Need to compare total lifecycle cost i.e. cost of replacing expensive lithium batteries, difficult to recycle used batteries, declining efficiency of batteries, loss of economic usage during long recharging battery replacement, etc. Most comparisons are flawed as they compare just core efficiencies.
At minute 2:00 there is a content error. All electric motors used for cars, trolleybuses, locomotives, submarines, etc. they run on direct current only. Only the direct current electric motor has the maximum rotation moment at minimum speed and for this reason it is the best for such applications. If the direct current generated by the hydrogen cell is transformed into alternating current, then the reason is different... Probably the voltage must be raised, stabilized or in general, energy management depending on the operating regime requires its transformation... In my opinion, it is there must be an energy buffer with supercapacitors or something similar...
I did the math myself, fuelcell car has 49-54% efficiency after electrolysis and compression (I compress mine off of external green energy). Whereas a battery has voltage losses along a wire (which the h2 gas doesn't have when traveling to the fuel cell under 10k psi). Process H2: - Green Turbine power 100% - Electrolysis, 72% - Compression - 5%, but for my sake I just made an extra turbine setup to power it so 67%. H2 to H20 Fuel Cell 48-50% efficient The big lie revealed, Battery Process: - Green energy 100% - ~5% from heat/voltage drop to 95% - Funny enough, dc current makes electrolysis equivalent process store electrons on the plates of cathode and in o2 gas (very low energy density compared to compressed h2). -77% resulting from battery charging. - Voltage drop to electric motor -5%, 72% total - Electrical motor prior to trans (75% efficiency), 54% total. - Transmission -5% for torque conversion loss, total remaining power 49% Yes this is comparable to a fuel cell car, but think! A battery like this is new, after 2-3 years a well maintained battery will lose 1/5 and roughly have 39% total energy. Whereas h2 tanks much like your gas tank doesn't change its capacity whereas a battery has corrosion on its surface plates = less capacity. Further Cons of EV's: - Must trickle charge constantly, h2 doesn't leak below 700bar. - Letting battery charge drop below 60% has damaging effects as well as rapid charging it. Consequentially, a gas or h2 car has no effect on long time performance when driving close to Empty 😂😂😂 - The average users driving and maintenance habits will trash most EV batteries, Tesla included in 5-6 years (they claim 10 year warranty yet have a policy that excludes outdoor vehicles, constantly rapid charged vehicles, and etc.) So for a couple dollar electrodes every month, I myself would prefer to you my wind power to make roughly 1lbs a day @ 3kw or in easier language terms 50miles of potential fuel a day. Sad part is to charge a 160kwh EV is that on a fast charge it cost ~$45, as opposed to a gas sedan as of 09/24/22 only $38.70 @ 10gal. Best part is your H2 is free after about $1k investment into homemade wind/solar setup (solar probably closer to $2000ish). A pro of H2 in comparison is that you can fill tanks while your away/ vehicle isn't home and they're easy to swap out the back of a vehicle in lower volumes or to make your or pressure release valve to fill an internal tank or a refill valve on the vehicle.
We have hydrogen powered forklifts at my Distribution center and they are very neat. We used to have battery powered lift but these hydrogen powered forklift cells are much more efficient and seem to be more reliable.
The Eco-Runner XIII recently set a new record by running 1546.18 miles on 950 grams of hydrogen. That's 0.61442 grams of hydrogen per mile, or 48.83 miles per kilowatt hour, far more efficient than any battery electric vehicle can ever be. A single triple A battery weighs about 14 grams.
why do the electrones join back with hydrogen ions in the cathode? shouldn't those electrones go to the traction motor/ battery pack? or are those two situated in between anode and cathode reactions?
This vid is now two years old and there has been developments in hydrogen research and technology. It will undoubtedly pass battery technology in several years.
That's cool. Yet power plants should be surrounded closed system train tracks. Train cars with solar panel rooves. Then wind turbines inside the train cars, capture the wind drag to feed more electricity into train movement...Train can also cut power every minute and just run on momentum for 5-20 seconds...THEN inside train tracks have wind turbines in circular pattern capturing the wind energy of the train all around track inside and outside...The power can feed grid and or make hydrogen...Old train cars can be used and made lighter if necessary...They should charge all day and run all night, for at least the first run...Train cars might not even be necessary...small cars, connected will make same wind, and solar panels can line upper track, feeding the bottom cars like an automobile centipede.
@@Philipk65 Not necessarily, because if you crack windows wind gets in, but doesnt necessarily create drag. When you crack your car window you didnt create drag the car momentum doesnt offset anyway. It's recovering the kinetic motion energy. Train is just trying to break even. The turbines inside and outside the track are harvesting the wind energy.
Secondary and tertiary benefits of H2 will make H2 very beneficial e.g. H2 to make ammonia (NH3), to make fertilizer, to grow lots of food. Use of H2 for long haul truck (not possible via batteries) means economies can expand, jobs will expand, etc. A straight comparision on conversion efficiency is too narrow and flawed when looking at the Hydrogen economy.
Very well explaned as the difference between Hydrogen fuel cell and straight EVs. I do see the change. The thing to know and not discount is Petroleum is the best, highest desinty and renewable fuel on the planet. The problem of pollution is from the "internal combustion engine" efficentcy. The IC engine has been good up until now but is a major polluter. The answer is the "advanced fuel cell that converts petroleum directly to electricity or maybe should be call the "matter converter". Carbon has "excess" electrons, carbon is amazing and Rudolf Diesel had this answer as well as Tesla 125years ago on how to do this. The potential of carbon as in petroleum is fantastic. Petroleum comes from the core of the earth from atomic reaction of the core, this energy, heat condenses and condenses and becomes gas then it condenses and condenses etc to liquid. As this rises from the earth it does pick earth minerals and fossils elements. It doesn't come from fossil but does carry minerals and such up with it. This condenses and condenses etc to coal and finally diamond under certain conditions.
That's what I was thinking. This isn't quite a fair comparison. Either the EV needs to include losses in electrical generation, or the hydrogen car needs to begin at motor losses like the EV.
propane has carbon content which can pollute the air quality, that's why ev and h2 fuel cell are developed (majority sources of electricity and h2 also emit carbon tho 😀)
In HFC when efm gjves readkng at no load curcuit when hydrogen realsed or after hydrogen and oxygen both released? If only kne gas released what tbe e.mf for each gase released
Exciting technology however neither talks about the inefficiency of creating and transmitting our electrical energy. Perhaps we should hit pause on both EV and Hydrogen cars and divert R&D funding heavily into developing efficient clean electricity production as most of our energy still comes from burning fossil fuels. All these vehicles are doing right now are creating an overall carbon increase!
A hybrid car should be an electric volt car with a fuel cell, and regenerative breaking, along with solar roof, in addition to wind turbine speed hole. Then, use the car at a power plant to turn a turbine for power. It should be perpetual. Probably should be a truck.

Why have we not invested in this capability? It’s byproduct is water! We are literally suffocating ourselves with fossil fuel and creating a water crisis at the same time.
Graphic and its description flawed! you compare the entire cycle on the hydrogen side to an EV which has only stored energy made from something else go ahead and factor in the cold mind burned into electricity, transportation, losses, distribution charges, etc., etc. and you’ll see it’s not that far off
Came here for engineering but half of the video is commentary on the suitibilty and politics of hydrogen cars which by the way is mostly country specific and dependent on the infrastructure at place.
Yea, i also found that a strange statement. In what way is it not a fuel? Every fuel carries energy made from other processes, thats the nature of energy
Sorry to break this to you, but CO2 is not a toxic compound. It is a trace gas (0.04% of the atmosphere) that is absolutely essential in photosynthesis, the process by which it, along with water, is converted to food by plants. Without it there would be no plants, and we would all starve. Please note: IT HAS NEVER BEEN PROVEN that carbon dioxide is causing global warming!!! So burning fossil fuels for energy is okay. And we've so far used only about 1/15 of all the known petroleum deposits. Nuclear energy is the energy of the future.
I believe it would be complicated to confidently show this, but climatologists seem to be doing a pretty good job of showing stark correlations. It is logical to deduce that the exponentially increasing use of fossil fuels and subsequent misbalancing of the earth's gas makeup will have some unintended consequences.
@@enginuityexplained990The earth has gotten greener and more dense with vegetation since the industrial revolution according to NASA. Plants do grow bigger and faster when exposed to elevated c02 levels.
Wait wait let me see if I get straight. We, the same people who currently use garbage that bubbles out of the ground as a commodity should now trade that for using water which we need to live. Do you truly think that we will not commodify water if we do this?
Why does the fuel cell use oxygen from the atmosphere instead of the oxygen produced by electrolysis? This would be necessary to operate if not in earth’s atmosphere.
I am not sure I understand the question. Are you referring to the use of hydrogen for aerospace use? I don't know enough about the specific chemical reactions inside of the hydrogen chamber to give you an accurate answer unfortunately.
I just don't like batteries. Every device I have ever owned that used batteries has had battery issues. Somehow, putting them into a car is going to make them last longer...??? Maybe some day. If the hydrogen fuel cell can last longer, then I would go that route.
I guess every new technology has it's teething problems. Gasoline vehicles aren't without their problems either given how many moving parts they have. I believe that hydrogen and electrically powered vehicles are a step in the right direction.
@@enginuityexplained990 Yeah I am not against electric propulsion, but the problem is that the electric cars being made don't have less complexity despite what people think. The heat pump system in a Tesla, for example, is a really big deal. When that goes bad, it's going to be the equivalent of needing a new transmission. And when it dies, it renders the car useless. And honestly, what "new technology" is actually in them? AC induction motors are nothing new. Heat pumps are nothing new. The big, giant touch screen is relatively new. Batteries ARE better than they were 20 years ago and will hopefully improve. The software that runs everything is basically new. I don't like it when kids these days complain about how expensive things are, and now something even more expensive than before gets shoved on them.
except that the mining process to make batteries is still gonna put thousands of tons of pollution in the earth's atmosphere every day because the machinery is all diesel driven. plus the rare earths needed to make batteries is finite, what do we do when we run out of cobalt or lithium?
why cant hydrogen cars make hydrogen on board by reacting zinc with hydrochloric acid leaving behind hydrogen and zinc chloride or aluminium with con. sulfuric acid
Why wouldn't you go for the EV route? Well, if you live in a place where the power grid is absolute garbage. That is one consideration. Also, being able to fuel up even when power is out during a storm or an earthquake can be very important. Lastly, one that never gets discussed, is that all our our energy needs would be monopolized by a single utility company--this is made worse by the push to ban gas furnace, gas ovens, and now petrol cars too. For people that live in a country with a good electrical grid, I envy you, and I think EV can work in a place like that. But for me, hmm, our power equipment is all vintage where I live, don't know how they will manage all of that.
I agree that the changes required in infrastructure will be crucial in determining the success of any of these new potentially disruptive technologies.
You explained the energy chain for hydrogen, none such thing for the EV whose electric chain is assumedly coming from God here. Lol, how built in are the inefficiencies from the very plants that they're coming from in a battery vehicle? And what about all the combined resources to get the setup to be able to provide this energy in the first place to the power plant! what a shame, 'let's trace the energy chain'.
WHY DO YOU NEED TO HAVE HYDROGEN FUELED CARS?! WHEN YOU CAN BUILD HYDROGEN POWER PLANTS, THEN PUT THAT GENERATED POWER TO AN ELECTRIC GRID AND CHARGE YOUR ELECTRIC CARS )))))))) THAT'S ALL DONE WELL, SIMPLE AND EASY ;) AND BESIDES NO NEED FOR BUILDING ANY HIDROGEN REFUELING STATIONS 🤣🤣🤣
I guess it's another option on the journey to a more sustainable future. Battery/electrical powered vehicles are far from reaching their long-term viability point just yet with their high demand for rare metals and high energy input cost during manufacture. Hydrogen will potentially fill the gap for slower, longer distance transport. Over the next few years, it will be very interesting to see the developments in this space. Thanks for watching!
The "Zamboni" issue is not talked about if millions of Passenger and Commercial Hydrogen Vehicles move about on roads as a collective during below freezing temperature Seasons. I just can't wait for below freezing winter driving, as often found World wide, and here in the States where millions of Vehicles move about, when in a fully built out Hydrogen Future Energy Society where countless hydrogen vehicles have driven before us spewing mostly cool liquid state water exhaust droplets from a hydrogen fuel cell's 60-80C/140-176F exothermic reaction coating the roads with "black ice" for us to drive over and wreck our vehicles on ! Remember that liquid water begins to steam, when heated, to a higher 100C/212F Temperature. To start before embracing Hydrogen Vehicular Transportation please research the phrase "Black Ice". Next watch closely the Hydrogen Vehicle videos showing under high acceleration water mist vented conspicuously, and directed straight down coating the road surface. Watch the videos of people drinking Hydrogen Passenger vehicle tailpipe emissions by-product. Even " H2O '' liquid dump buttons flipped on from the drivers position. Are you in support of slips and falls in parking lots from countless, intentional winter temperature liquid water waste dumps left when leaving parking spots? Now that is safe ! This concept is just another, not so well thought out,"GREEN", idea that when applied into the real world, with millions of passenger and commercial trucks produced by so many manufacturers needed to fuel a society with hydrogen to keep us safe from climate change, does not keep us safe from injury or death when in vehicular accidents or falling down when encountering ice. A future Hydrogen Economy when built out, operating so many Hydrogen Vehicles that are spitting water on below freezing road or parking lot surfaces day after day in continual below freezing temperatures is not the answer ! It only takes a small patch of ice for a person walking to slip and fall. The key point is the state of the vehicle water emitted. Internal Combustion Engines (ICE) have high thermal heat output 250-800C/482-1472F and the resulting combusted fuel emissions cocktail comprises much less liquid water state exhausted as a portion per mile which is, in the case of an I.C.E. exhausted mostly instead as water vapor, which as we all know, is emitted as a gas vapor not settling on a road surface, but dissipating up as heat rising into the atmosphere. Present fuel cell designs drip much water, about a cup per mile, plentiful commercial Trucks / Lorries much more in the liquid state as the only single resulting byproduct, able to fall in a cool liquid form, ready to freeze on colder road surfaces. That is the difference. How about adding a steam heating unit to the fuel cell's liquid water by-product exhaust, this may be an energy intensive solution reducing mileage, and efficiency during winter driving, but lofting water vapor up off the road as ICE propelled vehicles now do. So, where to put the liquid water. Maybe an onboard tank to freeze solid and burst when parked? At a stop sign or light idling then accelerating adding heavy icing right there to the road surface just where one wants to actually stop? A parking lot to slip and injure another walking by the back of your parked vehicle or after you drove off leaving water to freeze there? A roadside gutter so a pedestrian can slip stepping off a curb, maybe falling down flat in front of stopped traffic and out of view of drivers ready to accelerate forward? Your driveway so you can fall there ? Your Garage to slide across while holding your infant child then both hitting the hard floor? Maybe, you need more tasks or to be distracted by mopping up the garage floor before the water freezes and your groceries just purchased thaw? Maybe a high speed highway perhaps in a turn? Maybe the unlimited speed limit Autobahn with high water production by those higher electric energy demands moving the hydrogen vehicle through the dense resistant air while simultaneously dumping large amounts of water mist under body contrails at high speed directed onto the road surface? Your Hydrogen Vehicle needs to relieve itself in public, The question is where to do it safely? Now considering these real world usage / interaction scenarios listed, are Hydrogen Vehicles a good idea? As a vehicle operator you can rate the chance of consistent, caring, and professional operator actions observed when you're out exercising your privilege to be with others in the public driving arena. Are you certain that rushed Hydrogen vehicle drivers find and maneuver over a public storm drain water dump station to let their hydrogen vehicle relieve itself in public places safely when freezing weather is happening? You rate and you decide if we or will not slip into a Hydrogen transportation based society. As for me...you guessed it, I see much more "could care less" vehicle drivers and very few careful vehicle drivers. Hydrogen supporters….should we give these "could care less" about you drivers a water soaker sprayer for society at large to walk or drive over when a dash indicator flashes an alert "water tank full" during your trip? As a example of related but current human behavior, How many times do you see trash / rubbish go swirling out of a moving pickup truck bed in the States, or dumped out a moving vehicle window instead of being caringly placed in a proper waste receptacle when arriving at one's destination, as an example of drivers' proper public disposal habits? Maybe add antifreeze to the water dump so it can mist on following vehicles windshields / windscreens then be smeared when wipers on, so the trailing driver has no clear view of the road. Now that is safe ! Then more windshield solvent , with poisonous methanol, is added to the ground by constantly spraying to keep a clear view. Now we're turning wipers on and off, as if that is not distracting to manage while driving in heavy traffic or oncoming bright sunlight in turns. Now that's safe. Maybe many Hydrogen Fueled Vehicles can dump water, and antifreeze, smearing trailing vehicle's glass view 360 degrees, that is now spread everywhere in the environment. Now that is green, think ! Maybe the Hydrogen Vehicle owner after the cost of a fill up of Hydrogen decides to not pay for the extra cost of perpetually filling an auxiliary antifreeze reservoir that costs more than gas or petrol per gallon. So where is the transportation fuel savings when buying both Hydrogen and Antifreeze for the fuel cell's water as a by product tank? Maybe granular or liquid salt treatment of ALL the roads ALL the time when temperatures are below freezing, even on sunny winter days ! Now raising the P.H. in streams from water mixed with salted trickling runoff 24/7/ all winter does not sound very Environmentally conscious or Green Think savvy. Get ready for higher taxes to pay the millions of dollars to pay for road treatment. Pay for replacing your scratched up paint. Pay for a broken windshield / windscreen when a chunk of salt is thrown on it during truck/ lorry application. Buying a new Vehicle often because your vehicle rusted prematurely from driving all winter on heavily salted roads. Maybe add vehicle exterior damaging or ICE engine air filter intake & cabin air filter clogging traction grit like coal furnace electric generation plant cinders or mined beach sand from environmentally sensitive areas to the below freezing road's surfaces 24/7 all winter to combat black ice on road surfaces, filling the streams with sediment to clog fish gills when stirred into the water column later by heavy rains to follow in warm weather. Now one has to think twice about opting for a green and healthy deep breathing bicycle ride or walk on a drier warm early Spring Day to work or for pleasure while breathing the leftover dust from many Winter months of road grit application stirred up by passing vehicles. Maybe the antifreeze adder system breaks or is disabled. Now the trailing driver is back to sliding on black ice in below freezing cold temperatures when Hydrogen is used in Vehicles as a transportation fuel spewing ONLY clean water onto the roads as the only by-product of its use. Possibly you or another will be in a hurry to turn into an urban area open parking space like so many hydrogen fuelled vehicles did before you after many back to back freezing days. Just think of how many possible times the same parking space is visited by a different vehicle on back to back below freezing days. Only to slide on black ice your vehicle's front bumper into the side door of or bumper of an already parked vehicle in the next parking space because of all the repeated water dumps released earlier by other shoppers under the hydrogen vehicle's body. : ( Here in the States most road temperatures fall below freezing during Winter, especially when traveling dark roads during long evening hours. Just imagine creeping with hundreds of other vehicles during slow rush hour traffic on road surfaces that are tilted, for warm weather water run off, door handle to door handle on multi lane interstates while hundreds of Hydrogen vehicles there with you drip water on to below freezing road surfaces. Yes you imagined what will happen when your vehicle slides toward or into the vehicle on the downgrade. Resulting in another hassel to fix your and the other driver's vehicle. I would bet vehicle monthly insurance rates will cost more to cover all the " Fender Bender" type accident claims caused by gravity sliding your Hydrogen vehicle downgrade into another. You decide, if adopting Hydrogen Transportation is in our best interest in the "Real World". Seems like a slippery slope to me ! How about you ? Are you still a Hydrogen Vehicle Transportation vehicle supporter? As for me, not so much unless you are living 365 days a year in an above freezing warm climate.

DC current will be of very low voltage to run the motors.Read more on Tesla model x
We’ll done sir! Clear and concise explanation .
Glad it was helpful!
So many videos had the basic electrolysis science wrong! Well done this is superb@@enginuityexplained990
NIce to see a proper explanation
Only one question to efficiency comparison, why didn't you count electricity production loses for EV, but only production loses for Hydrogen?
I did the math myself, fuelcell car has 49-54% efficiency after electrolysis and compression (I compress mine off of external green energy). Whereas a battery has voltage losses along a wire (which the h2 gas doesn't have when traveling to the fuel cell under 10k psi).
Process H2:
- Green Turbine power 100%
- Electrolysis, 72%
- Compression - 5%, but for my sake I just made an extra turbine setup to power it so 67%.
H2 to H20 Fuel Cell 48-50% efficient
The big lie revealed,
Battery Process:
- Green energy 100%
- ~5% from heat/voltage drop to 95%
- Funny enough, dc current makes electrolysis equivalent process store electrons on the plates of cathode and in o2 gas (very low energy density compared to compressed h2).
-77% resulting from battery charging.
- Voltage drop to electric motor -5%, 72% total
- Electrical motor prior to trans (75% efficiency), 54% total.
- Transmission -5% for torque conversion loss, total remaining power 49%
Yes this is comparable to a fuel cell car, but think! A battery like this is new, after 2-3 years a well maintained battery will lose 1/5 and roughly have 39% total energy. Whereas h2 tanks much like your gas tank doesn't change its capacity whereas a battery has corrosion on its surface plates = less capacity.
Further Cons of EV's:
- Must trickle charge constantly, h2 doesn't leak below 700bar.
- Letting battery charge drop below 60% has damaging effects as well as rapid charging it. Consequentially, a gas or h2 car has no effect on long time performance when driving close to Empty 😂😂😂
- The average users driving and maintenance habits will trash most EV batteries, Tesla included in 5-6 years (they claim 10 year warranty yet have a policy that excludes outdoor vehicles, constantly rapid charged vehicles, and etc.)
So for a couple dollar electrodes every month, I myself would prefer to you my wind power to make roughly 1lbs a day @ 3kw or in easier language terms 50miles of potential fuel a day.
Sad part is to charge a 160kwh EV is that on a fast charge it cost ~$45, as opposed to a gas sedan as of 09/24/22 only $38.70 @ 10gal. Best part is your H2 is free after about $1k investment into homemade wind/solar setup (solar probably closer to $2000ish).
A pro of H2 in comparison is that you can fill tanks while your away/ vehicle isn't home and they're easy to swap out the back of a vehicle in lower volumes or to make your or pressure release valve to fill an internal tank or a refill valve on the vehicle.

What is done with the waste heat? Can it be recovered?
Nice video! Don't you need to include the inefficiencies of generating the electricity that charges the batteries in the comparison?
It also applies to Hydrogen, inefficiency on energy generation also happens in hydrogen production which is emery intensive
That's what I was thinking. This isn't quite a fair comparison. Either the EV needs to include losses in electrical generation, or the hydrogen car needs to begin at motor losses like the EV.

Graphic and its description flawed! you compare the entire cycle on the hydrogen side to an EV which has only stored energy made from something else go ahead and factor in the cold mind burned into electricity, transportation, losses, distribution charges, etc., etc. and you’ll see it’s not that far off
alguem poderia traduzir esse vídeo ?
Came here for engineering but half of the video is commentary on the suitibilty and politics of hydrogen cars which by the way is mostly country specific and dependent on the infrastructure at place.
H2 is a true fuel
Yea, i also found that a strange statement. In what way is it not a fuel? Every fuel carries energy made from other processes, thats the nature of energy
Sorry to break this to you, but CO2 is not a toxic compound. It is a trace gas (0.04% of the atmosphere) that is absolutely essential in photosynthesis, the process by which it, along with water, is converted to food by plants. Without it there would be no plants, and we would all starve. Please note: IT HAS NEVER BEEN PROVEN that carbon dioxide is causing global warming!!! So burning fossil fuels for energy is okay. And we've so far used only about 1/15 of all the known petroleum deposits. Nuclear energy is the energy of the future.
I believe it would be complicated to confidently show this, but climatologists seem to be doing a pretty good job of showing stark correlations. It is logical to deduce that the exponentially increasing use of fossil fuels and subsequent misbalancing of the earth's gas makeup will have some unintended consequences.
@@enginuityexplained990The earth has gotten greener and more dense with vegetation since the industrial revolution according to NASA. Plants do grow bigger and faster when exposed to elevated c02 levels.
Shop them tanks out for H2O tanks and batteries to produce the hydrogen then us the vapor to power the car
Wait wait let me see if I get straight. We, the same people who currently use garbage that bubbles out of the ground as a commodity should now trade that for using water which we need to live. Do you truly think that we will not commodify water if we do this?
So hydrogen power is basically hydrogen battery
Hydrogen is the most explosive element on earth, and the atom is too small to contain. Fuel cells are an explosive idea!
Why does the fuel cell use oxygen from the atmosphere instead of the oxygen produced by electrolysis? This would be necessary to operate if not in earth’s atmosphere.
I am not sure I understand the question. Are you referring to the use of hydrogen for aerospace use? I don't know enough about the specific chemical reactions inside of the hydrogen chamber to give you an accurate answer unfortunately.
Sarawak malaysia will produce the first hydrogen in asia Sarawak Malaysia olso will host the international Carbon Confrence on 15 - 16 march 2023
I just don't like batteries. Every device I have ever owned that used batteries has had battery issues. Somehow, putting them into a car is going to make them last longer...???
Maybe some day. If the hydrogen fuel cell can last longer, then I would go that route.
I guess every new technology has it's teething problems. Gasoline vehicles aren't without their problems either given how many moving parts they have. I believe that hydrogen and electrically powered vehicles are a step in the right direction.
@@enginuityexplained990 Yeah I am not against electric propulsion, but the problem is that the electric cars being made don't have less complexity despite what people think. The heat pump system in a Tesla, for example, is a really big deal. When that goes bad, it's going to be the equivalent of needing a new transmission. And when it dies, it renders the car useless.
And honestly, what "new technology" is actually in them? AC induction motors are nothing new. Heat pumps are nothing new. The big, giant touch screen is relatively new. Batteries ARE better than they were 20 years ago and will hopefully improve. The software that runs everything is basically new.
I don't like it when kids these days complain about how expensive things are, and now something even more expensive than before gets shoved on them.
good content but the narrator talks too fast with a boring tone ...
except that the mining process to make batteries is still gonna put thousands of tons of pollution in the earth's atmosphere every day because the machinery is all diesel driven. plus the rare earths needed to make batteries is finite, what do we do when we run out of cobalt or lithium?
Salt batteries? That might be a good topic for me to research for a video.
why cant hydrogen cars make hydrogen on board by reacting zinc with hydrochloric acid leaving behind hydrogen and zinc chloride
or aluminium with con. sulfuric acid
Not sure people would be comfortable driving around a vehicle full of sloshing hydrochloric acid, but I could be wrong. Maybe you are onto something.
Cathode is positive, anode is negative
Anode is positive in electrolytic cells
Thanks for clarifying. I was getting confused myself there :-)
Why wouldn't you go for the EV route? Well, if you live in a place where the power grid is absolute garbage. That is one consideration. Also, being able to fuel up even when power is out during a storm or an earthquake can be very important. Lastly, one that never gets discussed, is that all our our energy needs would be monopolized by a single utility company--this is made worse by the push to ban gas furnace, gas ovens, and now petrol cars too. For people that live in a country with a good electrical grid, I envy you, and I think EV can work in a place like that. But for me, hmm, our power equipment is all vintage where I live, don't know how they will manage all of that.
I agree that the changes required in infrastructure will be crucial in determining the success of any of these new potentially disruptive technologies.
You react methyl hydrate solution and barrel its in lead braquet 😂
You explained the energy chain for hydrogen, none such thing for the EV whose electric chain is assumedly coming from God here. Lol, how built in are the inefficiencies from the very plants that they're coming from in a battery vehicle? And what about all the combined resources to get the setup to be able to provide this energy in the first place to the power plant! what a shame, 'let's trace the energy chain'.
That might be a good video for me to research next.
WHY DO YOU NEED TO HAVE HYDROGEN FUELED CARS?! WHEN YOU CAN BUILD HYDROGEN POWER PLANTS, THEN PUT THAT GENERATED POWER TO AN ELECTRIC GRID AND CHARGE YOUR ELECTRIC CARS )))))))) THAT'S ALL DONE WELL, SIMPLE AND EASY ;) AND BESIDES NO NEED FOR BUILDING ANY HIDROGEN REFUELING STATIONS 🤣🤣🤣
I guess it's another option on the journey to a more sustainable future. Battery/electrical powered vehicles are far from reaching their long-term viability point just yet with their high demand for rare metals and high energy input cost during manufacture. Hydrogen will potentially fill the gap for slower, longer distance transport. Over the next few years, it will be very interesting to see the developments in this space. Thanks for watching!
The "Zamboni" issue is not talked about if millions of Passenger and Commercial Hydrogen Vehicles move about on roads as a collective during below freezing temperature Seasons. I just can't wait for below freezing winter driving, as often found World wide, and here in the States where millions of Vehicles move about, when in a fully built out Hydrogen Future Energy Society where countless hydrogen vehicles have driven before us spewing mostly cool liquid state water exhaust droplets from a hydrogen fuel cell's 60-80C/140-176F exothermic reaction coating the roads with "black ice" for us to drive over and wreck our vehicles on ! Remember that liquid water begins to steam, when heated, to a higher 100C/212F Temperature. To start before embracing Hydrogen Vehicular Transportation please research the phrase "Black Ice". Next watch closely the Hydrogen Vehicle videos showing under high acceleration water mist vented conspicuously, and directed straight down coating the road surface. Watch the videos of people drinking Hydrogen Passenger vehicle tailpipe emissions by-product. Even " H2O '' liquid dump buttons flipped on from the drivers position. Are you in support of slips and falls in parking lots from countless, intentional winter temperature liquid water waste dumps left when leaving parking spots? Now that is safe ! This concept is just another, not so well thought out,"GREEN", idea that when applied into the real world, with millions of passenger and commercial trucks produced by so many manufacturers needed to fuel a society with hydrogen to keep us safe from climate change, does not keep us safe from injury or death when in vehicular accidents or falling down when encountering ice. A future Hydrogen Economy when built out, operating so many Hydrogen Vehicles that are spitting water on below freezing road or parking lot surfaces day after day in continual below freezing temperatures is not the answer ! It only takes a small patch of ice for a person walking to slip and fall. The key point is the state of the vehicle water emitted. Internal Combustion Engines (ICE) have high thermal heat output 250-800C/482-1472F and the resulting combusted fuel emissions cocktail comprises much less liquid water state exhausted as a portion per mile which is, in the case of an I.C.E. exhausted mostly instead as water vapor, which as we all know, is emitted as a gas vapor not settling on a road surface, but dissipating up as heat rising into the atmosphere. Present fuel cell designs drip much water, about a cup per mile, plentiful commercial Trucks / Lorries much more in the liquid state as the only single resulting byproduct, able to fall in a cool liquid form, ready to freeze on colder road surfaces. That is the difference. How about adding a steam heating unit to the fuel cell's liquid water by-product exhaust, this may be an energy intensive solution reducing mileage, and efficiency during winter driving, but lofting water vapor up off the road as ICE propelled vehicles now do. So, where to put the liquid water. Maybe an onboard tank to freeze solid and burst when parked? At a stop sign or light idling then accelerating adding heavy icing right there to the road surface just where one wants to actually stop? A parking lot to slip and injure another walking by the back of your parked vehicle or after you drove off leaving water to freeze there? A roadside gutter so a pedestrian can slip stepping off a curb, maybe falling down flat in front of stopped traffic and out of view of drivers ready to accelerate forward? Your driveway so you can fall there ? Your Garage to slide across while holding your infant child then both hitting the hard floor? Maybe, you need more tasks or to be distracted by mopping up the garage floor before the water freezes and your groceries just purchased thaw? Maybe a high speed highway perhaps in a turn? Maybe the unlimited speed limit Autobahn with high water production by those higher electric energy demands moving the hydrogen vehicle through the dense resistant air while simultaneously dumping large amounts of water mist under body contrails at high speed directed onto the road surface? Your Hydrogen Vehicle needs to relieve itself in public, The question is where to do it safely? Now considering these real world usage / interaction scenarios listed, are Hydrogen Vehicles a good idea? As a vehicle operator you can rate the chance of consistent, caring, and professional operator actions observed when you're out exercising your privilege to be with others in the public driving arena. Are you certain that rushed Hydrogen vehicle drivers find and maneuver over a public storm drain water dump station to let their hydrogen vehicle relieve itself in public places safely when freezing weather is happening? You rate and you decide if we or will not slip into a Hydrogen transportation based society. As for me...you guessed it, I see much more "could care less" vehicle drivers and very few careful vehicle drivers. Hydrogen supporters….should we give these "could care less" about you drivers a water soaker sprayer for society at large to walk or drive over when a dash indicator flashes an alert "water tank full" during your trip?
As a example of related but current human behavior, How many times do you see trash / rubbish go swirling out of a moving pickup truck bed in the States, or dumped out a moving vehicle window instead of being caringly placed in a proper waste receptacle when arriving at one's destination, as an example of drivers' proper public disposal habits?
Maybe add antifreeze to the water dump so it can mist on following vehicles windshields / windscreens then be smeared when wipers on, so the trailing driver has no clear view of the road. Now that is safe ! Then more windshield solvent , with poisonous methanol, is added to the ground by constantly spraying to keep a clear view. Now we're turning wipers on and off, as if that is not distracting to manage while driving in heavy traffic or oncoming bright sunlight in turns. Now that's safe.
Maybe many Hydrogen Fueled Vehicles can dump water, and antifreeze, smearing trailing vehicle's glass view 360 degrees, that is now spread everywhere in the environment. Now that is green, think !
Maybe the Hydrogen Vehicle owner after the cost of a fill up of Hydrogen decides to not pay for the extra cost of perpetually filling an auxiliary antifreeze reservoir that costs more than gas or petrol per gallon. So where is the transportation fuel savings when buying both Hydrogen and Antifreeze for the fuel cell's water as a by product tank?
Maybe granular or liquid salt treatment of ALL the roads ALL the time when temperatures are below freezing, even on sunny winter days ! Now raising the P.H. in streams from water mixed with salted trickling runoff 24/7/ all winter does not sound very Environmentally conscious or Green Think savvy. Get ready for higher taxes to pay the millions of dollars to pay for road treatment. Pay for replacing your scratched up paint. Pay for a broken windshield / windscreen when a chunk of salt is thrown on it during truck/ lorry application. Buying a new Vehicle often because your vehicle rusted prematurely from driving all winter on heavily salted roads.
Maybe add vehicle exterior damaging or ICE engine air filter intake & cabin air filter clogging traction grit like coal furnace electric generation plant cinders or mined beach sand from environmentally sensitive areas to the below freezing road's surfaces 24/7 all winter to combat black ice on road surfaces, filling the streams with sediment to clog fish gills when stirred into the water column later by heavy rains to follow in warm weather. Now one has to think twice about opting for a green and healthy deep breathing bicycle ride or walk on a drier warm early Spring Day to work or for pleasure while breathing the leftover dust from many Winter months of road grit application stirred up by passing vehicles.
Maybe the antifreeze adder system breaks or is disabled. Now the trailing driver is back to sliding on black ice in below freezing cold temperatures when Hydrogen is used in Vehicles as a transportation fuel spewing ONLY clean water onto the roads as the only by-product of its use.
Possibly you or another will be in a hurry to turn into an urban area open parking space like so many hydrogen fuelled vehicles did before you after many back to back freezing days. Just think of how many possible times the same parking space is visited by a different vehicle on back to back below freezing days. Only to slide on black ice your vehicle's front bumper into the side door of or bumper of an already parked vehicle in the next parking space because of all the repeated water dumps released earlier by other shoppers under the hydrogen vehicle's body. : (
Here in the States most road temperatures fall below freezing during Winter, especially when traveling dark roads during long evening hours. Just imagine creeping with hundreds of other vehicles during slow rush hour traffic on road surfaces that are tilted, for warm weather water run off, door handle to door handle on multi lane interstates while hundreds of Hydrogen vehicles there with you drip water on to below freezing road surfaces. Yes you imagined what will happen when your vehicle slides toward or into the vehicle on the downgrade. Resulting in another hassel to fix your and the other driver's vehicle. I would bet vehicle monthly insurance rates will cost more to cover all the " Fender Bender" type accident claims caused by gravity sliding your Hydrogen vehicle downgrade into another.
You decide, if adopting Hydrogen Transportation is in our best interest in the "Real World". Seems like a slippery slope to me ! How about you ? Are you still a Hydrogen Vehicle Transportation vehicle supporter? As for me, not so much unless you are living 365 days a year in an above freezing warm climate.
Chill out dude!
@@cmms566 I am "chilled oit". That is the point made, as we slip slide away when driving.
If this is the issue then India is perfect for using Hydrogen fuel cell as far as climate part is concerned.
ok but picture this
instead of exhausting the water onto the road
put it in my mouth
mmm water
imagine commuting to work and having the exhaust from your car piped through a coffee maker and directly into a mug on a cold winter day
mmm coffee
Have Elon arrested and bring out the true Nikola Tesla……
Are you retarted
He named it after him for a reason……..
