Comments by "Simon" (@Simon-dm8zv) on "Toyota Mirai review: the hydrogen car that 'urinates' 😂" video.

@makr0295 Hydrogen cars will always remain horribly inefficient, no matter how much money you throw at it.
44
It will never become efficient enough. Hydrogen is a dead end road.
20
@WhiteWolfos Of course you can tweak a little here and there but overall efficiency will always remain terribly low. The biogas-methane to hydrogen route is really one of the dumbest energy solutions I have ever heard of. There are so many losses in the whole process. And what are you talking about regarding cities and EVs? Public charging works perfectly fine where I live. You don’t need your own garage or driveway to charge an electric vehicle. Last thing: it is widely known Volkswagen has declared clearly they are not going to invest in hydrogen at all anymore. It’s all about battery electric now.
20
@--Nath-- exactly.
13
@gordonnorris4202 EVs were efficient from day 1.
8
Hydrogen is horribly inefficient and therefore not a great solution compared to EVs.
4
@shanginadildo I said energy efficient.
4
You mean in Tokyo there are still hydrogen busses. In the meantime many countries have moved on to battery electric busses as they make much more sense and are cheaper to run. Also, using bio methane for hydrogen production is relatively nice, it is still very wasteful to use it in vehicles. The world needs vast amounts of bio methane and renewable hydrogen for industrial applications where fossil methane and hydrogen has been used for decades.
3
The push for hydrogen vehicles only is one of the last spasms of the fossil industry.
3
@kalvds9345 Although small improvements are definitely possible, hydrogen cars will always remain very inefficient due to simple laws of physics. The Volvo report is far off. More recent reports prove that an EV only needs 30.000 km to compensate for its production emissions compared to an equally sized ICE car. This number will go down in the coming years. A hydrogen car is inefficient from day one and remains that way its entire life.
3
You sir are correct.
3
@shanginadildo EVs were very energy efficient from day one.
3
@shanginadildo That it uses relatively small amounts of energy per kilometer. This has always been the case, unlike hydrogen cars.
3
Nope. Hydrogen cars are inefficient by nature. This will always remain so.
3
@CorrespondenceTheory There are countless cities around the world using battery electric city busses. These cities simply chose battery electric and not hydrogen because it's better and cheaper. They charge at night and at longer stops using catenary charging systems. It's not problem at all and definitely not a reason to use inefficient hydrogen. It just doesn't make sense in road vehicles and definitely not city busses.
2
It will never be a mainstream thing
2
Current generation EVs are absolutely fine for long journeys.
2
Battery electric vehicles will get us much faster to net zero because their efficiency.
2
No it should not. Hydrogen is terribly inefficient and therefore unable to make a decent dent in CO2 emissions.
2
Exactly! Hydrogen is over.
2
@thebrowns5337 Most early Teslas are doing absolutely fine.
2
@bryanduncan6178 Not really. A wide adoption of hydrogen vehicles would mean an insane increase of electricity consumption and thus massive CO2 emissions.
2
@RonanB99 Green hydrogen does not exist and will not exist in any serious amounts the coming decades. The small amounts of green hydrogen that will be available should be used in situations where pure electric is not an option and as a feedstock for the chemical industry. Using green hydrogen for vehicles is a horrible waste of precious renewable energy. And guess what, hydrogen cars require lithium, cobalt, nickel and platinum.
2
@RonanB99 Still an insane waste of energy. You can charge 3 times the number of EVs with the same amount of renewable electricity. It's a dumb technology. In the end green hydrogen would require 3 times as many wind turbines and solar panels. Now think again about all the materials required.
2
@RonanB99 Yeah possibly, but it should be minimised as much as possible. Passenger cars is a big no no in any case, and so are public transport busses and pretty soon trucks. Heavy machinery and eventually aircraft is fine.
2
@RonanB99 It's simple. Electric busses with a range of 400 to 500 km already exist. Fast chargers (1 MW) than can charge these things in half an hour will be here much faster than hydrogen ever gets a chance to develop. Same for trucks. Governments often have no clue about the realities of hydrogen or are advised by the fossil industry.
2
@RonanB99 Sure, but infrastructure isn't there and hydrogen does not make sense in cities (short range). Long range electric busses and chargers will be here before hydrogen gets a chance and that's a good thing.
2
 @RonanB99 Not really. Current hydrogen busses are the remains of a short hype from a few years a go. Meanwhile electric busses are selling like hot cakes.
2
@RonanB99 It's sad to see local governments in the UK still fall for the hydrogen trap. There is no business case for hydrogen city busses. Oh well, it will just be a matter of time before they realise battery electric busses are far cheaper to run.
2
@paulbedichek2679 Well it results in lower emissions so I don't see a problem for the time being. By the way, hydrogen cars consume far more electricity so if I were the coal and natural gas industry I would promote hydrogen instead...
2
Nope
2
@klasykapolskiegohh8798 it’s not. Faster refueling is the one and only advantage.
2
@klasykapolskiegohh8798 I am not.
2
@mb7392 correct
2
@carlosandleon Nope because hydrogen vehicles are intrinsically inefficient.
2
@allentoyokawa9068 But at the same time they are planning on massively expanding the number of chargers.
2
But it requires A LOT of energy to harvest these H-atoms.
2
Not at all. It’s super inefficient and super expensive.
2
@rekhakuttappa5120 I just explained to John why that was not the case.
2
@jonasweber9408 Exactly.
2
And that's where the advantages stop..
2
@troyheffernan1261 Again, it is terribly inefficient compared to electric motors and batteries. Unfortunately rockets require combustion so in that case it is acceptable.
2
@troyheffernan1261 I quote: "The 1016-mile range of the XP-1 is possible due to a bigger hydrogen tank than other hydrogen-powered vehicles such as the Toyota Mirai, or the Honda Clarity." So that does not make it efficient at all.
2
Nope. Driving on hydrogen is simply too inefficient.
2
@lolololo-cx4dp I don’t. Hydrogen fuel cell vehicles create a lot of CO2 during production of hydrogen.
2
Nope we do not. Too inefficient.
1
Because electric motors are FAR more efficient.
1
You forgot about the insane lack of efficiency of hydrogen cars.
1
@ArmaDino22 You need breaks on long drives anyway.
1
Where did you get this bullshit. Hydrogen is dead on arrival and will always remain so. Battery electric is the only solution that makes sense.
1
There is no energy created.
1
It’s not. Hydrogen is far too inefficient.
1
@gaborpapp9388 Excellent argument.
1
@gaborpapp9388 Battery electric obviously.
1
@gaborpapp9388 Of course.
1
@SHAMzila85 There is lots of electronics, platinum and even batteries required to build hydrogen cars. Battery production emissions average at about 100 kg of CO2 per kWh. This is compensated for after about 4 years of driving. A hydrogen car is inefficient its entire life - causing lots of CO2 emissions from hydrogen production.
1
@SHAMzila85 It’s just simple physics. Hydrogen has aways been and will always remain very inefficient compared to battery electric. Therefore battery electric will always cause less CO2 emissions.
1
@SHAMzila85 Lol electric cars have been working perfectly fine in the real world for the past 10 years. Toyota is also investing in EVs.
1
@SHAMzila85 Petrol stations with fast chargers can charge a vehicle within half an hour. Far cheaper and easy to scale. No problem at all. In the country where I live chargers are everywhere already and they are expanding on a daily basis.
1
@SHAMzila85 resulting in far higher CO2 emissions lol
1
@SHAMzila85 Material mining only happens once and is far less of a problem than CO2.
1
@SHAMzila85 Haha the famous child labour argument. Guess who is still one of the biggest consumers of cobalt? The oil industry. Cobalt is in many different electronic products, including hydrogen cars.
1
@SHAMzila85 The point is that shady mining activities have nothing specifically to do with electric cars so your argument makes no sense.
1
@SHAMzila85 There is no hydrogen infrastructure.
1
@thebrowns5337 Guess what, hydrogen cars also require lithium and much rarer materials like platinum. Good luck with that.
1
Lol they are clearly not.
1
@Lewis1995 Too inefficient and complex.
1
@richards6854 It is terribly inefficient.
1
@richards6854 You cannot compare EV batteries to phone batteries at all. Due to sophisticated thermal management EV batteries easily last 10+ years. Also: hydrogen is a terribly cumbersome solution to lack of grid capacity.
1
not in the slightest
1
Nope. Hydrogen is too inefficient.
1
@TheMrbc74 Only slightly. Hydrogen car efficiency will never get anywhere near that of an EV due to laws of physics. Electrons are also plentiful.
1
@TheMrbc74 There is no shortage of materials at all. Fuel cells require materials like platinum to make. Batteries will be recycled obviously.
1
But a lot of carbon is created when hydrogen is produced.
1
If you knew some basic physics you would understand why.
1
They might be interesting but they are needlessly complex and inefficient.
1
@carlosandleon Hydrogen is not a future technology for passenger vehicles and will never be. It’s simply stupid.
1
@mohamadaliffshafiqazizan2788 Still requires a lot of energy.
1
@mohamadaliffshafiqazizan2788 I googled it, production is only 60% efficient and after that you still need to compress and transport it which also involves a lot of losses.
1
@mohamadaliffshafiqazizan2788 Laws of physics don't change. Efficiency will always remain low compared to battery electric cars.
1
@mohamadaliffshafiqazizan2788 FCEV require 3 times as much power...
1
@mohamadaliffshafiqazizan2788 probably inefficient as well. Cannot find numbers.
1
@mohamadaliffshafiqazizan2788 Physics don’t change
1
You are wrong.
1
Nope it's not! Hydrogen is a stupid solution.
1
@josefmalina3273 Too inefficient
1
@josefmalina3273 It’s not.
1
@josefmalina3273 Replace [DOT] by a real dot in the link above.
1
Apparently links get removed automatically...
1
Hydrogen cars require platinum, cobalt, nickel and lithium as well...
1
@waldnew True, but many other materials are needed for the extra required wind turbines and solar panels.
1
No they won't. Current EVs are already better than hydrogen cars.
1
@michaelr5322 Charging does not have to take hours haha
1
Nope it is not
1
Exactly
1
Hydrogen is mindbogglingly inefficient and therefore a stupid solution for cars and heating.
1
@SniQ3 How to say you now nothing about EVs without saying you know nothing about EVs.
1
@SniQ3 Well at least that proves why you know nothing about EVs.
1
Spot on.
1
Not a single way.
1
Fuel roads? What?
1
@Gor133 Glow in the dark?
1
Hydrogen is a mindbogglingly stupid technology.
1
@kalvds9345 It's the truth.
1
@kalvds9345 Pretty much any kind of vehicle you see driving down on the road will eventually be battery electric. The main draw back of hydrogen is not the lack of refuelling stations but the total lack of efficiency. A battery electric vehicle only requires 1/3rd of the amount of energy to drive.
1
@kalvds9345 Nope, research was based on average CO2 emissions per kWh. It’s easy. There is also plenty of data on battery production emissions. Regarding hydrogen: Lets say average electricity is 450 grams of CO2 per kWh. A hydrogen car consumes about 0,6 kWh per kilometer. That is 270 grams of CO2 per km. A diesel car consuming 1 liter in 20 km produces about 150 grams of CO2 per km.
1
@kalvds9345 I just proved that hydrogen is a dead end road. All vehicles will be battery electric. Good luck waiting for hydrogen.
1
Because it would require a lot of energy. Where would that energy come from?
1
It is horribly inefficient...
1
If you had educated yourself you would know that driving electric is always less polluting even on 100% fossil electricity.
1
Unlikely. Driving on hydrogen will always remain far more expensive due to its very low efficiency. In daily life you do not wait for your car to charge because it happens at night or when you are at work 9 times out of 10.
1
@HarrisonAdAstra Well said. The $2 hydrogen story is a myth.
1
But very inefficient.
1
Lol
1
It’s not. And the only thing that can be reused from existing fuel stations is the canopy and the shop... It’s far easier to build fast chargers.
1
@LynxEng correct, but that is the one and only advantage.
1
@LynxEng The car is only marginally lighter than a comparable EV. Charging times are no problem in real life as it mostly happens at night and during long road trips you need breaks anyway. A battery/hydrogen hybrid sounds cool on paper but is quite useless. The added fuel tanks and cells add weight, take up space and are expensive. Could as well just have added more batteries to the vehicle.
1
@LynxEng Public chargers of course. This is very normal around where I live.
1
@LynxEng Simply chargers in the street and yes, also at apartment blocks. The number of chargers is in ratio with the number of EVs and is expanded on a daily basis. Look up The Netherlands.
1
Until they realize that they only drive a few hundred miles per day which is easily possible in an EV.
1
No it won't lol.
1
Hydrogen is not efficient enough.
1
This vehicle will tow just as fine as a proper EV.
1
Hydrogen makes zero sense for passenger cars.
1
@fallout0624 No they have not. Efficiency will always remain very bad.
1
Lol so how do you think hydrogen is made?
1
@trishansadhukhan2680 Exactly. And that requires THREE TIMES as much energy as an electric car requires.
1
Lol hydrogen is so horribly inefficient CO2 emissions are far higher than any EV. EV charging in cities simply happens at public chargers, no problem at all.
1
@utha2665 It’s just a matter of physics. Hydrogen will always remain far less efficient. Hydrogen vehicles are not much lighter than EVs and when you want to extend their range you have to make the tanks even bigger or increase the pressure even more, resulting in even lower efficiency. Also, hydrogen cars consume a lot more electricity and are therefore not a solution for grid congestion. Hydrogen makes zero sense in passenger cars. Possibly in long range trucking, shipping and aviation.
1
No we don’t
1
Lol not at all. Hydrogen may be very common but it requires shit loads of energy to capture. There is plenty of lithium en batteries will eventually be recycled of course.
1
@thebrowns5337 Of course you can, but it requires far less energy to simply charge your electric car at home. A hydrogen car may look better regarding the environment, but is not. They are so incredibly inefficient that emissions from electricity are far higher than the production emissions of an EV. By the way: hydrogen cars require lithium, cobalt, nickel and platinum to manufacture.
1
Hydrogen is super inefficient. It is still an electric car by the way.
1
@troyheffernan1261 Even more inefficient.
1
It will always remain terribly inefficient.
1
@psychoticcapybara9362 The future will not change laws of physics. Hydrogen cars were inefficient 20 years ago and they still are.
1
@psychoticcapybara9362 You are mixing up technological advancement and laws of physics. EVs have been efficient from day one due to physics, but lacked in range and charging speed. Both things were fixed by improving the technology. Hydrogen cars will always remain far less efficient than battery electric cars because producing, compressing, transporting and converting hydrogen is paired with a lot of losses. Improvement is possible, but elimination of these steps is not. It's that simple.
1
Because combustion engines are even more inefficient than a fuel cell. Therefore cost per mile will be higher.
1
Because it is VERY inefficient.
1
But emissions will be far higher than EVs
1
Hydrogen doesn't make sense both economically and environmentally.
1
But very inefficient...
1
@Aceman dave CO2 emissions are always higher than an EV.
1
Yes they are.
1
@romansenger2322 Exactly.
1
You are correct.
1
@thebrowns5337 Explain where platinum (and also lithium) comes from for all these hydrogen cars...
