      Calling this thing anything other than an inefficient science experiment is disingenuous. The amount of power required to electrolyze any useful amount of hydrogen is massive (especially considering the output of a solar array). The tiny solar cell and limited efficiency of it means there is not a chance in hell this device creates enough hydrogen to usefully do ANYTHING productive.
      Fact: people have been making these since Radio shack was still around, hooking up their solar panels to a transformer then dipping electodes in water. This, isnt remotely a new invention nor is it anything that will ever be useful to adults. Children might learn something about physics from it, but this kind of tech wont be powering anything soon.
      Solar is already too inefficient, and electrolysis loses the vast majority of that energy just to break the atomic bonds and give you the hydrogen.
      the sad truth is if you wanted to drive an electric motor, you'd get more usable energy just hooking the solar cell straight to your battery pack than adding the step of electrolysis.

      No matter how you store the H2, the danger for local storage at home is problematic regardless of the pressure since H2 is more explosive than natural gas. Even storing gasoline in a fuel can is generally not recommended let alone H2 in a compressed tank that is prone to H2 embrittlement. H2 is just a tough gas to use safely especially in a domestic household setting.

    When comparing a fuel cell vehicle to a battery electric vehicle, please remember: fuel cells produce DC current just like a battery. So you will need an inverter for either of them, to power your home or your EV's AC induction motor (lightest, most efficient and most flexible type so commonly used in EVs).
    Most batteries can return 85 - 90% of the energy you put in. If you can get the hydrolyzer up to 71% efficiency, and the fuel cell up to a similar level of efficiency, you will get about ½ of your energy input back out (√½ ≈ 0.71). If they can get the hydrolyzer and the fuel cell, each, up to 90% efficiency, you'll get about 81% of your energy input back out again (0.9 × 0.9 = 0.81). That's getting competitive with a battery. 95% efficiency on each would make it fully competitive.
    Solhyd is claiming they can hit that with their hydrolyzer. But fuel cells ... not there. There are high-efficiency fuel cells but they use a lot of platinum, which makes them hideously expensive (figure about $250k for 25 kW output; 25 kW is about 33⅓ horsepower). There are cheaper ones, based on nickel, which are nowhere near their level of efficiency (~40%). 0.9 × 0.4 = 0.36 or 36% round-trip efficiency, which is still less than half of a battery.
    WRT storing hydrogen: there are carbon-wrapped tanks which can take 700 bar (over 10k psi) but you will need to expend a LOT of energy on the pumps to put it in there. And it will still take a larger volume, compared to gasoline.
    Metal hydrides typically only need about 500 psi (lower pumping losses) but fueling is exothermic and expelling the fuel is endothermic. Rodger Billings drove a hydrogen-fueled Cadillac in Jimmy Carter's inauguration parade, with the hydrogen stored in metal hydrides. The fuel tanks had tubes running through them; engine exhaust went through the tubes when the engine was running (providing heat for the endothermic release) and cool air was pumped through the tubes when fueling (providing cooling during the exothermic fueling). The big problem is that metal hydride powders are very heavy; you're lucky if 5% of your total stored mass is hydrogen.
    1 kg of hydrogen has about the same energy content as 1 gallon of gasoline. That's 20 kg / 44 pounds of mass to carry the equivalent of 1 gallon of gasoline. Gasoline weighs about 6.5 pounds / gallon and you don't need a 500 psi-rated tank to hold it.
    You talk about a Solhyd panel making 250 liters of H₂ / day. I'm assuming you mean 250 liters at STP; you did mention it was low pressure. 1 kg of H₂ is about 12k liters at STP. You would need about 48 such panels to make the hydrogen energy equivalent of 1 gallon of gasoline per day. If they can do that for 30 years ... the per-kg cost might be reasonable.
    Hydrogen makes sense in only 2 cases:
    1 - You need to store the energy for weeks or months at a time. Batteries are good for a few days, maybe a week, but not for longer timespans. The Apollo capsules used hydrogen / oxygen fuel cells to carry energy for an 11-12 day mission, providing heat and potable water as byproducts. Battery tech of the time was nowhere close to that storage capacity and the byproducts were useful. Artemis will use a lot of solar panels and some batteries; they won't be hauling all of their energy when they blast off the pad. Apollo had no choice; solar tech wasn't ready, back then, either.
    2 - You need to transfer the energy much faster. If you are refueling a vehicle and need to refuel in a handful of minutes, rather than having a hour, hydrogen makes some sense. An Over-The-Road semi can store liquid hydrogen (LH2) for 500 miles and you can refuel it in minutes. A battery-electric semi ... good luck getting the charging time for 500 miles down under an hour. A driver is going to want to spend as much of their time as possible in motion (they get paid by the mile, not by the hour) so many heavy-truck manufacturers are actively working on hydrogen fuel cell rigs, running on LH2. Ditto for electric airplanes. They're hoping that, if they build the demand, the supply / infrastructure will come.
    There are three "miracles" needed before we can transition to a hydrogen economy: the cost of production needs to come down, the cost of storage needs to come down and the cost of usage needs to come down. The Solhyd panel appears to be working on the first one. All three are making evolutionary gains but ... I think we're still decades away from a hydrogen economy being realistic.

      Concerning semi-tractor trailer trucks…remember there are laws in the USA limiting the time a driver can spend behind the wheel. So recharging the batteries in under a hour is not an issue. After 6 hours of sleep the driver will awaken to a fully charged vehicle and be back on his or her route again.

    • @HeyChickens
      @HeyChickens Рік тому

      I think battery charging time issues could be totally resolved by having a system of battery swap-outs. Each vehicle would have a yearly subscription to a battery swap-out service. The battery packs would be charged up by the swap-out service, and the driver would simply switch out battery packs. This could be done much faster than even standard fuel fill-ups! The swap-out service would not have to worry about their batteries being stolen any more than a gas station would worry about their barbecue propane tanks getting stolen. The customer would only have one battery pack at any moment anyways.

    To drive 1 mile with a hydrogen fuel cell car, you need about 20 grammes of hydrogen. This costs at least 1 kWh to make. To store the generated hydrogen in the tank, costs another 20% energy, so that makes 1,2 kWh per mile. A solar panel with 400 Wp takes 3-4 hours to make this amount of energy around noon. On a full day the panel will be making about 2,5 kWh. Suppose you have 20 of these panels and it's sunny summer day. Then you can generate 50 kWh - which enough for 40 miles - for a big roof with 20 panels. Just barely 2 miles per panel, per sunny summer's day. Btw. a BEV will do with 1/5 th of the energy, much more feasible, and safe. When you would burn hydrogen in a combustion engine, you'll need 3 times more than for a fuel cell car. No way that you can provide your own hydrogen for that.

      Yep that is what will be needed for seasonal storage. A large array that powers the house, charges the batteries to run the house and charge the vehicles at night, and provides seasonal storage for the higher latitude countries when there is plenty of sun in the summer. The H2 would be best stored as ammonia for use in the winter when solar is very weak or nonexistent for months at a time. A home would size their NH3 storage tanks based on how long and severe their winters are. Also with a freezing point of -70 C the tanks won't need very much insulation. Or they can just run their home off of RNG in the winter 😅. These also have the huge benefit of not using ground water to make H2 to preserve our fresh water resources.

      It makes sense to develop for heavy freight industries like rail, but especially shipping - and also notably lightweight air transport too such as ultralight planes and drones. Having on-harbor production facilities to utilize wave, wind, and solar energy to not just power the grid, but to also use excess energy to directly produce store the energy as hydrogen, and then fuel cargo ships directly as they dock and load/unload. You also have a vast abundance of hydro right on location, and pretty much all freight harbors of the future will become energy hubs through direct grid link, as well as hydrogen production.
      There is already a multi-billion investment in Power-to-X in Nordic countries to become the main European supplier of green hydrogen in the coming decade, specifically utilizing these methods - even going as far as building a massive artificial island in the north sea with the exclusive purpose of creating this infrastructure at a multinational grid level.

    • @notanytimenow
      @notanytimenow 20 днів тому

      One of the big benefits over straight batteries for hydrogen is refueling speed. For vehicles (trucks, trains, planes, maybe boats) the amount of electricity required to be transferred into the vehicle at refueling stops is too damn high to cost effectively charge in more ways than one. Commercial vehicle usage pattern exceeds the average consumer car travel time per day, and every minute waiting for charge up is a minute the commercial vehicle can’t be used for transport.
      Hydrogen can be green way to solve it, but so can flywheels, or other chemicals, or dedicated charging on the go hardware/tugs (think trolleys/buses that connect up to overhead electrified lines) for stretches of highways or whatever the byway is that serves the mode of transport.
      You don’t even need to go fully into one of the refuel strategies as the only way to store energy. You can put in modular refuel/generator to primarily a battery powered truck that allows for fast refuel and slowly recharges on the go perhaps.
      My favorite mix would be using batteries as flywheel weights. You spin up the weight at refueling stops, then slowly covert that to stored battery energy as traveling down the road/rail/air. Vibrating flywheels because of road bumps would kinda become a nightmare maintenance liability I suspect.

And particularly not for home use! I don't want to live in a building, where you always have to fear it blows up, because some vibration or aging of material has let to a leak!

    Correction, current fuel cells are something like 70-80% efficient. The DoE's numbers are for the entire round trip efficiencies (Even bEVs are something like 60-70% efficient according to the same metrics). BEVs are still far better in my opinion (a 20% gap is massive especially when you consider it's closer to 80-90% efficient when you get the power directly from your own solar systems) but hydrogen isn't a "dead option." In addition, the weight aspect (there's currently something like a 8:1 ratio for storage of hydrogen) is kinda glossed over. That still makes it "better" weight to energy compared to a bEV, but it's not as simple as taking the raw weight of hydrogen. That being said, I doubt these panels will be "coming to your home." Fuel cells are kinda expensive enough where I'm pretty sure for the average home a 5-10kWh sodium ion power wall will be cheaper. This seems more likely to be used at scale in places where there's a lot of land and a lot of sunlight on an industrial scale. These would likely go to the consumer hydrogen market for bigger vehicles (long haul trucks, aeroplanes etc which need the energy density) rather than the consumer market which will do just fine with BEVs.

You got to get the computer to accept the hydrogen into the system, and you have to have a bigger alternator, like 240 amps. 140 amps to run the car and 100 amps to run the alternator, or run two alternators, which ever is best. I went from 26 mpg, to 53 mpg, of course I only did that one time about 10 years ago. I haven't done much sense. I gave up on it.

    Almost every time I see someone calculate the cost of a system amortized over a long time span, they neglect the "opportunity cost" of the initial investment. If you spend, for example, $16,000 putting 20 of these panels on your roof, and expect to use then for 30 years, you should add to the cost over that lifetime the money the $16,000 could have earned if invested somewhere.
    It's not unreasonable to say the $16,000 could be invested somewhere that earned 6% per year. That's close to $1,000 per year in lost returns that you could have earned if you passed on installing the panels.
    To make the math simpler, let's call that $50/year per panel.
    Each panel makes 250 liters per day, they say. 91,250 liters per year. At standard atmospheric pressure and temperature, hydrogen gas is about 0.083 g/L. That works out to about 7.5 kg per panel per year. Divide the $800 cost of the panel by a 30 year life, and the cost per year is $27. Add the $50 in opportunity cost, and the total cost is $77/year. Hmmm. That means the hydrogen is actually costing 0ver $10 per kg.
    And that neglect the cost of the compressors and tanks that would be needed in a practical set up.
    The math doesn't work.

    Everyone considering hydrogen as a fuel source should do this first:
    1. Do the plumbing for a "on-demand" water heater, including gas lines. (if you actually do this, do the work, then have it checked by a professional to see how well you did.)
    2. Replace an oil seal on any internal combustion engine of your choice.
    These will give you a visceral understanding of the concept of making a good seal.
    Now consider that hydrogen gas causes embrittlement of metals (and subsequent failure) and that pipe junctions are extremely difficult to seal (for us average folk)
    This makes hydrogen a non-starter.
    Though some solar electronics can be complicated, they are sold as easily replaceable modules that anyone can learn how to do.
    Large profit incentives for battery technology will insure that batteries will become cheaper, safer and lighter over time.

    Hiydrogen has high energy per unit weight, but a very low energy density by volume at room temperature and atmospheric pressure. So the only way to pack enough hydrogen in a vehicle to get a reasonable range means either extremely high pressures or ultracold temperatures, both of which use up more energy.
    Storing electricity via water electrolysis, compressiion for storage, and fuel cell has an overall efficiency of about 27%. Storing electricity via charger and batteries is 85% efficient. So, it needs 3x more solar panels, and with the cost of the electrolyzer and hydrogen storage, it will cost more than the equivalent grid tied solar system with battery storage.

    In cold climates, like here in Norway, the efficiency by using hydrogen in a fuel cell is higher. We can use the waste heat for heating 1/2 of the year. Storing H2 for winter use could be interesting if the prices on fuel cells and storage goes down. Most norwegian homes are heated by heat pumps, so about 150-300kg H2 would meet demand for charging cars and running the house in the middle of the winter, 2-3 months. We pay most for electricity in the winter.

    First, thank you for continuing to produce good videos about new hydrogen technology, and for exploring the potential for using hydrogen as an energy source in the future. Everybody else, for some reason, seems to want to just put it down and ignore it.
    You say that hydrogen is very energy dense, then you say it has very low energy density. Of course you mean that it has high mass energy density, but low volumetric energy density. You should use those more specific terms because people need to start understanding energy density in both ways, since both are important. Also, you give the mass energy density without the storage container included, but since it requires heavy storage tanks, you should point that out immediately and give the adjusted mass energy density, including storage tanks. And then you talk about the amount of energy required to produce hydrogen as if that’s a problem, but in fact, it is exactly that reason why it does indeed have a high mass energy density. Put a lot of energy in to it to get a lot of energy out, energy is conserved. We would like to have to put even more energy in to produce it. The important factor is the efficiency of producing it, and the efficiency of extracting the energy back out again. Compare that to the efficiency of charging a battery and the efficiency of draining a battery. And compare the total volume of batteries required to store enough energy to power 1 million homes for three weeks, to the volume of hydrogen storage tanks required for the same thing. And, of course, compare the cost of the two systems also.
    Your focus is on residential and automobile use of hydrogen. But it’s pretty clear that hydrogen will definitely be used for applications involving heavy machinery that uses a tremendous amount of power, such as large long-distance trucks, mining vehicles, trains, maybe airplanes, perhaps involved in various industrial processes, like steel manufacturing. To that end, this hydrogen panel may make a great deal of sense for producing the needed hydrogen using large hydrogen solar farms, rather than using grid electricity along with traditional electrolyzers.
    I’m wondering about residential small scale infrastructure. Why not share hydrogen collection and concentration facilities among an entire block or two of houses? It’s not unheard of to have such neighborhood infrastructure. I have a box down the street that contains stuff for my neighborhood’s fiber optic cable system. Also down the street is a large transformer that steps down electricity for use in the neighborhood. Up the street is a large water storage tank. Under the street is a large sewage collection system, and a friend has a sewage pump station down the street from him.

    Might be an interesting way to dehumidify indoor air and save money on air-conditioning in humid climates.
    A problem with moist air when cooled is that as it condenses it gives off lots of heat (latent heat of condensation) with each gram of water that's condensed, releasing that heat to the airconditioner coils forcing you to run your airconditioner more. If you reduce the amount of water in the air, you lower the temperaure at which it condenses and saves energy to cool your home.
    But it takes energy to turn it into hydrogen? Yes but apparently that's 95% efficent and the energy is stored chemically, not lost. Adittional to using it to run a car, one can use it with a fuel cell for backup power for their home.
    Antidotally, my central air conditioner condenses about 10 gallons of water a day during the hot days of summer. It would be phenomenal if that could be reduced in half, Turning the other 5 gallons of water into about 4.63 pounds of hydrogen and 37.06 pounds of oxygen.
    Maybe releasing some of oxygen into the home might improve the home's air quality or may benefit oxygen concentrators for those who need them.

  • @chris1k23

    Thanks for your quality videos. Couple of things though :
    - hydrogen is no energy source, just as a battery is no energy source; both are just storage methods.
    - comparison is incomplete: the whole system should be considered, fuel cells require mining too, although a lot less I guess.
    - comparison should include complexity: solar => electricity => hydrogen => (compression =>) storage => fuel-cell => electricity, compared to solar => electriciy => storage (battery) => electricity
    - Complexity again but on car level: a hydrogen car is essentially a complete BEV with a very small battery + the hydrogen-tank / fuel-cell system on top of it => very complex
    I'm really not convinced hydrogen will ever really make sense in cars, or even if so, it's too late, BEVs have won. So the solution for these solar panels should rather focus on storage, mainly seasonal storage, but flow-batteries are probably the better solution for this use-case. And from a global energy production versus need perspective, in the context of the transition to clean energy, efficiency is top priority over comfort which in most cases range is. Range is mostly a psychological problem => the rational solution still is BEVs.

A large insulated tank of sand would make a decent thermal battery for cheap. You could also use a phase change material to store more energy without a huge swing in temperature. A Stirling engine can convert a temperature difference to electricity (and also the reverse) but using heat for heating is more efficient. It might make sense to have a mix of PV panels and thermal solar panels and use both thermal and electric batteries combined with the Stirling engine for conversion. A computer program could intake all relevant information and manage the system in a smart way converting if and when it makes sense to do so.

It would also be fed from home electric (solar, wind, central power, whatever). This means getting rid of carbon in non-urban areas (like most of Iowa). Roof decks would have solar and grass and streams (to maximize solar), just because we can - or they can simply be grass covered. Home electricity and internet would also come through roof deck system (or walls of roadway). On daily commute, car would stay in system in urban areas and drive you to transit and drive itself home - to return to pick you up from transit later. Nuclear power (made from recycled waste) would mostly power the system.

Solar Hydrogen is also promising, since with or without solar or sunlight, chemical reaction is used to produce the needed energy, similar to fusion of heat and the compound elements, that can make solarization and Hydrogen as protected.

    The problem with home solar is it only really works in the summer when you need the least power. So you need a system to store the excess energy in summer till you actually need it in the winter. Hydrogen has that potential, you can store H2 at high pressure without the need for compressors using metal hydrides at a density higher than liquid H2. In the winter you can use it directly in a gas boiler for heating or in a regular ICE generator for electricity. Also consider brewing/distilling alcohol in the summer to keep till winter. Burn it directly for heating or fueling a generator for electricity....

      If you are putting solar on you roof, and planning to use the harvested solar energy to cook with, you are throwing away a very large portion of the solar power. It would be much more economical in the long run to replace the gas cooktop with an induction cooktop. That utilizes the solar power to directly heat the pan - no wasted energy going past the pots and pans in the form of hot water vapor from the combustion of hydrogen.

    Besides cost and safety concerns, I'd say by far the biggest challenge with hydrogen is preventing hydrogen leakage. Hydrogen leakage is a serious concern, since it makes hydrogen actually contribute to global warming, because it slows or prevents methane breakdown in the lower atmosphere. Methane is an 80x more potent greenhouse gas than CO2 during its lifespan in the atmosphere. Managing hydrogen leakage to below 4.5% will be essential. This pretty much precludes decentral hydrogen production solutions like the one described in this video, since decentralised systems are uncontrollable. And governments will likely have no choice but to ban applications like these, since they will present a net contribution to global warming.
