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.

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.

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.

@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.

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.

I mean, there’s even more problems with storage: Hydrogen is such a small molecule it diffuses through _anything,_ so while you’re just sitting there, your car is leaking fuel. Also, filling it up is a huge issue, because of multiple reasons: • it‘s hard to get such a high pressure connection system both reliable, safe and easy enough for regular people to use (the part that is the nozzle on the fuel hose today-in a hydrogen car, it has to be a leak proof interconnect that can hold the 10k PSI, have high pressure valves on both ends of the connection and can still be easily connected/disconnected hundreds of thousands of times), • it‘s hard to store for the station (needs huge tanks and they are, again, leaky), • and on top of it all, it‘s ridiculously easy to ignite compared to gas or diesel, so if there IS a leak somewhere, the smallest spark can make your station into a Hindenburg reenactment.

While H2 Permeation is an issue, it is very time dependent; unless you're trying to store a fixed volume of gas for a long time, the amount lost to permeation would be miniscule when compared to the volume which is used. E10 gasoline suffers from similar long-term storage issues due to water absorption, so the permeation issue is less of a concern than you might think. The bigger issue is closely related, which is maintaining a leak-tight H2 management system (since H2 is far more prone to leaks in fittings and pumps than other compressed gasses). As for your other issues with the gas handling challenges, there is actually good news: most of those issues have already been addressed by previous compressed gas handling solutions. Compressed natural gas in particular has set most of the engineering standards for dealing with safe and repeatable solutions for the transfer and storage of a compressed flammable gas, so most of the engineering best practices and standard operating procedures for users are already mature.

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.

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.

I think reformed methanol is probably the best way to solve the storage issue for hydrogen vehicles. Methanol has more hydrogen per unit volume than liquid hydrogen does, and you get the choice of autothermal reforming, or steam reforming using water (which, incidentally, both h2 fuel cells and ICEs produce). For combustion engines, you can also play games with the mixture, since methanol is itself a perfectly good fuel. I don't think the way hydrogen is currently produced is a particularly relevant argument, since green hydrogen is already cheaper under certain circumstances than even grey. And the key point in the article you quoted is "usable electricity". The trick is that to run grids on stochastic generation, much of the electricity we generate won't be usable, because the robustness of the system is determined at the extremes. A grid that functions on the 5th percentile day where you just aren't generating anything will, by definition, produce massive excess on the average day.

The working class that could afford a V8 could afford expensive brands. Basically, they weren't that much of a working class anymore. Yes, that car you want will be expensive.

There is a simple solution for the m54 engines that burn oil, "fixed" 4 engines with the same method. At first you need to understand that they run on way to much oil temp. So do 6x an oil change every 2000km with a good 5w40 like the shell helix ultra, got good cleaning capabilities. In those 2000km drive then engine till it on temp and drive it harder, use more rpm and full throttle (that's what they like anyways) of you've done that 6x make an oil change with 5w50 or stay with 5w40 if you're more the person that drives short distances. This cleans the piston rings, also like I said they like to be driven with a lot of full throttle.. m52s shouldn't have that Problem, of they do, just drive them harder and always do short 15 tkm oil interval on all engines.

Thank you for your video and your quick comparison. However, why don't you talk about costs comparing a fuel cell and a H2ICE?? It is further cheaper to adapt an ICE to work with H2 than using fuel cells currently. There are a lot of scientific papers researching on H2ICE and it is not difficult. My PhD thesis is based on comparing H2, CH4 and coke oven gas in a port-fuel SI engine, showing good efficiency and low emissions. It's true that there's still much work to do, but with your general comments, you just do a simplified comparison, taking down the work of many people during years. And you only take as a reference the job of a company on a single car, instead of referencing scientific papers. On the other hand, do you think that taking a single quote of a report is enough to say that H2 has no role in the future energy system? Try to store electricity during months with huge batteries at the same price compared to H2 using salt caverns or think the price of the reinforcement of the electrical grid in the future as the electrical demand increases, compared to using H2 pipelines which is way cheaper, as seen in many papers. Many scientists and countries are investing in H2 for many reasons, not for just a report or a single quote. I just ask to avoid giving quick general conclusions which influence people, instead of providing information to encourage people to inform and learn more. Technology can develop and improve very quickly, as seen during the last century. Sorry for the length of my opinion and I don't want to offend anyone! Thank you again for your videos!
