Why Hydrogen Engines Are A Bad Idea

Hydrogen combustion engines won't exist in the fuel cell & EV future.
How Hydrogen Piston Engines Work - • The Difference Between...
How Hydrogen Fuel Cells Work - • Hydrogen Cars - Toyota...
On the surface, hydrogen combustion engines seem like the ultimate solution for car guys. You still get a wonderful four-stroke piston-cylinder combustion engine, with the sound and feel you've come to love, but all without any carbon emissions. Since hydrogen fuel (H2) doesn't have carbon in it (like gasoline or diesel fuel), there's no carbon added to the byproducts of combustion in a hydrogen engine. It's just as good as it sounds, but unfortunately there's a much more logical alternative that makes hydrogen engines seem quite silly. Check out the video for all the details!

[@uru-freemind7711]

the best engine is the electric one since its energy travels by cables not by trucks and boats that consume more fuel with an efficiency that does not even reach 40%, also because fewer parts are needed gearboxes, spark plugs, starter batteries, clutches , sensors, air filter, fuel filter, oil filter, catalyst etc, which means to spend less energy in the manufacture and transportation of all those parts. Electric vehicles pollute less because they do not discard as many parts during their useful life and waste control would be simpler because recycling the batteries and having to declare their replacement would suffice. It would be much simpler and more efficient to use oil, natural gas, hydrogen etc in power plants and from there feed the EV since the stationary engines are more efficient and it is not the same to take the fuel to a point in the territory and then the Energy trip by wires that take it to all the gas stations. And heat treatments and melting so much metal for combustion vehicles spends a lot of energy.

[@YaketyYakDontTalkBack]

So... You're saying I won't be able to convert the engine in my classic car to run on hydrogen, because I was hoping for conversion kits? Now I have to swap in a fuel cell at best or go electric? @engineeringexplained

[@BenMitro]

@@ME-kp5iz while that is true, keep in mind that battery technology is pretty much in its infancy - there are many chemistries being explored at the moment - efforts focused on reducing cost (by using more readily available materials), reducing wieght per KWh (which will improve efficiency of EV's), improved charging speed and improved safety, both during production, during use and eventual disposal. We will make many mistakes, and I expect we will have a few breakthroughs in the next decade, and possible overcome many shortcomings of battery technology. Currently hydrogen production, transport and use has its fair share of unacceptable environmental impacts too (and being improved). One thing that is certain, as far as I can see, is the fossil fuel powered vehicles is going the way of the dodo slowly. Which technology replaces it? - exciting times!

I could see a future where both systems are a thing, and that's by design. We could have fuel cell cars be the "people carriers", no gears, fully autonomous at some point, all that jazz. As Hydrogen ICE these could replace gasoline ICE engines for enthusiast vehicles - so there'd be a very true separation between "cars" and "sports cars", where the sports cars could be more focused when not strangled by emissions, by a way of introducing NOx capture devices or running the fuel lean. Sports cars could become a true niche of it's own, used for purely sporting purposes and not considered A to B transportation, owning a sports car that you drive yourself, change gears yourself and create noise with would be more akin to owning a jetski - it would be a leisure toy, stripped of it's previous function. I don't know if this makes sense to anybody but it's my two cents

For performance vehicles I think you'd just put a bigger battery on the vehicle, or even have it exclusively battery-powered. EVs haven't had nearly as much R&D time put into them as petrol ones yet still there are relatively affordable battery EVs that have crazy good performance due to how electric motors get that instant torque. FC could work too as long as the technology improves a lot. Would still use _some sort_ of battery or capacitor system but wouldn't need to be too large if it was a really powerful advanced fuel cell.

Heat engines, including the efficient Stirling, can be made of iron, including stainless-steel. Iron is an abundant component of the Earth's crust, and is the 5th most abundant element in the crust. No mining of exotic scarce metals. Mining the lithium for our lithium batteries, is harming the water supplies of the people who live in the Andes mountains. Stirling, Otto and Diesel engines can run on ammonia fuel, easily made from water and air,by renewable-electricity. Fueling stations can quickly & easily be converted to ammonia fuel, which liquifies at around 200 psi. We already have a widespread infrastructure to make, store & transport ammonia. Belgium converted their buses to ammonia-fuel in WWII, and it took only 5 months. But Stirling engines, being external-combustion engines, can easily cleanly burn any fuel, including ammonia or biodiesel.

There are already those same NOx emissions coming out of normal gasoline vehicles, and with the subtraction of carbon emissions, they could prove to be a great alternative.

Your explanations are all true, except for financial considerations. Yes, a fuel cell is twice as efficient as an IC engine. I worked for the leading fuel cell manufacturer for 10 years. Our city buses before conversion to Hydrogen fuel cells cost $325 thousand each. After converion $3.5 million each! Now these were 100% Hydrogen power, no hybrid battery involved. It is ten times more expensive if you compare Kw to Kw, Hydrogen to IC piston engine. The diesel busses converted to Hydrogen diesel would have cost perhaps $500 thousand each. As you can see the Hydrogen fuel cell as a large industrial vehicle power source is not viable. The non-renewable Platinum catalyst alone for one of these busses is $350 thousand. Your arugument is interesting, but not applicable to the actual real World.

​@@nagyandras8857 Large wind farms and solar fields of sufficient size should have ammonia-producing factories built on-site. They'd have easy access to large amounts of the power generated, and when there's peak power production and not enough demand, they could produce ammonia. Raw hydrogen itself is not very useful as a fuel source, it has none of the properties you'd desire for a fuel source, it's a low density, highly volatile gas that can escape almost any containment, and will frequently damage and embrittle the containers themselves. Ammonia, on the other hand, is fairly non-volatile and low toxicity compared to other liquid fuel, it can be stored in almost any container, and is reasonably energy dense at atmospheric pressure. It's also an extremely valuable fertilizer component, so simply having "green ammonia" available on the market would reduce fossil fuel use elsewhere. While hydrogen is still a key component here (being needed for the Haber-Bosch process), the transportation sector would be better served by having ammonia-burning PHEV's. Pure ammonia combustion would be less efficient well-to-wheel than hydrogen fuel cell vehicles, but that could be easily offset by having the battery-electric functionality that a PHEV vehicle posses. An ammonia-PHEV with 50km+ range would satisfy the daily driving needs of most of the world, and the infrequent times when that range isn't adequate, the NOx emissions per-vehicle would be acceptable. Cities and towns could ban *running* combustion engines within city limits, and engine use could be restricted to highways away from urban centers (where you need to use the engine, anyways). There's definitely potential within the broad "hydrogen economy" scheme, but hydrogen fuel cell vehicles are a waste of time and resources, governments should abandon support for them, and eyes should turn towards ammonia combustion in the short term, and direct ammonia fuel cells in the long term, if such a thing is viable.

CO2 is plant food. The atmosphere barely has enough to keep plants alive. Also, CO2 is a very negligible "greenhouse gas." The number one greenhouse gas is WATER VAPOR, and it's ALWAYS going to be there in such vast quantities that the effects of all others are negligible. That being said, just as an oven's temperature is controlled by the heat source, not the insulation around the box, the EARTH's overall temperature is controlled by solar output, not the atmosphere. All the atmosphere does is minimize the difference between the daylight side and the night side. Venus isn't insanely hot due to CO2 in the atmosphere, it's insanely hot because it receives 9/4 as much sunlight per unit of area as the earth does. The temperature of the Earth's surface, overall, is approximaately 300 Kelvin, and that of Venus around 700 Kelvin.

It is not a simple way to convert them. It's not just to put in different injectors, and thanks. Hydrogen burn hotter and that demands more of the materials exposed to the combustion. And getting water vapor and hydrogen blowby (from piston rings not sealing 100%) into the oil is not good either.

[@Harfie]

I think that hydrogen combustion engines are indeed a good idea. First off, they are significantly lighter than a fuel cell, just like how a standard engine is, and are still able to put out just as much torque as a diesel engine. This is very much necessary for large industrial vehicles (that are already ridiculously heavy) since installing a fuel cell or a lithium battery pack would increase the weight by a significant margin, making them inconvenient and unusable. Another plus is that with the production of hydrogen combustion engines is that thousands of people wont have to lose their jobs and be forced to find a different line of work, since batteries and fuel cells are so dramatically different in structure and production than a combustion engine. It definitely has its uses, and it will probably be just as significant as a lithium battery or fuel cell power.

[@rodbutler8069]

Having H2O as a residue of combustion is a plus.

[@chrishaase]

I'll take pure electric over an hydrogen vehicle any day of the week. Storing hydrogen in large quantities is difficult and dangerous. You are required to store it at very, very high pressures. It takes a lot of entry to compress it and fill the tanks. Hydrogen isn't easily contained either. If it leaks, it is a LOT more volatile than gasoline. You are sitting on a bomb.

[@TheCartoons4you]

@@chrishaase "you are sitting on a bomb" Not necessarily, as one could use a system that worked on demand, in this way you would never have enough stored in the lines to do anything serious. H20 as the residue, and oxygen as the release, does not sound too bad.

[@chrishaase]

@@TheCartoons4you It's not about the volume as much as getting everything sealed. If one fitting starts leaking, you have an issue. The flow has to be continuous while the engine is running. Hydrogen storage needs to be done at insane pressure. You need 3500 cubic feet of hydrogen to get the same BTU as 10 gallons of gasoline. You don't have 3500cubic feet of space in car so you need to store that at very, very high pressure to make it fit in a reasonable amount of space. One leak will cause a LOT of hydrogen to come out.

[@commscan314]

Jesus Christ, the Hindenburg Disaster has fucked people's reactions to hydrogen storage, especially as fuel.

While a hydrogen fuel cell is certainly more efficient than a hydrogen combustion engine it still has abysmally low efficiency "well-to-wheel" when you put it besides a pure battery electric vehicle. From hydrolysis to compression losses to transport to making power again a hydrogen fuel cell engine is about as power efficient as a combustion engine (about 1/3 the efficiency of a BEV). This isn't even open to being mitigated by technical advances as the energy losses in the conversion are pure physics. To put this another way: in order to supply the energy to an automotive sector run on hydrogen fuel cells instead of batteries you'd need - three times as many new powerplants (which need to be paid for by the cost of the sold hydrogen) - factories that can produce and compress hydrogen in quantity (which need to be paid for by the cost of the sold hydrogen...including profit for the owner of said factory) - a way to distribute said hydrogen (as opposed to power for BEVs for which a distribution network is already in place) - vastly more expensive fueling stations (about 5 million $ a pop...a price for which you could build around 500+ BEV charge points..and which, again, need to be paid for by the cost of the sold hydrogen..including the profit for the fueling station owner) ...all of which combined would make commercially viable hydrogen hugely expensive. Certainly there's no way this could be even close to competitive in terms of dollars/mile with just taking the power from step 1 and plugging it directly into a battery.

[@techmage89]

Hydrogen can also be made via gas reforming where natural gas is abundant. I agree that compact storage remains a major problem, but hydrogen has excellent energy density compared to batteries, so it could be useful for applications where weight is a major concern (e.g. aviation).

What do you think will happen when everyone gets home, plugs in their cars, and goes to make dinner/watch TV/run the microwave, etc? The only way to make that work is with grid energy storage(GES) systems. Currently the most efficient GES is batteries so that means the full conversion chain for an EV will look something like this: HVAC> LVDC>chemical>LVDC>HVAC>LVAC>LVDC>chemical>motor. Once you consider all the conversions, batteries are actually less efficient. For reference, hydrogen is only HVAC>hydrogen>motor. -Hydrogen is much easier to produce than batteries. Exactly where do you think batteries come from? -There is no disruption system setup that can handle EV. Every car uses power about 100 times as much power as an oven; do you really think the current power grid would hold up if everyone bought 100 extra ovens and turned them on at roughly the same time? -You can't compare a station to what is equivalent to a pump that only one(maybe two) person can use. Only the underground hydrogen tank cost a lot, but a station only needs one. Even a small gas station has 8 pumps which can service dozens of people over a day. 1 hydrogen station per 500 people doesn't seem unreasonable at all. In fact, that is probably more than we have gas stations today. I get the feeling you don't know much about the engineering/science involved. Currently, there is no physical way for BEV to replace oil based fuels. We simply don't have enough raw materials to make batteries and we are on track to run out of the metals used in Li+ batteries way before we run out of oil.

@@coldblue32E Lol no. Petrol cars will still exist and be used wayyyy longer than two decades. Diesel cars may go away but petrol cars aren't. Maybe not in places like the US but here in Europe they are not going anywhere anytime soon.

[@taz874]

@@isr2879 several countries like the UK, France, Norway, Denmark and others have announced plans to ban sales of new petrol and diesel cars within the next 20 years. Alot of major cities also plan to ban petrol or diesel cars. So yh I'd say petrol cars have a limited future i mean there will still be hybrids which do technically use a petrol engine along with an electric motor but traditional full petrol cars will be gone

Informative, but not that helpful for those of us who ride motorcycles. Could you do another video contrasting the pros and cons of these two solutions for motorcycles. There is a great variety of ICE motorcycle designs to suit different types of usage, but for example my Yamaha MT-07 weighs about 400lbs and produces about 74hp and 50 foot lbs of torque. My daughter's Yamaha YZF-R3 weighs 365lbs and produces about 42hp and a little over 20 foot lbs of torque. Currently, there are a variety of ICE motorcycles available weighing in the 430 to 450lb range producing 200hp or more. Given that motorcycles are very small, the greatest challenges for any new power technology will be to match current ICE power and range without increasing size or weight or diminishing range.

You seem to be assuming a 95% or greater efficiency for the several energy conversions in the FC vehicle.

Hello, not sure if you will see this message, would you go over Nikola hydrogen fuel cell trucks and the Tesla semi truck. Would you explain which is more viable or if both have benefits in their own respects? Thanks

You will never get a response from Jason.

[@restrepojorgea]

Sir, what is the total weight comparison between both concepts ? Assumi g cars with similar specs.

[@ambergris5705]

Yeah, but I have a question : could we convert old cars to hydrogen? I would love to be able to go in town centers in two decades with a 427 Cobra, but not an electric/fuel cell one.

[@Razor-gx2dq]

I think it is possible because the engine still operates on the same principle just a different fuel source. I am not sure what modifications would need to be made in order to get it to work.

[@mgburrito7829]

@@Razor-gx2dq it would probably need the timing to be adjusted because hydrogen burns a lot more violently than gas

[@peterdoe2617]

A swedish engineer ran his Volvo on hydrogen, back in the early 8ies. Sadly, I don't have that magazine present, 40yrs later. But it IS possible!

[@omfgwtfbbq90]

As much as I like ICE and its sound etc, I hate to admit that I think that electrical drives are way more efficient and faster and quieter. The instant torque is so good. In the ideal future most of us will have some kind of ICE hobby/weekend car or motorcycle but a hydrogen fuel cell or electric car as a daily. No way I will never want to hear sound of a nice high revving motorcycle ICE ever again.

[@rayoflight62]

In a hypothetical hydrogen / Fuel Cell automobile, it would be possible to use some of the gaseous hydrogen to heat the inside of the car (and the fuel cell and brake recovery battery) when you have freezing weather like that - 20 °C, where normal electric cars have no source of waste heat to keep passengers healthy warm?

Is there a more efficient engine that could use hydrogen as a fuel source? Maybe we're asking the wrong questions?

[@topsecret1837]

Nybbl er Hydrogen is extremely high on the octane list so diesel wouldn’t be a good option because diesels work on an entirely different rating. Plus hydrogen burns extremely hot so it’s not easy to design an engine that can use it.

[@accelerator5524]

@@topsecret1837 you could coat the parts which are exposed to the heat with a plasmacoat. it can withstand temperatures of over 7000 C

[@michaelossipoff2433]

The Stirling is the most efficient heat-engine. More efficient than Otto or Diesel. With the constant, complete, clean burning of an External-Combustion engine. NASA's MOD2 Stirling-powered Chevy Celebrity beat the original Otto Celebrity in 0-60.

“They come back because they’re very kind” I laughed so hard 😂

[@RoyR3785]

Is power to weight ratio accounted on this comparison somewhere I missed? The less component and weight of combustion type could compensate to the efficiency vs fuel cell type that is much heavier.
