When I was about 8 years old, my dad took me to his work. Circa 1963. He showed me the fork lifts charging with electricity. These were wet cell batteries, 4' X 4' X 4' and about 1,000 lbs. These fork lifts were used indoors because no emissions.

With forklifts weight is not a problem - if it weren't for those heavy batteries they'd have to weigh them down with extra dead weight to balance the load up front.

[@johnkarakash]

Nice comparison but you left out a tiny matter when you were talking about refilling (well, you hinted at it). 99% of the 'fillups' from your typical driver (compared to ICE cars) vanish when you recharge overnight. The only time someone will need to charge away from home are a) longer trips and b) forgetfulness. If you have your future EV automatically remind you to plug in when you get home, you're golden!

[@midi510]

Needing to be reminded to plug your car in when you get home is like needing to be reminded to wipe your arse after you take a shite. 🤣

I had a job where the parking lot had some electric recharging spaces. Cheap and easy cuz you can do it over 8 hours. Bad if you have to go back and disconnect to let someone else charge.

[@ChaJ67]

Hydrogen is just an energy carrier when used with electrolysis. So let's see how it stacks up to a battery, what you probably should have spent this video doing: 1. Safety: Battery is good. Maybe it can catch on fire, maybe it can't. Depends on the chemistry and other safety factors around it. Not the easiest thing to get to burn, even if it is a chemistry that can. This is overall better than say gasoline, which is highly flammable. Hydrogen is bad. When hydrogen goes wrong, it goes really wrong, as in big boom. There have been some station explosions around the world and it has been catastrophic. This has led to hydrogen being banned in some developed countries. Hydrogen cannot scale up because of safety issues. Eventually you have big explosions and it gets banned. 2. Cost efficiency: Batteries are either moderately or very highly efficient depending on how exactly the batteries are setup. This tends to lead to batteries being cheap to operate. This is key for something like trucking where you need to keep costs of energy down as moving a truck down the road uses a tonne of energy. At this battery electric, at least when done right, is extremely low maintenance, leading to even lower operating costs. Hydrogen has very poor efficiency and will never be good. This leads to high costs in addition to the extremely expensive hydrogen fuel cells. Just way too expensive for a semi-truck in a competitive market. At this trucks run fixed routes and truck drivers, at least in the USA are required to take breaks every 4 hours or so. So for batteries it is easy to plan electrical charging stops to coincide with breaks truckers are mandated to take. At this at least historically hydrogen fuel cells in addition to their great expense have been somewhat delicate. If you have ever paid attention to the trucking lane in a lot of places, it gets pretty torn up from all of the heavy / overloaded trucks going down the road and thus a great way to break a super expensive hydrogen fuel cell. So cost efficiency of hydrogen fuel cells is terrible and not something you want to run your for profit trucking company with for example. 3. Corrosion: Battery chemistry used for automotive use is usually a pretty hardy chemistry that can last for a while. A hydrogen fuel cell system needs to be made with special materials as hydrogen is highly corrosive. Any quality control issue with hydrogen fuel cell vehicles can lead to massive fires and explosions. 4. Range extension: With battery tech, there have been demonstrations on how to do wireless charging going all the way back to Nikola Tesla over 100 years ago. Wired power transfer has been around a long time to. We certainly have ways to make a battery electric vehicle have basically unlimited range without stopping by electrifying the main thoroughfares, leaving batteries for the surface streets. It is just a matter of selecting a standard and mass implementing it, such as wireless power transfer in the roadway. We have a wireless charging standard for our cell phones already. With battery electric, you can also do things like have a camping trailer with batteries and solar onboard and connect the electrical systems of the towing vehicle and trailer so that the batteries in the trailer act for range extension. Then when you get close to your destination, top off charge and go the last mile on internal power alone so the trailer has plenty of battery for off grid camping. If on grid camping, the trailer can be depleted getting to the destination and then plugged into a NEMA 14-50 outlet, charge up, and also have the vehicle plugged into the trailer overnight so they both charge off of a single outlet. Even the AC Propulsion T-zero back in the day had range extending trailer options built and demonstrated, granted that was more focused on a gasoline engine / generator deal. With hydrogen, all you can do is add more tanks of highly compressed hydrogen rocket fuel, which sounds dangerous to me. Could you imagine for example hauling a big hydrogen trailer around and getting rear-ended or having a hose leak? How many times have you seen a trailer going down the road with something dragging and sparking at the connection point between vehicles and could you imagine if that was a hose with hydrogen compressed to 10,000 psi?

Power paste is a game changer for hydrogen.

[@jk6561]

Interesting. I agree, there is a place for both technologies. My issue with EV's is in the mix of energy used to generate the electricity. Great if it's from renewables i.e. zero carbon but if the majority of your energy mix is coming from coal, gas or biomass without carbon capture then you are driving a low carbon and pollution free vehicle but the problem still remains at the source of electricity generation. I think if there are times when renewables are generating excess energy and it can't be stored then why not make some clean hydrogen on the way?

[@martinhammett8121]

Ive seen a couple of videos , they say the best use of green hydrogen would be to de-carbonize Fertilizer production ! . It could also be used to replace gas used in steel production !

[@beatreuteler]

I saw a similar video that said electrolyzers used only to convert excess green electricity to H2 at times there is indeed excess will never work economically because there are not enough operation hours annually to pay the equipment. I don't know the background well enough to judge but thats what was said.

[@gavinkemp7920]

And even for semi it is debatable. First the drivers have mandatory breaks, in france it 45 minutes every 4 and a half hours, I don't know if that hits a sweet spot but that time that can be used recharging. In europe we are also exploring electrifying the motorways to alloy for charging while driving.

Elon has already determined that hydrogen maybe abundant but it is costly to handle to work on mobile devices. For 3 decades, fuel cell has been studied almost throughly.

Fuel cells have been studied for at least 5 decades, not 3. And while scientists may have determined H2 is the most abundant element, Technicians have determined it is not. Water and hydrocarbons are, but H2, while part of these, is not because you can't get ahold of it unless you have energy at hand to separate it from these.

[@winnythekahuna8073]

Batteries are still too heavy and take up a lot of space. Once the tech to split H2O to gain hydrogen matures, then fuel tankers wont be required because the fuel stations will just supply and manufacture the hydrogen direct to consumer. The advantage of hydrogen is that it can be more useful for large machines like ships, trains, airplanes etc. As for the conventional designed family car, maybe batteries have the edge at the moment. Although a hydrogen powered turbine engine has a high efficiency, can also produce lift or downforce, whilst possibly also generate current for a capacitor to power an electric motor.

I think Tesla (this is much more than just Elon Musk), has no real reason to worry about Toyota. It was figuread that range is not the big issue that many people think it is. That is why a 3 times the range-value on a drone does not make H2 a good solution. The Toyota Mirai for example has less range than most of the better BEV's.

[@dannypope1860]

The hydrogen fuel cells aren’t the issue. The storage and transport of massive amounts of hydrogen around the country is the problem. It’s very expensive, dangerous, and inefficient. It’s much for efficient to get your vehicle’s fuel directly from the power grid.

[@pirate0jimmy]

Genuine efficiency is burning liquid fuels and using electric drive, stopstart as range extenders. 10% electric car load vs. current traffic totally demolishes electric grid. In US NE a Tesla and all other electric vehicles are COAL BURNERS. A VW 1L Diesel electric with a small battery (10 miles, 35mph max) gives max FREEDOM to owner with minimum emissions in current infrastructure.

[@jlnger149]

I agree, It's very expensive for hydrogen. Even if investors and pioneers of the technology develop a way to make hydrogen on-site to reduce/eliminate transport costs, it's still going to be inefficient and expensive.

[@domenicobarillari2046]

I find this presentation very honest and sensible...thank you for you efforts. I regret that, as a practicing physicist and engineer, I must agree with EM on this particular topic, as well as the specifics given below by the other critical responders before me who gave 90% of the bad news. All I would add is that, at around the 9:00 time mark, any defense of hydrogen gets worse by the attempt to bring in "green hydrogen" from solar and wind sources. These latter electrical sources are anything but actually green : land hungry and intermittent in character, with equipment still intensively produced by existing industrial methods that are barely an improvement in the overall scheme of things to just raking coal into the thermal power stations. With years occasionally advising venture capital groups on this from I hope a God-honest perspective, put your bets elsewhere -after all, as I have to relentlessly explain, it must be economically measured as an energy conveyance, never an actual source as certain chemical industry consumers of hydrogen are entitled to see it. Best regards.

[@johnowens8992]

Agree that so called rebewables are anything but , personally I think quit messing around and use fast breather nuclear fission until fusion is perfected. However wind and solar are being adapted on huge scales so this will lead to high latentceys to try get away from gas , i.e 2x capacity to meet demand at 50% capacity (those are my own predictions but are just for an example) so at 80% capacity there will be vast amounts of ecxess power leading to curtailment , which is already happening in scandenavia, current battery tecnologies wont come close to meeting the TWH scales to meet this imbalance , DC UHV interconnectors may have a roll but are unlikely to completely solve the issue , this is where green hydrogen will step in using cheap excess power to run electrolysers. This will firstly displace grey hydrogen but will scale up quickly, on a side note hyrogen has been transported for industrial uses with few issuess and is relatively safe in cars as it dissipates quickly as it is so light. On the EV side minerals will become increasingly expensive as battery production continues to increase exponentionally and in reality most people rarely need more than 50-100 miles of rage per day. So it will not make sence to make a 400-500 mile range battery , this is where I believe h2 hybrids will fill the gap on the occasional time you need a longer range where a small h2 cell will continuously top up a battery on longer journeys.

[@domenicobarillari2046]

@@johnowens8992 Hello John Many interesting and good points - too many to address at once (perhaps due to the edit applied to your original submission?). As primarily a nuclear industry person in my earlier career, I am very prejudiced towards the fission option, especially if we can get away from U235-based (i.e., open, wasteful "cycles".) I would mainly add that adding more nuclear does play primarily into the EV industry goals, with a potential for secondary hydrolysis-based energy storage use - for what ever purposes. Still keeping the nuclear engineer's perspective, we DO like technologies that help to alleviate load shifting, as almost all fission modes of energy generation are best applied to providing base load and NOT swinging demands (e.g., of the typical consumer day-time use cycle.) Forcing most cores to work in demand mode runs the risk of instabilities. best regards Domenico

Tesla semi would be excellent at short to mid range, but would suck at long haul. I heard that would cover more than 50%-75% of the semi usage, (I am not sure from where.) Hydrogen semi would be seriously overkill at short to mid range. But if you only use the hydrogen semi for long haul, you can get away with not having any filling stations at all, because you can cheaply transport the liquid hydrogen from the nearest industrial site (relatively speaking). Basically you can have mobile filling stations, because hydrogen energy density is so amazingly high. The technologies complement each other near perfectly.

I did the math I’m using hydrogen for an airplane and it does not look good. The problem is for the same quantity of energy they would get from aircraft fuel, hydrogen tank would be 3 1/2 times the volume of existing tanks. There is simply not enough room in aircraft wings to fill them with hydrogen. Add to that that the tanks need to withstand 10,000 psi and he quickly see that aircraft fueled by hydrogen is a virtual impossibility. Just take a look at the size of the hydrogen tanks on a Toyota Mirai to put things in perspective and that has a tiny motor in it which is necessary because they simply can’t stuff that much energy into a vehicle. I doubt you’ll ever see a commercial application of hydrogen aircraft ever. As far as trucks is concerned the economics would prevent hydrogen from being used since it cost twice as much as gasoline.

This conversation again?! I am getting tired of it. First off, Good video. You pointed out a good chunk of the factors and subjects that are involved. But a few key one are missing. Here we go: 1. As mentioned in the video, Current modern Rechargeable batteries (RB) like li-ion have a vrey short effective lifespan (roughly 2 years in most E-Cars). Adding to that, RBs are susceptible to temperature changes, Resulting in a loss of efficiency and charge holding capacity. Depending on the scenario RB-Cars can lose up to 65% (or even more) efficiency. Also it ages the cells faster, shortening their lifespan greatly. Making them not reliable and extremely inefficient over time in the majority of the world. 2. Most of the Electric grids around the world (which especially first world countries are affected by) cannot support a full conversion to RB-cars. Meaning the Infrastructure needs to be upgraded which is a enormous, expensive and time consuming undertaking. 3. There are other Hydrogen conversion methods besides fuel cells. Like Hydrogen Combustion engines. 4. Hydrogen as said in the video, is a better medium to store energy in / is more energy dense than BRs. 5. As pointed out by others. Hydrogen could be produced in regions that experience a higher energy surplus. Or more Efficient methods of electric energy generation could be used. Like molten salt trinium reactors. Furthermore multiple studies have shown that "renewable energy" solutions like wind-turbine-parks are actually not efficient and seem to have a different negative impact on the environment. In short No. Hydrogen is not "Stupid"(which by the way is an extremely weak argument). Its just the industry around cars, that a short while ago, started to invest more and more into BR-Technologies and doesn't want to be told that they have bet on the wrong horse.

• Nano aluminium powder (ie a gallium/aluminium amalgam) is oxidised in water to release 100% heated hydrogen gas and an alumina residue (the gallium catalyst is fully recoverable). • The hot hydrogen gas self-ignites in a venturi to form an ionised gas or plasma that drives an MHD electrical generator. • Aluminium metal and useful metal oxides can be reconstituted from the alumina residue (without electrolysis) by adding highly reactive metals such as potassium or sodium (eg 5.52 gm of metal sodium reacts with 6.52 gm of aluminium oxide to yield 1.50 gm of metal aluminium). The chemical reactions are: Potassium: 6K + Al2O3 → 3K2O (potassium oxide or potash) + 2Al. Sodium: Na + Al2O3 → Na2O (sodium bicarbonate) + Al Potassium oxide also reacts with carbon dioxide to produce potassium carbonate so it not only forms a useful industrial product but it can sequester a climate warming gas. K2O + CO2→ K2CO3 Similarly, sodium oxide reacts with carbon dioxide to form sodium carbonate (washing soda) so it might also form a useful industrial product along with sequestering a climate warming gas. 2Na2O + 3CO2 → 2Na2CO3

There are a few more problems not mentioned here. #1 There isnt enough platinum in the world to make fuel cell for every vehicle to be hydrogen powered. Thats a big issue. It has one potential solution, a few years ago a really big asteroid flew by that was made up entirely of platinum, so much so that if we bring it back to earth, platinum becomes worthless. So there is a way to get more, it just may be really hard and really expensive to get it. There are alternate materials, like copper, but they are FAR less efficient, their are combo materials, that have tradeoffs, but still no great and work to make new materials, but no breakthroughs yet. #2 Hydrogen is so small that its impossible to store, it leaks out over time and this cant be stopped. #3 hydrogen makes any metal its contained in more brittle with time, this is bad as hydrogen is explosive if ignited and you are sitting on a tank of the stuff. Even if repairs are made to parts every few years, its not cheap the replace the guts of your car every few years. #4 if dangerous to transport, its explosive, enough so to blow up a city block, so its too dangerous to transport at scale and must be made locally. #5 alternate method to transport it is by turning it into ammonia(which makes things even less efficient), that is 3 hydrogen molecules instead of the normal 2, it also makes it more dense, great for transporting it. But it has a problem, if it leaks it forms a white cloud below 10 feet of an incredibly strong acid capable of melting organic matter, humans are organic. So if a tank pops you see a white cloud "thats weird" and if you breath it in, it will MELT your lungs. This stuff in a city being transported at scale is a nightmare, i dont know which is worse, #4 or #5. Again, hydrogen made locally is the only option. #6 real world issues popping up now that its in use. Hydrogen is fast to fill up your car, right? wrong... as people are discovering, hydrogen is really cold and when moisture hits cold surfaces it freezes into ice. over the course of 5 minutes it makes so much ice that the nozzle is freezing to the car and you have to wait 10 minutes for it to unthaw. Not exactly fast... but you can build a heater into the nozzle which makes things even less efficient? not a problem that cant be solved. But lets look at that "45 minutes to fill up" figure, that may be true for some EVs, but charge speed peaks at the start and goes down towards the end, that last 10-20% takes the longest, there is just no reason with all the tesla chargers around to fully charge up, and if you do that, it takes to 15 minutes instead, most people find that taking a break on a trip takes at least 15 minutes so its not exactly a problem, and there are enough chargers where you can fill up twice before you run out even if you only go up to 80%. Most people also dont travel that much, you could opt for a lower range model and save money and simply rent a longer range car for a trip. Overall, the benefits of hydrogen are not huge and the benefits of batteries arnt as bad as people suggest and it does improve with time.

[@rafbambam]

One thing that is overlooked in all these kind of videos is the part where the car/truck has a technical problem. Like all cars and trucks the electrical ones will brake down ones in a while. For cars the problem is not that mutch of a deal, but for trucks this is a big deal. Have you ever seen how they tow a truck, it's not on a flatbed; it's by lifting up the front or rear axel and driving them this way to a save place or the garage. With ICE trucks there is no problem; the tower "just" has to disconect the motor from the wheels (via the shaft) and it can be towed. But with electrical transport the motor is right on the axel; so it can't be disconected. In other words if you tow a electric vehicle in that way you are spining the motor. And if it is for short distances, like pulling it up on to a flatbed, it's not a big deal. But to take the truck for a tow that can be over several hundres kilometers, it will be a problem. There are two major problems, first the motor could get stuck and break even during he tow (becource there is nothing cooling the motor down, for the truck is not powerd on), he second problem is that the motor can become a dynamo (recharger) and it will produce power (or back to the batterie, or it can be conected to something that draines that power), but this is a great hazzard. This is a big problem for towing companies, and the companies that have the bad luck that theyre truck had been broken down. Becource who is going to cover those repair costs if these problems happen whyle towing. And the biggest problem is when a truck had an accident, where the batterie has sufferd damage; it may catch fire (expecialy when towing). I don't think that any person in there good mind wants to be towing a truck that starts to burn. And now we are on the subject of burning electrical trucks; how can you shut the fire down? With an electric car that car needs to be lowerd in an container filed wih water for 48h, to avoid restarting fires. How in heavens name would you do that with a truck? Don't get me wrong I love to drive a Tesla semi in the future (I'm a truck driver in Europe), but there is nobody today that can solve the problem of a burning electrical truck. And I know that in normal use this is not a problem; but if it happens in an accident (between trucks) there is no option of "just" letting the truck burn out, becource that will hapen next to a highway or a big road, and it would take a long time for the truck to stop burning, and the damage to the road and suroundings would be enormes. Not to mension the toxic fumes that will be set free from the fire. And with hydrogen the problem will be even bigger, becource trucks will have (small) batteries (to charge when slowing down the truck) but the hydrogen tanks are litteraly boms when the truck would catch on fire. And that is even a bigger problem for everybody close to the truck on fire. Just some thoughts regarding the future of oure transportation. Greetings from Belgium.

[@jessiejanson1528]

seems like an obvious problem and im sure it isnt one. because if it were a problem, with all the companies and people making a fuss every time something happens with a tesla, they would be all over them if they couldnt be tower. in general, to deal with the fire, you just need to douse them in water to cool them down because its the heat that makes them burn from a short circuit in the batter from damage. So you could dump the battery in a pool of water for a few days until any damaged cells fully discharge, then they wouldnt be at risk of shorting and burning. not exactly simple to do on the highway, but there is a path forward and in general crews are pretty good at handling EVs. Accidents do happen less with teslas, but once self driving tech is here and working, accidents will start to become a thing of the past. Some companies are also sealing batteries in a compartment with no air to prevent a fire from starting, they just burn out in place. There was actually a car company doing this and some news awhile ago about them scamming customers, i cant remember which brand it was off hand id probably say the wrong one if i guessed. But the story is basically that the battery is bigger then expected without the drivers having full access to it(and no i dont mean teslas) in some cases the cars were losing range and it turns out the battery sections were burning up and the battery stopped charging them when it senses this but it results in a permanent loss or range. This company would "fix" it by "replacing the battery", but they were just unlocking part of the unused battery, which also suggests they knew this was a problem from the start. The problem is that despite the cars being under warranty, they were still charging people and arm and a leg to "replace the battery" when they were really only doing a software fix that isnt a permanent solution. I havnt heard anything about this in about 4-6 months and i had forgetting it until just now, i suppose this ended up in court with the situation sealed and resolved, you know those NDAs "if you want it fixed for free, sign this and agree to not talk about it". For the record, BMW had issues like this as well, their ICE cars were bursting into flames and they had no idea how to fix it, they just told owners to park them in the driveway until they could figure it out at some point. If you wanted the fix you had to sign their NDA, but someone leaked it anyway.

There is a role for hydrogen and fuel cells, but only if the hydrogen can be produced affordably and not add to our current greenhouse gas problem. Like you say, there are some applications where hydrogen fuel cells are potential more beneficial, but let's not forget many of today's hydrogen fuel cell vehicles still need batteries (although not as large a battery only EV) to temporarily store the energy produced by the fuel cell before it is fed to the electric motor(s). May be in the future we will be extracting hydrogen gas from the gas giants in our solar system.

The electric grid will NOT be overloaded. Governments (already happening in Europe) will be MANDATING Internet (aka Smart) connected car chargers. This way, government regulators can shut off your home car charger remotely and ration how much they will allow you to use it. Because of solar panels, there's more power available during the day than there is night (or cloudy weather). They're using this to prevent electric car owners from charging at night, or when the electrical grid is under heavy use. The best solution is to own 2 electric cars so that you can have one "available" to charge while you're driving the other one.

Are there temperature issues for hydrogen? What's the expected lifespan of fuel cells? How long would it take to charge a heavy EV truck? What's the procedure when either one runs out of fuel? If you want to keep your vehicle for a longer time (say, 10-20 years if you're environmentally concerned), which fuel type is less expensive over the long run? What's the environmental cost of making a Tesla vs that of making a fuel cell vehicle, and how many miles would you have to drive each one (given green power sources) to neutralize the eco cost of actually building the car?

Hydrogen fuel cells also have another completely overlooked downside - they need quite lot of oxygen (approx. 8kg of oxygen for 1kg of hydrogen). That could be huge problem for scenarios like underground parking, garages and closed spaces dependent on air ventilation in general. Even long uphill tunnels could be problematic if majority of cars would be running on hydrogen. For example, if you turn on air conditioner in hydrogen car parked in small garrage (which can be done remotely in modern cars), oxygen level would drop below minimum required for human survival in about 30 minutes.

[@TheSudder]

H2 has roughly 3 times the energy-density of petrol per kg, and Petrol needs roughly 3 kg O2 (14,8kg air) for the combustion -> combined with the higher efficency, a FC would need less O2 than an ICE would for the same ammount of power..

I would assume if you had all the gas cars running at the same time in an underground tunnel or parking facility one would have other issues to worry about, such as breathing. However, in both cases increasing ventilation should take care of this.

Man did you simplify a very complex subject.. sadly in the simplification you really didn't show just how bad hydrogen is...Hydrogen isn't anything but stupid. It's efficiency is much lower than a battery powered vehicle. You use electricity to make hydrogen they compress and deliver the hydrogen to the refill stations. Then folks fill up and the hydrogen is turned back into electricity to power a vehicle. That's multiple steps, lots of cost, and lower efficiency than just using the electricity that we are already surrounded by. Battery electric cars are about 75% efficient based on the total electricity produced while hydrogen is about 30% efficient. That's not to forget that hydrogen is hard to store for very long and to use as a fuel must be either liquefied, pressurized, or mixed with something else to act as a carrying agent. None of those options come without cost or problems. Who spends billions of dollars to provide the most in efficient of two systems? Elon doesn't product hydrogen fuel cells because they don't make sense. Not because he has an interest in battery electric cars. He could easily produce all the Tesla semi and simply put in a fuel cell and storage tank with little problem and he would if it were a good idea. This is certainly the most disappointing video you have produced. It's just fuel to feed the FUD around hydrogen. Do some real research and quit spreading the narrative that big oil wants to promote. They would love to just produce another fuel that we go out and fill up with so they have something to replace the oil/gasoline business.

The used battery is recharged by the road wheels while the stand by battery becomes the main battery where the cycle repeats. The problem with my idea is the lasting power of batteries is finite. Batteries can only take so many recharges before they become inefficient at being recharged to a extent we have to replace them which is expensive for the age of the vehicle. The second flaw slow moving city traffic jams is an insentient electrical generation at slow moving stopping and starting in life of the vehicle.

I do think Tesla cars on a level 3 Supercharger can be charged from 20% to 80% in about 20, not 45 minutes, but that is not the capability of all the other BEVs out there in CCS DC Fast Charging and much of that is dependent on the thermal management of the pack, read Ethylene glycol pumps, radiator and fan, the energy they siphon off to cool the car off the charge current. It is surprising they are not powered separately with their own circuit by the charging station using AC Line Current while charging, they will still need to operate off the car’s power when mobile, but at least the inefficiency of converting the incoming AC to DC would only happen in the car, not the kiosk, while connected. Of course, that would add more connections to the charge plug connector.

Make ammonia out of seawater, it stores more hydrogen than liquid hydrogen but is far easier to store and transport and can be used (with modification) in a standard ICE engine or heated to release the hydrogen and then put it through a fuel cell...or buy a battery electric car with its legacy of dirty mining for the rare earth elements needed to make it...and on top of it all, we need less seawater.

Stan Meyer’s Car With a Water-Powered Engine Meyer’s invention promised a revolution in the automotive industry. It worked through an electric water fuel cell, which divided any kind of water - including salt water - into its fundamental elements of hydrogen and oxygen, by utilizing a process far simpler than the electrolysis method.

[@rdlynes]

The fact is there are more than enough opportunities for both hydrogen fuel cells and batteries. When you look at the total life cost for batteries on the pre manufacturing side sourcing materials it's a pretty dirty process and very inefficient, Not to mention the end of life which nobody has come up with a good viable option for batteries or solar panels. The production of clean hydrogen to be used in fuel cell applications is certainly where most of the research has been applied and you can easily take a microwave plasma torch gas application process using feedstock like coal or municipal solid waste is instead of putting it in landfills, you can put it through the gasification Process reform the syngas into pure hydrogen. Yes you have to truck it to the stations but you have to do that with gasoline and diesel as well. There are applications available for generating hydrogen on site using either of the natural gas or my preference would be water electrolysis. You can also use below ground gasification at the mining sites for coal to clean the entire process up. This is being done all over the world but here in the United States. Once you have the hydrogen there's very little difference between a fuel cells and a battery both are producing electricity for an end use. There is no excuse today builders that are planning master communityies of 300 or more homes could easily put the gas piping in the ground from a small waste2energy plant on site and each home could have its own fuel cell hydrogen generator that could run everything that the house needs as well as charging their electric car. I love just about everything that Elin Musk does but I must argue against his philosophy on hydrogen and fuel cells. There are a few companies that are working on getting the production cost down down to between 2 cents and 8 cents per kilogram of hydrogen which makes it more than competitive. When you look at the energy and pollutants used in mining battery and solar cell materials in the preproduction process as well as end of life you will see that it is much dirtier than using pure hydrogen, No one can argue that the only output from using hydrogen is water and oxygen.

[@jaytang3972]

The medals in batteries aren't really consumed. Why don't you just recycle them? You just need to collect enough retired battery for economy of scale to kick in. When electric car batteries retire you will get that economy of scale

[@jaytang3972]

And you are ignoring how incredibly inefficient H2 is as a energy storage medium. Let's say you begin with 100 units of energy in electricity, then you break up the H2O to create those H2, and then you convert it back into electricity to use them. You end up with maybe 30 units of electricity for use. Which means you need to product 3x more electricity for the same amount of end electricity, so you create 3x the pollution producing them. It's simply inefficient. Unlike natural gas,H2 doesn't transport well in pipes at all, they really like to leak out of pipes, they make medals in pipes brittle. That's why even with reinforced tanks, Rockets fill the tanks with Nitrogen first, and only fill the cryogenic hydrogen right before launch. They don't like to stay in tank or pipes.

[@rdlynes]

@@jaytang3972 If 50% of the cars on the road just in the US were to plug in our grid would fail. Not to mention this does not include trucks or other transportation systems. Even in this case, we would have to fire up coal-burning plans to take that load. On the battery side, we don't currently have a process or facilities for recycling battery materials at end-of-life, we also don't have the raw materials to electrify our transportation systems. This will take more than one source for this mode of transportation. If we did not put current levels of CO2 into the environment we would be facing much worse issues to our planet and standards of living.

[@colingenge9999]

We could make hydrogen at home using electrolysis but the equipment is very expensive and we only wind up getting 25% of the energy back that we put into it in the first place so that conclusion is just start a new battery and get 90% of it back. A whole lot cheaper all the way around.

[@TheControlPhilosopher]

Ammonia seems to be a better idea. Liquid NH3 is easily made, safer & cheaper to store & handle than Liquid H2. Even better is that it carries nearly 45% more Hydrogen than Liquid Hydrogen itself, for a given volume. Ammonia easily splits at 500-600°C to yield hydrogen. Gas-turbines have run at high efficiency & no emissions when fed with ammonia. And there are fuel cells under development that consume NH3 directly. So the hydrogen economy when it dawns may indeed See a huge role for NH3.

How are difficult and expensive would it be to have personal size, Solar powered, green hydrogen generators?

Did I miss the part about hydrogen powered internal combustion engines? No fuel cells required. No lithium or other rare earth materials required. It may not make sense for cars but there are companies starting to produce internal combustion engines to displace diesel in farm and construction equipment. They plan to create green hydrogen from wind and solar. Since these are off road vehicles, they don’t need hydrogen refueling stations the way cars do. Batteries can’t supply enough power for these applications but hydrogen could. What if farmers could generate their own hydrogen from wind right on their farms or at a local co-op?

[@peterazlac1739]

JCB is now selling a hydrogen-fueled contractor plant that uses a conventional diesel engine with the top half replaced to include a high-pressure boost turbine. This means they have not had to change much of their engine manufacturing plant and users do not need to train mechanics in a new technology. The lightweight carbon fiber fuel tanks allow a day's worth of fuel to be carried by each type of equipment from loaders to excavators and be refilled from a mobile bowser. The engines are already being produced in the UK and India pointing the direction in which industry will go and it will not involve batteries that go on fire. A recent technical review of wind farms over a ten-year cycle has demonstrated that they are not fit for purpose bringing instability to the grid and requiring the same power from dispatchable backup and a recent auction in the UK did not have any takers to build new wind farms. So the EV will end up in a small market niche of persons living in southern climes with large houses that have enough roof space to produce the power they need for their home and EV but for Joe Blow it is a wash since he cannot afford the second-hand price of EVs that need a new battery and the cost of charging them is now exorbitant.

Hydrogen generation efficiency in not that important of an issue when the energy source includes solar and wind renewables on live grids, since when they are generating excess capacity it is normally not stored (for example, wind turbines are usually shut down during high winds when the power is not needed). This excess energy could be stored via hydrogen generation, and turbines on the grid could burn it when needed. Added renewable capacity could generate more hydrogen, eventually obviating coal and natural gas on power grids. Concerning ground transportation, mass transit in the form of electric trains/subways/trolleys is far more power efficient than cars/trucks, because the mass moved per individual is far lower, partially because electric rail systems do not tote their energy sources. Electric rail systems are also cheaper to maintain than roads, which are big polluters due to relatively frequent surface replacement requiring poured concrete. Cars/trucks should be de-emphasized regardless of their energy sources. They are a waste of energy to run, build, and dispose of.

[@hanswitvliet8188]

I’m afraid you must some import points.. You mentioned that there is a all spanning electricity network. Well, after they discovered natural gas here, our government took care that 99,6% of all buildings are connected to our national gas network, which can be used for hydrogen (at comparable pressure) Increase pressure, to 750 atmosphere, for vehicles, can be done everywhere, at any service station. Using it for personal, private cars, is doable, though still in its infancy. On national tv it was shown that an entrepreneur had a fuel cell installed in his Tesla model S, enlarging it’s operational range over 1200km. Grey-hydrogen is a no-go: check the Orkney islands, where a surplus of electricity is used for producing H2. And, especially for home usage, is hydrogen fuel cells ideal, as they produce both electricity and heat. So, for everything there’s a time and place. The time for diesel is simple over and done.

[@atrunkfield]

As they develop new ways of extracting hydrogen, particularly low impact, carbon neutral ways, then developing the infrastructure might be as simple as having a hydrogen generator on-site at each fuel station - then it becomes a no brainer, hydrogen electric vehicles should be the mainstream.
