  1. Sounds easily solvable if you have the free time and a little bit of money to buy a place to work on it till it's ready

    using free solar maybe
    using algae or grass to make

    maybe methane

    to ghost da opps: (to ghost da opps)
    (for clarification)5
    "to quote a friend of mine"

    and hydrogen using free solar and free carbon capture to forge a real diamond pickaxe!
    and free plastic alternatives and the electric scooter is kind of a hidden camera but I don't get to hug anyone but I don't get to hug anyone but I don't get to hug anyone but I don't get to hug anyone

  2. I don't think hydrogen will ever get off the ground in the real world.
    It's like fusion power – always "on the horizon" but it never arrives.
    I think that a LOT more effort should instead be put into energy and products from sewage. I'd love to see an episode on that, Matt.
    Think of it – the "feedstock" is effectively infinite and basically free, and it's already piped to where energy from it would be used – cities.
    It is often not difficult to add a sewage biogas plant to an existing wastewater plant.
    The solid waste could be used as feedstock for a bio-refinery, producing fuels and other much-needed chemicals.
    It's a win-win all round – you make use of a waste product, generate electricity and create fuels and chemicals.

  3. Norway, which is primarily powered by renewable energy, is apparently very keen on getting into hydrogen production, but needs more interest in Europe to push forward with it.

  4. ‘The result changes the efficiency from ~75% to 95%’.
    And there I was thinking that the efficiency of creating hydrogen through electrolyses was currently more around 33% than 75%.
    Could someone explain the discrepancy there?
    For example, perhaps that low figure I had in mind was the whole current hydrogen production mix of methods combined not electrolysis…
    Perhaps that low figure is the efficiency of hydrogen electrolyses with the current energy mix in mind?
    I don’t know, but I have a vivid memory of learning on several occasions that hydrogen through electrolyses is like 40% efficient at best.
    ‘You can drive 3 battery EVs with the same energy you can drive one H2 FCEV’!
    Are fuel cells more the inefficiency culprit than the electrolysis is??
    I’m confusing myself. Helllllp! 😅

  5. How difficult is it to store Hydrogen? I would assume that for just the issue of space, it would need to be stored in a liquid phase; and the pesky Laws of Thermodynamics make easy maintenance of liquid H a virtual impossibility, as it would require a huge amount of energy over time keeping it cold enough. Also, it is the lightest element and kind of just slips out of whatever it's being carried in, floats upward and out to outer space.
    Those are some questions I have. Let us see how those are addressed in this video. I'm sure Matt knows all of this, but he's not trying to make long-form documentaries and TIME (I stopped the video at ~1:04) is an issue there.

  6. ….NOPE…ECOLOGY MUSTVE BEEN DEPRIOTIZED….IN FAVOR OF… CUTTING COSTS ………BECAUSE FOSSIL FUELS ARE BECOMING SCARCE…….ISNT that

    ……..AND….WELL,AS FOR MYSELF……I'M VERY ANTSY TO…….LIKE…..SEE WHAT AUSTRALIAN SOLAR PANELS ARE CAPABLE OF…..TO LIKE…..BYPASS EFFECIENCY LOSSES……..

    …ABOUT ATTACHING ELECTROLYZERS TO WIND TURBINES== WHY ONLY NOW ……..

    …….BUT…still…….WHAT'S ABOUT DEGRADING OF ELECTROLYZERS AND KINDA TRANSPORTATION ISSUES THRU PIPELINES…….

    ……U KNOW,IF ENERGY WILL COST LIKE 0,00001$/KWH TO everyone THANKS TO RENEWABLES……THAT'LL IMPROVE everyone's QUALITY OF LIFE DRASTICALLY

  7. This is cool. A few years ago, I built my own hydrogen electrolysis device. It works from a 16v li-ion battery made from salvaged laptop battery 18650 cells. The hydrogen and oxygen are allowed to mix in the single gas chamber. Then, it runs through 2 separate spark arrestors followed by some flexible, stainless steel gas hose before running to a mini torch head. It is similar to a small acetylene cutting torch. It can cut through sheet metal. The best part is, I don't have to buy oxygen and acetylene, I just need a charged battery and water.

  8. I am a older man who worked heavy equipment diesel repairs. I am all about hydrogen power and have made some of those little cubes that produce hydrogen. I had small engines running just fine on it. My issue is windmills kill too many birds. In fact when you look at insects as a problem, killing one bird is a problem.

  9. You should have stopped several minutes in. Improving efficiency from 75 to 95 % is barely going to dent the fact that the battery path is three times more efficient. There may be a route for some liquid H but only for niche applications.

  10. How much water is lost in this process?

    I don’t think it is wise depleting the primary compound required for life as we know it because we want to play on our cellphones.

    Unless they can guarantee a net zero loss of water from the electrolysis / combustion reaction – I don’t think it is a viable process.

    Hydrogen is everywhere. Why are we extracting if from the most valuable resource on the planet?

    Also, nuclear power is still a green option. All we need to do is find a way to get rid of the waste and if need be, we can just hurtle it to the sun.

  11. Stop it. There is no such thing as green energy. There is no free ride. Not even solar. It takes more energy in fossil fuel usage to MAKE the hydrogen than the energy you will get out of it…meaning it is LESS green than just burning the fuel itself for energy. Enough with the propaganda. If you passed a high school science class…you know why this is true, and why none of this propaganda can EVER work. It breaks every law of thermodynamics. For all of you who failed high school science………..just stop falling for this. There is no such thing as green energy. Just as there is no such thing as perpetual motion.

  12. just not tell me that we will use existing nat gas distribution system for H2 ! Keep in mind: black steel becomes brittle in H2 presence under pressure.

  13. No future for H2 as green fuel, without governments paying the cost no companies are going to build a whole new infrastructure for H2. H2 is only useful now as industrial reactant. The world is overproducing natural gas now and the price will be dropping next year as the LNG produced will be more than demand, look at futures markets and you can see the long term price dropping.
