OMG - Plug Pwr is done! You're better off investing in Linde or Siemen. I sold my investment in Plug Pwr after taking a 75% loss of my initial investment $2k and built my position with an additional $1500 trying to catch the falling knife. I hope you fared better!
These FCEV makers need to get modern hydrogen technology working for them. I came across a revolutionary system by company called H2IL for making the gas on site - day and night and cheap. This would solves the issues of fuelling stations.

***** tesla is shit, batteries are shit, do you really think that we will have superchargers at every corner? do you really think that just because it is electric, it is 100% ecofriendly? it isnt, it has catched fire more than petrol cars for a week, the batterie making process contaminates more than a petrol car will in his entire lifetime...
***** Tesla only fixed the bad image of electric vehicles by using a panamera like bodystyle instead of MPV which prius had. The future is not again determitted by toyota. tech wise.
The concept of a Fuel Cell is not at all a bad one. It's what type of fuel you use for the reaction. Hydrogen may be the most abundant element in the Universe but separating it from oxygen in water takes more energy to do so then you get out of in the fusion proses in the car. Also, hydrogen is a pain in the ass to store and transport from place to place; and all of this adds up to the costs of its processing all together. A better alternative would be using something like salt water while still using oxygen as a oxidising agent: like the Quant e-Sportlimousine (look it up).
Using a Direct methanol Fuel cell has more advantage than using hydrogen fuel cell, due to the economics of Hydrogen. The power train may consist of a DMFC, a super capacitor bank for high current transient loads, and a regular Li-ion battery pack for surplus storage. Considering an achieved efficiency of 40% for the fuel cell, and the cheap cost of methanol, we could see a revolution in the cost of driving. But these cars may not be cheap initially.
Toyota has made most of its FC patents free to use. Now other companies and countries have started to make their own FC vehicles and other applications. A new era is at dawn!
Keep it up toyota,, fuel cell car can help mother earth to recover from global warming due to burning of fossil fuel.. stop fossil fuel and start hydrogen fuel.
maybe hydrogene fuel cell can be used like a range extender. smal fuel cell stucks, small hydrogene tank for 100 km range. it can solve fast charge problem.electric charge is cheap but it is slow. hydrogene charge is expensive but it is fast.
Well the Mirai is basically a Hybrid car. Its built on the same concept as the Prius with two sources to drive the car A battery pack and Fuel Cell that provides electricity to the electric motors. Hopefully Toyota will build one, eliminate the high voltage battery pack since batteries are designed to be one time use disable devices that can get very expensive to replace.
(Please Answer) Why do we need oxygen for it to mix with Hydrogen to form water if the hydrogen's atoms are being separated by the platinum catalyst and the electrons are being used for electricity? Why do we need Oxygen to help us get water? Doesn't water just go outside through the pipeline? don't we already have electrons from the hydrogen to generate electricity? I really don't understand why we need the Air/Oxygen Intake here?
Hydrogen is not water. The gas is in the h2 form while water is h2o. It needs oxygen to become water. So the fuel cell lets the h2 merge with the oxygen resulting in h2o and an electron that desperately wants to rejoin and by forcing it to tak a specific route you will generate electricity
Tiny but significant error in the graphics at 2:30. For any GCSE chemistry students: Each Hydrogen molecule losses the two negatively charged electrons as shown, BUT positively charged Hydrogen IONS (H+) pass across the gap from the Anode on left to Cathode on right, (and NOT two neutrally charged hydrogen atoms as shown in the video !) Anyone want to tell me what force causes the Hydrogen molecule to split into the electrons and positively charged ions in the first place?
On the left hand side there is a Anode consisting of H2 (Hydrogen Gas) which consist of a single proton and single electron, which makes Hydrogen a neutral atom. So using catalyst we separate that electron from valence shell which is quite! tough because of less distance from the proton so we use Platinum for this purpose as a catalyst. Then using electrolyte we supply that H+ on the other side to the O2 (Cathode) but as there is only H+ ion so we use that electron to form water so we connect battery or output source which further connects to Cathode side and forms H20. This is how it works!
it’s important look at this from a bigger picture. It would be difficult for me to address all that. The worlds largest resource is water mix that with desalination facilities and we have a huge supply of energy. We would be solving two huge problems simultaneously. The need for clean water and energy which is much easier to transport then lithium. Pump the ocean, desalination, channel the water through out the world, sustain agriculture, life, construction and use it for energy through electrolysis. Sunlight, wind, lithium and hydrogen equals sustainability
Seeing as non-degenerating batteries were just invented and Tesla came out with a way you can hot-swap batteries, it doesn't make sense to go this route given the dangers of hydrogen fuel tanks. Still a cool concept, and I'm sure there will still be a use.
Hydrogen fuel cell technology is the solution for High density Population Nations like China, Japan, South Korea, India etc. High density population leads to a lot of population living in Apartments creating challenges for Charging infrastructure & the Charging time associated with EVs can lead to long Queues in these Nations. Infrastructure developed for Hydrogen production & Development for Automobile sector can then eventually be employed for Aviation & Naval industry in the future. Even if Battery technologies reach a stage where the charging time from 0% to 100% capacity for a Tesla3 becomes less than 5 minutes with a minimum range of 500km then obviously EVs will enjoy a monopoly in Automobile sector. But even then Hydrogen fuel cell technology will be needed for Aviation & Naval industry as weight of the battery system cannot be ignored.
And Toyota had an EV long before Tesla as a company existed called the RAV4 EV powered Panasonic NiMH batteries with 90 Mi range at the time. It was released in 1997 the same year as the orignal Prius. Toyota has been an early pioneer in EV power train tech for over 21 years. Tesla nothing special. Just an iphone on wheels that will turn into a money pit like a Mercedes.
@@super-sim1665 They will do once they realise that EV's and all the infrastructure is just not going to make it work. BEV's is totally mobile. No need to charge up stationery. Until EV's can produce the same they are not going to hack it.
Isn't the idea is to get rid of weight I see two tanks. I mean the barbecue gas tank it's pretty heavy unless it's made out of plastic. Even freon gas tank is kinda heavy for commercial refrigeratons. Fork lifts too has a tank and it's heavy and big.
Other than a quicker charge time, I don't see the benefit. Electricity is everywhere, why would we build out a hydrogen network? Plus, hydrogen is more expensive than electricity.
I wonder if you use hydrogen pumps station or bottle of water to fill up

Does explain the two most important question: How much water and petrol is used to produce hydrogen and to transport it. And what do we do with the water exhaustion which might not be consuming oil or polluting but definitely wastes water...
You know toyota keep up the good work. by the way a word of advice if i were you id invest heavily in anion exchange membrane,s there much cheeper than proton exchange membranes and more efficient.i think you as a company can benifit from it on day to day basis. so please consider it.
Nope, shooting at a tank filled with petrol will not cause explosion. Petrol has to be VAPOURISED then mixed with certain proportion of oxygen to cause an explosion. It’s very unlikely for explosion, where fire is more likely. As for hydrogen, it just fucking explodes right away.
Electrical energy to produce hydrogen then convert back to electricity:) with energy loss during the conversion process. I’m sticking to battery powered cars
@@arinaZamorochka it is an option but whether promising or not is entirely dependent on costs. There’s added costs for additional complexity, that’s why the original comment above referred to energy loss.
Toyota is using big fuel cell stack and small battery. I want a PHEV with a small fuelcell stack (25ish kW) and BIG battery (16+ kWh) with a plug. Think of a Chevy Volt but with small fuelcell stack instead of an ICE for a generator.
The fuel can be made to resist harsh conditions, including temperature, a lot of engines uses Turbocharges to bring in oxygen regardless of the atmosphere pressure that may have change with the weather or high altitudes, so its already been solve.
What about airplanes Jet engines ? What would be more efficient ? Burning the H2 in a modified combustion chamber or harnessing that energy from a fuel cell and then power a superconducting motor to turn the fan ?
Electrolysis is a promising option for hydrogen production from renewable resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer. Electrolyzers can range in size from small, appliance-size equipment that is well-suited for small-scale distributed hydrogen production to large-scale, central production facilities that could be tied directly to renewable or other non-greenhouse-gas-emitting forms of electricity production.☀️⚡💧
No, its just an electric car, it just produces its own electricity using Electrolisis, it takes oxygen from the enviroment, we give it Hydrogen, and puff, electricity.
To reduce production costs, a combination of sodium sulfide solid-state batteries and PMEF cells, which use liquid ammonia instead of hydrogen, along with solid oxide cells using ethanol, biodiesel, and methanol, can be used. The market should focus on plug-in hybrids for mass-market vehicles, such as cars, vans, small to mid-size trucks, and motorcycles priced under 30000 EUR. Wireless high-voltage charging ranging from 150 to 450 kWh should also be considered. This approach can be used for larger transportation vehicles, such as ships, railways, and airplanes, as well as heavy-duty vehicles like mining and construction equipment and various types of trucks. By using the same hydrogen and gas station infrastructure for wireless charging on all public and private spaces, a separate charging box is not needed. A parking meter can control one or more rows of wireless charging spots. With this approach, a single charge can provide better autonomy as the battery can reach up to 800 miles and is not affected by weather, made out of non-combustible solid electrolyte. Another 443 miles can be achieved from one refill, and you don't need to charge your battery as frequently because the electricity produced by using ethanol or ammonia is stored in the battery. Therefore, after a few refills at a fuel station and a visit to the grocery shop, your battery will be charged as each private and public parking has fast wireless charging pads.
Plug in Hydrogen hybrid, I mean an EV where the electric power in feed both by plug in in the grid and by an Hydrogen FC. Is it possible? Are there researches in this field?
YES TOYOTA...... PLEASE BRING THIS TECH TO THE MARINE WORLD..... AND ESPECIALLY CARGO SHIPS, SINCE 50 SHIPS = ALL THE CARS ON EARTH. AND WE HAVE 50.000 SHIPS OUT THERE.... THEY ARE THE BIG POLLUTERS.
The fundamental problem with Hydrogen Fuel cells is to get hydrogen. Current methods of extracting hydrogen is to use oil or electrolysis, and both methods are expensive.
What's about water 💧💦 Will you leave it through tail pipe Pleases reply Toyota I love toyota cars Especially toyota Supra 💜❤💖💜❤💓💖💜❤💖💓💖💜❤💖💓💖💜❤💓💜❤💓💜❤💓💜❤💖💖💓
Lets say you have 100 kWh hours of AC electricity How efficient are fuel cell cars? You do AC-DC to conversion 95% with efficiency. Then you do electrolysis with 75% efficiency to split the water. Then you Compress and transport the hydrogen with 90% and 80% efficiency. Fuel Cell cars are about 50% efficient to turn H2 to electricity. Electric cars about 90% efficient. If you do the math 23 kWh of energy is used to move the vehicle so overall efficiency is 23%. How efficient are battery powered cars? You have to transfer the energy from grid to house which is about 90% efficient. You do AC-DC to conversion 95% with efficiency. Battery charging is 90% efficient. Electric cars about 90% efficient. If you do the math 69 kWh of energy is used to move the vehicle so overall efficiency is 69%. So overall efficiency with battery powered cars is about 3 times greater than hydrogen cars. It can go same distance with only third of energy that hydrogen car uses. That is huge difference.
I wish hydrogen fuel cell cars were more readily available throughout the UK. Their are only about 3 hydrogen models available here and most hydrogen fuel filling stations are in the south east of England. I would like to see some of these car manufacturers offer a service to convert a petrol or diesel engined car to a hydrogen fuel celled car. That might be more cost effective compared to manufacturing an entire new car. This would help drive the demand for hydrogen which would then eventually drive demand for brand new cars to be hydrogen fuel celled cars. Hydrogen fuel would have to be made more readily available throughout the UK as the demand increases. I for one would love to own a hydrogen fuel celled car and I would be happy to recommend anybody to have one.
+ The question is .... how many miles per $ can you get with this technology ? Although I'm aware hydrogen prices will fluctuate since most of the hydrogen produced comes from hydrocarbons, but how does it compare with gasoline ?
What a detailed scientific explanation
HYDROGEN AS BATTERIES : 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 :
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 lifespand, 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/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 thay 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 ofcourse. 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/ Lifespan :
Hydrogen batteries have practically forever life span.
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.
4.6/ Influence of environment temperature :
Hydrogen batteries never fear environment temperatures.
Lithium batteries fear environment temperature. Even in some seasons you can not or your ineffectively use lithium batteries.
Conclusion : hydrogen batteries win.
4.7/ 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.
4.8/ Synchronyze 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 intermitten clean energy/renewable energy.
But electric charging stations can not pick up times. High power electric charging stations terribly conflict with intermitten shedules of clean energy/renewable energy. The more higher power electric charging station in quick charging mode, the more terribly it conflicts with intermitten 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, and right choice.
Toyota is the best company can not say enough with the quality of their products.
2014:nope
2019: we need to educate people

I like the concept. Its basically a Hybrid Fuel Cell/Battery electric vehicle. Same principals as the Prius. Hopefully as tank capacity increases, the battery pack can be fully eliminated and just only need a 12 volt one for the computers and electronic accessories.

OMG - Plug Pwr is done! You're better off investing in Linde or Siemen. I sold my investment in Plug Pwr after taking a 75% loss of my initial investment $2k and built my position with an additional $1500 trying to catch the falling knife. I hope you fared better!
Just awesome what a detailed explanation!
We need these today!
We do....
These FCEV makers need to get modern hydrogen technology working for them. I came across a revolutionary system by company called H2IL for making the gas on site - day and night and cheap. This would solves the issues of fuelling stations.
That would be a game changer by having on site hydrogen refineries
HYDROGEN AS BATTERIES : 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 :
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 lifespand, 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/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 thay 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 ofcourse. 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/ Lifespan :
Hydrogen batteries have practically forever life span.
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.
4.6/ Influence of environment temperature :
Hydrogen batteries never fear environment temperatures.
Lithium batteries fear environment temperature. Even in some seasons you can not or your ineffectively use lithium batteries.
Conclusion : hydrogen batteries win.
4.7/ 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.
4.8/ Synchronyze 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 intermitten clean energy/renewable energy.
But electric charging stations can not pick up times. High power electric charging stations terribly conflict with intermitten shedules of clean energy/renewable energy. The more higher power electric charging station in quick charging mode, the more terribly it conflicts with intermitten 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, and right choice.
Real clean energy which is NOT being supported by governments 😞
Right on Toyota, It will be cool to what a HFCV Tacoma pickup will look like!
Congratulations! This aged well
now I have seen the future.
The future has already been here, its called Tesla Motors
***** tesla is shit, batteries are shit, do you really think that we will have superchargers at every corner? do you really think that just because it is electric, it is 100% ecofriendly? it isnt, it has catched fire more than petrol cars for a week, the batterie making process contaminates more than a petrol car will in his entire lifetime...
***** Tesla only fixed the bad image of electric vehicles by using a panamera like bodystyle instead of MPV which prius had. The future is not again determitted by toyota. tech wise.
yann Cruz " it isnt, it has catched fire more than petrol cars for a week" such a stupid lie.
yann Cruz and the future can be both technologies.... they will coexist.
The concept of a Fuel Cell is not at all a bad one. It's what type of fuel you use for the reaction. Hydrogen may be the most abundant element in the Universe but separating it from oxygen in water takes more energy to do so then you get out of in the fusion proses in the car. Also, hydrogen is a pain in the ass to store and transport from place to place; and all of this adds up to the costs of its processing all together. A better alternative would be using something like salt water while still using oxygen as a oxidising agent: like the Quant e-Sportlimousine (look it up).
Hazerion good idea.
Thanks! I'm hoping to become an automotive engineer in the future, specializing in fule cell/electric car technology
Using a Direct methanol Fuel cell has more advantage than using hydrogen fuel cell, due to the economics of Hydrogen. The power train may consist of a DMFC, a super capacitor bank for high current transient loads, and a regular Li-ion battery pack for surplus storage. Considering an achieved efficiency of 40% for the fuel cell, and the cheap cost of methanol, we could see a revolution in the cost of driving. But these cars may not be cheap initially.
I bet the amount of energy it requires is not as much as the energy required to get lithium 🤣
Awesome ! Respect #Toyota!
Explanations do not get simpler than this!
Wow!
THANK YOU! This is the futture
!
Toyota has made most of its FC patents free to use. Now other companies and countries have started to make their own FC vehicles and other applications. A new era is at dawn!
It's so sad to see such little views... And hydrogen cars active today. All the time we buy it, they'll sell it.
The future is certainly bright
Excelente video!
This is the Future!!!
Toyota!!!
awesome. Revolutionary. Toyota delivers us the future in now! Hybrid and fuelcell combination. bye tesla.
sorry, Tesla and EV's arent going anywhere.
Congratulations sir and all the very best for your success and happiness ❣️
Thank you from 'H2 Innovation Lab' H2IL - innovative technology for a green sustainable hydrogen future.
TOYOTA MIRAI IS AN IDEAL CAR WITH A CLEAN ELECTRIC DRIVE WITHOUT LIMITING THE NEED TO CHARGE VERY SKILLFUL 👌🏻🙂👍🏻
but does have the limitation of not having anywhere to refuel..
Splendid explaination. Can you tell please how to prepare a model at fsc level.
Perfect video
This was almost three minutes that I'll never get back.
I won't live to the time I'd buy a hydrogen fueled car, but it's nice to dream.
hey, still goin'
@@alexmo930 damn
Keep it up toyota,, fuel cell car can help mother earth to recover from global warming due to burning of fossil fuel.. stop fossil fuel and start hydrogen fuel.
Absolutely true 👍👍.
Let's make a better world .
What a explanation ❤
Excellent
I love Toyota
This tech dream is like fusion energy - always 10 years in the future.
How safe are you in case of a crash? And charging station not blowing up?
Question, how fast can these cars go?
maybe hydrogene fuel cell can be used like a range extender. smal fuel cell stucks, small hydrogene tank for 100 km range. it can solve fast charge problem.electric charge is cheap but it is slow. hydrogene charge is expensive but it is fast.
deniz vapur
Well the Mirai is basically a Hybrid car. Its built on the same concept as the Prius with two sources to drive the car A battery pack and Fuel Cell that provides electricity to the electric motors. Hopefully Toyota will build one, eliminate the high voltage battery pack since batteries are designed to be one time use disable devices that can get very expensive to replace.
Very nice
beautiful technology
(Please Answer) Why do we need oxygen for it to mix with Hydrogen to
form water if the hydrogen's atoms are being separated by the platinum
catalyst and the electrons are being used for electricity? Why do we
need Oxygen to help us get water? Doesn't water just go outside through
the pipeline? don't we already have electrons from the hydrogen to
generate electricity? I really don't understand why we need the
Air/Oxygen Intake here?
Hydrogen is not water. The gas is in the h2 form while water is h2o. It needs oxygen to become water. So the fuel cell lets the h2 merge with the oxygen resulting in h2o and an electron that desperately wants to rejoin and by forcing it to tak a specific route you will generate electricity
let the future begin
H2 cars are very inefficient
Tiny but significant error in the graphics at 2:30. For any GCSE chemistry students: Each Hydrogen molecule losses the two negatively charged electrons as shown, BUT positively charged Hydrogen IONS (H+) pass across the gap from the Anode on left to Cathode on right, (and NOT two neutrally charged hydrogen atoms as shown in the video !)
Anyone want to tell me what force causes the Hydrogen molecule to split into the electrons and positively charged ions in the first place?
On the left hand side there is a Anode consisting of H2 (Hydrogen Gas) which consist of a single proton and single electron, which makes Hydrogen a neutral atom. So using catalyst we separate that electron from valence shell which is quite! tough because of less distance from the proton so we use Platinum for this purpose as a catalyst. Then using electrolyte we supply that H+ on the other side to the O2 (Cathode) but as there is only H+ ion so we use that electron to form water so we connect battery or output source which further connects to Cathode side and forms H20.
This is how it works!
it’s important look at this from a bigger picture. It would be difficult for me to address all that. The worlds largest resource is water mix that with desalination facilities and we have a huge supply of energy. We would be solving two huge problems simultaneously. The need for clean water and energy which is much easier to transport then lithium. Pump the ocean, desalination, channel the water through out the world, sustain agriculture, life, construction and use it for energy through electrolysis. Sunlight, wind, lithium and hydrogen equals sustainability
Seeing as non-degenerating batteries were just invented and Tesla came out with a way you can hot-swap batteries, it doesn't make sense to go this route given the dangers of hydrogen fuel tanks. Still a cool concept, and I'm sure there will still be a use.
This is what i want to know, detail and easy understand hidrogen car is work
Hydrogen fuel cell technology is the solution for High density Population Nations like China, Japan, South Korea, India etc.
High density population leads to a lot of population living in Apartments creating challenges for Charging infrastructure & the Charging time associated with EVs can lead to long Queues in these Nations.
Infrastructure developed for Hydrogen production & Development for Automobile sector can then eventually be employed for Aviation & Naval industry in the future.
Even if Battery technologies reach a stage where the charging time from 0% to 100% capacity for a Tesla3 becomes less than 5 minutes with a minimum range of 500km then obviously EVs will enjoy a monopoly in Automobile sector.
But even then Hydrogen fuel cell technology will be needed for Aviation & Naval industry as weight of the battery system cannot be ignored.
Oh look! Now Toyota is investing in BEV! Trying to catch up Tesla?!
"Fuel Cell are the future and they always will be"
Jaden Mars Toyota Prius since 1997. Tesla? Nothing new...
And Toyota had an EV long before Tesla as a company existed called the RAV4 EV powered Panasonic NiMH batteries with 90 Mi range at the time. It was released in 1997 the same year as the orignal Prius. Toyota has been an early pioneer in EV power train tech for over 21 years. Tesla nothing special. Just an iphone on wheels that will turn into a money pit like a Mercedes.
Toyota payroll? It's about 50 years behind Tesla, no one sells hydrogen.
@@super-sim1665 No one sells Hydrogen yet. 40 places in California do. You are right though it is what limits fuel cell vehicles currently.
@@super-sim1665 They will do once they realise that EV's and all the infrastructure is just not going to make it work. BEV's is totally mobile. No need to charge up stationery. Until EV's can produce the same they are not going to hack it.
Isn't the idea is to get rid of weight I see two tanks. I mean the barbecue gas tank it's pretty heavy unless it's made out of plastic. Even freon gas tank is kinda heavy for commercial refrigeratons. Fork lifts too has a tank and it's heavy and big.
Other than a quicker charge time, I don't see the benefit. Electricity is everywhere, why would we build out a hydrogen network? Plus, hydrogen is more expensive than electricity.
Brillant! 💪🥳
I wonder if you use hydrogen pumps station or bottle of water to fill up
Does explain the two most important question: How much water and petrol is used to produce hydrogen and to transport it.
And what do we do with the water exhaustion which might not be consuming oil or polluting but definitely wastes water...
Roflol!
It means what????
Only if hydrogen gas station can be increased..this technology will be far more competitive than electric vehicles.
You know toyota keep up the good work. by the way a word of advice if i were you id invest heavily in anion exchange membrane,s there much cheeper than proton exchange membranes and more efficient.i think you as a company can benifit from it on day to day basis. so please consider it.
Hydrogen is easiest burning in the fuel power classes, equal to have the most explosive thing in car.
Nope, shooting at a tank filled with petrol will not cause explosion. Petrol has to be VAPOURISED then mixed with certain proportion of oxygen to cause an explosion. It’s very unlikely for explosion, where fire is more likely. As for hydrogen, it just fucking explodes right away.
Great to see that inplix has new instructions to save my money and energy to build it.
This is great.
If the cost of H2 decreased, would H2 fuel cell cars win electric cars?
Electrical energy to produce hydrogen then convert back to electricity:) with energy loss during the conversion process. I’m sticking to battery powered cars
That’s the problem, hydrogen gas is not freely available.
@@ismailnyeyusof3520 Electrolysis is a promising option for hydrogen production from renewable resources.
@@arinaZamorochka it is an option but whether promising or not is entirely dependent on costs. There’s added costs for additional complexity, that’s why the original comment above referred to energy loss.
Well explain.
Toyota is using big fuel cell stack and small battery.
I want a PHEV with a small fuelcell stack (25ish kW) and BIG battery (16+ kWh) with a plug. Think of a Chevy Volt but with small fuelcell stack instead of an ICE for a generator.
you can't scale batteries linearly.
Majid Ahmed what does that mean? And you do know I wrote that message 2 years ago lol
How does that work in the winter conditions? How does it prevent the fuel cell from damaging if you leave the car outside in freezing conditions (
The fuel can be made to resist harsh conditions, including temperature, a lot of engines uses Turbocharges to bring in oxygen regardless of the atmosphere pressure that may have change with the weather or high altitudes, so its already been solve.
What about airplanes Jet engines ? What would be more efficient ? Burning the H2 in a modified combustion chamber or harnessing that energy from a fuel cell and then power a superconducting motor to turn the fan ?
Then where could i get the H2 from? It would be economically challenging.
Electrolysis is a promising option for hydrogen production from renewable resources. Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This reaction takes place in a unit called an electrolyzer. Electrolyzers can range in size from small, appliance-size equipment that is well-suited for small-scale distributed hydrogen production to large-scale, central production facilities that could be tied directly to renewable or other non-greenhouse-gas-emitting forms of electricity production.☀️⚡💧
I want to see and invest in solar panel electric self-driving vehicles.
So hydrogen atoms just release electrons to generate power? I thought there was some combustion of some sort....
Combustion involves transfer of electrons from one set of atoms to another.
So basically fuel cell technology utilize hydrogen fuel with electric battery to recharge itself 90% efficiency. It's a hybrid hydrogen with battery
No, its just an electric car, it just produces its own electricity using Electrolisis, it takes oxygen from the enviroment, we give it Hydrogen, and puff, electricity.
-110 efficiency of a electric car and you get to put one of the most explosive gases in the world near the kids seat.
Super -sim and the alternative is that you put one of the most flammable and energy dense liquids under your kids seat.
To reduce production costs, a combination of sodium sulfide solid-state batteries and PMEF cells, which use liquid ammonia instead of hydrogen, along with solid oxide cells using ethanol, biodiesel, and methanol, can be used. The market should focus on plug-in hybrids for mass-market vehicles, such as cars, vans, small to mid-size trucks, and motorcycles priced under 30000 EUR. Wireless high-voltage charging ranging from 150 to 450 kWh should also be considered. This approach can be used for larger transportation vehicles, such as ships, railways, and airplanes, as well as heavy-duty vehicles like mining and construction equipment and various types of trucks. By using the same hydrogen and gas station infrastructure for wireless charging on all public and private spaces, a separate charging box is not needed. A parking meter can control one or more rows of wireless charging spots. With this approach, a single charge can provide better autonomy as the battery can reach up to 800 miles and is not affected by weather, made out of non-combustible solid electrolyte. Another 443 miles can be achieved from one refill, and you don't need to charge your battery as frequently because the electricity produced by using ethanol or ammonia is stored in the battery. Therefore, after a few refills at a fuel station and a visit to the grocery shop, your battery will be charged as each private and public parking has fast wireless charging pads.

So cool
Plug in Hydrogen hybrid, I mean an EV where the electric power in feed both by plug in in the grid and by an Hydrogen FC. Is it possible? Are there researches in this field?
YES TOYOTA...... PLEASE BRING THIS TECH TO THE MARINE WORLD..... AND ESPECIALLY CARGO SHIPS, SINCE 50 SHIPS = ALL THE CARS ON EARTH. AND WE HAVE 50.000 SHIPS OUT THERE.... THEY ARE THE BIG POLLUTERS.
awesome!!
The fundamental problem with Hydrogen Fuel cells is to get hydrogen. Current methods of extracting hydrogen is to use oil or electrolysis, and both methods are expensive.
Arun Kottolli electrolysis will significantly come down in price as electricity becomes cheaper.
Also 10% hydrogen is leaked into atmosphere from production supply chain before it gets to your car and can contribute to Ozone depletion
Made me smile
TOYOTA 😎👍🏻
This Fuel Cell Motor is AC Tesla Drive Units
what the name software used 3d????

How to mitigate the risk of an explosion?
hydrogen cannot explode because explode is H24
How do mitigate total batteries melt down?
Ever seen an electric car start on fire?
Ever seen a gas tank explode?
Do you still want to ask your question? Lol
What's about water 💧💦
Will you leave it through tail pipe
Pleases reply Toyota
I love toyota cars
Especially toyota Supra 💜❤💖💜❤💓💖💜❤💖💓💖💜❤💖💓💖💜❤💓💜❤💓💜❤💓💜❤💖💖💓
No we will bottle it and sell it at 7-11.
it's water vapour. not liquid water
I invested in Plug Power after seeing this video.
how about a distilled water pump at the fuel station and a steam powered car? - that just flies!
Lets say you have 100 kWh hours of AC electricity
How efficient are fuel cell cars?
You do AC-DC to conversion 95% with efficiency. Then you do electrolysis with 75% efficiency to split the water. Then you Compress and transport the hydrogen with 90% and 80% efficiency. Fuel Cell cars are about 50% efficient to turn H2 to electricity. Electric cars about 90% efficient. If you do the math 23 kWh of energy is used to move the vehicle so overall efficiency is 23%.
How efficient are battery powered cars?
You have to transfer the energy from grid to house which is about 90% efficient. You do AC-DC to conversion 95% with efficiency. Battery charging is 90% efficient. Electric cars about 90% efficient. If you do the math 69 kWh of energy is used to move the vehicle so overall efficiency is 69%.
So overall efficiency with battery powered cars is about 3 times greater than hydrogen cars. It can go same distance with only third of energy that hydrogen car uses. That is huge difference.
FUTURE
Wow!
This will explain everything for you guys, www.toyota.com/fuelcell/
I wish hydrogen fuel cell cars were more readily available throughout the UK. Their are only about 3 hydrogen models available here and most hydrogen fuel filling stations are in the south east of England.
I would like to see some of these car manufacturers offer a service to convert a petrol or diesel engined car to a hydrogen fuel celled car. That might be more cost effective compared to manufacturing an entire new car. This would help drive the demand for hydrogen which would then eventually drive demand for brand new cars to be hydrogen fuel celled cars.
Hydrogen fuel would have to be made more readily available throughout the UK as the demand increases.
I for one would love to own a hydrogen fuel celled car and I would be happy to recommend anybody to have one.
what about in high altitude driving, where oxygen level is so low
Future car
So, what does it do at medium load?
One must presume that little or no charge is going into or out of the battery.
+ The question is .... how many miles per $ can you get with this technology ?
Although I'm aware hydrogen prices will fluctuate since most of the hydrogen produced comes from hydrocarbons, but how does it compare with gasoline ?
