    cost comes down with volume, and energy can be produced much more efficiently than we do now. Batteries, have been at a stand still in development since they went into wide use.

    This seems to omit costs of batteries. How long does a battery for a car last? What is the resale of a battery powered car when the battery has lost significant efficiency? What materials are used and what does to take to produce a battery capable of powering a modern automobile? if a battery begins with efficiency of 90%+- how long does it keep that efficiency before losing efficiency? How deep can you discharge a battery to maintain efficiency? What is the efficiency in freezing temperatures? The problems of creating and distributing hydrogen appear to be much the same as with oil products only cheaper. But if hydrogen could be produced on site say every 500 miles it wouldn't be much of a problem distributing up to 250 miles.As to the cost of hydrogen, as stations and other facilities along with R&D improving fuel cell/hydrogen costs will go down with economies of scale.

    Have you considered the cost and waste cycle of Lithium mining and battery production? Hydrogen is a clean production cycle with no waste assuming electrolysis via water and renewable energy. It is less efficient end to end now but has huge benefits with energy density and the weight to range factor. Hydrogen has alot of benefits and there are more drawbacks with batteries than are being reported here.

    I can conclude in one sentence from your video that hydrogen powered car is expensive. 2.2 cents per mile vs 17.7 cents . But I would definitely like to go for hydrogen powered car because extra 15 cents cost is worth it when you consider fast refueling , only 5 minutes . The extensive infrastructure would reduce the cost dramatically

    Hydrogen is pretty good. This is how u solve it. Use nuclear power plants as they have the best Co2 to KWph than any other form of energy. Yes even factoring in the mining and the recourse needed to build the plant. And use that electricity to make hydrogen.

    Well the problem is like the batteries degrade over time. It’s like having ur fuel tank get smaller and smaller over a period of 10 years. My laptop is about 4 -5 years old and it’s warning me to replace to battery soon. It also last about two hours a day compared to its 12 hours when I got it. Idk about you but the production of battery is very costly especially to the environment.

    everyone says you have to go to a pump to get hydrogen but you can make it your self and we can use solar panels to make hydrogen .

    • Milan Swoboda
      Milan Swoboda 2 days ago

      yes you could produce Hydrogen via Solar Panels but you also need to include the hydrogen production, compression, storage and filling equipment plus maintenance thereof.
      Furthermore you need to consider how much minimum daily H2 production is required to fill your needs and then look at the solar array and production equipment size to full fill those needs and the investment needed for such a system. It might be a very sobering experience for you.

    • Scot Fenn
      Scot Fenn Day ago

      @Milan Swoboda New technology is bringing the price of making pure hydrogen down. I can't remember the companies but there is a few of them working very hard at this aspect. I see HEV's much more attractive than direct EV's. All we need is hydrogen fuel infrastructure put in place. It's not very hard to do. Existing fuelling stations have plenty of room to add a hydrogen pump system.

    • Milan Swoboda
      Milan Swoboda 2 days ago

      is it coming down quickly? last time I looked un-subsidized compressed H2 cost actually went up some due to higher NG costs which is the main source for H2 production.
      Why would plugging an EV in rain be a serious problem? Charging equipment and components are well insulated and have fault protections integrated to avoid such accidents so chances of electrocution are very slim even in rain.

    everybody is doing it wrong, 100% electric or in this case 100% hydrogen.. just stop. theres a gasoline 3 seat ugly ass sports car that gets 1200 miles on 20 gallons of gas using a 96,000 rpm turbine to charge 2 massive electric motors but thats too damn expensive for now but a good idea none the less. instead what we need to look at now is a gasoline/HHO hybrid that uses a tank of water and through electrolysis creating HHO be injected into the engine with the fuel to significantly boost the mpg nearing or exceeding 100mpg depending on the type of vehicle and its purpose, and all at 90%-95% fuel burn far exceeding the strictest emissions standards. heres the thing, thats all at a 2 mason jars of water rigged up in the back all DIYed in older cars with originally shitty mpg not engines and vehicles specifically designed for it. right now this is the way to go and unlike natural gas its not exponentially toxic to the environment and all living things to produce. nor like the toxic environment created by mining materials for batteries and not to mention all the coal and natural gas burned by the plants to actually make all that electricity. hell even at 100% hydrogen take a look at Pakistan, they have converted nearly all of their diesels to run off 100% natural gas and getting better mpg than actual diesel. their vehicles are mostly all diesel because at one point diesel was much cheaper than gas and now most cant afford either. there was a few guys that actually did 100% HHO but where "suicided". one man actually got a patent and when he refused to sell to a big oil company he and his patent suddenly poofed. another made a conversion kit for any vehicle and had a 100% electrolysis buggy, he and his buggy and boxes of conversion kits suddenly poofed too. i think it was Indonesia but a guy made a 100% electrolysis motorbike that got insane mpg and he made a few videos like the others and the government paid him to shut up, i wonder if hes still alive. seriously the only reason electric cars exist is because big oil still makes a profit from crude oil for power plants and government and big oil can control peoples ability to travel by electricity. and that i bet you is the real reason behind the purposeful power outages in commiefornia, its a test run. solar you say? well its hooked to the grid so for the majority it cant be used during an outage. and in many places people are taxed and charged for the power their panels create connected to the grid or not. hell you didnt even mention the cost of batteries both to make them, buy them, and their toxic waste as their life span is rather short.

    I am working as an electric taxi driver. I can say -- the electric cars are just disaster. My car is Nissan Leaf. Its made in 2015. Not very old. But when I charge it full (it takes an hour with a FAST recharger) the meter shows you can drive 120 km. BUT its not true at all!!! Actually I can drive maximum 60 km (40 miles) when I am really careful and SLOW (30 mph); and only 30 km (20 miles) when I have to make somw longer and faster (50 mph) rides. So the batteries have lost more than 50% of their value within some years!!!

    Good video, but I was missing the production of Lithium batteries in the equation. It's a one time cost, but maybe there are estimates of how long a lithium car battery is used before it gets replaced to make it into a CO2/km cost. What's the expected recycling quota once the batteries lost too much capacity? 15 minutes is way to short for an in depth comparison. :)

    "Indigenous people in the lithium triangle worry that the high levels of water needed to produce lithium -- as much as half a million (500,000) gallons per ton (2,000 lbs) -- may cut into the already limited water supply"

    • udmbfck x
      udmbfck x 21 hour ago

      @Milan Swoboda Show me your source. Post it. Then tell me that it is not affecting the local indigenous population. Every time a new tech is created, someone, somewhere gets affected and all the while people buy into it because of the new exciting "benefit". Show me the link where the water is returned to the local people. Not only that, even though it appears that there is a few centuries worth of global lithium reserves, it cannot be scaled fast enough ("Hell No" says the 1st article below). In addition, consumer electric cars are only a FRACTION of the total energy used in Global Transportation, so yes, it will be way past out lifetimes and our children before the ICE will go extinct (see 2nd link): "Barely 2% of the world electricity is used by transportation [2], where most of this is made up by trains, trams, and trolley buses."

    • Milan Swoboda
      Milan Swoboda Day ago

      @udmbfck x you also cannot drink gasoline so ....? As for the 500k USgal per ton of lithium, the reports do not specify what the composition of that water is but it hint´s that it is mainly brine and that is something that is not safe for human consumption anyways. Evaporation of brine is a rather slow but profitable process however rising demand will make it worthwhile to use RO processing and using the concentrated effluent for evaporation which is significantly faster than evaporation with non concentrated brine plus getting RO filtered water as a byproduct that is safe for consumption so the 3 r's are nothing unheard of for lithium production either and use of the 3 r's will be expanded with public pressure and demand.

    • udmbfck x
      udmbfck x 2 days ago

      ​@Milan Swoboda Ah...your sensibilities were offended, therefore you resort to ironic name calling. But you probably don't know about the concept of recycling water, since transporting clean water inland and dirty water out is very expensive, as it is the case for fracking, for which there is a solution that re-uses flowback water (check first link). You haven't even been able to defend the position that I stated on the 500,000 gallons of water, in the middle of the Atacama Desert , to produce 2,000 lbs of lithium and the NEW situation it has created there, now you are basically saying it is all 'relative'. There is a lot more to this as infrastructure around electric cars needs further physical development, something we already have with ICE vehicles...... And the issue of reusing the water? Ask the indigenous people in the area and they'll tell you they cannot eat lithium batteries (Check second link).

    • Milan Swoboda
      Milan Swoboda 2 days ago

      @udmbfck xlol Oil only needs to be found once for drilling, aren't you a gem. Ever heard of water injection at oil fields? During petroleum refining water is also used for various operations e.g Hydro cracking, blowdown processing, sour water from acid removal,...etc. approx. 0.75 liters of water is used in the refining process to obtain a liter gasoline.
      Now if we go by your sentiment that Oil produces water then we can also say that lithium production from salt lake brine is water purification since the process desalinates water, right?
      No technology is really green if you look deeper and in more detail. Is mining for Lithium a dirty business, sure but that applies to pretty much all mining and is not limited to lithium for batteries so it is not a singular issue

    • udmbfck x
      udmbfck x 4 days ago

      @Milan Swoboda Oil only has to be found once for drilling to begin and water will be used, but once oil is discovered, water is also 'released' from the ground as a byproduct and therefore also 'produced' (see second link).
      Lithium also has some level of mining and other environmental impacts affecting local communities, not to mention the FACT that lithium, like oil, is also a FINITE resource in Nature......Not everything is rainbows and sunshine as the Media would like you to believe.

    Why not use entirely DC motors in cars? that can eliminate another conversion inefficiency.

    • Milan Swoboda
      Milan Swoboda 4 days ago

      brushed DC motors have efficiency issues and unwanted EMF, brushless DC motors, which are also used in EVs , are not so different than async .AC motors and still require drivers for speed control that chop up the DC voltage so there are also some unavoidable losses involved. It's a balancing act between cost and efficiency for manufacturers.

    So while my comment is old, you didnt cover the leakage loss of hydrogen tanks. Because hydrogen is so small, it can leak past seals and leak though the metal containers themselves. So even storing hydrogen, you lose energy. Much like batteries.

  • Sam tron

    What about the mining of cobalt and lithium?
    There are a ton of great reasons why hydrogen is better...
    We can absorb the inefficiencies with renewables...
    If you convert mining costs into inefficiencies automatically puts hydrogen in the lead...assuming both are using renewables...

    • Milan Swoboda
      Milan Swoboda 3 days ago

      @Sam tron quoted: " the energy in hydrocarbons comes from hydrogen"
      Nope it comes from both Hydrogen and from Carbon hence the name hydrocarbons. Which of the two provides more energy depends on the hydrocarbon type / composition. E.g. Gasoline has a mixture of C4 - C12 hydrocarbons and is by weight about 86% carbon and 13% Hydrogen remainder Oxygen. if you take the specific energy by weight for carbon and Hydrogen into consideration then the Carbon provides about 62% and Hydrogen about 38% of the energy in Gasoline.
      As for renewables and night time storage, well for one not all renewable energy is dependent on daylight and countries like Norway already show us what can be possible on the renewable energy front.
      Is power to gas something that can be used for excess renewable storage for peak demands? Absolutely but it is not the only player in town and in the end it will be a combination of storage techs with those that are the most cost effective / efficient getting more investments.
      That Japan is putting a lot of money into Hydrogen might be more driven by their current high dependency on imports of natural resources. Lets see how it will pan out for them down the road.

    • Sam tron

      @Milan Swoboda let's agree to disagree because you misunderstand everything I'm saying.
      The energy in HYDROcarbons? Comes from the hydrogen.
      Hydrogen can be made inefficiently with renewables.
      we cant power the world with renewables. We would need a battery the size of the moon to store enough energy for peak night time usage...
      WE CAN translate sun directly into a liquid/gaseous/portable state...that satisfies night time demand...that's why Japan is building a hydrogen economy...and selling us fucking battery technology...

    • Milan Swoboda
      Milan Swoboda 4 days ago

      first mining for materials for batteries are an issue for you and then you say inefficiencies can be absorbed with renewables. Sounds like hypocrisy to me since more than double the renewable energy is needed for H2 production so more materials for the renewable harvesting equipment is needed and also need to build the H2 production and FC systems or do the materials for this stuff just apear out of thin air?

    The problem with hydrogen is that it is more expensive vs pure electrical energy. However, hydrogen is leagues ahead of battery in city environments. Who here lives in an X story appartment with limited to no access to even a normal outlet at street level, much less a high voltage one needed for quick charge. I for one prefer to spend more $$$ on a full tank of gas than to spend an eon searching for a street level outlet and another one to recharge

  • tony germin

    What you have missed is that the total CO2 production in use and manufacture of Batteries is Huge, I don't know the number but you should provide that number in your video. After you factor in the cost of C02 in making the renewable energy and the C02 cost of making the fuel cell. The operation of combustion or conversion to power in Hydrogen is a "0" carbon emitter. Not so for batteries . Not to mention that you are depleting the natural resources required to make the batteries which at the moment are not recyclable. On a large scale Lithium used to make batteries now, would be the equivalent of the oil economy Now. Hydrogen is the most abundant element on earth and the universe. Hydrogen burning in any form produces Water a resource that we need to live. Any other chemical reaction causes toxic effects and pollutes the world. Factor that in Please in your comparison.

    Just a note for those considering carbon emissions (which I consider silly since through most of the past several million years CO2 levels were over 2.5 times HIGHER than current levels per ice cores and the geological record)... the USA has reduced its carbon dioxide emissions over the past 2-3 years back to 1992 levels, whereas most other countries, including those which are still in the Kyoto CO2 reduction agreement, have increased their CO2 emissions.

    • Milan Swoboda

      So with 1992 level emissions the USA is still #2 for total CO2 emissions and #3 for CO2 emissions per capita and I guess now they are working on becoming #1 again and be proud of it. Sure there was high CO2 level for a long long time in earth history at more than 20 Mio years ago but lifeforms back during that time had been microbial life that was adapted to those CO2 levels without human life in the picture for a long long time thereafter. You should be send back to these high CO2 level periods and see how long you'd survive if time travel to the past would be possible ;)

      a FCEV is already a hydrogen-electric hybrid with a battery pack however the batteries main purpose is for regenerative braking to improve efficiency and is too small for even short trips. It would be possible to install a battery pack that is larger for average daily trips similar to PHEVs but that would mean higher cost, more weight and space issues since the FC system alone is occupying a lot of space .

Other BEVs also use advanced battery management systems but not always active thermal management but they also may use LiIon chemistry variations that have a higher cyclic and calendar life so a direct comparison to your Laptop cannot be applied. As for Fuel cells, well they also degrade with use especially the Catalyst within which is Platinum as well has the membrane. Toyota lists a 75K km replacement of the FC Ion exchanger element in their service manual but up until now have not seen data on cost for that.

    The Truth about Electric Vehicles is that their high-performance batteries require lithium, and over half of the global reserves of automotive-grade lithium have already been consumed by the cell phone industry, and now the automobile industry is competing for the remaining lithium reserves -- which requires destroying some of the Earth's remaining ecosystems in the process. While the video provides an excellent technical comparison, it fails to mention that lithium is not a sustainable, ecologically acceptable or safe alternatives to using hydrogen fuel cell systems in vehicles. The video also failed to mention that the high-efficiency numbers for electric battery systems also degrade with every charge, as anyone who uses a cell for very long phone knows. This is why they must replaced, which is also a highly-significant cost factor that was not mentioned. It is important to note that when the primordial proteins on the Earth were initially extracting the hydrogen they needed for metabolism from hydrocarbon molecules in the primordial soup, with a conversion efficiency of approximately 40 percent. But because the hydrocarbons were non-renewable, they were rapidly being consumed by the exponentially-increasing numbers of proteins and other bacteria and microbes they created were obviously aware they were heading into a mass-extinction event. And given proteins are the masters of molecular biology and transhydrogenation in every living organism, from viruses to humans, they created a new complex molecule called chlorophyll, which allowed the proteins to use specific wavelengths of sunlight to separate the hydrogen from the oxygen in water molecules, and while the efficiency was only about one percent, IT WAS SUSTAINABLE, and the protein's were able to survive and prosper for another three billion years. Although the future of proteins is once again in doubt, because they are now being mass-murdered and dissolved by oil-based hydrocarbons like gasoline into super-sticky amyloid plaques, which Wikipedia reports are now known to be at the molecular heart of dozens of terrible diseases, including cancer, Alzheimer's in adults and Autism in children, given babies are now born with these dreaded amyloid plaques in their brains and bodies. So the lesson is simple: It's not efficiency that is important, it is sustainability -- which means living in harmony with the Earth's protein-based life-support systems and species. And as the proteins knew very well, the key to survival and sustainability was hydrogen, the most abundant element in the Universe. -HB

      Please explain to me what "automotive grade Lithium" is and why it is used in consumer electronics like cell phones? Shouldn't the latter use "consumer grade" instead of automotive grade" lithium?
      Furthermore please show me actual trustworthy data that support your claim of the over half of the global reserves having been consumed by the cell phone industry.

    The market want cars that are lighter and more rigid and affordable atvthe same time.That requires some expensive alloys.
    I wonder if we are getting those alloys cheap from heavily polluting sources like China therefore negating any emissions saved by better fuel economy.
