    "Ricing" as a verb means something very different, I think, but I can't remember what.

    I guess I'll never know.

    There's a cooking implement called "ricer" that's basically like a big garlic press with rice grain diameter holes. Using it is called "ricing" and you use it on boiled potatoes when mashing would produce the wrong texture.

    There's also ricin, the very deadly toxin.

    Companies doing hydrogen fuel cell shit are getting a little boost from a recent scientific breakthrough: a stable, reusable, non-explosive polymer that can sequester hydrogen at a power-storage density a couple times higher than lithium polymer batteries. It's still in laboratory testing and hasn't been commercialized but it looks very promising and could potentially allow car-sized and larger fuel cells to operate without a giant terrifying high pressure hydrogen tank.

    I believe speculation about this breakthrough is mostly driving fuel cell stocks to come back from the dead.

    This would be pretty big as a stepping stone, and possibly the only way to make air travel long term sustainable.

    i mean you'd think that but hydrogen and air travel don't have a positive history

    My prediction is air travel remains on hydrocarbons, just using biofuels instead of oil as the source so it's neutral.

    How efficiently can we generate hydrogen?

    Like if we put a kWh of electricity into our generator, then put that hydrogen into a cell, and the cell spits out 0.25 kWh before it runs dry then... not great.

    (especially since from what I can tell li-ion batteries are about as efficient as you can possibly expect)

    Isn't more that it has the advantages of a "burned fuel" in that the system becomes lighter as you use more fuel, unlike batteries.

    Lithium polymer batteries are extremely poor in terms of energy density in the grand scheme of things. Compared to battery tech of the past they are good and cheap and reusable, but compared to gasoline or a snickers bar, we can see that they are tremendously far from the energy storage upper bound.

    For future fuel cell tech, you make hydrogen gas by splitting water when you are "charging" the cell, then you store the hydrogen in a polymer. When it comes time to run it in reverse, you heat the polymer and the hydrogen is released, and water+power are made. It's a semi-closed system to which you occasionally just add some more water.

    Yeah the density on batteries is bad, but the efficiency is good. So the fuel is exactly as cheap as we can make electricity.

    What I'm saying is, if hydrogen cells are 4x as dense, but the power costs 4x as much, is it worth it?

    Though are you saying the new cell tech does the electrolysis inside the cell? That's neat.
    The last round of hydrogen tech I looked at you'd need to inject gaseous hydrogen into the cell. (Though this did have the advantage of quick charging, disadvantage of needed hydrogen fill-up stations)

    The Gunslinger would be a fantastic low budget, Cannes-friendly movie. I would go sparse as all hell, focus heavily on the massiveness and emptiness of it all... don't blow a wad on a special FX budget but hint at it when they hold palaver and roland drifts off by the fire as flagg talks.

    End on the beach, fade as the sound of the waves crash in the distance... provide zero resolution to anything whatsoever.
    The Boy is dead, merlin seems dead, roland seems kind of irredeemable, the world is massively large and complex and your quest is pointless. The end.

    I would watch that move 1000 times.

    The problem is that I'm not aware of anything (rechargeable) that has anything even close to the energy/weight ratio of a Li+/Li0 system. I guess hydrogen is the only thing that can compete.

    But for both of those the necessary support/containment structures are the vast majority of the weight of the end product, so if you could engineer something that didn't require all that infrastructure it might be possible to beat them.

    Oh I see what you mean. You're talking coulombic efficiency. Charge in vs charge out. Yeah, LiPo batteries are near 100% if you trickle charge and something like 70%-80% with quick charge techniques.

    When running electrolysis of water, the semi-closed battery model, assuming polymer sequester and not pressurization, this process is about 80% efficient. So overall you've got 80% efficient charging on the reverse reaction and then usually for forward step is somewhere like 60% efficient + a bunch of heat produced. More efficient cells have been made by also vamping heat off the cell as it works but I'll keep it modern-day realistic and say that fuel cell systems acting like batteries have a coulombic efficiency of ~50%.

    This efficiency loss is a lot easier to swallow when solar panels and wind turbines are taking the hit. Less so when it's fossil fuel power generation. But regardless, the higher storage density means you can branch out into areas previously off limits. Like air travel or long haul trucking.
