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.”

At Toyota "Guys, I think it's time to admit that internal combustion engines are not the way of the future" Other executives "We would rather die honorably. Throw everything we have into developing an internal combustion engine that is classified as carbon neutral."

I heard on another channel that a former NASA scientist has a plan to use ammonia as a liquid fuel for a hydrogen combustion engine. The system some how separates the hydrogen atoms from liquid ammonia and exhausts the extra nitrogen. That system would eliminate the need for high pressure tanks for hydrogen and speed refueling. Could you please research this and do a video on why or why not this could work? Thank you. Great channel BTW.

IF Toyota believes so completely in hydrogen, they need to do what Tesla did - front build the infrastructure to support the vehicles, THEN sell the vehicles. It’s a matter of put up or shut up. So far, I’d say Toyota needs to shut up.

Hydrogen fuel is RIDICULOUS! It takes more electricity to produce the hydrogen than an electric car would use to drive the SAME distance! Electric vehicles CAN BE charged ANYWHERE electricity is available. Hydrogen requires SPECIAL filling stations of which there are virtually NONE and are EXTREMELY expensive to build due to the nature of hydrogen!

Oh please. Energy output on the industrial level to produce hydrogen is way higher than the crank output. It's called the law of thermodynamics. Carbon footprint be damned, it's provable. Real solutions involve the abandoned technologies. Chemical reactions for the mechanical. (NO alcohol. I'd rather EAT corn.) Reclamation reactions for the electrical. Diversify. It isn't hard. All CO2 neutral btw.

Just watched a fluff piece for JCB equipment talking about their I.C. hydrogen fuelled engine. Lord Bamford was very effusive about his engine for heavy equipment and how it does not inflate the cost and weight of the machine batteries and fuel cells do. I recall some years ago it described that long haul transport would have to have a fuel tank the size of the trailer to achieve the same type of range they do with diesel. I'm some what puzzled by the conflicting messages.

Hi, If we could find the way to separate water molecules (H2 and O2) could we fuel the car with "tap water"?... after separation we could use the Hydrogen AND the Oxygen both to combust the engine (mix free from N2), this way we get water/steam at the end of the pipe (No NOx). I've always been fascinated by this option, as electric tech seems (to me) to be not green (emissions in long run are unmanageable, and electricity production will demand and dispose a lot of natural resources and toxic components) not to mention and most important electric circuits blast our bodies with Electro magnetic energy all the time like cell phones do (I heard electric fields are no good for our body, and nobody seems to deny or care / tesla & co.).

If the same amount of money was invested into this technology as electric, I'm sure it would be a much better solution considering how wasteful EV's are after they exceed their lifespan.
jonathan mcdaniel
Although I view H2 fueled vehicles with a healthy level of skepticism, I agree that battery based EVs are a dubious approach to consumer automotives. H2 fueled vehicles have a higher likelihood, with some modifications, of replicating the processes and systems that support hydrcarbon based transportation. This makes it a viable alternative, although I believe a fuel cell based vehicle may show more promise. Aside from some specialized applications EVs lack viability. EVs on the road now wouldn't be there without government subsidization. And scaling up EV capability (mostly battery capacity) to that of ICE, expanding it beyond a niche market, and developing a dependable recharging network will prove to be an unreachable goal. The materials for constructing the EVs is probably the first limiting factor.

After people got wise to the big oil and the auto manufacturers’ hydrogen fuel cell red herring… now this nonsense. No effing thanks. Wastes way more electricity for electrolysis to get the hydrogen fuel. Just put less electricity into a battery with a current electric motor/controller to get the same miles driven.

I am confused about the Natural Gas comment, Natural Gas is the most renewable fuel source we have, it has a very short production time and can be harvested from waste product. As for turning it into Hydrogen to burn in an Engine, that has limited appeal. Most Vehicles will be BEV soon enough, the few who remain behind can continue to enjoy their history with little Global Effect.

Recovering dead body? More running parts, more costly to produce than EV. Are they nuts at Toyota? Since I have EV I'm surprised who wants to drive old tech since new is much better.

Hydrogen seems more promising than electric to me. However, everyone pushing electric cars without a plan for meeting the demand. Without a clear plan it will cripple power plants, increase prices on energy, and create lines at charging stations just the gas shortages in the 1970s under the Carter Administration. Electric cars do not have the range no ease of refueling as internal combustion does. So you're in effect limiting a person's freedom to travel. Until a realistic plan on implementation with a real infrastructure plan is presented that is attainable I will stick with my gasoline solution.

The problems with hydrogen are due to the laws of physics, not the oil companies, and not republicans in congress either. H2 is a cryogenic gas, meaning it doesn't liquify at normal temperatures and pressures. So storing a useful amount requires compressing it to very high pressure, up to 10,000 psi. Compressing a gas itself is inefficient, as up to 75% of the input power to the compressor is converted to heat. That is why your 4hp air compressor's output can barely power an air tool the size of an electric toothbrush, and why it's output pipe gets so hot it will burn your skin right off. But there's more. A fuel cell that recombines H2 with pure oxygen is very efficient, just like electrolysis in reverse. But fuel cells in cars recombine the H2 with AIR, not pure O2. So car fuels cells are only about 40% efficient at recovering the energy in the H2. And an internal combustion engine is even less efficient, converting maybe 30% of the fuel energy into mechanical power. Ultimately just using the same electricity to charge car batteries instead of converting it to hydrogen, will result in the battery powered car going about 4 TIMES further per kilowatt-hr of input power. It does make sense to try to repower the millions of existing IC engine cars with hydrogen. But a far better idea is to use Ammonia. Ammonia is mostly hydrogen. It is far more energy dense than compressed H2 gas, it liquifies at only a couple hundred psi, and burns readily in an ic engine. It's downside is only... the lethal toxicity. Hmmm, I guess we just can't win.

Ya see the reason is so hard to beat Gas or diesel in a combustion format is that they're already very good at it. Relatively speaking they're pretty efficient and environmentally friendly anymore. Personal vehicles (those being cars and trucks/gas or diesel) making up the smallest amount of global greenhouse gasses produced and all. An Electric motor is arguably better if you ignore all the problems that come along the way. If you're gonna use Batteries you'll most certainly end up causing more environmental damage then if you hadn't. Using lithium batteries is problematic for many reasons for example production and total life span. A modern battery in a tesla for example wont last more then 10 years without significant problems. Which wont be a problem assuming you've got money. However I did hear they were planning on welding the batteries to the chassis rendering them permanent. We've gotten a good example of the current state of hydrogen fuel cells and engines. Looking forward to seeing what happens with them but obviously rn they're not a remote consideration. I do find it odd that they're bringing out electric cars and proceeding to force everyone to buy them. With laws, bans on gasoline and diesel vehicles and other such things making them less viable by the day. With no real evidence to support the changes. Seems like a pretty SOLID business model. Almost too SOLID

1 quart of oil every 3,000 miles in a modern engine seems way way off, this is almost 1 litre of oil every 3,000 miles. For context my bmw 530D uses under 1 litre every 17,000 - 18,000 miles, as it gets to the end of its life it starts to burn off. One litre is about the difference between the high and low marks on a dips stick. JCB are investing in hydrogen engine tech, I suspect the tech is far better than portrayed in this video.
