  1. LOL well that was counter climatic if it's not more efficient as a whole then it makes no sense to adopt it given the amount of conversions to infrastructure and processes that would be needed to adopt it. But some sort of holistic statistical comparison against another popular vehicle would be nice.

  2. Solar or wind power technology to source the energy needed for water cracking hydrolisis will make it more cost effective…I still prefer HHO augmented fuels, such as diesel or gasoline engines utilizing Hydrogen On Demand, which also gives a clean burn, zero emissions, and is much safer and more cost effective…check out HHO generation tech.

  3. Until a car is made with an alternative fuel source aside oil for $20k, these things will never catch on. If you can't change the masses what's the point in trying to go safer, cleaner methods if only the rich can afford them and even then they might choose a more stylish well known luxury car instead of these dumb looking toy cars.

  4. Right! But Thank You Toyota for starting this campaign. If all the world ships planes and automobiles ran on Hydrogen then it would be cheap and we would have less pollution….keep up good work and thank you again Toyota!

  5. This is an excellent vehicle I believe. A vehicle powered by the universes most abundant element sounds like a no brainier idea. I doubt that I would feel bad for the multibillion dollar industries who have caused so much destruction and war for black gold.

  6. Deliver hydrogen to homes and businesses just as LP and Natural gas are delivered today.  This will potentially help bring down the cost of hydrogen in addition to increasing demand.  And delivering H2 this way, it can still be taxed too.

  7. At present, 95 percent of America's hydrogen is produced from natural gas. Through a process called steam methane reformation, high temperature and pressure break the hydrocarbon into hydrogen and carbon oxides — including carbon dioxide, which is released into the atmosphere as a greenhouse gas. Over the next 10 or 20 years, fossil fuels most likely will continue to be the main feedstock for the hydrogen economy. And there's the rub: Using dirty energy to make clean energy doesn't solve the pollution problem-it just moves it around. "As a CO2 reducer, hydrogen stinks," Joseph Romm, executive director of the Center for Energy & Climate Solutions, said. I would only support hydrogen fueled cars if the hydrogen was created by electrolysis, and that electrolysis process was driven by wind and/or solar sources. Realistically this scenario would be at least 10 to 20 years away based on most available sources today, especially considering the political forces we are constantly battling with that push to subsidize and advocate fossil fuels and fight against the alternative energy industry. A much better and simpler solution is to fuel electric cars from roof-top solar panels. Even using electricity generated from a solar plant or wind farm would be far simpler and would be better in terms of CO2 emissions. As an example, I already have solar panels installed on my roof and drive a Nissan Leaf daily to and from work and elsewhere. The solar panels paid for themselves in seven years, and I haven't seen a gas (or hydrogen fuel) station in two years since I bought my Leaf. It was not terribly expensive, relatively speaking for most homeowners, and it was also fairly easy to accomplish.

  8. Can someone tell me if this idea is dumb. What if a vehicle had two batteries and lets say it were feasible to have two batteries in an electric vehicle, and I realize this ad is for a hydrogen vehicle, but what if at first, the vehicle runs on one battery then when that one is depleted is changes over to the second battery. While the vehicle is running on the second battery, it's charging the first battery. Would that work? And maybe some sort of solar charging as well to boost the charge rate?

  9. use hydrogen to run an electric motor? doesn't that beat around the Bush..why not just use battery powered electric motor? geez hydrogen takes a lot of energy to make, store, and transport.

  10. Tidy video but that comment at the end is a pile of shit, not all hydrogen is made from a dirty source or transported using filth like diesel powered lorries, those are the refinements that needs to be sorted on a mass level, and it could be done easily, people are just way too fuckin' lazy to do anything about it because they'd prefer to just go down the easier route and drag that out as long as they can, use whatever diesel shit mobile they already got and instead of changing for the better, they'd prefer to chuck disgusting toxic filth into the air.

    Thing is though, most adults have something in common and that's they want a good future for their kids, well it's their kids that are gonna have to breathe all the shit their "parents" are dumping into the atmosphere, even the greedy rich heads of dirty energy and oil companies have kids so they really need to have a think about that, knob heads. The technology's there, it can be done, just bloody do it.

  11. Hydrogen: good. Looks: bad. Price/Quality ratio: BAD… Toyota, why do you do this?! The concept is awesome, if only it looked better people would buy it more, and especially for €60.000

  12. fueling time and range are the key points game changers. if you would have a race between this car and an all electric the Toyota would win hands down. why not have one New York to LA. God's speed Toyota.

  13. hydrogen cars can really ECONOMISE MORE FUEL COST THAN ELECTRIC CARS IF WE MODIFY OUR CURRENT HYDROGEN DISTRIBUTION APPROACH ! 
     The biggest cause of hydrogen cost is that WE TRANSPORT HYDROGEN BY TRUCKS, IT IS EXPENSIVE. Just try to avoid to transport hydrogen by trucks, then hydrogen will be very cheap. It means that NEED TO PRODUCE HYDROGEN ON SITES (WHERE FILLING HYDROGEN), OR TRANSPORT HYDROGEN BY PIPE LINES. 
     So we need to make 1 or 4modifications : 
    1/ Distributed hydrogen production on sites : hydrogen filling stations should be equipped with electrolysers, so hydrogen filling stations can produce hydrogen on sites from electricity outlets, instead of just receiving hydrogen from other places. Thus avoid problem cost of transfer hydrogen by trucks. Besides, nets of electrolysing hydrogen filling stations are ideal markets for intermittent renewable energy.  
    It is new worldwide coming hydrogen distribution approach, so it opens markets of mobile small sized electrolysers. Electrolysers are not so expensive for hydrogen filling stations.
    2/ Use compressed gas hydrogen batteries with mini household  electrolysers/mini mobile electrolysers : small mobility vehicles/mobility machines/mobility robots/mobility drones …, will use hydrogen gas batteries (hydrogen gas battery =hydrogen fuel cell + compressed hydrogen gas ballon 200-300 bar). And each of these mobility machines can be sell with mini home electrolysers, so that owners can produce to fill hydrogen at homes (charge hydrogen batteries at home). Hydrogen ballon 300bar is enough, so that hydrogen battery 300bar(fuel cell +hydrogen ballon 300bar) can guarantee more energy capacity than best lithium batteries, and it guarantees that the size of hydrogen battery 300bar  is not remarkable bigger than lithium battery of equivalent energy capacity. Of course 700bar allows more hydrogen storages, liquid hydrogen allows more hydrogen storage. But for hydrogen batteries, gas hydrogen ballons 300 bar are enough for  balance of performance-capacity-size-energy convertion ratio-ballon material-simplicity. 
    Hydrogen batteries 300bar + mini mobile electrolysers are ideal for two-wheel vehicles/small cars/small robots/drones and for trend of hydrogen mobility devices anywhere (easy to operate  anywhere and easy to charge anywhere with electricity).
    3/ hydrogen batteries for big station energy storage : Independent hydrogen batteries (hydrogen fuel cell + compressed hydrogen ballons > 300bar) + independent electrolyser is best variant. when excess energy, then run independent electrolyser. When need electricity, then run independent  fuel cell. And intrigued working mechanism between independent fuel cell and independent electrolyser. That is all ! No complex automatic control system. 
    4/ hydrogen filling stations need to prefer using hydrogen pipe line than transporting hydrogen by trucks.
    5/ The fundamental science dictates essential truth advantages of hydrogen.
    Science : if a chemical energy storage mechanism is charged as quick as producing hydrogen, then this mechanism PRACTICALLY  CANNOT HAVE ENERGY CONVERTION RATIO BETTER THAN ELECTROLYSIS PROCESS. Besides, it is possible to adjust electrolysis reaction speed to get energy convertion ratio of electrolysis better than any chemical batteries. The best one of all possible chemical batteries in earth conditions is HYDROGEN BATTERY. All revolutions of chemical batteries, lithium batteries, LFP batteries, LTO batteries, graphene batteries .. are for reaching to the features of hydrogen batteries

  14. HYDROGEN AS BATTERIES : New concept : HYDROGEN BATTERIES. Electric vehicles must switch to use hydrogen batteries instead of chemical batteries.

    People often think about hydrogen as fuel, but many forget that hydrogen is not only a fuel, but also very good battery, too.

    1/ The fundamental science dictates essential truth of all chemical batteries : (CAREFULLY RESEARCHED STUDIES)

    if a chemical energy storing mechanism is charged as quickly as producing hydrogen, then this mechanism PRACTICALLY CANNOT HAVE BETTER ENERGY CONVERSION RATIO THAN ELECTROLYSIS PROCESS. Besides, it is possible to setup and adjust electrolysis reaction speed (for example slow down speed) to reach energy conversion ratio of electrolysis better than any chemical batteries. The best one of all possible chemical batteries in AEROBIC earth conditions is HYDROGEN BATTERY. All revolutions of chemical batteries, lithium batteries, LFP batteries, LTO batteries, graphene batteries .. are for reaching to the features of hydrogen batteries.

    2/ New concept : hydrogen battery = (fuel cell + hydrogen storage object).

    The most simple hydrogen battery = 1 fuel cell + 1 compressed hydrogen balloon 300bar, can easily beat best lithium batteries by all features : more capacity, more power, less weight, forever lifespan, no degradation, charging in 5 minutes, same or better energy conversion ratio, but just noremarkable bigger volume sized than lithium batteries.

    3/ So just equip electric vehicles with hydrogen batteries instead of chemical batteries. And equip hydrogen filling stations with mobile electrolysers to produce compressed hydrogen 300+ bar on site from electrical outlets. Electrolysing hydrogen filling stations (hydrogen battery charging stations) can run electrolysers from electrical outlets to produce liquid hydrogen on site, to avoid suddenly leap change requirements for big number of already existing current liquid hydrogen cars in the markets. But liquid hydrogen has low energy conversion ratio. For now and near future, compressed hydrogen (produced on site) is more versatile for various applications.

    (Additionally envisagedly, owners of ANY SMALL COMPRESSED HYDROGEN MOBILITY VEHICLES/ROBOTS/BIG DRONES/MOBILITY DEVICES can buy small mobile household electrolysers to recharge hydrogen batteries at home at night/any times).

    4/ Example and comparison : hydrogen cars vs battery cars, hydrogen batteries vs chemical batteries :

    The old approach sets high H2 cost because : they pay for making H2, then they pay much for converting H2 to liquid H2, then they pay much for transporting liquid H2 by trucks (complex safety trucks, and very small weight of liquid H2 on every trucks), then they pay for keeping cryogen conditions to store liquid H2.

    But in new approach of ‘electrolysing hydrogen filling station” : you use electricity from electrical outlets at electrolysing hydrogen filling stations to run electrolysers to produce compressed hydrogen 300+bar on site. So you pay only for electricity and water of course. No other fees. No complex cryogen equipments.

    Compare : hydrogen batteries vs lithium batteries in the approach of “electrolysing hydrogen filling station” :

    4.1/ Grid transmission loss : hydrogen battery charging and lithium battery charging onsite cause same grid transmission losses.

    Conclusion : Equal.

    4.2/ Energy conversion ratio in charging : (electric energy -> chemical energy)

    Electrolysers in quick mode (very high electrolysis reaction speed) have energy conversion ratio about 70%. Lithium batteries quick charging has energy conversion ratio about 60-70%.

    Electrolysers in slow mode (small electrolysis reaction speed) have energy conversion ratio 90%. Lithium batteries slow charging has energy conversion ratio 90%.

    Conclusion : electrolysers win, because of the ability of flexible modes of scheduling and functioning to reach higher energy conversion ratio.

    4.3/ Energy conversion ratio in performance : (chemical energy -> electric energy)

    Fuel cell has energy conversion ratio about 75+% in mode of intensive power performance (when require delivering much walt/seconds), energy loss in form of heat. Lithium batteries have energy conversion ratio about 70-% in mode of intensive power performance (when require delivering much walt/seconds), energy loss in form of heat.

    Fuel cell has energy conversion ratio about 85+% in mode of nointensive power performance (when require delivering less walt/seconds), energy loss in form of heat. Lithium batteries have energy conversion ratio about 95-% in mode of nointensive power performance (when require delivering less walt/seconds), energy loss in form of heat.

    Conclusion : Equal.

    4.4/ Energy loss in energy packing compressing process :

    Hydrogen battery using compressed H2 300bar cause about 3-5% energy loss for compression. But hydrogen battery weight is very small.

    Lithium battery loses 0 energy in compression. But lithium battery weight IS INHERENTLY HIGH.

    That means you always need to transport noneccessary lithium battery heavy weights on your vehicles every seconds. -> The higher power category, the higher loss with lithium batteries. The longer range, the higher loss with lithium batteries.

    Conclusion : hydrogen batteries win with big advantages

    4.5/ Spatial size :

    Simple hydrogen battery = 1 fuel cell + 1 hydrogen ballon 300+ bar.

    For small capacity category (for example, passenger cars capacity category) : simple hydrogen batteries have little bigger spatial sizes than lithium batteries.

    For nosmall capacity category : simple hydrogen batteries have little smaller spatial sizes than lithium batteries.

    Conclusion : lithium batteries win with nobig advantage.

    4.6/ Lifespan and degradation :

    Hydrogen batteries have practically forever life span, and practically no degradation.

    Lithium batteries have lifespan about 3 years. Some good ones have 5 years. Other modern modified lithium batteries have more lifespan but smaller capacities. But all of them degrade every year.

    Conclusion : hydrogen batteries win.

    4.7/ Influence of environment temperature :

    Hydrogen batteries never fear environment temperatures.

    Lithium batteries fear environment temperature. Even in some seasons you can not or you ineffectively use lithium batteries.

    Conclusion : hydrogen batteries win.

    4.8/ Charging time :

    Hydrogen batteries : load compressed Hydrogen 300+bar or exchange compressed hydrogen canisters 300 bar in 3-5 minutes.

    But you must waste minimal 30 minutes for nofull charging lithium batteries, and often you must waste some money for paying some unnecessary things in fool waiting times too. -> waste time + waste money.

    Conclusion : hydrogen batteries win.

    4.9/ Synchronize with grid supplying schedules :

    Electrolysing hydrogen filling stations can easily pick up flexible schedules to run electrolysers in tandem with grid supplying schedules. So Electrolysing hydrogen filling stations can pick up right hours of day for incentives electrical tarif. Nets of electrolysing hydrogen filling stations ideally use intermittent clean energy/renewable energy.

    But electric charging stations can not pick up times. High power electric charging stations terribly conflict with intermittent schedules of clean energy/renewable energy. The more higher power electric charging station in quick charging mode, the more terribly it conflicts with intermittent energy supply schedules of clean energy/renewable energy.

    Conclusion : hydrogen batteries win.

    FINAL NATURE TRUTH VERDICT : HYDROGEN CARS WIN MANYFOLD AGAINST BATTERY CARS.

    Just need to make right approach : model of distributed hydrogen productions onsite (nets of distributed ELECTROLYSING hydrogen filling stations) + electric cars with hydrogen batteries EXACTLY MAKES HYDROGEN CARS MORE ENERGY SAVING THAN BATTERY CARS, AND IDEALLY COOPERATES WITH INTERMITTENT CLEAN ENERGY/RENEWABLE ENERGY THROUGH ALREADY EXISTING ELECTRICAL GRIDS.

    All new electric vehicle manufactures need to choose hydrogen batteries and cooperate to build nets of hydrogen battery charging stations (nets of electrolysing hydrogen filling stations are easy), for getting advantages of initiating against old manufactures , for their profits, for environment for world.
