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.”

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.

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.

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.

@@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.

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!

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.

You're making a few important assumptions, and missing a few steps. As the video illustrated, hydrogen combustion itself is a dead horse, even with much higher pressure you can't bring enough hydrogen with you for it to be practical, and even at 700bar refilling is already so impractical that for every 7 minute refill, the station has to re-pressurise at least 15 minutes, meaining you can do at most 3 cars/hour/station. Which is less than a fast charger, which has a net higher energy efficiency to boot (not just the hydrogen takes a lot of energy, the infrastructure as well, like compressors, whereas that kind of stuff is minimal on electric). Purely on the rarity of energy alone hydrogen makes little sense. Another assumption you make is that the material shortage isn't an issue for hydrogen. It is an issue. FCEV's use a boatload. Not only because they essentially are EV's (the fuelcell can't "spike" as hard as a battery can, so every FCEV has a battery to boot, which albeit smaller, is still sizeable), but also because the fuel cell has a lot of rare, expensive materials in it. Heck, it has platina as a frigging consumable. Considering you can't get 700 bar of hydrogen on your driveway, but you can get AC current which you can easily load balance on top of it, and battery chemistries are not only diverse but constantly evolving (energy density doubled, and LFP is a no-cobalt viable technology already), and considering "vroom" even for hydrogen makes no sense... I'd say hydrogen and sustainable have no mix in personal vehicles.

[@nerd1000ify]

@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.

[@flappingflight8537]

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.

@@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.

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.)

Many scientists and countries are investing in H2 for many reasons, not for just a report or a single quote.

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.

[@Justbetru]

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.

It makes sense if you convert the power grid to nuclear power.

[@wilsjane]

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 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.

[@wilsjane]

@@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.

[@MichaelMorgan1979]

As i'm sure you are aware electrolysis produces both oxygen and hydrogen, I wonder if its possible to make an engine that runs by combusting the mixture directly. For example you have an O2 and H tank in the car and mix them in the cylinder at the correct ratio. Chances are I'm talking nonsense but just a wild idea.

[@ytcane6326]

You should do a video on using ammonia as fuel for and ICE (or fuel cell). I've seen a bunch of articles about using ammonia produced with renewable energy to store hydrogen eliminating the need for the high pressure tanks.

[@UnnamedThe]

I'm not letting "HCCI is difficult to control" count, because people have been cursing common rail injection as well, and now it's a staple in diesels. It's all a matter of development. I'm proud of Toyota for trying stuff here.

[@IJMacfarlane]

I think it's because the properties of hydrogen are very different from diesel fuel.

[@IJMacfarlane]

@@UnnamedThe Ah, I see your angle now. Good point.

[@EngineeringExplained]

That's fair, but this stuff has been researched for decades, and still not really any commercial applications. Lots of companies (VW, Mercedes, Nissan, Mazda, Honda, Hyundai, GM, and on and on) have put effort into research/development, but decades later still not large scale applications. Mazda seems closest with their SPCCI engines, but even that has been delayed for US release.

@@EngineeringExplained BEV's where also developed for decades before they became viable. And i'm sure we all know how long safe nuclear power plants too to develop. Long development time does not necessarily mean the potential can't be reached.

[@kurtbilinski1723]

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.
