The people in the comments complain about the new technology would have been the same people that complained about the first cars in favour of horse and cart. It's a relativity new technology, give it time.

[@JB-gh1vk]

The issue is that it takes more energy to produce the hydrogen, either through seawater distillation or extraction, than you get out of it when burned. Its an issue with chemistry, not technology. The only way you can get more energy out hydrogen then you put in to get it is if you use the hydrogen as fusion fuel. That in itself however is a technology in the works.

[@RM-iu6mm]

Aidan Doherty I’m not sure what the point of hydrogen is. When electric cars had a tiny range and a long charge time, yes. But now that EVs can charge at 150KW it just doesn’t make sense. I believe it’s quite popular in Japan though, so might be missing something.

1) Cost of production; either by steam reforming or electrolysis of water, that takes energy 2)Cost of storage: hydrogen is a very low density gas, so to store it requires a very large amount of pressure, a large container, a strong container to withstand these pressures, and more energy to provide the cooling for the H2 storage 3) Cost of transportation 4) Low volume production: how many people do you know that drive a hydrogen car?

[@MrPikkoz]

Fast refuelling is the only real advantage of FCEV versus EV , other than that from a determined unit of energy from a source (solar,wind or coal etc ) to the wheels ,a battery EV can run 2.5x the distance compared to a FCEV. For example to produce 4.7Kg of hydrogen required to fill up the Mirai it takes roughly 280Kw that could charge a similary sized and ranged EV multiple times. This is because from the source to the tank FCEV requires more steps with more losses each , just compressing the hydrogen to 700bar takes 13% of the energy and no matter how many improvements the hydrogen creation and distribution chain it has you can't cheat the thermodynamics laws. Also with the price of one hydrogen refuelling station (that has to be installed away from buildings) you could install 500-700 public chargers on the streets that don't require staff and moreover don't explode (like what happened in Norway or U.S.A.) also with fast DC charger nowadays you can charge 180miles in 15minutes , not as fast but bearable.

[@abstractexchange5057]

hydrogen is the only right variant for future. No other variant ! But we are developing approach, which is not exact now. There must be 2 waves for hydrogen : 1/BUILD HYDROGEN PRODUCTION FACTORIES ON SITES OF RENEWABLE ENERGY STATIONS. 2/ CARS NEED TO LOAD HYDROGEN BY EXCHANGE WHOLE COMPRESSED HYDROGEN BALLOONS. We are wrong because we do not firstly build enough hydrogen production factories on sites of renewable energy stations. We are wrong because we are trying to build network of hydrogen loading stations, which are COMPLEX AND EXPENSIVE. We must change our approach. We should use hydrogen as energy storage method for renewable energy stations first. Then we should load hydrogen for cars by changing whole standard compressed hydrogen gas balloons. So It is very simple and not expensive to make the global net of hydrogen supplying stations. Any normal mini markets can be a hydrogen supplying point by storing standard compressed hydrogen gas balloons. We do not have to use liquid hydrogen, which is difficult to collect. But we can use compressed hydrogen gas, which is not so much different in weight by comparison with liquid hydrogen. Hydrogen is the best solution of energy storage for all energy stations now, for example, for nuclear energy stations, for renewable energy stations. Just install ready hydrogen production modules, and install independent hydrogen fuel cell modules in adjacent areas. Use compressed hydrogen gas at first time instead of liquid hydrogen. And the last thing to notice is that, hydrogen is not more dangerous than other gases and petrol. Hydrogen has big energy storage capacity, but when burning hydrogen in accidents, IT DOES NOT CREATE ACOUSTIC DESTRUCTING WAVE TO ENVIRONMENTS. It means that hydrogen burning is less destructive than gasoline burning.

It is happening finally, though more slowly in the UK than other parts of Europe of course. The next 2 years particularly will see major manufacturers coming out with new electric models. Forget hydrogen. I don't know when this was filmed but the content is already dated. Battery electric vehicles (BEVs) are winning through. If I had to put my finger on a moment that could be seen as the turning point, it was when everyone realised that Tesla was going to be able to mass-produce the Model 3. Yes, it's still pricey but it's spurred on not only BMW, Mercedes and Audi but has also got Ford and GM scared :-).

[@timsyoutubechannel9798]

@nousernamenow The problem is that the tech (I assume you mean ICE) hasn't actually worked that well - it's the oil that works well. A litre of oil contains roughly 10kWh of energy. Up to now, manufacturers have had no responsibility for fuelling their creations beyond supplying a fuel tank. They've had it very good for a long time. People like to point out that it's difficult to get the same range in an EV as an ICE car or power a home on solar - yes, that's how energy-dense coal and oil are.

I don't know when this was filmed but the content seems quite dated. Pretty much everyone has now dumped the idea of using hydrogen for cars because it just doesn't work on that scale. It works for trucks, trains, trams, anything large. I think the initial idea with cars was for the oil companies to retain some control over how people get fuel by forcing them back to the pump. Trouble is there are an increasing number of EVs that will do 300 miles or more on a single charge, people can charge those at home and there are rapid charging networks where you can get an 80% in less than half an hour if you're doing a road trip. Also, EVs are getting 140+ mpge versus about 60 mpge for hydrogen. The other problem is creating the hydrogen. Unless it's a by-product of another process or generated using renewable energy, there's no net gain. Anything is better than an ICE (particularly diesel) but hydrogen is going to lose out for cars at least.

[@Gma.parkour]

Filmed within the last month, so none of the information is outdated. 80% in less than half an hour is still a completely different experience to refuelling a car with hydrogen or petrol. The whole point is this is a longer term goal, with the ideal process being that we use excess energy produced by wind/solar when it's not needed in electrolysers, and then use fuel cells to convert it back into something useful. And as you've pointed out, batteries are unlikely to be useful in larger vehicles. It's worth thinking about these more as proof of concept of commercial fuel cell vehicles than things people are that likely to drive: the future is going to be hybrids and different technology solutions for different problems

[@timsyoutubechannel9798]

@@Gma.parkour Thanks for the update. I think the inclusion of the car threw me a bit and I guess most aren't aware of hydrogen tech which is why it seemed old news to me. I quoted 80% in 30 mins for EV rapid charging because that's the current (ha ha) standard. Version 3 of Tesla's supercharging should give me 200 miles in about 20 minutes though I haven't found charging time an issues at all. I accept this is still proof of concept stuff but maintain it's not suited to cars (like diesel-electric only works on a bigger scale). I suggested hydrogen could only be generated viably using renewable energy but you're right that it must also be excess to requirements. I like the democratisation that fuelling with electricity represents and I think most people can be forgiven for being cynical about anything that takes us back to the pump again :-).

what a load of gas

[@tienpg2242]

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

[@sickbailey21]

thats not efficient at all, may as well just use solar to charge typical EV batteries. It takes something like 60% of the usable energy of the hydrogen to create it.

[@alinmustata]

sickbailey21 yes but solar electricity can be free.. the thing is we cannot store it when it is needed during evening, so that’s why hydrogen is good and batteries have a negative impact on the enviroment, producing more electricity from solar isn’t. And also electricity from where is produced untill it reaches your batteries will habe to travel km of wires and even from the plug to your battery it’s eficiency is around 86 percent. So it may not be such a difference after all, but what is matter is solar energy is free and unlimited, lithium isn’t and recycling it is also a different issue. Hydrogen is the future it uses 10 percent worth of batteries than a normal medium range electric car

[@sickbailey21]

@@alinmustata its a massive difference even if just buying the electricity. But if you would buy solar for hydrogen, it makes no sense to not buy it for electricity too. As long as you're not driving huge amounts, solar system will be able to pay for itself if using it just for storing electricity. That 60% loss in efficiency just from creating the hydrogen at home has you beat. You then have to compress it and maybe even keep a backup tank of it at home, this is both expensive and hugely dangerous, this stuff is really explosive. Check out some videos on tanks of hydrogen reacting with air. Other than the environmental impact of mining for battery materials, there are no other pros to hydrogen. After 10 years out of service all of the materials from an EV battery can be recycled though. Changing them out every 5 years for efficiency reasons (not even required with the quality of the tesla chemistry) becomes much more manageable as the technology is quickly becoming mainstream.

If we see some radical advances in battery technology then we will probably see electric jets become mainstream before a hydrogen one.

@@sickbailey21 not sure if you know what you are talking about. Most of the Hydrogen dispensers in the World uses their own renewable energy sources to produce Hydrogen also read about PEMs and Hydrogen Ferries.

[@sickbailey21]

@@Soothsayer210 how many of those are there? and they already produce enough to fuel every plane across the world? It takes something like 90 megawatts of energy just to get a plane in to the air. That doesn't include the energy to go anywhere after take off including ascension either.

@@Soothsayer210 most hydrogen is produced from fossil fuels because its the cheapest way to produce it.

[@Soothsayer210]

@@sickbailey21 but even if we produce H2 using PEM from Natural Gas, isn't it still far more cleaner than Fossil Fuels?

Finally we realise that electric can't and won't be the future

Are you aware that nearly every service stations in the UK have tesla chargers and other electric car chargers? If you had say a tesla now you'd be in a decent spot considering tesla chargers are free and in a lot of places so even long distance is perfectly fine.... Electric cars if they become a standard and improve it can be a good viable option

@@Pleasant_exe They are very I'm inviromentally friendly log term and inconvenient People do like change and we would have to drastically change our mourtor way system to compensate for electric cars if all cars were electric You can fill a car with hydrogen in seconds and the only product is pure water You could drink from your car They don't have expensive batteries that need replacing every decade and are extremely damaging to the environment and uneconomically viable long term due to the extra metals that would have to be mined to use in these batteries There is only so much you can do with batteries in a car no matter how much they progress and they will always die and not take a charge after a while For the moment they may be more convineant than hydrogen but that's only due to politicians being ignorant and seeing it as a green future That money could have and should have been put to the hydrogen industry Your right they are at many service stations but I don't want to stay at a service station and have to wait a long time for my car to charge I don't know anyone who would And you can integrate hydrogen into petrol engines and make them up to 70% more efficient as all the fuel is burnt as the petrol is mixed with hydrogen and less is taken in in the first place and it is really simple to integrate it unlike a hybrid petrol electric People and manufactures would be more happy to improve there current engines to include hydrogen than have to redevelop just to make a hybrid That would slowly lead to a green hydrogen future

If you keep sending hydrogen to it, it will keep generating electricity. So why not make it feed off the atmosphere around it?

I can’t believe people are still attempting to make hydrogen work. Best case hydrogen isn’t as efficient as current case electric - surely you stop there?

[@mjribes]

Hydrogen cars are a really, REALLY bad idea. Why? Because they pump water vapour out of their exhaust. Can you imagine thousands of car in London all pumping out water vapour? Humidity would go through the roof and fog would become a major problem on congested roads
