Hydrogen Fuel Cells were supposed to save the auto industry from climate change, and promised no harmful emissions from the tailpipe, just pure water. So what happened? Why hasn't the hydrogen car taken over the industry in the years since? And what future does this amazing technology have? Well, it's complicated.

    So I can get a Toyota Mirai with $15000 free fuel for $18000? Basically a $3000 new Toyota hydrogen car? That sounds really good, even with the limitations of fuel that delivers less range per dollar spent and the car being near-useless if you don't live in California or next to a refueling station. But I'd act fast. It seems like these incentives will die out quickly when environmentalist legislators realize electric cars are viable and the same power plants fuel battery electric and hydrogen vehicles, but electric vehicles use half the electricity per mile. Economies of scale could bring hydrogen costs down, but there's no getting around that with current hydrogen electrolysis technology you need to generate double the electricity to move a hydrogen vehicle a mile, compared to the more efficient battery electric vehicles. An electric fleet could be fueled by half the power generation capacity. Fewer power plants. And the cars mostly charge overnight when electricity demand is at it's lowest, which flattens the demand curve the power plants face and increases efficiency and reduces costs even further.

    I disagree, esp with how the hydrogen cars and how they could impact the motor industry, for starters the hydrogen is used to power the fuel cell, which is nothing more than a power generator, it don't serve no purpose other than to produce electricity, the rest of the car, is purely electric, so with the EV Technology like in tesla is very much easily done with similar pricing points in hydrogen cars, their just not as smart as elon to produce such things, not to mention the conveince of filling in minutes instead of hours... if I had to choose between EV or hydrogen, I would go hydrogen hands down, as it solves all the problems (big ones) between EV and petrol cars, like for starters, a long long trip... you would like to be back on the road in mins when you need a refuel/recharge during a very long trip... but with EV's that will take hours, where with hydrogen it'll take minutes same for petrol, but then hydrogen emits no emition's just water making it better than petrol, which is just an overall win in my mind, and theirs so much more than that! it's kinda like a hybrid too, as the fuel cell only kicks in when you are going fast or battery low, as the fuel cell will produce more current than the batter will output, aiding into the performance of the electric motor, which isn't needed at slower speeds so kinda act's like a hybrid in that sense too! So much you had missed in this video... Hydrogen deserve the spotlight over EV's and I think with elon musk's mind set and build a hydrogen tesla.. You could be looking at similar EV pricing with DAMN good performance I can tell you that! The manufactures that are actively making hydrogen cars, don't even have that fast of an EV model themselves anyway I bet their hydrogen cars are faster than their EV's so comparing it to a tesla doesn't rly make sense

    they flopped because they're stupid. electricity can come from renewable resources like solar and wind. hydrogen has to be produced in a factory, then transported by a big rig, then the consumer has to pay upwards of $60 for a full tank, while another person can use solar panels from their home to recharge their EV. its a neat idea but it's not as environmentally friendly nor practical compared to EVs. Hydrogen is not the future.

    this seems like propaganda, hydrogen has an octane rating of over 130 compared to gasoline which tops at 95 and stores more energy than gasoline it also can be mixed with oxygen. performance is not an issue with hydrogen fuel. hydrogen can be ignited and used in combustion engines rather than these electric fuel cells. also producing hydrogen is far less damaging to the environment than producing the same oil thats powering the teslas you are drooling over. there is a reason big oil loves teslas. not even mentioned the facts that lithium batteries such as a energy storage units and you need massive volume of batteries to hold the same energy as gasoline, battery production is also significantly damaging to the planet and the kids that are forced to dig cobalt and other minerals that are used to make these weak energy storage units.

    Mazda, like other companies, experimented with hydrogen on a 93 Miata. This was also done with a Rotary engine which Mazda said was more fit for hydrogen than gasoline. There was also a guy that drove a 1994 Ford Escort on 4oz of water due to him creating a system that created HHO from electrolysis. There has to be some merit to this type of system as Stanley Allen Meyer created a such system that defied the Law of Conservation of Energy.

      @Michael Hines I thought having an EV would be huge adjustment for me. It was a paradigm shift and like all unknowns it was scary. I had range anxiety, especially since I got the standard range in Australia where my family is scattered rurally. But the longer I had it the less anxiety I had. I learnt to manage my range, I learnt to tell if I would need a charge or not. I learnt how to find chargers and manage that when it arose. Which I rarely did. I drive an hour each way for work and I don’t even get close to using even 40% of my range. 400km is a very long way. It doesn’t seem it but in practice it is. I was scared because I was comparing to my combustion car. I’d often need to refuel at the beginning of trips. Or half way through but that was because I’d rarely start with a full tank. But with charging from home. I always start with a full tank. And when I visit family I just plug into their outlet and let their solar top me up when they’re too far away. I have a standard range model 3 and I’ve not felt like I was limited any more than when I had a Subaru Impreza.

      @Michael Hines I believe EV’s can compete. They’re just a different paradigm. Instead of getting fuel at service stations. You do it from home. As you plot a navigation in the car if it’s more than a 3-4 hour drive it automatically detours you to a charger, which in itself is a different paradigm. You don’t have to stand there holding the plug. You don’t have to go up to a counter to pay. You plug in. Either play games or Netflix in the car or you walk to the cafe next door and by the time your coffee is served you’re charged up and ready to finish the trip.

      HHO systems don’t work. Stanley Myers system didn’t work. Despite signing a contract agreeing to it, he resisted giving his car for review to a panel of independent Engineers’s and scientists until his death. After which they got the car and concluded that it didn’t have any net benefit. He wasn’t running on water. He was burning gasoline. He injected small amounts of water creating what was effectively a water injected motor. Which isn’t groundbreaking or even new. WW2 aircraft to temporarily boost engine power so they could take off with extra bombs. Or for the P150’s extra fuel. It didn’t use hydrogen. It just used water.

      but spitting out 3-4 times more emissions in electricity alone to produce the fuel. It then has to be trucked via a diesel truck to fuel stations. Also the water coming out the back is problem for places with climates that can reach below freezing in the winter as it will continually and drastically add to the occurrence and prevalence of black ice.

    EVs convert 80% of the electrical energy from *the grid* to power at the wheels. In hydrogen you've deducted the entire supply chain. I don't think that burning coal that goes into the grid is 100% energy efficient. When you deduct environmental damage when mining enormous amounts of lithium that goes into the huge EV battery it's definitely not twice as efficient overall.

      @gracz misiek it’s my writing style get used to it. As for the other points you claim are unrelated. No. 2/3 hydrogen models dont have folding seats. Why is that relevant? Because there wasn’t the room to do so. Because hydrogens volumetric energy density is a big factor. They could do it in an SUV variant only. And even then, by sacrificing a lot of the boot space. They had a much larger car but only were able to add an extra 0.7kg of fuel and even then, only to get around the same distance. This is to highlight how unsuitable hydrogen is for cars. Why does the transmission matter. Because it takes up space. Hydrogen itself takes up a huge amount of space but to try and fit a heavy duty 6 speed transmission in there too will take up even more space. “No regenerative brakes in one model but not others” there are only 2 hydrogen trucks on the road today. The Hyundai Xcient and Hyzon truck presuming they actually live up to their end of the deal. Both of which don’t have regenerative brakes. Which is only some of the very little info we know about their trucks because they haven’t made any yet other than a few busses and vans. Why is regenerative braking relevant, because you’re obsessed with particle emissions. Of which hydrogen emits as much if not more of than BEV’s both in operation and in fuel production and distribution.

Now you're bringing unrelated transmission stuff just like before backseats that are not folding in certain model but not others, then again no regenerative brakes in one model but not others.

      @gracz misiek probably worth mentioning that whilst the Tesla Semi is single speed and does not require a transmission, the Xcient, ontop of the 980L it needs and the wasted space around the tanks, also needs to fit in a 6 speed transmission to deal with its inadequate power production. So again, even MORE wasted space. also it does not have regenerative braking like the tesla which means, more particle emissions.

      @gracz misiek in what way are they not viable for mass production? Something you've continually failed to answer. All you say is "they wont work" but they do work. as for particulate emissoins. You seem to think Hydrogen doesnt emit particulate emissoins? Need I remind you that hydrogen cars weigh around the same as BEV's? Meaning similar particulate emissions. Further to that because hydrogen car batteries are so small and they are required for the fuel cell, that they cannot utiilize as much regenerative braking meaning they actually put out *MORE* particulate emissions than BEV's do. And whilst they do take up some air, its nothing compared to the pollution they cause by the create of every miles worth of hydrogen. As for BEV's their footprint is much less. thats because whilst they do produce alot more emissions to create a battery, their overall footprint over their life time is less. Because a battery will outlive 2-3 hydrogen cars. and a battery itself does not produce more emssions than it does to manufacture an entire car and then dispose of it multiple times. ontop of that hydrogen request at the minimum 3-4 times as much electricity from the same grid to operate per mile. PLUS needing to transport the fuel on the back of diesel trucks. So they're polluting at *LEAST* 3-4 times as much per mile than a BEV does over its operational life which again, makes them less friendly than BEV's. Sorry but just because one component is emissions heavy to produce once off, does not mean that the whole car over its entire lifespan is less green. Perhaps try looking at the big picture. The Xcient fuel cell truck carries around 32kg of fuel. Which requires 850L of fuel tank storage But thats for 400 miles. To get the same range as the Tesla Semi, you'd have to add another 210L of fuel tanks ontop of that bringing it to 1,060L of fuel tanks (not 500L). It also requires 75 kWh of batteries, which takes up 53L of space. It then carries not 1 but 2 95 kW fuel cells. Typical volumetric requirements of a fuel cell today is around 2.5 kW/L which requires 38L of space each or 76L combined. SO in total the power train for the Xcient will be at best 980L vs a Tesla Semi's 1,000 kWh battery pack which will take up 710L. But if we want the same range as the Tesla to make things fair, the Xcient would require a total of 1,190L. Thats not even getting into the practical wasted space of the fuel tanks (imagine the wasted space when you put a circle inside a square for example.) which means you have to waste even MORE volume than your 980L. The take away from that is that, is that you cant keep scaling before you need to make things bigger. You can only just fit the 1.6kWh battery pack into the Mirari. You cant even fit enough fuel cells into the Xcient truck to reach freeway speeds. its not scalable just because the fuel is light weight.

      @geeeforce water is 2 parts hydrogen one part oxygen. when you split water you end up with 2 hydrogen atoms and 1 oxygen. When you combine hydrogen back into water you need 2 parts hydrogen and 1 part oxygen. There is no escaping that. Which means that whether you keep the oxygen created when you make hydrogen. or you vent the oxygen and pick up new oxygen from the air, makes no difference. Definitely makes no difference to the energy created or required to make hydrogen or make water. its still an incredibly stupid idea.

      You mean the 800 mile run? Well unfortunately it was doing something called “hypermileing” they did a similar stunt in France with the mirai except they got 1,005 km instead of 1,300 km. But notice how they release absolutely no information in which you could work out the average speed. For the 1,000 km trip they did in France they told you the start time and Toyota’s video accidentally reordered footage which had the time in the background when it finished. They were averaging around 45km/h which is 28 mph, in order to stretch the range of the vehicle that far. I’d imagine they went even slower in this scenario to get an extra 300km.

      @I eat Grass incentives don’t last forever. If you’re in a state with Those kinds of incentives you’re lucky. But for everyone else hydrogen cars cost more than a similar sized BEV. Costs significantly more to run, don’t last nearly as long, and have worse practicality. Modern BEV’s even cheap ones have ranges not that dissimilar to a similarly sized hydrogen vehicle because hydrogen takes up so much volume it can’t actually fit any more to go further. The only reason hydrogen is remotely competitive in is because of fairly extreme incentives in very specific states.

      @Engineering the weird guy obviously an EV is going to be a better option if you have cash, I have a friend who owned the 2018 mirai for about 3 years and in the end it didn’t cost him much and he was able to sell and get away with having a brand new car for 3 years for a couple of thousand. Now he is on the 2021 Mirai and he got a good deal too if you calculate how much your gonna spend on the car for 5 years it’s about 2,000 (there’s ofc insurance but that’s a constant cost for every cost so you don’t need to include that) Who cares if the car doesn’t last that long if your just gonna use it for a few years and dump it when you fuel credit runs out in a few years Your not getting me, it’s not about the car, it’s about getting a brand new vehicle for dirt cheap, and if you are a college student ( which is what my friend is) then the cabin space is not an issue. You are litterally getting a brand new car for dirt cheap for 2-5 years depending on how much you use it. Then who knows maybe in five years hydrogen cars become more valuable and you can sell it for a profit. So if you spent 2,000 on it’s cost and sell it for 7,000 4 years later then that’s a cost that will cover insurance and leave you in profit. The government is literally paying you to get these cars. You don’t look at it as a buying a car for longevity, you look at it as leasing a car for dirt cheap for a couple of years then dump it cuz hydrogen costs a lot with the credit. Don’t forget, EVs have shitty range unless you buy the higher range models which cost a ton for a student or the average person

      @I eat Grass you can pick up some pretty hefty savings on an BEV too. But it says something if you have to provide $15,000 worth of free fuel. Once that’s up you’re paying 20x as much for fuel than a BEV does for electricity. Hydrogen is also less green and significantly slower. Ontop of that, whilst hydrogen has very high gravimetric energy density (kWh/kg) it has very low volumetric energy density (kWh/kg) in practice coming out at less than half that of a BEV. Meaning you get sub standard cabin space, the mirai has so little cabin space for passengers they have a cut in, in the roof to create the legal minimum headspace, it’s also so small it can’t actually fold the rear seats to extend the boot which is a shame because the boot on a Mirai, despite being a mid-sized sedan, has a boot almost 100L smaller than that of a Toyota Yaris half it size. BEV’s are known for having extraordinarily generous cabin and cargo space. Ontop of all that hydrogen cars have very short lives. About half that of a BEV if it’s very lucky. They even come off the assembly line with an expiration date printed on them.

Literally you can get an amazing deal for a hydrogen where you end up only paying 3,000 for a brand new car. It comes with big rebates and government rebates where a 50,000$ hydrogen becomes 18,000 with all the rebate and cash benefits plus you get free hydrogen gas for years. So hydrogen cars are great because of the benefits it comes with

      @roy rolson they won’t be used for aircraft for 2 reasons. 1.) power and 2.) volume. 1.) hydrogen has a very low power output. That’s why hydrogen cars are so slow. And why hydrogen needs battery storage of some kind to get enough power to adequately accelerate. They barely provide enough power for cars they definitely don’t provide enough power for aircraft. Hyundai’s hydrogen truck can’t even reach freeway speeds without load because it simply cannot get the power. 2.) whilst hydrogen has extremely high *gravimetric* energy density kWh/kg. It has rather pathetic *volumetric* energy density (kWh/L). In practice it is well a truely less than half that of batteries. So whilst the power train in hydrogen cars don’t weigh very much, they take up *alot* of space. So sure the cars can carry more fuel based on weight and so could aircraft but they don’t physically have the space for it. That’s why hydrogen cars, despite having substandard boot and cabin space, still only get about as far as equivalent sized BEV’s. If we’re talking semi trucks, hydrogen gets less range. And it gets worse as power demands increase and more and more space is taken up by adding fuel cells and batteries to meet operational power requirements and that space has to be chewed up by fuel capacity.

      Because the reality of owning one compared to a BEV is bleak. They’re not even as green as BEV and cost 20x more to operate but they last less than half as long as BEV’s. You noted that Toyota are still making hydrogen cars. They still only making the one hydrogen car model. Just 1. Since 2014. With no significant improvements over that time. But still just the *one* model. However recently Toyota has announced around 30 new BEV models to hit the market, with another 20 planned for 2025. There are over a hundred BEV models on the market at the moment and only 3 hydrogen cars in the market. They flopped.

I'm unsure if aviation would be keen to go to Hydrogen, but electric and other technologies are being explored to replace aviation fuel, which includes things like scramjets and other things. But that will be a ways off. Replacement for diesel on container and tanker shipping will be another key area that is likely getting a lot of research I'm sure.

    I think electric cars are going to hit a wall when it comes to lower income and working class drivers. There are millions of drivers in America who don't have their own garage or carport to charge their car in, and having to spend an hour charging it outside a Walgreens or Starbucks or something a couple times a week is not going to work for them. Despite being less efficient, the range and the convenience of filling up in a few minutes like a gas or diesel vehicle will be very appealing to apartment dwellers, and with solar and nuclear powering the production of hydrogen fuel, there won't necessarily be lots of emissions anyway. I also don't see any reason why they couldn't make a "hybrid" fuel cell vehicle that has fuel cells and battery banks that can plug in as well as charge with regenerative braking. It would actually make more sense and be more efficient than gasoline electric hybrids.

      @Engineering the weird guy you are absolutely right. Agree 👍 on all the points. But, here's the thing. All you said , and the guy in the video explained, is current scenario of Hydrogen. What I am betting on is that in coming 10 years this scenario is gonna change drastically enough to make Green Hydrogen (generated using solar and wind, not even considering the hydrocarbons as is today) most economical fuel ever. I do believe Green Hydrogen cost will come down to $2 to $1 per kg, from today's price of over $200. Couple of serious companies ( who built >100GW solar parks in last 5 years, who provide unlimited data at fastest speed for $2 a month, these kind of things you cannot see here in west) are working on this in India and I do believe their claims, based on their historical achievements, and also I do think I know what's possible and what's not in India. Further, geo-politics has become kind of existential threat to India , and hence self-reliance in fuel has become national goal with govt going all in. Assuming current Indian govt retains power for next term (more than likely) , it will create a market of billion plus Hydrogen fuel users. Includes vehicles, heating, commercial etc. Economy of scale is the key to tip the scale for hydrogen (along with organic technology improvements) w.r.t cost. There are handful of markets in the world which can give economies of scale, and India will be in top 2 , in 10 years. More than 50 billion dollars are invested on this specific goal in India, which obviously doesn't come up in any western media (don't want to go there on 'Why'). Indian consumers, mostly middle income , will remain value conscious and will continue choosing lower cost over high gas and EV cost in India. Both hydrocarbon and BEV are very costly in India, because all of it is imported. This is something you cannot experience here in west where both are comparitively very cheap, and per capita income itself is high. Everyone knows, Indian car makers are losers in ICE to west and Japanese, and lost the race for BEV to Chinese. There is no coming back on both these fronts, and I know they have taken hydrogen race as a primary ambition. Last 30 years none of these Indian players (energy generators or vehicle manufacturers) had home market to strengthen themselves, unlike west, Japan, and recently China. But that is changing in India now, with solid middle class market rivaling China as it is today. With protectionism taking over countries ( which is unavoidable from now on IMO), they will have ample room to strengthen tech and bring down cost selling to vast Indian market. BTW here's the great NYT making a case in 2010, that the Solar power is not economically viable www.nytimes.com/2010/03/09/business/energy-environment/09solar.html . Now in 2020, every new investment is in Solar (some portion goes to Wind too).

      @Vinay No, I mean that hydrogen cars offer very little advantages over Battery Electrics and significant disadvantages. As a quick summary, BEV's have better performance, practicality, convenience, cheaper operational cost, longer lifespan, better safety and they're more green than hydrogen. Hydrogens single advantage is this.. if you drive for a very long trip, you can save 15 minutes filling up. But you wont get extra range, and whilst you save 15 minutes, BEV save 16-17 hours per year as they dont need fuel stations. They can charge from home overnight while you're asleep.

      @Scott Robinson as it stands, unless you're driving more than 4 hours in a single day, you dont need to spend even 5 minutes at a fuel station filling up. You plug into your house when you get home. Even a slow charge will fill you up overnight since you're not charging the full capacity, only your daily commute that you use. So you wake up every morning with full range. No driving to fuel stations, not standing outside with a pump. This saves the average person 16-17 hours per year. which is significant. if you do travel more than 4 hours in a day you likely will only do so once a year or less (statistically speaking). In which case a 20 minute stop at a super charger is enough to fully charge and the new V3's are 5-10 minutes depending on the model car you have. I would say we're already there.

      the problem is the material and explosive potential. a small hydrogen fuel plant exploded in Norway and thankfully no one was at the station at the time. It below away the blast shielding like it was leaf in a hurricane. Secondly Hydrogen atoms are so small they can leak through solid metal yet alone flexible hoses or gaskets. Further to that as hydrogen comes into contact with metal it slowly begins to embrittle it making it weaker. The only way around this is to cryogenically liquify the hydrogen which means you need compressors and a way of extreme cooling the tanks. all in all, it a tall order.

    You're missing two other big factors. Hydrogen cars rely on the pressure of the tank so while there may still be hydrogen in the tank if it's below pressure then you're "out of gas". Second and most important Hydrogen is mostly scavenged from fossil fuel refinement not electrolysis. Even if it was from electrolysis 80% of the electric grid is powered by coal plants that don't pass their emissions standards so it's still a dirty way to get fuel. Plus you assumed 100% efficiency of the coal plants when compared to gasoline cars but like I said the electric grid is horrible so you have to factor that into hydrogen production making it way worse than modern fuel efficient cars. -source: I drove a hydrogen powered bus for two years and did all the research to understand what I was working with.

    Hydrogen doesn't need to 'rule the road' to be viable. I think we need to break away from the idea of a silver bullet energy source. There is no 'one energy source to fuel them all'. The future will be like the present, a patchwork of various energy types to do various things. Each type has it's pros and cons that make them work or not work in certain areas. Mechanics still use air tools in garages. Welders use different types of welding depending on the metal or even the environment they are doing their work. Small tools like drill are electric but sometimes they are AC (corded), sometimes DC (battery). An apartment in a big city might be best heated by electricity from some mega plant, but a cabin in the woods will be best off with a wood burning stove. Hydrogen is great for forklifts and other vehicles that are indoors because they don't produce noxious fumes. It might also be a good idea for underground subways, especially in areas where hydrogen refueling is readily available, or where they can stored large enough quantities of it on site so that they don't need daily refueling from outside sources. Hydrogen production might also be a great thing to do with left over energy from powerplants during usage lulls, such as the middle of the night. Batteries are not great for energy storage. Running hydrogen production facilities at night can help 'store' the energy from plants that can't simply turn off and on at a moment's notice.

You can't just add a tank and fill pump to an existing station for less - like they've been doing for E85 and battery charging? The efficiency may be identical to gas but isn't that a GOOD thing?

      um. no. not quite that simple. Even the most fuel efficient fuel cells use around 3-4 times as much grid electricity to create 1 miles worth of hydrogen than if you had just put that electricity into a BEV. That means if you had 1 wind farm to power the needs to 1,000 people with BEV's, with all the tax payer cost, emissions and materials required to build and operate it, you would need 3-4 wind farms to power the needs of those same 1,000 people with hydrogen. additionally no, you wont get similar ranges. the efficiency is there sure, but the fuel isnt. Everyone says hydrogen is very energy dense. What they mean is its gravimetrically energy dense (kWh/kg), but hydrogen practically is not very *Volumetrically* energy dense (kWh/L). With batteries well more than double the volumetric energy density. What that means is you dont really have the space to physically put the fuel to go as far as an ICE. whilst hydrogen cars in most cases get only about as far as their equivalent BEV's competitors, even when sacrificing cabin and boot space to do so, and in some cases, they get less. (hydrogen truck the Xcient for example gets 400 miles fully loaded whilst the Tesla Semi gets 500 miles fully loaded.) Just look at the model 3 vs the toyota Mirai, Both are in the mid-sized sedan class, the Mirai being a little longer than the model 3 but otherwise being near identical in size. Despite this extra length, the Mirai has a boot size almost 100L smaller than that of a Toyota Yaris *half its size* and has so little cabin space you cant even fold the rear passenger seats to extend your abnormally small boot, all to fit 150L of hydrogen tanks (more fuel tank capacity than a ford F150) to get 400 miles. The model 3 gets 325 miles (only 75 miles less) to a charge, but it not only has a huge rear boot with a second large boot compartment inside the rear boot but also has a front boot. It also has class leading cabin space and the rear seats do fold. The Mirai is efficient for a hydrogen car using its fuel cell. Less efficient hydrogen cars will either get less range or have less space for people and cargo. Combustion hydrogen is less efficient again. (Fuels cells are roughly 45-60% efficient, combustion hydrogen is 20-25% efficient), meaning they get even less range.

      it could. yes. But it wont make a big impact. Even on a BEV which can get significantly further on the same amount of energy cannot extend its range very far with solar mounter to the roof of the car. A car typically has between 1.5-2 m2 of roof area, as you need to use some of that for front and rear windows you get around 0.5-1m2 of available roof area in which you could mount solar panels. as a general rule of thumb, solar panels produce 1kW per m2. so best case you'd be getting 1kW peak during a sunny mid-day. I can do the maths for you if you want but for a long range model 3, driving an average speed of 47mph, (75km/h) you'd get an extra 41 miles (66km) bring your range from 325 miles to 366 miles. (around a 13% increase in range assuming a perfectly sunny day and a noon sun lasting more than 8 hours). for a standard range model 3, you'd only gain an extra 28 miles (45km) which is a 11% increase in range. Considering mid-day sun doesn't last 5-8 hours, we'll assume the standard solar utility factor of 30%. So you'd actually only gain 4% for the long range and 3% for the standard range. Now if we look at hydrogen, like the Mirai, uses 5.6kg to get 400 miles. (0.014 kg/mile). Hydrogen has an energy density of 33.6kWh/kg so it uses 0.47 kWh/mile. We know that producing hydrogen is at best around 70% efficient. We also know it needs to be compressed which is at best 85% efficient. Meaning only 59.5% of the energy ends up as hydrogen. so our 1kW becomes 0.595 kW, plus out 30% utilisation factor, making it 0.18 kW from solar into hydrogen. What this means is that we can only boost our range by 4.6 miles (1.1% increase). It does increase efficiency and range, but not by alot, especially for hydrogen. 3-4% for BEV's and 1% for hydrogen.

    Here's another one with respect to convenience, I spend around 10 seconds a day charging my Tesla in my garage, 5 seconds to plug in at night, and 5 seconds to unplug in the morning. I never have to travel to a gas station and wait in line. Usually, the time supercharging isn't wasted either since often there are places to eat and whatnot within a short walking distance. As for efficiency, a Prius is not far behind the Marai when it comes to efficiency. One other aspect is that today most hydrogen comes from reformulating methane, a 70% efficient process that outputs CO2.

    Hydrogen make be more viable in Capitalism than the current model for electric cars, Those industries responsible for gasoline aren't going to disappear without a fight and Hydrogen could be a viable transition for these industries as far as infrastructure and workforce are concerned. Pure electricity without something like a power cell that you replace at "fill-ups" will likely get lobbied out of the US unless someone like Elon Musk supports it.

      Because it’s even less efficient than fuel cells. And sorry no, converting an old car to hydrogen would only work for a little while before it destroys the engine. Hydrogen embrittles metal it comes into contact with and increases wear

    The thing that blows my mind is no one discusses EMF frequencies. I'd rather have a green car not constantly emitting radiation while i drive. It's bad enough we have Wi-Fi and Bluetooth already.

      The cars themselves are shielded. There is less emf in the vehicle than you get from standing outside in a field. Additionally the same emf output would be found in hydrogen as it too is electric. Further more there have been comprehensive studies on emf. It has no affect of your cell function at all. Otherwise the device called a mobile phone, which you keep in your pocket, hand or next to your face 24/7 which emits some 400 times more EMF than an EV does, would have done more damage by now.

    On convenience, EVs suffer from a major refuelling problem. It takes so much longer than either hydrogen-fuelled or fossil-fuelled vehicles to recharge an EV. Also, if you run out of charge on the road, how do you take a 10 Gallon or 10 Litre container and "refill your EV battery"? Hydrogen and LPG have the same problem but don't have the time at the bowser problem.

      EV’s can be charged from a small portable generator. Which helps. However I wouldn’t say EV’s suffer from a lack of fueling problem, more than hydrogen suffers from a fuelling problem. To explain, very few people have a daily commute more than 75 miles, hell even on a busy day you’d be stretched to even travel 100 miles or so, meanwhile modern EV’s have a range of 300-400 miles. More than enough for daily activities. Meaning you can charge from home while you’re asleep and not using it. Full range every day. This saves the average person between 16-17 hours a year from chasing fuel. Hydrogen, you have to find fuel stations to fill up, even if there were stations around. If you have spontaneous things to do, you might find yourself looking for a fuel station, whilst EV’s have full range at the beginning of every day. The only time a person might spend more than 4-5 hours of driving in a single day is for the rare long trips most people do *less than once a year.* wasting 16-17 hours per year only to save 20-30 minutes of charging on a trip you *might* do once per year or less doesn’t make sense:

    Hydrogen is better than electric ! While a hydrogen car needs 3 minutes to refill a electric one needs 12 hours ! A hydrogen tank has 87 kg, while a electric battery has 500 kilograms ! It's not rentable to make electric batteries for monster vehicles like airplanes, ships, tanks, trucks, etc ! And it's better to urinate water (as making water is how it obtains energy) rather than FART toxic gases ! Tesla is a weak car design, making a vehicle being reliant on a bettery is the most inefficient thing you could make ! Like most of Elon Musk's ideas, Tesla cars are more known because people are more clueless, know almost nothing about science and judge things by popularity , not efficiency.

      Tesla isn’t a weak design, hydrogen is a weak design. I can’t see a single reason to get hydrogen over a BEV. They get similar ranges, but hydrogen cost 20x as much per mile for fuel than a BEV, significantly less storage and cabin space than a BEV, significantly slower than a BEV, you have to waste time going to a fuel station, less crumple zones than a BEV making hydrogen less safe, shorter lifespan than a BEV. Less green than a BEV. And even if you wanted to do a long road trip where you can take advantage of the fast refuelling. You can’t, because there isn’t anywhere to get the fuel from. In what way exactly is hydrogen better than battery?

    • Engineering the weird guy

      Engineering the weird guy

      18 days ago

      Actually even the most efficient way to produce hydrogen requires hydrogen 3-4 times more electricity per miles worth of hydrogen than a BEV does, and it doesn’t take 12 hours it takes 4-5 hours, whilst your asleep, at home, meaning time wasted is 0 hours. Meanwhile if you have to find a fuel station once per week that’s 16-17 hours per year down the drain. Hydrogen is more energy dense yes, but volumetrically (kWh/L instead of kWh/kg) not so much, taking up more than twice the volume of a battery for the same range. That makes hydrogen cars impractical as they have smaller boots than cars half their size and cramped cabin spaces. They’re also significantly slower and last less than half the lifespan of the battery with hydrogen cars coming off the assembly line with expiration dates printed on the fuel caps. Ironically the longest living part of a hydrogen car is the battery.

    ICE vehicles will realistically never be renewable. Every process that it takes to create hydrogen can be renewable. Hydrogen cars are not likely to be as convenient as electric cars anytime soon. Essentially everyone has access to electricity. Access to hydrogen makes it, at best, as convenient as gasoline. We'll see what time brings, but I would like to see a hybrid hydrogen/electric vehicle. Traditional plug-in for most people's day to day and optional hydrogen to recharge the battery on longer trips. Everything would essentially work the same as an EV today, only with the option of using hydrogen to 'refuel' the battery vs only traditional electricity. Improving the convenience of longer trips.
