    May I suggest we take a pause and wonder why Japan invests in Hydrogen considering Japanese companies lead in battery technology. Seems like Germany is also investing in Hydrogen. I worry that we become dependent on rare materials like Lithium. Mined in China? Perhaps there are other choices but when? I am just an Engineer who respects Japanese and German basic research. Elon Musk may be a genius. Is he considering what is best for USA long term? Is a Giga factory in China best for USA?

    why not use hydrogen directly as "fuel" in a combustion engine?
    it has a WAY denser powerdencity (octane) than gasoline ...
    why dos it have to be converted to electricity???

    there are a lot of inaccuracies in this video, a lots of info about batteries not included, H2 production and storage, electricity grids are not built to handle power requirements needed for majority drivers to go on battery cars, cost of overhauling the entire US electricity grid?

    Plus there are experimental ways and traditional methods of mass producing H2 without pollution, e.g. Hydro-thermal power (Iceland can supply all Europe's needs for H2) and scientists are genetically engineering algae to use photosynthesis and mass produce H2 very cheaply from Sea water. Add to that new storage methods using nano tech which don't need to pressurise or cool H2 in order to store large amounts.

    Basic fact is H2 is far, far more powerful per Kg than Batteries, incidentally 2.5X more powerful per Kg than Petrol, which makes it a far better source of energy provided sufficient investment is given to solve some engineering problems, and Greedy SOBs dont block the technology from maturing.

    (1) Hydrogen is still more efficient than gasoline.
    (2) Water is abundant. Every other fuel is going to be used up.The burning of hydrogen produces only water. Thus reducing pollution. The water produced just becomes a part of the water cycle.
    (3) Hydrogen could be used to make electricity, which could then be used to run electric vehicles.
    (4) Renewable sources of energy, like Hydroelectricity, Geothermal energy, Tide energy, and wind power could be used to make the Hydrogen by electrolysis of water.
    (4) Cars with Internal Combustion Engines can be easily adjusted to work with hydrogen.
    Sooner or later we will have to turn to hydrogen.

      To 1. please elaborate
      To 2. Sure but the water does not give up the Hydrogen without a fight and it takes more energy to convince the water to give up the Hydrogen then you will ever get from the Hydrogen that's being produced.
      To 3. and the Hydrogen was produced from what? Natural Gas? Oil? Coal? Renewable (your point 4)? IMO far more efficient to cut out the middle process of making the Hydrogen and use the sources directly to make the electricity and charge the EV directly
      To 4. Using Hydrogen for smoothing out peaks and lows of renewable Electricity production has possibilities but using renewable for primary Hydrogen production, nope just not efficient.
      To 4 below the other 4 ( guess you made a Typo ). I say conditionally yes however the big question is how are you going to handle the onboard Hydrogen storage issues?

    This seems like a huge promotion for Tesla, I understand Elon is very charismatic and he has many fan boys, but just manufacturing the car already bloody pollutes the atmosphere more than anything. How can one say these vehicles are pollution free?
    Ok then more to the point, lithium is rare and terrible after a few charge cycles. And I would love to know how it’s going to be manufactured and refueled when we run out of fossil fuels.
    Nuclear power? Why can’t there be a centralised hydrogen and water distillation cum power plant near the sea and distribution networks?

    500km range? Wow, that's barely usable in Europe, how anyone expect it to be usable in US? And when it comes to Tesla the charging time just kills the idea for me.
    1000km with under 10min refuellings on the road is my minimum while living in central Europe.

      @ollierkul Well, I'm from Poland, my college is over 400km from my home, I have to make the trip multiple times a year, it would barely last for me. And my college is on central Poland, if I'd manage to get into more prestigious one, then I literally wouldn't be able to use that car to travel.
      Even traveling around region I wouldn't be surprised to run low on energy with Tesla. The closest big city fromy home is around 150km, that's 300km without counting going around the city between different interest points, visiting friends and buying at the shops.
      Not to mention the cost of a car means that it WILL affect your future life decisions, such as where you will live ( better not move somewhere where there are power outtakes and it's above 50km from a somewhat big city, you may get strandled without a means of transport ), what job you'll take (if it requires traveling a lot and doesn't provide own car, you can't take it, even if it provides own car, such as a TiR driver it may make your life miserable if you'll have to exchange a guy due to some reasons and he's over 250km from your home) and many others.
      I just don't see a car that has such a low range with such a high charging time being usefull to anyone who wouldn't be 100% fine with not owning a car at all and just using public transport.

    • ollierkul
      ollierkul Day ago

      A lot of us live in cities or close to cities and dont do long journeys. The longest journeys I do is typically to my cottage, about 150km, maybe a bit more. And that includes quite a lot of going up and down and being ik a colder climate that Norway has, so you can factor in some efficieny loss there. In a model 3 that journey would be no problem. And then it comes with the benefit of being able to charge it at home overnight. So realistically I very rarely would have to fill up at a station, unlike a gas car. As with most things there are cons and pros, and for many of us EV's pros outway the cons... especially the cost at the moment.

    • Milan Swoboda
      Milan Swoboda Day ago

      @I don't give a Fork , re-read your post and you wrote don't need to make it on demand, sorry about that. With this I will rephrase my questions thereafter a bit. How much electrical energy ( renewable or not ) is approx. required to produce a kg of H2 which gives a Toyota Mirai FCEV approx. 100km driving distance and is this competitive against charging a BEV overnight with the same electrical energy or in case of use of non renewable utility electricity competitive with the petrol prices for current ICE vehicles?

    • I don't give a Fork

      @Milan Swoboda Well practically Free!! I said "some people" will be able to make their own Hydrogen...Not everyone, just people with a little land. Obviously not everyone is in that position. However many people may be able to access Hydrogen produced by local community systems. Tax on gasoline In the UK is very high, so Hydrogen from mains electricity can be produced cheaper than gasoline. I dont understand your comment about "demand production"? I said " Your system could make it for you while you are at work or while you sleep and store it.. 24/7" ..Which is the opposite of on demand ie producing it slowly

    • Milan Swoboda
      Milan Swoboda Day ago

      @I don't give a Fork , renewable is not free because you have to first invest in it plus you have to invest into the Hydrogen production equipment, additional there are running cost like maintenance of the whole system which is not free
      Oh yes on demand production - please elaborate on how you are going to achieve that and would appreciate some numbers like H2 produced ( kg or Liters ) with how much energy needed to produce it, where you're going to get that energy from and how much excess usable energy is going to be produced. Just some rough numbers I'm not too picky.

    • I don't give a Fork

  • Barry Burgert Potgieter

    How about mixing Hydrogen with your Petrol instead of normal Air.? Hydrogen is explosive and help Petrol to give you higher explosion leading to adjusting Petrol input to a lower level thus using less Petrol. Cheap to manufacture Hydrogen from water. Google Hydrogen making here on TheXvid. Very easy and cheap.!

    • Milan Swoboda
      Milan Swoboda 13 hours ago

      @Barry Burgert Potgieter Oh and I forgot here examples of what "real" Hydrogen generation equipment is like just to give yo a better idea.
      There you see equipment with a H2 production range from 0.06 kg/day up to 2.5 kg a day with a power consumption range from about 64.5 kWh/kg H2 to 90 kWh/kg H2

    • Milan Swoboda
      Milan Swoboda 14 hours ago

      @Barry Burgert Potgieter LOL yeah it does make a nice bang but to get useable energy out of it you need a very large volume of H2. 1kg of H2 is the specific energy equivalent of 3.8 liters Gasoline. That means it is lighter than the Gasoline which would weigh about 2.85kg which is nice, however 1kg of uncompressed H2 has a volume of about 12 cubic meters which would be a spherical balloon with a diameter of 2.8 meters filled with only Hydrogen. The electricity needed to make that amount of Hydrogen via Electrolysis would be from about 50 kWh ( large scale ) to over 150 kWh ( small scale ).
      Note that kg of H2 would give a Toyota Mirai FCV a driving range of about 100km ( careful driving ) and current BEVs consume about 15 to 25 kWh of electricity for the same distance.

      Hydrocarbon fuels already contain plenty of Hydrogen hence the name Hydro(gen)carbon and adding a little H2 to the inlet Air is not going to help much if anything. Those like you that say that Hydrogen is cheap to manufacture from water do not understand how much Hydrogen actually needs to be produced to replace a given quantity of Petrol and how much energy is really needed to produce that quantity. Reality would likely send you shivers down the spine ;)

    A couple of things this video does not mention:
    1: both options are hugely cheaper than gasoline/petrol in day to day running costs. But, how much to replace worn out batteries/fuel cells?
    2: lithium based batteries are NOT the answer. Lithium is already a relatively rare element not including how nasty it is to the environment to purify and recycle.
    3: where is the comparison to burning Hydrogen in combustion engines like gasoline/petrol?
    Money Cost should NOT be the main reason. LONG TERM sustainable with the least damage to environment should be primary reason.

    Finally, to the people saying we should stick with gasoline.... sooner than you think there will be no option. The days of pumping pure crude oil from the ground are almost over. That is why oil companies are working with fracking mud oil, tar pits and oil sands... in other words, the low quality dregs.

  • Saucy Secretz

    Currently, a lot of our power in the United States is generated by natural gas and coal (because of this its more efficient to heat a house with gas for instance). Solar sounds nice but generates so little electricity and doesn't work well in certain areas let alone is affected by weather and lack of sunlight in general. Lithium cells are heavy, have limited lifespans, pollute and don't store much electricity compared to their weight and size. The cost of hydrogen will go down when more then 20 people are driving the vehicles. Not to mention that during winter the electric cars become very in efficient suffering from the constant to need to warm the batteries. Hydrogen also seems like the natural choice to preserve the industry and jobs currently a result of fossil fuel (fuel stations, production, and transportation). I think we should continue to pursue every avenue available to us, let the technologies advance and give both a fair shake before coming to conclusions.

    • Milan Swoboda
      Milan Swoboda Day ago

      @Saucy Secretz On this planet Lithium is more abundant than Lead which is used in pretty much in every ICE vehicle out there plus radiation shielding, back-up power systems. ...etc. so no I do not see it problematic. Yes high efficiency motors used worldwide ( not limited to EV use ) use Neodymium which has the "rare Earth" designation but also there I do not see a problem on the long run since it is not the only option for Electric motors out there .

  • GhostDogg o
    GhostDogg o 2 days ago

    Well the cost of a battery is too high, and the energy density per kg to low, also factor in you must have your battery packs serviced every few years due to failing cells. ie battery cells degrade over time holding less energy as they age and i'm fairly certain that servicecost will outweight the cheaper charging cost, plus factor in that more people driving those battery cars drive up the electricity cost and now everyone will pay high energy bills,YAY! besides unless we embrace nuclear power and stop being so fearful, you can forget about it all with the unreliable energy-yield from solar/wind.

    That being said hydrogen also requires energy to be produced,however it's energydensity per kg is much higher, also hydrogen gas is highly flammable so proper safety mechanisms such as quick drain valves are a must for those pressurized containers if you have them in vehicles.but the tanks don't need replacement or revision periodically but they may need inspection and certification every decade or so akin to the high pressure diving equipment. For larger countries as the USA localized production is better than centralized production facilities, yes prices will rely on supply/demand and fluctuate. Smaller countries might be better of with centralized production to cut costs.

    Personally from what i know i find the hydrogen fuelcell a better option overall.

I looked for a ¨rare earth metals" and could not find any reliable reference to that but could find solid references to a REE ( Rare Earth Elements ) Category which apparently is a historical Category name that does not really indicate that the elements in that category are truly rare. I than took the elements in that category ( under the assumption that it is really the REE category you are referring to ) and compared them with materials that are used in EV batteries and came out empty.

    Electric cars are not free from causing 'pollution' including CO2 emissions, they just pollute at the location of material production, manufacture and power generation rather than where they drive. The production of electricity from non-polluting means is minuscule. And electric cars use more energy than fossil fuel powered cars both in operation and whole life.

    He doesn't add in the extra energy needed to make the battery. A battery pack adds 50% more energy to the manufacture of the vehicle. Moreover current batteries last only 250,000 miles and then need replacement. He doesn't mention NH3 as a hydrogen carrier which eliminates the need for hydrogen compression. All in all hydrogen is still competitive with battery electric.

      you fool, he is explaining production and transportation of the 2 types of fuels, not manufacturing costs, also if you are including battery production costs you need to include H2 storage and refinery costs which certainly does not help H2s standpoint.

    There are electrolysis systems that produce 1 kg of hydrogen pressurized to the working pressure needed for vehicle use for only 55 kwh of electricity. This allows for the use of renewable electricity, off peak should be very cheap. Also, the battery vehicle is heavier, and will consume more kwh per mile.

    • Milan Swoboda
      Milan Swoboda 4 days ago

      Ok so 55 kWh for a kg of compressed H2 and a Toyota Mirai drives about 100 km with that kilo.
      BEVs nowadays require about 15 to 20 kWh per 100 km which means that you could charge and drive 2-3+ BEVs for 100km with the same electric energy that a single FCEV requires for 100 km.
      As for weight, I recommend that you compare the curb weight of a Toyota Mirai and a Tesla M3 long distance, both have similar driving range then come back and tell me which is heavier.

    Would it make sense for cars to be a plug-in hybrid, but with hydrogen instead of gasoline. We have plug-in hybrids today. Currently, plug-in hybrids allow people to do most of their commutes on the battery, which they can charge from their home. When the battery isn't able to power the vehicle, the internal combustion engine kicks in. Unlike most hybrids, plug-in hybrids let you charge the motor's battery via an electrical cord from home. Many people who drive plug-in hybrids find they don't fill up with gasoline for months because they rarely drive long distances. Most of their driving is done with the electric motor.

    Hydrogen is expensive, but if you rarely burn it, then it doesn't matter. The battery is the primary source of power, and the hydrogen fuel-cell is the backup. Wouldn't that solve the range-anxiety issue and also be a good way to offset the cost?

      Heli Mark that’s just not true (as most scientists agree). Oil is renewable it just takes millions of years for it to renew and we have used lots it already. If we assume that all the electricity that powers an electric car is from solar panels or wind turbines then sits 100% green. This is almost always not the case but as the national grid gets greener as coal and fossil fuels are removed we get closer to it being 100% renewable. Petrol/desil is one of the worst ways to power a car, but it’s the easiest so it’s the one humanity chose. Also oil is fossil remains. That’s literally what it is, it’s old rotten animals that have been buried and put under such high pressure and temperature that some funky stuff happens and they become hydrocarbon

      @maisto That would require charging stations to stockpile a variety of batteries. In addition, batteries discharge over time and the quality and wear of the replacement battery may be different. Finally, the manufacturer would have to design the vehicle for a quick-release battery, which would be more costly and encourage theft. It would be great in the future when standardization of batteries and anti-theft devices were prevalent.

    We can efficiently create Hydrogen and remove landfills while creating zero pollution. It's called the Kim Reformer and it converts all waste; from household to industrial and medical waste, to pure Hydrogen. Then you can either convert that into electricity utilizing gas turbine engines; create fuel cells or sell Hydrogen directly.
    We can produce Hydrogen efficiently all over the US as filling stations and power plants. Eliminate landfills; except for nuclear of course. Working with Mexico, trying to work with Canada and the US right now.
    Tell your representatives to use the Kim Reformer and contact Seth. There is a good chance I've already contacted them. If not, send me their contact info and I will.
    And the pricing is the same or lower than Hydropower 0.03kW. - Last thing, we actually give the power plant to municipality after 20-30yrs so it's an asset.

We are working on changing that law so we can build out the facility. Just because you are unable to comprehend science, politics, intricacies of global agreements, etc... doesn't mean the rest of us have the same hindrances.

      You won't believe this either, but we have technology to take waste plastic and turn into composite railroad ties that last 100 years. One railroad tie saves 1/4 of a tree and its *carbon* *negative*. After the 100 years is up, you recycle into a new RR tie. Need $2m and Brown Financial will give us another $8m to draw down on. Unless you have $10m to invest. -- I'll make sure to send you an invite to the green tech crowdfunding site so you can donate $100 and make a difference by financing your own RR tie.

    The elephant in the room is all of your data presumes the electricity comes from renewable sources. Most of the electricity we use today does not come from renewable sources. It uses natural gas, coal or nuclear sources to produce electricity. Please add that into your equations for cost of kilowatt hour and CO2 output. This would produce a more accurate measure of cost. Renewable energy sources are not viable for industrial scale use at this time and should not even be a factor in this discussion.

    I agree that right now scarcity of market production is driving costs of hydrogen cell technology. I have seen modern vehicles using the hydrogen to drive a turbine instead of relying on pnm. It looks like hydrogen will be the same cost or similar to petrol with the same or better range depending on tank size. I have long commutes and I live in a country that requires long distance driving.. Hydrogen sounds great.
    Is it possible to eventually get the processing plant down to a size that we can get one per community, ideally one per house. Seems doable.
    People seem to forget that petrol stations were once a novel new technology with only a few cities having them.
    Despite petrol being a very mature technology petrol costs are going up!
    One advantage of communities having their own hydrogen station (depending on cost) hopefully would be an independence from a certain amount of government control and price fixing, and also a reduction in shipping costs, possibly the need to invade otber countries for oil.
    There are people already making hydrogen from waste. Seems like a good idea if it is not prohibitive energy wise.
    I like the idea. Time will tell. Best fuel source in the world doesn't solve the problem that there are just too many people.

    My main question is, what about using hydrogen to power an internal combustion engine? A hydrogen powered engine would be more efficient than a comparable hydrocarbon engine when it comes to how much you should be able to carry vs. oil, as H has 3x the heat per lb
    But with an engine that's really not what you're looking for. So, what about using hydrogen to generate heat instead of powering vehicles? That would reduce the amount of oil we're using in places where H would, "make more sense", I guess? Again, we're getting into production costs and everything, but wouldn't it be worth looking into? I would really like your thoughts.

      Because H2 has a low energy density by volume. The Mirai dual cylindrical tanks can hold a combined 5kg of H2 but have a volume capacity of over 120 liters and just the tanks weigh in at 87.5kg, Cylindrical tanks are necessary due to the high pressure the H2 is at but that makes it difficult to place them in the vehicle without intruding into the passenger space while still being safe and that will limit the amount that can be carried plus you have the conversion efficiency of the fuel cell stack which doesn't help the matter.

    You should also mention that the batteries themselves change. We have many new battery types just around the corner, some with much higher capacity and current. So it may take only a few minutes to charge at a station using a high amp high voltage supply. But yea at home charging is slow. But then again do you see anyone having a gas station in their home? no. I fully believe that electric cars will overtake their old gas powered counterparts in both range and charging time. And the natural(yes NATURAL) transition of economies will be in full swing. So to those protesting the oil industry and pipelines; newer technology is what will push them out of the picture, not you signs and chants. And it is better for the economies as well. Gives time and revenue for formally oil based economies to transition to the newer stuff. For example Canada moving on the Lithium and other metals. The middle east moving toward tourism and businesses hubs(like Dubai). It is easier to transition from one economy to another then it is to shut down an entire economy hoping to rebuild it from scratch. You can't build with nothing.

    Why not use electrolysis and hydrogen production using the energy from the alternator. Hybrid technology should work with each other.

    • Milan Swoboda
      Milan Swoboda 5 days ago

      @Thaopao Yang Yes the alternator charges the battery if needed while the engine is running, however the alternator will take energy from the running engine to generate the electricity to charge the battery . More electrical load on the alternator also means that it will take more energy from the running engine plus due to efficiency losses it will take more energy from the engine than the electricity it will produce.
      The electrolysis is not very efficient so you will require far more electrical energy to produce the H2 or HHO than you will get from the Hydrogen you've produced. After that you run an combustion engine with the gas you've produced but the engine is also inefficient to convert the chemical energy from the Hydrogen to kinetic energy to move the car and run the alternator.
      so it's a death spiral of inefficiencies thus will not work

    Great job of showing why hydrogen fuel cell systems are not the future. Anyone who claims otherwise does not understand the importance of efficiency when it comes to using renewable energy sources for fuel. Bottom line: It would be a colossal waste of resources to try to make fuel cells work especially with renewable fuel tech as the primary hydrogen process fuel source. Big oil is heavily subsidizing all facets of fuel cell because it's the only way gasoline/petrol remains viable with battery powered cars. Sure gas turbines can produce electricity but the Sun and wind will soon eventually make that option obsolete as the renewable tech matures. Big oil knows this hence why it wants fuel cell cars to take off. It's a dead end.

    What bunk this video truly is. All one must do is replace their regular spark plugs with specially designed spark plugs that convert every cylinder into a Hydrogen generator IN REAL TIME. In other words the special spark plug uses the 10,000 volts being delivered to it by a coil pack to separate Hydrogen and Oxygen from the water being delivered to the motor from the fuel tank by electric pumps AND detonates it in the same 1/100th of a second with NO electrolyte. The only conversion your engine needs to use this system is to adjust its timing to top dead center of zero as Hydrogen will explode 200 times faster than gasoline or diesel. This system has already been tested and is 100% successful and reliable. Why then fool around with fuel cells which are only 82% efficient when special spark plugs are 99% efficient? The maker of this video is either unaware of this or he is pushing his own agendas for the slim market for a company who is clueless. Either way they are behind in the latest technology.
