“Now, there are signs of a comeback. A recent survey of more than 900 global automotive executives by consulting firm KPMG found that 52 percent rated hydrogen fuel cell vehicles as a leading industry trend. Japan has announced plans to put 40,000 hydrogen vehicles on the road in the next five years, and South Korea 16,000. Germany wants to have 400 refuelling stations for hydrogen vehicles by 2025 and California has already opened 35.”
Fuel Cells
www.energy.gov/eere/fuelcells...
“Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes-a negative electrode (or anode) and a positive electrode (or cathode)-sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode.”
Toyota plans to expand production, shrink cost of hydrogen fuel cell vehicles

Then if the fumes find an ignition source, you have a difficult to extinguish, long lasting chemical fire. If hydrogen leaks, it quickly rises into the upper atmosphere making the chance of a fire/explosion much less. Lithium battery powered cars are more dangerous than hydrogen. Several Teslas have caught fire. So have many lithium powered hover boards, laptops and smart phones. And these can catch fire just from simply discharging or recharging too fast.

Excellent topic and video! The other big disadvantage of hydrogen fuel cell vehicles is that they’re only around 55% efficient, whereas battery-electric drive trains are around 90% efficient. Also, 400KW battery-charging is starting be deployed, which will get a battery-electric vehicle, typically, a couple-hundred miles in 10-15 minutes. That’s not quite refueling kinds of speeds, but not far off! But most importantly, modern battery-electric vehicles (for most people) almost never need to be quick-charged. Most people can drive a Chevy Bolt a week without having to recharge and many people just charge up at home nightly anyway. As an aside, regarding efficiency, both fuel cells and batteries are considerably more efficient than a pure-gasoline drive train’s typically 20% efficiency. Modern engines do have considerably higher *peak* efficiency (e.g., ~40% on the Prius), but are rarely given the opportunity to run under peak-efficiency conditions.

@mr88cet 5 лет назад

A couple clarification points: Hydrogen fuel cells are more like 65% efficient, not 55%, and the ~90% BEV efficiency is only when you include regenerative braking (recharging the battery with the kinetic energy of the vehicle), which all EVs and hybrids have, of course, and fuel-cell electrics can have with the addition of a small battery. There are many more big inefficiencies in HFCs though, like like the amount of energy required to compress the hydrogen, which is pretty substantial.

No it's not true I don't know particularly about H cars but electric cars produce 300%-500% less emission after 5-7 years already (in summary including all possible emission from manufacturing this electric car). They require significantly less maintenance and consumables. It definitely more green to buy new electric car even if you get part of energy from coal and oil. (In case of more green states you will get less emissions after 2-3 years) No one is saying go and buy electric car. But saying it is worse it is strait up lie. But educate me about H car. I would like to learn about it.

@zodiacfml 5 лет назад

It is greener after a few years of use compared to a ICE conventional car/vehicle. ICE cars are very inefficient in terms for fuel use because of multiple reasons. A huge generator using similar fuel gasoline/diesel is significantly more efficient, producing more power. A green car recovers the cost of owning it versus a conventional car in 3-5 years. That is cost alone and cost can translate into carbon footprint if you simplify it. Most of its parts are recyclable. Batteries from EVs are reusable as battery backups before it gets even recycled. It already looks better than LEAD acid batteries in conventional cars which is low cycle and can't go below 50% charge.

The real question is what the environmental impact of all that water vapor is. Because water vapor is a *really* potent greenhouse gas (part of why global warming is so bad: warmer oceans -> more water vapor -> repeat) and you'd put out a *lot* of it. It might be not too much compared to what gas cars put out but it's definitely worse than electric. Well that was hopefully obvious from the beginning on. Your concern about those rare materials and hard to recycle stuff isn't needed. Gas cars have a _lot_ of disposables needing replacement over the years. It's far, far, far less on the EV side. Buying a new electric car isn't better for the environment than driving your old car (as long as it still works, obviously) or buying a used gas car. But buying an electric when you've already set your mind you need a brand new car is plain bad for the environment. And probably for your wallet, too.

@@mandernachluca3774 Another reason why Hydrogen won't work: using enormous amounts of energy to split water into hydrogen and oxygen is expensive. That's why hydrogen is usually won by a different chemical process from Methane, so they use natural gas. Hydrogen from natural gas will always be cheaper than from water (the thermodynamics are aligned that way) and since natural gas reserves will last for another 200 years at least, this would be the source of hydrogen. You could skip the step of getting hydrogen from methane and just use methane as a fuel instead -> more efficient, WAY easier to store and to refill, less dangerous in all aspects and there already is infrastructure (pipelines) for mehtane in most countries, etc etc... Hydrogen will NEVER work as a fuel source because Methane is superior in all aspects. Doesn't mean Methane is the best solution, electric cars could very well be better.

@@thulyblu5486 As imprectical as battery EVs are. What i am trying to say is that , battery EVs aren't gonna cut it in terms of long range applications. They are well suited as city cars but for everything else they are very impracticle. I suggest hydrogen instead of methan because of the change in energy storage we will see in the next century. As we will shift from fossil fuels to regenerative energy sources, we also most likely will go towards H2 instead of Methan. Now methan (besides the infrastructure) has the huge benefit of being made out of CO2 and H2 (you could basically extract the CO2 out of the atmosphere and use it to produce more fuel) the problem however is that this involves a lot of energy as you can imagine more than straight hydrogen production. Therefor i think that H2 would be the better option since you could always store it in unpressurized metalhydrite tanks (german submarines do) and compress it when needed (for example when storing in a 700 bar pressure tank for hydrogen cars). That would make the whole matter much more feasable but nobody seems to think about metal hydrid tanks, sadly...

The CSIRO in Australia has developed an efficient way to convert hydrogen to and from ammonia. Ammonia is easy to store and transport (similar to water) so it may open up both the hydrogen car market and a new form of better battery for homes/electrical grids. Hydrogen can be produced from any water source so long as there is power available so this should be a great use for excess power in the grid(like sunny days where an excess of solar power is currently produced in many parts of the world).

@andrasbiro3007 5 лет назад

Recharging time is far less important than you think. Mostly because you can charge while you are doing something else. Ideally you charge at home while you are sleeping. If that's not possible, there are still many options, like work, supermarket, etc. In the worst case you visit a public charger one in a week or two, and charge for like an hour, while you can read a book, watch RU-vid, listen to music, or do most thing you would do at home anyway. And if you have a Tesla, there's a big tablet with internet connection right in front of you. On long trips you have to stop for like 20-30 minutes every 200 miles to charge, which isn't really big deal, it's actually good for you. And you can still spend that time usefully, like having lunch, or coffee, or shopping. And in a few years charging will be much faster.

I long ago thought of my own model, which you would fuel with pure water, which it would then electrolyze itself and then burn. Only problem is the reason Hydrogen isn't already used in all engines, it's *_way_* too powerful of an explosion, but you could just inject a _very_ small amount and, though it burns much faster than gasoline, a small amount shouldn't destroy a well engineered engine and would be significantly more cost-effective, efficient, powerful, and clean.

Ok, allow me to correct some things: - This setup would simply waste energy. You need more energy to split H2O than you can gain from H2 combustion or a fuel cell. This is ultimately based on the second law of thermodynamics. - H2 is best used to produce electricity in a fuel cell, as combustion in an ICE is not nearly as efficient. - Explosiveness is not a major problem in current HFCVs.

The problem isn't creating an engine that runs on hydrogen. The problem is storing the hydrogen in quantity and having enough energy density. If you compress it you need heavy tanks to contain it. If you chill it you need insulated tanks to prevent it from boiling off. Plus hydrogen leaks easily and it is very reactive with metal. It's fine for rockets where you load it into the tanks as a cold liquid and burn it all off in about 12 minutes going into orbit. But carrying it around stored in a car that way for several days isn't very practical.

If a high efficiency turbine, or fuel cell could be used as this generator to supplement the energy, than it may be the ideal model. And if Hydrogen doesn't work due to infrastructure concerns, then how about Solid Oxide fuel cells than can essentially use any low-sulfur hydrocarbon fuel. It would be a flexible fuel fuel-cell vehicle.

Highly explosive fuel stations, with hydrogen being harder to store than petrol, put people off. And Hydrogen was originally considered as a replacement for petrol due to it being easy to obtain, compared to other alternatives. But it was not the environment that was the concern back then, (and hydrogen cars have bandied about decades), but concern with the possibility of oil becoming scarce.

@dansanger5340 5 лет назад

Because of conversion losses, hydrogen fuel cells will always be less efficient and hence more costly to run than regular batteries. So, fuel cells will only be used in niche applications where efficiency will be traded for an advantage such as faster charging, higher energy density, etc. Such applications might include shipping, airplanes, or long haul trucks. However, since batteries are getting better every day, the fuel cell niche will always be shrinking.

One sec... so you using electrical energy to split water into H2 and O2 (at a loss obviously) to then turn it back into electrical energy (again with some inefficiency)? And then you're wondering why we don't have more hydrogen cars yet? Seems a pretty big waste of energy and money...

@VVayVVard 5 лет назад

That's one part of the equation. However, hydrogen is more energy-dense (mass-wise) than Li-ion battery charge, which is why the wasted energy in the production phase is offset by the energy efficiency when actually using them in vehicles. This is especially true for long-range (100+ mile range) and heavy vehicles.

Currently, the problem is the weight of Li-ion batteries. This becomes an issue at long ranges (100+ miles for personal cars) and with heavy vehicles, as energy efficiency is more or less inversely proportional to mass. E.g. the lightest hydrogen car with a 300-mile range is ~3x lighter than the lightest BEV with a similar range.

@TheWolfHowling 5 лет назад

Why haven't FCVs taken off? Because Hydrogen kind of sucks as an fuel. First, it's not really a fuel, in the way we usually think of it, but an energy carrier, like charging up a battery. More energy has to be pumped into Hydrogen production than could every be extracted from the H2. And second, H2 isn't a very good energy store, with the total well-to-wheel efficiency of a FCV being somewhere around ~30%. Energy is lost during every conversion, from the AC rectifier and electrolysis, the compression and possibly transport for the H2, to the Fuel Cell, inverter and AC motor. BEVs, by comparison, lose far less between the EVSE, transmission losses, battery efficiency and the powertrain electronics, with a well-to-wheel efficiency in the 70%

@Obscurai 5 лет назад

Indeed, for a science channel Seeker doesn't really get into the crux of the problem that hydrogen's inefficiency contributes to its much higher cost/mile (5x by most estimates). This higher cost is the economics of why no company is willing to invest in the infrastructure to make and distribute hydrogen in scale. Contrast that with the existing generation and distribution of electricity and the known costs. It is simply no contest.

@VVayVVard 5 лет назад

This is not actually true. For one, much electricity is still produced from methane, and in this regard, H2 production is about 50% more energy efficient if you use the steam reformation process. Also, for larger and longer-range vehicles, Li-ion batteries become very heavy. Already at a 300-mile range, the lightest BEV weighs 3x as much as the lightest hydrogen car (the 'Rasa' prototype). As such, hydrogen is much more efficient as an energy carrier for long-range and heavy vehicles, and of course ships and aircraft.

@Obscurai 5 лет назад

@@VVayVVard Agreed. Energy density and refueling convenience are the keys to hydrogen's salvation. The problem is that battery energy density (and not just Li-ion) is currently on an improvement trend. This means that it will be awhile before the benefits of hydrogen will be economically competitive. Still have the problem of creating generation and distribution infrastructure, whereas extensive electrical generation and distribution already exists. I expect that hydrogen will only be viable for long-haul or high weight vehicles. Already there are battery based ferries (albeit short range) and of course all the battery based buses. So the market hydrogen is somewhat limited to other use cases.

@TheWolfHowling 5 лет назад

@@VVayVVard Well, yes, you are correct, nearly a quarter of global electricity generation was fuelled by Methane/Natural Gas, and steam reformation of Methane can be made relatively efficient, such as minimising heat loss for the high temperature chemical reactions. However, if the purpose of H2 vehicles is to cut carbon emissions and ween society off of fossil fuels, using Natural gas as the feedstock will just shift and hide the problem. "Pay no attention to the man behind the curtain". Although, Bio derived Methane, maybe from upgraded biogas, could be used instead of fossil.

@VVayVVard 5 лет назад

@@TheWolfHowling This is true, ultimately H2 production should be powered by solar energy. Concentrating solar energy for thermochemical H2 production as done on a micro-scale at the Hydrosol-2 test plant seems fairly efficient for this purpose, and apparently there has lately been some progress on catalytic splitting too. 'Waste' energy from solar or wind panels could also be used to power electrolysis as well whenever grid electricity wasn't required by consumers.

Hydrogen from electrolysis may have a role in the future of heavy vehicles but not in light duty. Its energy density and ability to come from renewable sources works well for heavy vehicles but the amount of usable energy from well to wheels is low. Batteries are far more efficient users of renewable electricity but their poor energy density limits them to light duty vehicles and frequent stop heavy duty vehicles like buses.

@VVayVVard 5 лет назад

This. Also, hydrogen vehicles are (currently, with Li-ion batteries) more efficient in long-range vehicles. Check out the 'Rasa' by Riversimple for example. It weighs just 580 kg / 1300 lbs, but has a range of 300 miles. EVs that reach this range weigh 3x as much, and thus spend much more energy in use.

@XxMadz007 5 лет назад

They don't work. You are always going to use more energy to make the hydrogen than you will ever get back out when you burn the hydrogen. You often see people doing this in You Tube videos.
