Toyota has developed a hydrogen combustion engine with nearly negligible harmful emissions. The project involved a Toyota Corolla Sport which participated in a 24 hour endurance race, using a 1.6L turbo inline three-cylinder out of the GR Yaris. The idea was to convert a gasoline engine to a hydrogen engine, as an alternative to creating new electric cars. With hydrogen combustion, oxygen and hydrogen are burned, providing useful work, with water as the only main emissions.
Naoaki Ito, one of the lead engineers on the project, puts it well: “For this hydrogen-powered engine, the engine itself remains the same as before. Our concept for this project was to create a hydrogen engine by using as much of the existing internal combustion technology as possible. We thought that achieving this would enable the conversion of existing car engines to hydrogen, providing a powerful weapon in the quest for carbon neutrality.”

I think the tank weight is still lighter than battery weight. Be interesting to see the weight difference and possible environment impacts.
With a 500Wh per 1 kg battery (CATL) coming out, a 100 kWh battery would weigh 200kg. BEV batteries are developing very fast. There's no real hope for hydrogen to win in small vehicles. Ships, trains, and maybe trucks, could have some use. But that 500Wh is the level where the game is also over for long-range trucks. A Freightliner consumes about 150 kW per 100km. That would be 300 kg. A 3 000 kg battery would give a 1 000 km range for that truck. 3 000 kg is not that much extra weight when you consider all the other tech you don't need anymore like a huge combustion engine, fuel tank, emissions systems, etc.

@Terry Winter Who (i.e. what's the source) says that electrical vehicles are more expensive and pollute more than conventional internal combustion vehicles ? Especially when evaluated over vehicle lifetime ?
Would very much like to "read up" on that but have not seen any reliable and credible material... No lack of opinions and speculations though!
Best regards
@Terry Winter
Which type of batteries are worse than what, and under which presumed circumstances ?
General "declarations" whitout more precise specifications are unfortunately of no use when one wants to investigate and understand factual problems and their circumstances...
Short (and often blusterous) simplifications might appear to be great soundbites and might even be in accordance with current findings. But they might just as well be mere slogans minted by some "interested party", and due to their brief and nebulous nature there is no proper way to determine which is the case, which renders them totally useless to anyone who is looking to actually inform them selves on an issue.

@@mpadlite2925 it looks like you are blindfolding yourself. The most common batteries used in EVs are totally reliant on RARE minerals. 80% suppled by China.

@@captainnavi6546 - Spoken like a person that has never driven a performance electric. If you like big V8s then you're almost certainly attracted to it because of its huge torque numbers and the fact that it can generate that torque low in the RPM band. Well, if you love loads of torque that comes on quick then you need to experience something with typically twice the torque of the average V8. You owe it to yourself to test drive a Tesla Model "S" or a Porsche Taycan (just to be able to objectively critique them if for no other reason). The instant levels of MASSIVE torque created at virtually zero RPM is absolutely intoxicating. You won't be able to keep your foot out of it.

This is an amazing presentation! I was much more hopeful for hydrogen . . .
Anyway, thank you for this insightful and thorough video!
Very interesting. But I think Toyota needs a lot of respect for trying all these different options, they seem to really care about ICE fans. I appreciate that.
Battery production capacity is the problem. Huge amount of investments needed and a big cut over their profits because of the battery cost in each car. Hydrogen combustion engines would maintain a bigger piece of the pie.
Money is always what they care about.
@@MuitoDaora It's not what "they" care about.
Hydrogen ICE simply makes more sense and is way better for the environment if you take into account the whole process chain of regular EVs.
Plus the ICE has been developed and optimized for decades now, it would be a total waste to throw it all away and start fresh.
Reinventing the wheel never works.
@@MuitoDaora if you're correct, why don't they simply take the money they're investing in hydrogen power and channel it into battery production so they get all the pie?
@@vinigretzky97 I'm not defending EVs, just saying that money in their pocket is what matters.
EVs are being pushed by regulators for their efficiency and possibility of not polluting the atmosphere by using renewable energy for the whole process but the mining problem persist.

Does this mean that hydrogen combustion spinning doritos are remotely theoretically possible now? 🤔
Mazda actually made a hydrogen powered RX8 available to Japan at one point
@@rzyao64 crap you're right, I thought for some reason that his video 2 years ago concluded that hydrogen rotaries weren't really possible. Thanks for correcting me
Wouldn't you need multiple Doritos per rotor? Jason mentioned some pretty high compression ratios, the easiest I've heard is using a big rotor for initial compression and final expansion and a smaller one for final compression and initial expansion.
Jason also made a video on why it isn't happening (Doritos in general, not multiple tricks or h2).
You can put the spinning Dorito on LPG... That will pass emissions
Liquid Piston engine. New rotary that can and does run on hydrogen. The channel Warped Perception just did a video on it.
My son is an engineer and was involved in the development of the Toyota Mirai fuel cell. He is currently working on next generation solid-state battery technology for EVs. I'm really proud of him.

I wish your son the best of luck in his research because I am absolutely Impatient to see Solid State Batteries become Mainstream
Except all methods of producing solid state batteries takes huge amounts of power and mining....which leads you back to not really making a difference
Respect

What do you think of the viability of using ammonia as fuel as hydrogen can be extracted from this and is relatively easy to store compared to using compressed hydrogen.
MAN Diesel are looking into ammonia-powered engines for ships.
I saw Toyota/Yamaha created a 455hp hydrogen engine. Totally reminded me of your channel.
This is the most concise explanation of the use of hydrogen in engines and in fuel cells I've ever seen. I've had a vague concept of this topic but this video brings it sharply in focus. Thanks!
One problem though... This is not fuel cell technology. 🙂 This is just the classic, barbarian way of exploding things inside an internal combustion engine in order to produce mechanical energy. It "just" replaces gasoline/diesel/ethanol/whatever with hydrogen.
Fuel cell technology is about reacting hydrogen and oxygen in an elegant, controlled manner, in order to produce electricity on demand which, in turn, powers an electric engine.
@@prafuitu barbaric?. If the goal is to avoid burning fossil fuels this is the best solution. Barbaric is the mining used to get Lithium to produce batteries.
@@rnp9876 I was referring to the method used to convert fuel into energy, be it diesel, hydrogen or whatever.
"Exploding" hydrogen in an ICE to produce mechanical power has roughly 30% efficiency while converting that same hydrogen into electricity in a fuel cell vehicle is, again, roughly, 60% efficient.
That's why I called ICEs barbaric in comparison to fuel cells. BEVs (battery electric vehicles) were never mentioned by me, so your argument about lithium mining is irrelevant to this discussion.
It's barbaric in the same way frantically hitting the drums is barbaric compared to gently drawing the bow across a violin's strings in order to produce sounds.
@@prafuitu EVs are not the solution. Fuel cell, probably and they are much better than battery only car, in my opinion.
@@rnp9876 Fuel cell vehicles *are* EVs, but again, you're missing the point that hydrogen ICE (presented in this video) is not the same as hydrogen fuel cells, what the top comment claims.
Anyway, to play your game:
It looks to me that you read somewhere that Li mining is bad and from that you derived that EVs are bad when you clearly don't know what an EV is.
To claim right now that EVs are bad just because the batteries technology is not optimal (when we're clearly in its early days and it has already hugely improved compared to just a few years back) is as shortsighted as saying that the ICE was bad compared to a steam engine because its efficiency was horrendous in the beginning.
Things are improving at a rapid pace, motors are becoming more efficient, alternative ways of electricity production are in development or deployed every day (check the ITER project to see the mother of all energy plants), new energy storage solutions are researched all over the globe, including alternative battery chemistries like Iron oxide or Aluminium/air ...
EVs might not be the present, but they sure are the future in either BEV form, FCEV form or any other form that we haven't even dreamt of yet!

Really, I have a WRX with mods (e.g. bigger turbo, injectors, I/C...) with 290k miles and doesn't burn oil. (acutally, I lost maybe not even half a quart in 3k miles.)
I think it's about the weight of oil you put in it. I use Rotella T6 5W-40 year around for years and no problems, beside some coolant leaks...
Wait till you hear about electric vehicles!
Thanks for your deep explanation....great job.....
Thanks for the education. Good video.
I experimented a little with converting my 4L inline petrol car to HHO, I was converting the water to gas in the car.
The two biggest hurdles I had was spare electricity, and upper cylinder lube.
I estimate about 130amps @ 12V to make a steady flow of hydrogen and run on average 2000rpm.
Upper cylinder lube could be solved by using an engine converted to LPG only.
Also if you only partial supply (I only ran 20amps@12V) to get better fuel efficiency you will need to spoof your oxygen sensor in exhaust. The cleaner exhaust will make the ECU think it running lean and enrich the tuning and won't use less fuel.
You should make a video about that.
that sounds like a headache
I'd love to hear more about this
@@willg125 I also found that I only got about 10,000km out of my plates before they had oxidized to much. I used stainless 3.16, marine grade steel. Also my water got dirty and had to replace it about every 1,500km. I had 4 litre reservoir.
I used a teaspoon of baking soda mixed in my distilled water.
hope this helps.
@@tomkeegan3782 Random af question: Want some science-channel to check out, cause the
learning never ends? I got some.
i hope mazda tries to make a hydrogen rotary race car. that would be so cool to see
I believe there is research done that showed hydrogen combined with gasoline EDIT:(2-10% combined). It is the most beneficial air- dual fuel ratio that had least amount emissions while getting an evened out and faster burn to ignite all of the fuel before it exhausts. I believe this was done In a rotary.
Are you saying that because you just thought it would be a good idea and do not know about H2 rotary engines, or because you know that Mazda has made rotaries that run on H2 before?
Mazda did make a hydrogen powered RX8 race back when RX8's where new. You could buy in Japan only a duel fuel rx8 and it worked really well actually
Woahhhhhhhh. SO THERE'S HOPE?
The rotary engine works really well with hydrogen because the inlet combustion and exhaust all occur in different areas of the chamber unlike a piston engine which all occurs in the same place in the cylinder
Best detailed and associated logic detailing hydrogen use for transportation.
If we don't get a breakthrough in battery technology soon, hydrogen is going to be our savior regarding mobile applications such as airplanes. We just need cheap electricity to produce it cost-effectively.
It’ll be a great day when engineering explained starts using the metric system
Let’s hope not
Why?
@@hubster4477 because the metric system is simply better
@@houseking9211 well how much better, and why. Look at all the huge buildings, dams, bridges, engines, etc that we've built using our system. Would the metric system make those things better, built in a shorter time, more sound design? Just asking, I would have been used to the metric system by now if around for the last 15 years.

Thanks for a very useful explanation!
Hi and thank you for your video, very useful. Is that any way to resue the emitted water from the car itself to produce dihydrogen? Does the reaction cost more energy to produce dihydrogen?
Regard
Also not mentioned is the enormous amount of energy required to compress the hydrogen to 10,000 psi, none of which is recovered during vehicle operation.
Offset with nuclear or renewable energy
Hydrogen is another pipe dream.
that is a good point, so don't do that
@@Brandon_letsgo then how would you solve Japan's energy problems?
Being a small country located in a spot with the highest incidents of earthquakes and tsunamis on the planet, makes nuclear, wind, solar, etc less viable or more expensive or just flat out dangerous than in other countries.
One of their solutions is to import energy. Electricity can't be imported from far away...and frequencies and voltages differ between countries. (Japan can't even move electricity between north and south because of frequency differences)
If not imported hydrogen to suppliment their energy needs, what would you propose?
@@tylerdurden3722 The point here is that hydrogen is less efficient than almost any alternative. So actually the answer to your question is pretty easy; do almost anything other than burning hydrogen! Battery powered cars, for example, will move more people more miles and at a cheaper cost than doing it with hydrogen. It doesn't matter how the electricity gets made. Also, Japan has a lot of nuclear reactors and doesn't seem to be slowing down much on nuclear.
Toyota: WE MUST BURN SOMETHING !
Funny!! I think the engine development teams are feeling the heat from the electric powertrain teams, No pistons, No catalytic converters, No valves, No fuel pumps or injectors, some with no transmissions…, The winner is electric!
Wrong. Toyota: we are trying 3 different routes at the same time because no one else is exploring them!
Toyota already has hybrids and it's pushing battery chemistry forward that will eventually result in solid state batteries, something that it, unlike Tesla, will be able to disseminate widely. It's also one of the few automakers working on fuel cells, which will arguably supersede both batteries and internal combustion engines even when taking emissions into account.
Due to embodied emissions of production, battery EVs have higher life cycle emissions unless they charge from electric grids served primarily by nuclear or hydroelectic power. Even with so-called "renewable" grids, the emissions are produced by backup gas turbines. The end result is that unless a BEV is charged from a low emission grid it will also have a lifetime that is high emission eventually. It's one of the reasons why an electric car is greener when running in one of the Scandinavian countries, because that cross-country grid has a backbone of hydroelectricity from Norway, nuclear power from Sweden and wind power from Denmark. But it's not so green when running in California which burns and fracks gas for most of its energy.
Arguably, the lowest emission vehicle possible is an ammonia fuel cell vehicle using ammonia produced by electricity from a nuclear and hydroelectric grid. That vehicle will be low emissions in operation and embodied in production and disposal. And it would be more fully recyclable, than the carbon fibre composite fuel tanks a hydrogen fuelled vehicle would be. Right now composites are just dumped in landfill, something that Denmark and its kilotons (and in a decade, a megaton) of wind turbine blades are finding out to be a bit of an issue.

This is a very interesting educative video presentation. Would you please make another similar explanation video to use DME in a typical Diesel Engine as a hypothetical replacement for diesel fuel (?) I heard that Volvo Team has introduced Volvo Truck run by DME.
I think we all know companies will find a way around all these problems and challenges
I recently saw a video about JCB in England, they have been experimenting with hydrogen combustion engines in their construction vehicles. From what I saw , they have basically redesigned the cylinder heads for their Diesel engines, and they can now run on hydrogen!
Well I spoke to a JCB engineer in the beginning of Nov 2021 directly involved in the battery section of JCB and stated their hydrogen direct injection engine isn't real viable due to the huge amount of fuel required, however their Fuel Cell is very efficient, using 80ltr of hydrogen for 8 hours of work on a 16 tonne excavator but that's not JCB system and the cost of the system was huge, at least the cost of the excavator! So they are actually going down the battery route but cant tell anyone as they get huge grants from the UK government
That was a uncritical puff piece for JCB.
JCB also make battery powered diggers that make sense. Incresingly, these quiet diggers will be required for night works in residential areas.
@@tatradak JCB has had a battery digger for a year now.
@@nordic5490 JCB said that small excavators are a better fit for batteries because most of the small excavators are not used for more than 4 hours in a day. The use of batteries in large excavators is not cost-effective or even feasible at this time.
The 20 ton excavator it's not viable in it's presentation , behind it there is a £150.000 container ( the with the same colours as the excavator) filled with hydrogen and a built in pump that is barely able to sustain the refill for that single excavator for half a day work.
The developing of that engine is just free publicity as it's 100% funded by the government.
At least they’re trying. ‘Rome wasn’t built in a day’.
Good luck ‘trying’ against the laws of physics.

EXCELLENT VIDEO ABOUT HYDROGEN BURNING IN ICE ENGINE. PROBLEM LIKE NO AND CO2 WERE NEVER TALKED IN OTHER VIDEO. GOOD JOB KEEP IT UP.
That was awesome. Well done!
In an interview on of the Toyota’s engineer mentioned the whole thing can be scrapped but they wanted to give it a try at the endurance race, Toyota opened the door so it’ll be interesting where it goes from here
Toyota had prepared lean-burn engines as an alternative to catalytic convertors….the precious metals market ensured govts ignored them and introduced the legislation that guaranteed them a huge income and a superb technology got buried. Battery industry are doing the same right now to petroleum products and will destroy their main green competitor hydrogen too.
@Alfred Wedmore Lean burn spark ignition is great for economy and mitigating HC and CO but it does nothing good for NOx. Back when those engines were developed this was ok because the NOx emissions limits were relatively high. Once the requirements for NOx emissions became more strict it became impossible to meet them with lean burn engines, stoichiometric mixture and a 3-way cat was the best approach. As an aside, some modern automotive engines do use lean burn under certain conditions, it's just not applicable across the entire load/speed range.
Just to prove the point, diesels are intrinsically lean burn and thus can't use a 3-way cat. Initially this was allowed for by giving them looser NOx limits (and tighter HC and CO limits, which could be met using an oxidation catalyst) but these days they need the much maligned EGR and SCR systems to meet their NOx limits. A lean burn spark ignition engine would need the same equipment, though depending on the design it might be able to dispense with the DPF that diesels need to prevent soot emissions.
@@nerd1000ify This person spreads truth instead of conspiracy theories. There are plenty of real live conspiracies, no need to go looking so hard for them.
@Alfred Wedmore Wrong. The cats are there to protect the environment. All the sensors and the computers in your car are there to protect your cats! Why? Because the catalytic converter is your last line of defense against the harmful gasses that will destroy your planet.

This is Excellent news. I have always wondered why no-one was trying to run Hydrogen in a combustion engine. Thanks for the info.
Peter Ross the impediments which the oil giants have been putting on hydrogen...and electric...vehicles over the last 100 years is absolutely mind-blowing.
I love next gen technologies that involve even more moving parts!
Only thing missing is fuses placed in the center of the engine.
Right. I just did a timing job on my Ford 281ci. A lot of work and moving parts. How about a cylinder and some spark with electronic timing?
More moving parts = more jobs 😄
And also use a fuel which isn't actually renewable (electrolysis isn't cost effective, almost all hydrogen is made from oil), green (still has emissions) and in general is just a campaign by fossil fuel and engine manufacturers to avoid becoming irrelevant.

Great info thanks
James May from Top Gear said it best: "the problem is that hydrogen is attached to other stuff." A very understated remark because it is indeed, and takes a lot of energy to split it off by itself. This is what everyone's ignoring. It's like someone saying that they're building flying saucers, counting on someone to hand them an anti-gravity devices to make it all work. The devil's in the details.
Great explanation. The drawbacks of hydrogen were looked into years ago. The fuel cost alone will deter people from buying a hydrogen car. Then you have the massive infrastructure cost.
Hydrogen use with fuel cell engines is the only absolute solution though. It may be expensive right now; but much better choice than ruining the atmosphere and ruining the Earth. Its emission is water !
@@gokcan83 It is better but better doesn't mean it is viable. Do you think people will be motivated to buy a hydrogen powered car when they learn about the expenses involved? Unless something can be done to reduce cost to a reasonable level this won't take off.
@@abinmmj the US Govt, federal and state, subsidizes the oil and gas industry to the tune of over US$20 BILLION per year. Transfer those subsidies to the hydrogen infrastructure instead, and hydrogen becomes a viable fuel option.....
@@abinmmj Hydrogen will be use for all of Transportation, including semi-trucks, airplanes, cruise ships and powering houses. Don't worry Hydrogen is not going anywhere now
@@ianchandley So you say. Devil's in the details (and line items).
For old cars, the best option is LNG or LPG. That would lower Co2 emissions by 20%-50%, relatively cheap installation, and proven technology. I drive on LPG for decades. Driving is 50% cheaper ROI for installation is from 8-18 months.
cng is dirt cheap on the markets. As low as 10c per kg. But that low price for now doesnt reflect low price on the pump stations.
It comes with its own issues. If you simply convert a petrol car to CNG, it's only a matter of time until the valves/seats get toasted. Factory converted CNG cars all have hardened valves/seats. CNG was also heavily subsidized in my area, but once that stopped, CNG cars just faded away after a while (I drove CNG cars for years, btw).
@@prerunnerwannabe With modern (last ten years) installations that are not an issue, they can be programmed with a few percent of petrol added in the mixture for protecting injectors, and valves. For very sensitive and complex motors lubrication is added in intake. In my country is very popular almost every station has LPG.
Converting to CNG is actually a super popular option in India, there are a bunch of companies that will convert your car to also have a CNG tank, and it's pretty convenient because we have a lot of CNG stations as well since most autos also run on CNG (auto: tuk-tuks or rickshaws, basically a three-wheeled vehicle, that is a common mode of public transportation).
The valves/seats problems comes from keeping gasoline as additional fuel ( Bi-fuel option) . The gasoline has much lower octane rating than LPG and CNG so it do not allow increasing of compression ratios which increase the speed of burning . In South Korea pure LPG cars are used with liquid injection of LPG which even increase the power if compared to equivalent gasoline engine .
The measures to convert gasoline to pure LPG or CNG engines are :
1 . Increasing the compression ratio 12:1 14:1
2. Using high energy ignition systems 100mJ and up per spark discharge and use of double tips iridium spark plugs .
3. Remapping the ignition and fuel maps of the ECU .
4. Replacing the exhaust valves seats with tool steel made ones and if possible use of sodium filled exhaust valves .
There was experimental fuel mix mainly CNG with small amount of hydrogen. Hydrogen burns very fast , ignites by much lower energy spark discharge and accelerate the rate of burning of the mixture so it is another way to solve the problem with slower CNG burning speed.
early days, consider what we had for when the batteries (lead acid) and electric motors were at the time. using H2 in a car is still pretty new
normal Carb engines will run hydergen out of the box only needs minor mods to fix backfires
Hey, great video 👍
I’ve read about BMW trying to solve the emission problem due to the engine oil being burned, by using ceramic pistons, which don’t require lubrication. 🤔 but they stopped the further development
as explained the emissions would be negligible
Your videos are always out of this world, thank you for encouraging me to be mechanical engineer

Good job! thanks for the info. I always wondered about this. Maybe a gas/hydrogen hybrid electric? lol
Fascinating explanation, really enjoyed this! I used to think hydrogen fuel was a no-brainer for sustainability but it's not quite that easy. As usual, thank you for the awesome video! Nicely executed, well articulated.
It's no brainer if you have no brains. Why waste most of the power produced on an inefficient process that roduces an inefficient fuel which which produces insufficient power? Also, you have to carry around two heavy H2 tanks containing the gas at such high pressures that a smile accident can cause them to both explode due to pressure and ignition. Definite death. Even a simple leak in any of the piping is enough to cause trouble, which is bound to haen due to the excessively corrosive property of H2.
Actually you don't need to store hydrogen in tanks. They have developed technology that is far safer. It's been around for quite a while actually. But yes if you just got out of a time machine from the year 2000, then that would make sense.
@@Berkhoi Apart from the points that you have raised, the real problem is that the energy used to compress the hydrogen alone can exceed the calorific value of the fuel. This makes the whole concept virtually pointless. Needless to say, I would not want to live too near to a filling station and tankers delivering hydrogen compressed to an excess of 10,000'psi would be travelling bombs, even without any fire.
Back in WW2, when fuel was short here in the UK, many delivery vans ran on coal gas (97% hydrogen). However, a large leather bladder was fitted onto their roof, to allow direct filling from the town gas supply only pressurised by the gasometer's.
The natural coal tar mix improved combustion and lubrication, but the bladder was almost as large as the van, with a range of between 20 and 30 miles.
PS, the risk of combustion explosions with hydrogen is fairly low compared with LPG. Propane (which is heavier than air) pools and causes fire balls. while Methane diffuses and explodes. Both of these gasses have caused explosions after leaking into below ground sewers.
@@wilsjane the real problem is too many people and pop growth is rising exponentionally !@
The more work goes into every step of the process, the cheaper and more effective it gets.
The early days of gasoline, diesel and even electric were not pretty. Took time to get to where it is today, and be as cost-efficient as it is, at scale.
The important thing is to take steps to make that progress, and innovation will follow.
100%. Scale is the biggest factor in price
well i hope this will help save the planet !!🤣
The efficiency will not change though. These are theoritical maximums. You will never be able to gain more efficiently from combustion. Physics says NO!!
Plus why lose half of all your energy turning a transmission, driveshaft and differential when you have a much more efficient example: a hydrogen fuel cell that powers a motor right at the wheel station.
This technology makes no sense.
It is just a pipe dream being pursued by existing engine manufacturers like Cummins to keep themselves in the game.
The writing is in the wall. They need to embrace change and research sensible technologies that have potential, instead of trying to adapt old technology.
@@bubba842 Why can't all these technologies exists simultaneously and then the consumer can make the decision for themselves regarding which type of car they want to buy? They just completed a 24 hour race with the car so the tech makes sense, its just not what you want in your car. Why do you care where Toyota puts their money anyways? If you want the most efficient vehicle, you can go buy that vehicle. Enough with this holier than thou stuff about sensibility and embracing change though, its too cliche.
@@collinhruschka8441 it's called business pal no holier than thou sensibilities. All these technologies will exist to an extent, but for the purpose they are required in.
We will not have multiple technologies competing. Hydrogen fuel cells are cheaper and a lot more efficient than this technology. The vast majority of people will go with what's cheaper and is more efficient. Unfortunately neither of those technologies have an edge on Battery EVs. Yes hydrogen fuel cells will have their place in long distance and off road technologies, but every day people who commute will be driving EVs.
There is room for this in the future in very niche areas, but those areas will not produce the revenue for a mass rollout of this technology to the mainstream, as it's just recycled old technology that will never get past the physics and downsides of combustion.
The infrastructure is not in place for this technology and probably never will be. It will use twice as much hydrogen compared to a hydrogen fuel cell vehicle and will have a tank twice the size of today's gasoline fuel tanks. With that it will cost twice as much to fill up.
I don't see any positives for the average person in using this technology. The only positives will be for legacy engine manufacturers, trying to hold on to a dying industry, hence why they are pushing it.
The nature of the business environment will not allow multiple different technologies to exist all at once.
There are many examples of this in the past. AC vs DC electricity, VHS vs Betamax and HD DVD vs Blu Ray.
A standalone entity will survive, but unfortunately it will not be this hydrogen combustion.
The combustion engine must live on !
In the eighties high school I went to converted Briggs and Stratton lawn mower engines to run on propane, butane, hydrogen we even ran one off of acetylene.
I love that most things can be figured out by the numbers first before energy is wasted.
Love when real plans come together in an effort to go into correct direction more expediently.
Nice work and video.
It makes sense if you convert the power grid to nuclear power.
Here in the UK, the planned conversion to electric vehicles will require 10 additional power stations. Plans are to build more wind farms.
However, the grid infrastructure is a far more serious problem and will require extensive upgrades. As recharging becomes faster, charging areas will be supplied from the 11'kV high voltage grid, rather than the low voltage sectors.
At the moment, the government are promoting electric vehicles, since the change over to regenerative AC motors on the railways, along with LED lighting and induction cooker hobs has reduced the grid load quite considerably.
In the future, the government expects to slow down the sale of electric vehicles to keep the electricity requirement in balance.
@@wilsjane Sounds like ride sharing, mass transit and reduced car ownership with Uber, Lyft et c will get a boost. As may thorium reactors for electricity. If personal ICE cars were closed course only, humankind will be playing more video games and gain 100 lbs per person. Not to mention noise, electrical leakage, and fire risk from 11kv lines. Yuk.
@@wilsjane The UK had planned on Ireland to offer green energy but that might go to France now. However the hydrogen dream is not over in the UK, they will be injecting hydrogen into the gas supply network and rolling out hydrogen ready gas burners for home heating. How will they make the hydrogen? probably wind farms at sea that convert the sea directly to hydrogen and dont need any expensive batteries.
@@geroutathat That makes a great deal of sense, avoiding the losses of conveying the electricity inland from offshore wind farms. The oxygen produced by splitting the water will be a valuable biproduct.
Prior to the discovery of natural gas in the 1960s, town gas in the UK was mainly hydrogen, with a small percentage of carbon monoxide. It was produced by heating coal in a vertical retort and the coke then went on to fire the power stations.
The one problem is that hydrogen has a lower calorific value than natural gas, so some upgrades may be needed to the distribution pipework. This is because following the changeover to natural gas, the crumbling cast iron Victorian pipework in the cities was used as ducts to install the natural gas pipes, thus reducing their size by up to 50%.
We may also see a return of the famous gas holders that were used to smooth out the peaks in demand. Possibly the hydrogen will be supplied at higher pressure than previously, avoiding pipework upgrades.
Hydrogen to directly power vehicles is a non starter, simply because it does not liquify. This results in huge energy wastage in compressing the gas for distribution. From production to final use in a vehicle, around 70% of the energy is lost as a result of compression for distribution and into the vehicles fuel tanks.
@@wilsjane EV's are the scam of the century.
They could not be more harmful to the environment.
Countless tons of rare, toxic metals must be strip mined and processed with vast quantities of toxic chemicals in order to manufacture batteries which will become yet another source of various toxic waste streams. Even if these waste batteries are "recycled", doing so will require more toxic chemicals and huge quantities of energy.
The mining and processing of these rare, toxic materials requires vast quantities of energy in remote areas with little to no electrical infrastructure.
We currently do not have enough electricity production in places like California to keep up with the current demand that does not include having EV's replacing gasoline and diesel vehicles. Already high electricity prices will skyrocket as more EV's hit the roads.
Hydrogen is a much better path forward.
First of all, the high efficiency of the fuel cell comes from a long R&D process which took place over the course of several decades. I would not be surprised if the HCCI engine (which already is at 45% efficiency) could go through the same process, perhaps even with a better efficiency than the fuel cell at the end of it.
Then, the hydrogen can probably be produced using solar-powered thermal reactions in countries with high temperatures; I imagine a future in which countries which now produce oil instead produce hydrogen, which has the advantage of being able to be shipped to other nations as an energy source. (Note that the U. S. and China would be some of these countries, as would be Spain.)
Thirdly, the large tank size, as well as the 4h refilling time, can be remedied by exchanging the entire tank at refilling stations. This will reduce the total refilling time 7-fold.
Well said. From what it sounds like formula one will be almost zero emission by 2030, and in order to do that there needs to be an abundance of wind and solar energy to pull hydrogen from water and then to store and ship.
Solar lmao

@@GgDBXS No, I was referring to the tendency of Hydrogen to form very explosive mixtures with air. So a small leak and very tiny spark can lead to a proper explosion

Random af question: Want some science-channel to check out, cause the
learning never ends? I got some.
Why? What's so exciting about hydrogen? You can't just stick a hose up in the air and extract it.
@@mjoet731 the attraction to hydrogen is that its the most common element on the planet and we spend our entire life surrounded by it. It presents a 100 percent renewable source of energy that would never be exhausted and could potentially be produced wherever it needs to be used eliminating all the expense of transportation and distribution. Hydrogen on demand.
The way this guy presents everything is made to convince the listener that it looks promising but somehow it’s just not possible, sorry!
The reality is he is a paid detractor as many people on you tube are. There are many technologies that are possible for the betterment of mankind but some people wish to control the world and if a technology creates freedom for others out of their control then they find every way possible to stop it. One of the most effective ways is to hijack a movement or technology and redirect to more controllable circumstances. It allows for the masses to believe something never went anywhere because it was just inefficient or “uneconomical”. When the truth is it allowed to much freedom from the control of those who benefit from manipulating the population.
Now if they could find a way to profit more off of hydrogen than oil or electric then we will be using hydrogen in the future. But until they find the perfect way to keep control while allowing people to use hydrogen. We won’t see anything but misdirection and manipulation of statistics.

JCB are doing it too, Harry's garage made a great video all about it
Both Mercedes Benz and BMW had working ICE engines during the 70-ties as well as there were some converted ICEs in US for test purposes. One thing, not mentioned is that stoichometric combustion of hydrogen and air will result in such high temperatures that the nitrogen oxides are produced in large quantities (order of 5 - 10 000 ppm) since there is no carbon source it can not be catalyzed away as in peterol engines. The solution is to use lean fuel mixtures (approx 50%) in purpose to reduce the combustion temperature in purpose to avoid NOx formation. This results in a much lower specific power which can, in turn, be overcome by supercharging and/or an increase of engine rpm. An alternative tested was water injection into the combustion chamber in purpose to reduce the temperature. MB had both hydrogen fueled small buses and traditional sedan cars. To my knowledge most of these projects has been terminated.
Finally someone pointed it out!
Fabulous presentation. Thank you, Jason.
Everyone forgets bmw did this with the E38 7series. It had a hydrogen powered V12.
Exactly my point and I believe angelina jolie had one too 😂

Probably a mix of both
I've found if you just open enough tabs you can learn all kinds of stuff. It's a mix of both! In this case I'd heard about the engine a while back when they'd announced they were racing it, so I asked Toyota if I could use their engine animation and they sent it. :)
One thing you didn't consider is that there are such huge surpluses in solar energy production, at times, that they have to shut down the solar plants. They could generate an enormous amount of hydrogen, and it would cost practically nothing, since they would be tapping surplus (unused) energy.
Do you have a video on the five cycle motor, I heard something about it being the new thing
The first combustion engines were also extremely inefficient.
Over time, ICE H2 engines will become much more efficient.
