- čas přidán 29. 06. 2024
- Kyle and Alyssa head out on an experimental road trip in a hydrogen fuel cell Toyota Mirai. This road trip is meant to dip their toes in the water, requiring two fueling stops. While it's not a long distance trip like you're used to seeing on this channel, we thought it would be interesting to share their learnings with you along the way.

I know this video is a bit different and has a lot more conversation about powertrain technologies rather than scenery, but I thought it would be something some of you are interested in! If you like our typical road trip videos, we have plenty more to share with you to come. Thanks for watching!
Heck yeah I'm interested in this!
Thanks for the video.
I agree with you, hydrogen power-trains are destined for things other than passenger cars - trucks? trains? ships? Too many fossil fuels involved. I'd rather just use my solar panels to get myself around ...
Wow. That's wonderfully cheap for a tank of hydrogen. Here in New Zealand, to fill up a Mirai costs just over $500 because it's not taxpayer subsidized. American taxpayers must be pretty awesomely chill to be happy with footing the rest of that bill.
Homebound for awhile, recovering from mild bout of COVID. Love cross country motoring so your OoS Motoring episodes allow me to experience that vicariously! Many thanks to you and Alyssa!
Kyle is the kind of guy to tell Alyssa “wrong answer” when asking her opinion
Yeah, the mansplaining is strong in this one.
yea I noticed that he'll ask her opinion on things then when she answers he's VERY dismissive towards her answer...I don't get it...even when she speaks and asks questions or makes comments his tone changes...weird
@@Uptownlegend85 For sure. In this case, Alyssa made several valid points and he still insisted on contradicting her. On camera. Pretty dysfunctional imo.
@@EirikNewth1 I agree with you.
I’m glad I wasn’t the only that thought this. It turns me away from his videos.
yeah so early FCEVs like the honda clarity had the fuel cell directly connected to the wheels and when you'd accelerate you'd hear the compressed hydrogen being squirted into the fuel cell and the slight lag until it accelerated, like with an ICE vehicle, they added the inline battery for user experience
Nice to see Alyssa infront of the camera again. Interesting format video. If all gas stations had Hydrogen it might be an option.
Amazing video guys. Kyle, like always, giving a lot of good information on this car. Good team work guys.
I have some hands-on experience with compressed natural gas fueling stations, which isn't perfectly analogous (CNG is 3,600 PSI, Hyhdrogen is 10,000 PSI!) but the overall mechanisms are the same;
Regarding the pulsing - What it's doing is trying to calculate how big the tank in your vehicle is. By giving you a shot of known mass and measuring the change in pressure it can calculate the tank capacity. It needs to do this to because the tank will heat up substantially as the pressure increases, and to get an accurate fill you can't rely on pressure readings alone. (It also can detect leaks or improper connections during this phase but that's not the primary purpose.)
Regarding the "three phases" - There are three pressure tanks (or groups of tanks) where the gas is stored. The dispenser will connect your vehicle to the tank that has the lowest pressure that's still above the pressure in your tank. So the dispenser will connect tot he low-bank first until the pressures are almost equal, then switch you to the mid-bank, then finally to high-bank.
This controls the rate of fuel flow (you don't want a >8000 PSI pressure difference!) and also improves utilization of storage. For example, if the high-bank only gets used for the final top-off then it will get depleted less and stay at higher pressure allowing more fills. The low-bank usually has a much larger volume as well though I can't speak for Hydrogen in that regard.
For CNG there may also be a direct fill phase. Since these stations take natural gas from the mains under the street and compress it on site, it's possible to pump the gas directly into the vehicle. This is quite slow of course... I don't know if Hydrogen stations have any on-site compressor equipment to ensure a max fill.
The filling station compresses the hydrogen gas to 1050 bar (15000psi) in it‘s own tank to then have the gas pressure on both sides equalize at the wanted 700 bar (10000psi). It is during this pressure drop that the gas is getting warmer as hydrogen gas - contrary to the CNG you know - gets warmer when expanding. After that process the filling station needs to cool down to -40°C again before it‘s ready for the next customer.
@@karlgunterwunsch1950 Interesting. So I guess a hydrogen station has two tanks and it fills one from the other?
Also I'm not convinced that hydrogen heats up on expansion at these pressures; It does happen but the inversion point is like 150 bar isn't it? All the pressures in this system are way above that, so it seems we'd not see that effect. Illustrative to my point is how the nozzle ices up in both CNG and hydrogen dispensing. Open to be proven wrong though 'cause I have no direct experience with hydrogen dispensing equipment.
Good write up
Alyssas face when Kyle was talking about the hydrogens Pro & cons 😂😂😂.. Was like "I don't care honey" 😂😂😂
Totally, we need some videos of Alyssa reviews Kyle's videos ...
This video reminds me of your very early day videos road tripping EVs.
Great content you two! Love your road trips. ♥
Been waaaaiting for this. Atlast!!
About hydrogen station refilling, there are liquid hydrogen production facilities coming online. Last month, one by Air Liquide in North Las Vegas got online. This facility alone could feed 40,000 FCEVs when it reaches to its full capacity. Many more to come (perhaps in the other states as well if people ask their legislators).
Great video, just a normal day going to see a friend. Demonstrates how easy it is to drive on Hydrogen.
I think that you have a good point. You can’t fill it at home , but for apartment dwellers or city dwellers where you can’t charge at home. It would be great. They really should make a small hydrogen commuter car.
That's the issue with hydrogen though. For it to have any reasonable range, you need A LOT of it. Mirai is a huuuge car, but it's very cramped in the back and has a ridiculously tiny trunk, because it's all tanks. And that still only gives it the same range as a Tesla Model 3 LR...
There's simply nowhere to put the tanks in a small car.
The Mirai is anout as small as possible because it needs big tanks and crash structure surrounding those to prevent hydrogen discharge in the case of an accident…
Nice to see Diversification on the channel!
Thank you for wonderful reviews
That was awesome! I love the hydrogen FCEV tech. I hope Toyota sends you one to Colorado.
I agree, that was awsome. I hate hydrogen FCEV tech, because it is sooooooo inefficient. Takes a lot of electricity to make hydrogen. too much to =ever make it viable for passenger cars
Living in Australia, I drove nearly 1000 km the other day. If every servo had hydrogen pumps this would be perfect for quick refuelling. Petrol pumps didn't sprout out of the ground, infrastructure takes time.
Kyle, I love your videos and I wanted to encourage you and tell you that I am so glad to see you trying to respect Alyssa more. I know that this is a work in progress, but I am very glad to see you warring against your flesh. If one day you are blessed enough to have her for your bride for life then you will need to build that aspect of your relationship (trust me, I've got 37 years with my bride!). Thanks to you both for this video, it was very fun and informative! I do enjoy hearing both your and Alyssa's viewpoints (technical and more personal). Looking forward to another road trip with the dogs!! Blessings to you both!
yea he's a little rough in her when she gives her opinion on anything. he'll ask her opinion then will be very dismissive with her response. I don't get it.
How much does it cost new? $70,000? Fuel is, what, $15/gallon gas equivalent? Can’t take it out of state? Almost like a horse.
Lol that’s why you buy used Maria 2021 for 25k with 33kmiles
With 70k to spend buy a used Tesla falcon 2020 for 60k
Way better buy
Get educated. The base spec is $50,000 and you get a $15,000 card to fill up on hydrogen. I bet you rarely go on road trips anyway, so your worry about going out of state is worthless.
@@toozzzy396Teslas are crap.
@@legacyjeetkunedo492 Get educated. Base trim is a POS. I bet you don’t even know how to drive out of state.
That nav display looks like tomtom !! Interesting concept. Hopefully you got your paws on In and Out “Double Double” mate! The very first thing I do as soon as I land in Cali! You got to! Cheers! 🍻
Charging is a term used with pressurizing hoses, not just charging with electric, so the terminology on the pump could actually be correct 23:20
Just like with EVs...Hydrogen just needs some research and planning but I'll take EVs any day of the week...but I do see this for long distance trucking and buses and what not as you mentioned.
2:01 $69,420 I see what you did there.😉
Nice
Welcome back to San Diego!! You should come by Off Road Warehouse. We have stuff for your Sprinter. Big fan of your Videos
Mirai's hydrogen fuel gage does not include reserve (gas cars have this), which is about 8% of total capacity. In other words, you can drive about 30 mile beyond zero.
Alissa is smart because having a Hydro station at a Gas station doesn't make sense . Hydro-KA-Boom
Hydrogen pushed by Fossil companies as they produce Hydrogen as part of natural gas production - and actually 5 minutes could give you 60 miles in E-GMP cars and many 800V systems and they are getting - and how much did that cost??? How far will it get you? Surely still much more cost to run. Oh and wholly inefficient using 4kWh to make 1kWh of electric charge...
Great video. I looked into this car a few months ago. The Toyota Dealer in San Francisco had 20+ used ones on their lot for under 20k with under 50k miles. Seemed like a good idea at the time until I researched where I could get fuel. There are not that many in the Bay Area and all of the reviews had 2 things in common. The stations were empty or broken, a lot. Not worth it for me. Limited refueling places and unable to leave the state with it is a deal breaker for me. I wouldn't mind getting a EV since I can charge at work for free but new EVs are out of my price range.
Which year is this? And when compared to the mirai 2016-2017-2018-2019, how much more spacious is the driver seat? Is there more leg room? Or the spacing is the same as previous generation?
A few points: fuel cell generate electricity out of hydrogen in the tank and oxygen from air. The small battery works only as a buffer when necessary: acceleration and deceleration. Otherwise fuel cell directly drive motor. Fueling time for EV is most likely limited something similar to now due to charger/grid size constraint, while hydrogen refueling already achieve 5 min to 100% from empty. So, unless you use your car only for commute from home, there will be a big difference in convenience in particular if you live in apartment. It is up to all of us to decide whether we replace gas station with hydrogen fueling station, which will offer the same refueling time. If we are to support EV charging only, everybody will be stuck with long charging time.
Regarding the fueling station performance, old stations could go slow when it was high temperature since hydrogen has to be cooled down to -40C before dispensing. I think newer station does not have this issue (not confirmed).
I like EVs and charging over night at home at $.11 a kWh ✌️😊
In my case free, on account of the solar panels on my roof. They paid themselves off years ago ...
What was the point of this? Lmao
@@Superman-xr1oh I don’t remember it was three months ago. 😊
@@brianmartin3263 🤡
Hydrogen is interesting and has obvious applications, but my god $60 for 280 miles is horrendously expensive compared to an EV! But for long distance, trucks bus etc it makes a lot of sense and I’m all for it!
"...a water snob..." They're the worst!😃
Great video! I think a lot of the criticism directed towards hydrogen fuel cell vehicles also applied to electric vehicles early on, but the market has been able to address them as it has grown. Having to search for recharging stations is a bit of a pain, but hey sometimes gas stations run out too! With a critical mass of users, hydrogen fuel cell vehicles could overcome this and address some of the other issues. Can it do so before EV's take over? Well there's still a lot of ICE vehicles on the road, so there's definitely an opportunity to grow.
Hydrogen power-trains will remain expensive because making hydrogen is energy intensive ... just use the electricity directly instead of converting those joules to hydrogen and back to electricity again.
@@OAK-808 Hydrogen production works well with the intermittent supply of so called renewable electricity generation, because it is expensive to store the peaks and troughs of renewable electricity ( and some days with no electricity production ). So instead of making hay while the sun shines, make hydrogen instead. By the way, after dark in California the grid largely relies of fossil fuels - so those BEV maybe not so green after all. Due to their unreliability ( whim of nature ) every renewable energy generator you need 100% backup from mainly gas turbine generation.
Where did you get your music?
HFCEV don’t scale linearly and that’s a good thing for full size vehicles, however not good for small vehicles not enough volume.

Due to their unreliability ( whim of nature ) every renewable energy generator you need 100% backup from mainly gas turbine generation. In the UK we sometimes go weeks at a time with little solar production, and during the coldest times when a 'high pressure system' sits over the country we get not much wind power either, so we still have to use fossil fuels in gas turbines to make up our electrical supply. From about 30 GW of installed wind I have never seen more than around 19GW going into grid, and with solar, 15 GW installed never seen more than about 8GW on a cloudless day in middle of summer - and during October to March we get little solar for just a few hours a day.
Good info about hydrogen cars. What is the music track used here?
As a fellow "water snob," I understand the intrigue of not knowing what to expect and wanting to try water produced as a by-product of the car. However, I know what to expect from a fridge, and it's gross. There are even certain bottled waters that aren't any good IMO. Looking at you Arrowhead and Crystal Geyser.
It could be a great Uber leased vehicle. If you live near a station.
The cool thing about hydrogen fuel cells is they used them to power the Apollo moon landing vehicles.
Toyota, H2 isn't suitable for consumer cars, it's a lot more viable for commercial fleet. Those major companies can reasonably set up a refueling station locally whereas asking Bev owners to forgo the convenience of home charging is a hard sale. Just saying...
So, the hydrogen stations are not part of the car's navigation system? That's a big drawback.
Until we can use clean nuclear (eg fusion) to split water into H2, I can't see this competing against pure electric.
The issue with Hydrogen Fuel Cells is simply the energy required to produce the Hydrogen makes it not worth it. It is REALLY EXPENSIVE to fuel a Hydrogen powered car.
Almost the same sentiment when batteries were still in their early days. Hydrogen can have the option to be produced with green energy. As the technology advances, it gets cheaper. With hydrogen, we don't need to make a giant hole on earth to mine those precious rare metals used in batteries.
@@elvinbertcorvera1884 Batteries certainly have their issues. However, charging a battery isn’t the same thing as producing the Hydrogen. Producing the Hydrogen is EXTREMELY INEFFICIENT. It not only requires a lot of energy to separate it but it also requires a lot of energy to compress it, transport it, and it isn’t as efficient when you go to use it as an energy source.
@@LearningFast I think it would make more sense for huge things, like trains, boats, and maybe planes. But for something small like a car it doesn't seem to be worthwhile.
He filled it from near empty for $60, that is currently less than I am paying for a full tank in my V6 powered car, and I only get 200 miles between fill-ups, so I have less range too. How is that expensive?
@@DragonfireRC your ICE car is ridiculously expensive too. I pay $0.11 per KWH for electricity at home in NC. That is about $8.70 to fully charge my Tesla Model 3.
San Francisco Bay Area is Silicon Valley, and headquarters to all the world's leading tech companies: AMD, Intel, Apple, Google, Netflix, Facebook, Twitter, Oracle, Tesla, etc etc.
There are only about a 15 hydrogen stations in the entire Bay Area. Some of them are usually off-line. And of course you cannot produce hydrogen at home.
So that is pretty much a TOTAL deal-breaker. You can only drive from Bay Area down to Los Angeles. At all other areas, no hydrogen stations!
How about San Francisco to Colorado? Nope.
How about San Francisco up to Seattle? Nope.
H70M is for the member for TZ stations but TZ has not activated yet.
If your by product is H2O (Water) and it is dumped on the road can you image if this was the power train of choice and it was in an area it get below freezing. How would you keep the roads from ice build up from all the water being expelled from the car?
they actually recommend purge at winter when you park in for the night
It's too bad you didn't bring any GoPros for this road trip, it would have been a lot easier to watch with a wider angle.
16:42 You should have tried a road trip to Las Vegas, it would be more challenging and I'm not sure if you'd make it back since there are no Hydrogen refueling stations in NV.
Nowadays, a near full tank refill for my Jeep Wrangler costs slightly over $70...
Hydrogen doesn't sound much more expensive at all relatively. Might even get more range for the buck.
Try fuelling your EV at home ... so much cheaper then hydrogen or gasoline ...
@@OAK-808 Bold of you to assume I have a suburban home with a car charger.
hyrdrogen will definitely be part of our future, however the adoption to electric trucks is where it will take off. volvo just the other day unveiled their first hydrogen truck that will have a 1000 kilometer range. for it to reach mass appeal the infastructure needs to be cheaper and cleaner. we shall see.
any issues with leg space? There’s that cylinder there
If you think EV charging locations are few and far between. Try looking for Hydrogen filling stations. Here in the Uk we have a total of fifteen. In a country of 70 odd million people and 800 miles by about 300 miles ie not small but 15 in that area is vanishingly rare. In contrast there are over 42 thousand EV charging points. And we all know that isn't nearly enough. That fact alone rules out Hydrogen vehicles. Next the technical issues are massive. Storage, safety etc . Its imo an evolutionary blind alley. The Betamax solution.
I probably see 5~10 fuel cars a day at least in Southern California.
Hydrogen makes perfect sense for heavy goods vehicles. Long distance trucking would require a sizable network to keep it going. Going down to a one car household a PHEV made the best sense for us right now despite having two of UKs limited hydrogen stations within a few miles from home. But we can charge at home. I just wish our PHEV had faster charging for where we are out and about. We also travel a lot and drive rentals more than our own car. We regularly rent EVs if it makes sense. Even when we can't charge where we will stay. I totally understand why you'd chose hydrogen if you can't charge at home!
To me a plug-in hydrogen hybrid would make perfect sense as long as the hydrogen bit can cover about 300 miles of motorway range and the plug-in battery bit can do about 30 miles of range with at least 32A Level2 charging to the battery. On a daily drive I really don't want to have to visit any fuelling station. 20 miles EV range is enough for us in the city with home charging but I do appreciate others need a bit more. But most times I have a rental and stay in the same place more than one night 30 miles from where I stay is more than enough, especially if I have another backup option to cover a few miles.
My experience of renting EV's in Scandinavia is that in the summer high speed EV chargers are far from built out enough. Outside of summer it is wonderful. So to translate that to the rest of the world where most of the population don't take 5 weeks of holidays in the summer (which you probably don't have anyway), you need a huge charging network to support it.
So if the heavy goods traffic will still need hydrogen fuelling stations, to me it would make perfect sense to use the same stations to do short pitstops on road trips or for that matter if you can't charge at home. In between you just stop wherever you feel like. But what do I know...?
Ummm ... scorpions? I'm a-stickin' with Colorado - only fires, floods and drought here, folks. "Nuthin to see here".
Did you calculate what the mpg equivalent is?
Hydrogen makes sense for large commercial vehicles such as 18 wheelers. If they go electric they would need to carry giant heavy batteries.
Classic line from Alyssa: “There’s lots of bubble people out there!”
$82 for 260 miles? That's like 31 cents per mile. Compare that to around 20 cents for gasoline or 10 cents for an EV.
How about Long Beach to SanFrancisco if any station Mirai
I was bigger on hydrogen back when it was being proposed a couple decades ago. Seemed like a good switch to something greener, but looking into how you need to produce the hydrogen and all is really the downside. If you can make it greener and improve the infrastructure, then maybe it has a slight chance of it catching on. I think it's better used for ships and trucks, from what I hear. I could be wrong. I think with the safer and better battery tech coming down the line, EVs will be the leader. I think hydrogen may just be like Beta in the video tape war or HD DVD vs Blu Ray....
For larger trucks and heavy duty applications hydrogen would be way better IMO.
It's kinda like the old AC vs DC argument, or more recently VHS vs Betamax. Hydrogen will loose because it's more expensive to generate and transport than electricity. And the generation of hydrogen causes more pollution than the generation of electricity.
hydrogen has no storage loss and the efficiency is only 5 percent behind. its a secondary storage solution to electric
you should make your Hydrogen Fueling Station available to the public and sell that sweet gravy.
I suspect their only takers in Fort Collins would be commercial users.
I love it when a woman says "my god it's long"
TOYOTA MIRAI 😎👍
I would argue you cannot make the same comparison between this and electric that you would with gas and electric, because I can see some pretty obvious benefits between gas and electric in either direction whereas this car compared to anything only has negatives in my opinion. If the hydrogen fueling process was quicker and less of a headache, then maybe it would have a better argument, but for passenger vehicles, this just makes no sense.
In my opinion, Hydrogen is a good stopgap between fossil fuels and batteries for energy storage for heavy-duty vehicles like Semis, and make's sense to use until EVs can get similar range and charging speed as a hydrogen tank can refuel.
Aside from high-end use cases, Hydrogen is pointless and expensive and.
What people don't realize is that THIS is the future. Toyota was reluctant to build all electric when they knew they found the solution. Governments have put mandates on manufacturers to produce electric vehicles.
That trash can on wheels may be someone living out of their vehicle. Be careful not to judge. I am sure there are folks in Ft. Collins that are similar straits. Just saying.
I guess that I am the only one thinking about the Hindenburg when I hear hydrogen.
How safe is this in an accident where the hydrogen tank is punctured?
I think the big fire from Hindenburg was due to the diesel engines. The hydrogen quickly burnt off in an upwards motion. I may be wrong.
What is the name of your sound track.....
Any station on I-5 S-N please
Toyota just won’t give up flogging this dead dog of a technology for personal transport. Basic physics, they just don’t work
Don't forget that hydrogen is ridiculously expensive too. 🙄
@@justinfowler2857 Yup, because it's very energy intensive ...
Very interesting to learn about hydrogen vehicles.
Please get your glasses temples adjusted so you don't have to poke your glasses back up on your nose.
30% efficient for the power going to the driven wheels compared to 85% plus for an EV seems kind of the wrong answer to having less environmental impact.
Surprisingly it is less environmental impact due to the 100% renewable fuel being carbon neutral. Charging a more efficient BEV will still produce carbon emissions due to electricity not being 100% renewable.
why did it only fill 50%?
It didn't look like there was much rear-seat legroom in that big car.
There isn‘t, the back seat and trunk are compromised by a whopping big 700 bar (10000 psi) hydrogen tank put there because it‘s about the safest place for it in case of an accident.
$80 for 280 miles this is already out the window😂
Agreed. I have over 600 miles on my 2023 Chevrolet Bolt EUV, and haven't spent a penny so far to charge it up. I have utilized free level 2 chargers and a bit of 120v at work. There are two Rivian Waypoint chargers within a 5 minute walk from my front door. Free 11.6 kW charging.
@@unclej3910 it's just a con to get everyone to own an EV then it'll all change and we'll be charged the earth for electricity,just watch.
Funny thing is gas cars can not have gas if the power goes out or even make gas, so I see ev and gas cars are in the same boat
So big on the outside, so small inside Due to the tanks
"what is going on in California?"
Don't mention the war. :D :D
Nice hygdrogen Fool’s cell. So it would cost $82 for a full tank to go 400miles. This cost as much as gas per mile. Then you have the inconvenience of only filling up at 100 stations statewide, maybe only 50 can even fill to 100%? What is the point of this? Buy a car that can only travel in California? This is a clear example of “just because you can, doesn’t mean you should”
2:06 bahahahaha NICE
Technically gas tank is more durable than battery that available to most battery EV
But I believe ppl that buy these car don't care about longevity
Kyle, I wonder if you might have shed a few kgs, or is it me seeing you in portrait instead of landscape!?
Sorry Kyle not Interested, now if you get a chance to do a ride along in a hydrogen truck I'm Interested
Why does that dashboard make me feel like I need a booster seat to drive this car?
Does it have Apple CarPlay 😉.
Yes! And also Android Auto.
Toyotally Pointless! (The car not your review)
Its Expensive to buy, run & maintain.
Hydrogen production, transportation and storage (at 10,000 psi!) are NOT in any way Eco or sustainable.
Hydrogen may come eventually but a BEV is where it is at for the next 10-20 years!
It's just sad after 20 years now, the replacement for the at the time 99-2004 first successful EV's, the hydrogen car, still doesnt really work. For one off trips on low travel days yeah you can kinda work it, I am in many FB groups for these cars, and they can be great but in the end weather its once a month or everyday or months on end, its incredibly hard to fill them up, and its such a limited area you can even take them. Plus they are super expensive to fill on you own dollar, EV's are a better option now, for passenger transportation, its settled, but it is sad that eventually this concept will die.
I see some positive in hydrogen. Superchargers are expansive. 58 cents 19.50 or so a gallon equivalent
That car makes no sense to anyone anywhere else in America.
what type of battery cells are there? It's hard to imagine, that any lithium battery would be able to survive very long in this with such a low capacity . Are those even batteries or supercaps?
I think what could potentially make hydrogen vehicles a future game changer. Would be a possible future breakthrough in technology, allowing the car to actually convert the water it produces back into fuel. I realize at this point its impossible, but eveything is impossible until its not. Right?
"Oh my God, this thing's long." Maybe the first time Alyssa has said that to Kyle...
😂I was thinking that would have been a great "that's what she said" moment
Stay classy, San Diego…
🤣😂🤣
🤣
How old are you, eight?
At this stage of the game. Why use hydrogen, it's only available in California. No where else. Besides they are very expensive. Not something I would get.
As it stands, BEVs are going to be a stop gap measure whilst we wait for the Hydrogen tech matures (specifically the generation that is very inefficient currently) or a breakthrough happens in alternative propulsion tech happens.
@@LordElpme Hydrogen was supposed to be the stopgap until BEV are ready - fuel cells are a mature technology (Apollo 13 happened because a fuel cell failed) that has physical limits imposed by the need to store the hydrogen at high pressures. I have seen a chart in one of the University of Ulm presentations that not only included efficiency figures for current technology but also the theoretical physical limits. There is not a lot of leeway to get much better. And the expenses don‘t stop with the hydrogen, the car is expensive to keep on the road, pressure testing every 6000 miles, new highperformance air filters every 18000 miles, new fuel cell membrane every 36000 miles (and that‘s not cheap at $1600 for the membrane) and a „do not use after MM/DD/YYYY“ sticker on the fuel filler door because then the car needs to be ripped apart and new high pressure tanks need to be installed as the old ones are deemed unsafe to be used.
@@LordElpme uhm, BEVs will be a stop gap to a far more polluting and expensive technology that makes crappy cars with poor acceleration and cargo and passenger space and high costs? Definitely not.
@@LordElpme Just to elaborate a bit on the BEV efficiency - it‘s already at more than 70% with a few more percent to be had on the charging infrastructure and battery manufacture (using renewable energy and eventually recycled materials once the first generation vehicles batteries reach that stage in their life cycle in about 20-30 years). Hydrogen has a theoretical efficiency in the mid 30 percent, as several of the processes do have inevitable exothermic reactions and physical properties of the hydrogen incur inevitable losses. So even today BEV are well beyond the theoretical efficiency of FCEV…
@@tribalypredisposed that is how they are now.. The hydrogen issue is more infrastructure locked that BEV is. Current BEV tech is nothing more than a stop gap till the next breakthrough be it better battery , hydrogen or the next idea.
Sooner or later we are going to run out of Lithium, Cobalt and other compounds we make the cells out of. BEVs will buy us some time, nothing more.
I work with a guy who says one of the benefits of hydrogen is the cost. It costs more than gas!!!!!
Hydrogen can be viable If it can be produce cheaply and 'green'
