Greener Alternative To Lithium-ion Battery

  This isn’t really an “emerging” battery tech, and there have been all kinds of hyped “breakthroughs” about hydrogen batteries for a long time. The issue here, like always, is that it does not scale, the cost is absurd, the tech is improving slower than Lithium batteries, and this essentially takes the working parts of a fuel cell but makes the storage foolishly low.

  There are also no end-of-life environmental challenges with a proton battery, since all components and materials can be rejuvenated, reused or recycled.”

  The same is true of Lithium cells, but the problem historically has been that recycling is more expensive because the volume of cells being recycled is vanishingly small. The ability to recycle a product doesn’t determine whether or not it is recycled, which is a really unfortunate truth we have to face.

    Yep, RecycLiCo in Canada proving they can extract the minerals from the recycled batteries black mass to get as good as or better than original

    The oil industry is behind the the push for hydrogen.

    They desperately need to replace fuel for fuel or they’ll cease to exist.

      I spoke to a partner of a friend whose working on hydrogen cells and “low temp” (600c, though earlier versions were 800-1000c) cerium or Cesium yttrium catalyst electrolysers. The point of the electrolysis pathway is that you’re able to use excess energy from green sources (solar/hydro/nuclear) that we currently don’t have the infrastructure to store, to produce hydrogen for use in hydrogen cells or to be used as an alternative to fossil fuel derived hydrogen in metallurgical processes (steel making etc)

      Without a doubt. But they’re also behind nat gas powered plants, solar and wind farms, charger networks, etc. The thing about the oil companies is they became multinational juggernauts by always winning. And they’ve lined themselves up to win on “green” energy as well as renewables, solar, wind, and tidal.

  So what is this made of if not lithium?

    The battery uses a carbon electrode to store hydrogen that has been split from water, and then works as a hydrogen fuel cell to produce electricity

    Carbon. Much cheaper, and basically, infinitely abundant. Big big big deal if they can scale it.

      That always seems to be the rub. You can make these breakthroughs in a lab, but if they can't be translated to manufacturing, then it's not a huge achievement.

      What’s the round trip energy efficiency?

      Don’t use chatgpt as a source, there is no reason to trust anything it says.

      It might be right, it might have just thrown together words that sound right, or maybe it’s completely made up.

      What is the energy density of this? It sounds like a rebrand of a hydrogen fuel cell, which has some limited applications, but has been supplanted by lithium-ion due to hydrogen’s low energy density and the fuel cells/electrolysis combo having poor energy efficiency.
