple pressure drop transfer. People could adopt this system and have a home storage tank which can also run a heating boiler. As is currently done with oil or l.p.g. on site storage.
“magic wand” - Amazon & Walmart warehouses use H2 for their forklifts, instead of toxic batteries 🪫 … infrastructure exists, across North America, it just needs to break out of the warehouses.
Perhaps, they can become the next filling stations! LOL! 😂
Why hasn't the infrasructure broken out of the wharehouses? (infrastructure cannot exist in wharehouses by definition - but we'll skip over that). Amazon and Walmart's H2 comes from toxic fossil fuels !!!!!! Not all batteries are toxic and none pollute during normal operation. Almost all can be re-cycled. You can choose whether to pollute the planet by mining a fossil fuel which you burn one time only, or you pollute the planet by mining the materials for a battery which can be used thousands of times and then re-cycled..Get it?@@DavidHalko
Here's some background you may find helpful - when thinking of climate and energy - especially wrt CO2. In the Precambrian era there was about 5,000 parts per million of CO2 in the atmosphere. At that time, the earth was lush, green and healthy. However, as shellfish in the oceans began to flourish, these creatures began to strip CO2 out of the air and capture it in the shells of the dead shellfish (i.e. the white cliffs of dover and limestone in the earth's crust are a good examples of gigatons of CO2 that's been sequestered). Over a half a billion years the plants in the oceans pulled lowered the CO2 in the air from 5,000 ppm to 180 ppm! And 180 ppm is only 50 ppm above where the plants begin to die! So, because of man adding CO2 to the air we have essentially saved the planet from extinction. This was by accident, of course, as was the plants taking CO2 out of the air and storing it in the earth. But each process has had critical implications to our planet. So, if these evil, greedy eco-idiots are successful - which thank god they won't be - they will destroy the planet, as we know it. And we can all see the benefit of man's added CO2. The planet has gotten greener, as man added CO2 to the air! We have seen this from satellite data. It is real - we have proof. Unlike the lying climate models - the real data shows the facts. BTW did you know that greenhouse growers add CO2 to their facilities? Yes they do - because it increases plant health, growth and crop yields. Just like crop yields have gone up all across earth due to the extra PLANT FOOD called CO2. Don't believe me - go watch this video to see for your self - "Meet Dr Patrick Moore: Greenpeace co-founder who left the organisation hijacked by political left". Cheers.
To me it is really simple CO2 cannot be a polutant becuase reducing it to zero, like these morons are proposing, would eliminate all life on Earth. If you allow the enemies of humanity to convince you that CO2 is a polutant you will never win any argument with them about their climate alarmism hustle.
10,000 years ago 3/4 of North America was covered in 2 mile thick sheets of ice. Greta thinks caveman campfires to stay warm, released CO2 and caused all the glaciers to melt.
Wish ćĺìmâțè change àćțívìśţś would actually research that the planet has been getting better for a long time thanks to natural human innovation and not authoritarian government rules that make no sense.
What was the temperature back then @ 5000 ppm ?
small detail left out, it's just that the pesky earth temperature keeps going up dramatically since the introduction of man's use of fossil fuels, among a few other reasons, resulting in rising oceans, more unpredictable, violent weather. Did you miss that part?
So does this solve the problems of hydrogen energy density, collection, storage and transport? Burning hydrogen in an engine to generate torque is not particularly difficult. It is all the HUGE technical issues with providing an infrastructure that would allow us to store, distribute and use it efficiently. that have always been the limiting factor of our ability to use it…
Hey the govt has war to monger $$$ to launder so shut up about the infrastructure thingy eh
There is no free hydrogen, most is in the form of H2O, so these engines are indirect coal and natural gas powered from the electrolysis of water by electricity. Huge 10,000 psi compressed hydrogen tanks vs relatively safe diesel fuel. Just transferring more load to the electric power grid.... just like coal powered electric vehicles.
10,000psi tanks, even if it doesn't explode, the release of that much pressure will be an explosion in itself.
10,000 psi!
A wreck is an obvious cause.
Road debris that gets airborne, all it takes is a board on the freeway to become airborne, doesn't even have to hit the tank but knock off the fittings from the tank.
I could see it in trains, not roads.
I hope Cummins succeeds at this endeavor. Toyota already has the Mirai which ones on hydrogen, so the technology is there and Cummins can succeed. Whether we like or not the combustion engine is dead and new technology like EVs and hydrogen is the new technology. Also I think more mass transportation and high speed trains running on clean energy is necessary.
The 12.7 Detroit 60 series is the best truck engine ever made
And that is your opinion but wtf does that have to do with hydrogen and this forum?
We're all screwed if they think this will ever be 'zero' emissions. There is no such thing as zero emissions.
If a hydroelectric plant makes electricity to power an electric vehicle that is one example of what is termed "zero emissions".
@28704joe exactly my point, zero emissions is a bullshit term. Emissions would be created in building such infrastructure, and it doesn't scale. Pie in the sky.
@@28704joe NO! Manufacturing an EV is extremely dirty and is in no way zero emissions; besides, Hydo-power only accounts for a few percent of electricity produced. Wind and Solar are also very dirty to make and are expensive to maintain; and that is to say nothing about their capricious availability!!
You can extract hydrogen directly with solar panels and a tank of water and there is no emission but water vapor but when everything is converted to grid power in batteries they turn off the switch and unless you're a billionaire you're dead that's the point
We should have been moving this way since the 70s not in ten years
Hydrogen has been tried and failed several times before, and Diesel just works, it is simple, easy, reliable, robust, cheap, etc
Exactly
Well, it's not cheap at the pump.
@@davidsmith385 It should be because it's far cheaper to produce. But in my area it's not that much more expensive than petrol at the moment.
@@davidsmith385 the diesel is cheap , the taxes, levies, fees, eco, carbon,etc is what cost.
the problem is the petro pollution, emissions
I am encouraged by the engine configuration options Cummins is producing. Biodiesel is still a reasonable option.
If the engine is specifically built for it. I owned a fleet in the 90s and got a gonga deal for biodiesel. The trucks didn't perform anywhere near their performance on diesel and the 5 - 8 mpg loss wasn't worth running it. It cost just as much as if I had been running diesel at the end of the month.
Everyone just needs to follow the steps of Edison motors up in Alberta, do a smaller diesel powered generator under the hood, which will top off a battery bank. The truck itself is fully electric though. Absolutely love the applications that setup will bring.
The 6.7 is also a bus engine used in hybrid buses
I hope they make a retrofit kit for existing Dodge and existing Ram trucks a crate system
FYI, diesel can run on any type of oil. So it doesn't really matter.
@@blackonblack...9244that may be true but on the newer cars the computer might not like that different mixture. I have a hydrogen generator but I'm not going to hook it up to my 92 Cummins. A lawn mower perhaps but not a 7000$ diesel engine.
@@ronskancke1489 I never said you should. I'm just saying it can.
Hope it works better than the cng failure
Hydrogen has been tried before in trucks and it didn't work, hope improvements work
Years ago a guy in Utah invented this type of engine. This is old, but interesting new.
yet another problem with Hydrogen is energy density, how much power/work can you get in a 20 gal tank
What do you think of Revolving Intake/Exhaust Camshaft Valves, or Integrated Overhead Camshaft?
They need to do this to ships and trains which would do more than putting in trucks and cars
I know that in Australia they're meant to be building a hydrogen gas fuelled power station but the prime mover can only use 15% hydrogen gas & the rest has to be natural gas which is extracted from the ground.
Whoever designed the power station says that they can possibly bump that up to 30% hydrogen gas usage !
I think this is a much better option then huge battery banks that take hours to charge. The key part I took away is the existing manufacturing platforms don't need excessive overhaul to make this a reality. For me loving old school hot rods we can just make them run on hydrogen so we can still have fun with cars and trucks.
I believe Cummins if anyone can make an efficient hydrogen engine & I believe investment in Hydrogen or Biodiesel is far better than Battery given the huge carbon foot print mining for all of the rare metals to create batteries & the pollution from disposal of them but we have been working on an efficient way to create hydrogen fuels for over 20 years now . Nothing is Zero emissions but t least we can move toward renewable sources .
How reliable will these overhead cam hydrogen engines be? The simplicity of good old push rod diesels can't be beaten.
Only if the engineers have designed every part to NOT fail for hundreds of thousands of miles. Seems like they designed some engine parts on GM and the rest to fail. Small very expensive parts that fail to save a damn dollar. It’s ridiculous to do use plastic etc inside an engine. Like timing chain tensioners and gears etc. How damn stupid
"California has already banned ... [itself]."
This is basically an ad for Cummins' greenwash.
ICE is only half the solution, storage/transport is the other more pernicious problem.
There was a hydrogen engine on display in a faculty foyer of the Tasmanian University in 1979 ! The only way it will ever be practical is if we can fill up on water, and have a splitting solution live in the semi.
I can see California in 20 years where everything is delivered in a rickshaw.
How much energy does it take to make a gallon of hydrogen?
It doesn't matter if it takes slightly more energy to extract hydrogen you cannot put all of your eggs in one basket the grid and batteries what if the grid goes down everyone dies
@@zedostenso3069 The Proton Technology Inc in Canada claims $0.25 per gasoline gallon equivalent for Hydrogen gasesous fuel by recycling abandoned oil wells.
'JCB is moving to hydrogen power for all their big machinery. Here’s why.' is an interesting watch also
Yes I saw that big lean burn clean motors I think with rather large turbos??
I think this optimistic outlook needs a dose of reality... The elephant in the room issue of where is the Hydrogen going to come from needs to be more developed! To my understanding California and Hawaii are the only states to have a supply and distribution network. The current cost of a plant to provide Hydrogen gas is a mere $Billion per each plus a distribution fleet and filling station infrastructure for 48 other States. A serious pricey nut to swallow requiring time and serious funding.
Would be good to see these engines using the Coates rotary valve heads
I see a big problem with hydrogen production at affordable prices.
See Proton Technology, Inc in Canada that can produce hydrogen twenty five cents gasoline gallon equivalent or $0.25 kilo gram while Hydrogen per KG in Los Angeles sells for $14 Kilo Gram KG.
As long as it is a fuel on demand system then it's a great idea , carry your own water as fuel .
This isn't mentioned enough. On board hydrogen production. They claim you lose as much from the extra drain on the alternator but I have my doubts. Not enough powerful people and corporations can get rich off that system so there is where the opposition comes from.
Natural Gas is a smart, low-emission alternative to gasoline and diesel- and it delivers similar horsepower ratings. Premium gasoline is 91 octane, while natural gas has an octane rating of approximately 130.
Yes, low co2 emissions but not for methane. Methane is an 80x more powerful greenhouse gas. Leaks happen all the time in the energy industry.
@@anthonylanglois8267 way less pollution than diesel of course .This truck has a less complex after treatment system , can also run on Zero emission CNG .
Yes ..True
Octane isn't a measure of quality, it's just the point of combustibility. 130 just means it is not very adaptable for regular engines.
@@Scott-fy7fm All fuels need to be blended.
It is 12 min advertisement without much information on how hydrogen works in existing internal combustion engine. Cruel.
The mental simplicity of journalists can be mind boggling
Briliant we all should go this way no batteries 🎉🎉🎉
How big will the explosion be when one of the vehicles are involved in a wreck?
Scientist have discovered how their will be no explosions of hydrogen when it's safely stored in water mixed with banking soda. Can you imagine a fuel source that's so safe it can be used to extinguish a fire.
@@leroyessel2010 I hope you are right. I think the EV. Vehicle is not a good idea.
I see a picture of the Hindenburg blimp ina wreck 😮
What that means is you get the same fire as when a ev crashes. You just get it a lot faster.
So a ev doesn't go bang in a accident it just burns up . Yippee kiyaye.
I think the problem with this "Hydrogen Revolution" is the Hydrogen itself.. Yes it's "efficient" in it's energy and processes after the manufacture of this fuel, but not before. Hydrogen consumes almost twice the energy for manufacture than it provides for work, not good for an "efficient" fuel.
Remember when Propane became a popular alternate fuel in the "Energy Crisis" of the 80's, it was extremely cheap with only a small degradation in power and efficiency.. but that didn't last long before "road taxes" etc were added to the fuel as a surcharge and priced it right out of the market. It didn't cost any more to manufacture, greed just came into the picture and the fuel market equalized once again. There is no way you are going to get further on a dollar by using any particular fuel, that's just the way government is going to keep it.
Asia has allowed hydrogen fueled vehicles for a while now, just long enough to get some startling statistics regarding safety and refueling.. personally, I don't think the north American markets are ready for the pressurized systems needed to contain and dispense this fuel. Once people begin to understand the difference between a disposable/recyclable battery and a tank of fuel that evaporates and why either works better in it's own environment, we will continue to force ridiculous tech despite it's feasibility.
Ahhh, batteries are NOT disposable, they require Lithium, go look at what is being done to vast tracts of land for the mining of this. Electricity requires generation, this requires copper, which the mining of toxicic. Vast tracts of grasslands killed off by non reusable non disposable panels, vastly more transformers filled with PCB's for insulation and cooling, (the most toxic substance known to man except for maroonic climate conspiritorialists). The obvious solution to the CO2 issue is to plant billions more trees!
Yep. And propane started as a by product of natural gas. Hell, they were giving it away to anyone who could show up with a tanker to haul it in the beginning.
Awful convenient or would that be inconvenient when there's no other sources of energy except grid power and battery and then oh my God the great went out I'm sorry you're dead
Nobody said it was "efficient", just that it works well as a fuel source and has zero emissions from the vehicle. It's 20 times better than electric vehicles.
There's no free lunch.
Stellantis purchase a huge massive share from Symbio and they did introduced a hydrogen power ram truck before this means they are interested in bringing back the Hemi in Hydrogen form because of 0 emissions and on top of that most of their audience are not thrilled of killing off the combustion gas hemi engines
You can produce hydrogen with a battery, electrodes and water.
This is amazing stuff.
Great vid.
How they address hydrogen embrittlenes of steel?in engine combustion parts and to the hydrogen storage tank?pls reply.
Town gas has been used for electrical generation for years. Local large hospital has two units. So using hydrogen is no big deal. However storage and transference of hydrogen is still tricky. What is the Cummins solution to this? Noticed that part of the set up is mentioned, but has needing further work.
Yup, hydrogen cannot be contained in steel bottles. The molecules are so small, that they leak through the micro structure of the steel. And this causes the steel to go brittle. And what about engine itself and fuel piping? This would have the same problem. I've never heard what the solution is. Slick sales videos are aimed at the general public who know nothing about such details.
So... what are the tires made of?
In the illustrations, they showed upright tanks up against the back of the cab. This is a disaster waiting to happen in real world applications of OTR simi trucks.
Accidents do happen. Freight shifts. Even in box trailers, the freight can come THROUGH the front of the trailer, crushing those upright tanks. BOOM!!! With that volume of hydrogen, everything in a square mile could be obliterated.
If the tanks are made to withstand all but the worst crushing, (and they should be) they would be so heavy, the semi truck's viable usability would be greatly reduced. No one will buy a semi tractor that is too heavy to legally pull enough freight to make a profit.
The water engine that converts to hydrogen on board is the way to go. It would be life changing and it would be much safer .
Truck drivers like to drive 8-10 hours non-stop. How big is that Hydrogen tank going to be?
These people have lots of alternative technologies... they just release them at the right time so that their profits are not affected.
They talked about using hydrogen in the 60s one of the problems was making and have hydrogen economically the other problem is you would need twice as much liquid hydrogen as it to diesel.
Yes, size of tanks required to carry enough hydrogen.
Safety requirements to refill.
Canada is also working on this, half of Europe also, gotta have enough fuel to run turbines to charge batteries, 1 turbine uses 100 gallons of fuel a minute, made in China by GE, hydrogen cooled generators on the end, nuclear for electricity, hydrogen for cars
Everytime I hear hydrogen engine,my brain 🧠 sees the Hindenburg
Believe it when I see it...
!
Also have Amonia engine technology ,especially for BIG engines .
It's time for me to pull my antennas up and find out all I can find out about hydrogen
Watch these guys figure out how to convert the un inhibited no def no egr hydrogen engines back to diesel… these engines will be highly sought after for their convertibility…
Temperatures and pressures in a hydrogen ICE will produce Nitrogen oxides. A hydrogen ICE with no emission controls is a Marxist pipe dream.
As Peter Zeihan stated just last month, even by the most aggressive progress there will never be enough green energy produced this century (not including the use of nuclear power) to produce hydrogen from water at commercial scale.
The biggest obstacle for hydrogen is it's very small molecule and the temp it turns into a liquid. The small molecule means leaks. The temp problem means it has to be cooled way down to -427F to make it a liquid. Natural gas is much easier to work with than hydrogen. These problems were addressed by SpaceX when they were designing their newest rocket engine. They went with Methane. Natural gas is about 70-90% methane.
What type of metal are they using in the pistons? I know in the past the aluminum ones did not hold up to the high temperatures of hydrogen long term
One can only wonder how much coal will be burned to power the electrolytic generation of enough hydrogen gas to power all those trucks. Adequate purification of enough water for this process is another inconvenient detail. People having fewer kids is the only real answer and few want to talk about it.
This is where the nuclear reactor enters on picture.
. Have fewer kids? Thats the most ridiculous thing I have ever heard of. Where on earth did you come up with that idea ? Archie Bunkers?
CUMMINS DID IT AGAIN ✨✨✨🙌❤️💯💯💯
Of course, it's vastly more efficient (miles per cubic whatever of hydrogen) to use an HFC with electric propulsion, than to burn the stuff. When using it as ICE fuel, once you get past the embrittlement issue, it's just an ICE.
Water doesn't mix with water, so any vapor that leaks past piston rings into sump oil will reduce the life of Bearings. So it would have to be a pure burn rate.
It’s not a the doom, it’s a evolution. Let it make light of hydro electric power.
Hydrogen is cleaner by far, but where will we get the hydrogen fuel and how much will it cost
Break even is an electricity price of 3 cents per kWh.
That currently happens with solar power for about four hours per day in summer (actually currently the electricity price goes negative (the grid pays large consumers to take more power).
Direct connections between solar farms, hydrogen electrolytic plants and the gas grid could help solve this distribution problem.
700Bar is scary! That's 700 x 14.2p.s.i. ? If a truck fire? A bad highway crash! A terrorist attack at a haul ! That would make Pearl Harbour seem a small firework display!
What I have yet to figure out.... is why are they ( EPA IM SURE) so adamant about doing away with diesel when it burns cleaner and hotter than gas???
I have listened to the critics for over 40 years, they say "NO WAY". Now use your eyes, and you will see that Hydrogen is becoming a slow reality. You can use that wonderful Lithium to try and get there, but you know who controls the Lithium (China). Have you ever tried to put out a Lithium fire? I hope you don't use water, that will just piss it off more. How about what do you do will all those batteries that need to be thrown away,? I had a person tell me that you need the Lithium Batteries for Fuel Cell cars as well, he did not realize that the Hydrogen is the battery. How about what it does to the earth to extract Lithium. They are figuring out how to store Hydrogen in solid form, it will be a game changer. I'll keep listening to everyone tell me how it wont happen, as I see it starting to take shape. Thank you Cummins.
A great deal of the world's lithium is in South America. Australia is a big producer too. Besides, the same type of metal-oxide battery can be made of sodium, which is abundant everywhere.
We have Deuterium deposit in Pacific Ocean. Deuterium is called a Hydrogen liquid or heavy water by nature because in Philippine deep hydrogen seperate thru water by nature if pressure of 10k psi in deep trench.
No worst than propane powered vehicles!
It wont be worst propane fords were horrible
So where will all these trucks be filled at?
And back in the real world.
Burning hydrogen in an internal combusrion engine is NOT pollution free. It creates a lot of nasty NOx gasses. You still need to add urea to the exhaust. Nitrogen comes largely from Methane gas at the moment.
EPA behind 50+ years. It's not new hydrogen power technology, I thought of that in the 70's.
The main problem for all alternative fuels is infrastructure. Unless the government gets behind a fuel and builds the infrastructure to support it, it doesn't matter how great the technology is. Right now, the only alternative is electricity, simply because it is already built and being upgraded for future needs.
ITS ABOUT TIME , ONLY ABOUT 100 YRS TO LATE , PERIOD !!!!!
The design itself remains an Internal Combustion engine aka heat engine. At the very best, the energy conversion to mechanical energy is about 40%. The losses are wasted heat and internal friction by design. With hydrogen it is carbon free of course and the emissions are not harmful. Hydrogen itself has to be "made" with the input of more energy than is returned in the form of hydrogen. Currently most hydrogen in use is made from natural gas with left-over chemicals, drilling, pipelines etc. Hydrogen's heat content by volume is very low in BTU output. Hydrogen also has storage issues by either highly compressed gas or cryo storage with layered tanks and venting losses. Since hydrogen functions as an energy storage device, it makes more sense to use a battery to do that. Modern electric motors operate in the 80% energy conversion range. Most of the electrical infrastructure is already in place. The issue with electrics is recharging time down which may have improvements coming and perhaps swap arrangements which have been in use for years in industrial vehicles. Cummins is of course heavy in the trucking field and industrial engines and this hydrogen design may well have special use application as in cross-country trucking or dense metro delivery use where vehicle emissions are a major problem.
A diesel engine is compression ignition. An otto engine is compression spark ignition. This diesel engine isn't a diesel engine, not because it burns hydrogen, but because it needs spark plugs to ignite the fuel-air mixture.
At the end you say BEV will continue to use fossil fuel energy whereas green hydrogen is CO2 free. First of all, there is no reason for BEVs to use electricity from fossil fuels. Secondly, if electricity is made from fossil fuels, then making hydrogen with that electricity will be no better (it will be worse). At the moment something like 0,5% of all hydrogen production is green, most of the production is from natural gas hence not green.
BEV is a far more efficient use of electricity than Hydrogen. There is no such thing as "green hydrogen"
So using MORE electrolytic hydrogen is a problem because?
Current photovoltaic arrays run at below half design capacity because the electric grid can’t handle the peak supply capacity. Tapping the surplus photovoltaic power at the source and dumping the hydrogen into the gas grid will help mitigate this supply / demand mismatch.
Currently 30% of the natural gas extracted globally is reformed to make hydrogen to make ammonia and hence nitrates. That has the potential for significant benefits.
@@allangibson8494 I'm not against using hydrogen when it's the better option, I'm not convinced that it is in this case. And as long as we (humanity) burn gigatons of coal and oil and gas, we can't really choose the most inefficient "solutions" to transition, we don't have excess energy.
@@aesma2522 We do currently have excess energy in most of the western world, solar particularly in summer. That is the driver for negative electricity prices.
Long term storage is a significant problem for electricity generation. Current storage solutions are designed around days of storage - not month’s required to shift generation from summer to winter.
The alternative is to shift energy from the southern to northern hemisphere.
Hydrogen is one way to do this. That’s why the “Suiso Frontier” exists.
Shipping liquid hydrogen is not significantly harder than shipping liquid natural gas (with the other alternative being shipping liquid ammonia).
Western Australia is looking at using its existing liquid natural gas infrastructure for liquid hydrogen exports to Japan and India with photovoltaic arrays inland of Karratha and south of Darwin feeding power west and north.
Germany and Japan pushing into hydrogen iron reduction to complement their electric arc furnaces used for recycling steel which will significantly bump up demand.
@@allangibson8494 The problem is that hydrolizers aren't cheap, so investing in a plant then using it intermittently isn't ideal, a bit like nuclear power plants.
We aren’t even close to no pollution hydrogen is a good start a lot better than lithium powered electric vehicles but there are still hurdles to consider. It takes power to produce hydrogen. I love the idea I’ll love it more when the hydrogen producer is built into the car and yes, you will still need an electric start
Why didn't they use in line engines.More torque.Look what a problem the 5.0 for Nissan did.Problems galore.But I do hope they work.If they use "Gaseous" hydrogen...not liquid.
I can see it now. Those foreign truck videos where the truck is overloaded with loose pipes suddenly stopping, driving the pipes through the hydrogen tanks and cab. Kaboom! No need to look for the driver.
Exciting stuff. Because I think it's possible
6:58 uh… 35 milliWatt!😂 you probably ment to say 35 MegaWatt!
I would like to get one of those engines to drop in my 1947 Dodge tow truck, to make a really build over what they are bragging about the new 2024 Duramax diesel engine.
You know that's going to put the oil companies out of business
Just googled the price hydrogen per gallon it said it was roughly around $17 dollars a gallon. That’s a you can keep that shit for me no sale.
It will be a long time before hydrogen will replace diesel. Although hydrogen is the most abundant element in the universe, on the earth it is always bound to another element such as oxygen. The energy required to separate H2 from whatever it is bound is greater than what it can give back as a fuel. The cost of 'separating' H2 is also a significant factor. Although engines can certainly be designed to use H2 fuel, getting the fuel at a reasonable cost is the limiting factor. Another factor which is somewhat of a drawback has to do with how hydrogen is stored on a vehicle. Using a gas such as natural gas or hydrogen requires at this stage of the game high pressure vessels which are costly, heavy and require a larger volume for a given range than that needed for a liquid fuel such as diesel.
How far can you drive in any direction and refill your hydrogen tank ?.😅
Just like useless EVs
6:54 35 milliwatt ? WOW!!! you could power a car for an ant with that!!!
I just wanna know if “rolling coal” works like a water gun in one of these
At 6:50, it is 35MegaWatts, not 35 milliwatts.
The biggest problem as with electric vehicles is the infrastructure for the trucks. I would not bet on this technology or electrical powered engines. It would cost hundreds of billions of dollars to have hydrogen stations with the massive the available of diesel fuel. The wait time would be at least 2 to 4 times to refuel the hydrogen fuel tanks. Of course this could be attainable during the required rest periods required.
Time will tell 😊
Rip stanley allen meyer 1st h20 engine built 10 years ago 🤔
Super!
Funny thing is hydrogen fuel is perfectly clean to burn , but takes more energy to create than it produces ! Seems like a losing prospect , to burn more than you create ?
This way politicians can get more taxes and feel better while burning the cash.
As long as it takes 1 unit of energy to make 0.7 units of hydrogen energy hydrogen will be a stranded asset.
Storage and transportation of it still not viable in terms of energy and safety.
IF we make hydrogen from wholly renewable energy then it has a chance.
Otherwise it is a non starter.
Mike Copeland has already built a couple hydrogen powered vehicles that put out 500+hp with zero emissions. #ProjectZero
where the hydro station on interstate 10,20,40?????
