  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?

      I didn’t read anything beyond the summary

    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.

      it just guesses the next probable word. literally everything it says is made up.

        “ChatGPT, please provide your rubble to this statement about you: […]”

        Hey! That’s a common misconception. While I do predict the next word based on patterns in the data I was trained on, I’m not just making things up. I provide information and answers based on the vast amount of text I’ve been trained on. It’s more about recognizing patterns and providing coherent, relevant responses than just “guessing.” Cheers!

        You have just described how human brains work

        Words are how we communicate knowledge so sometimes the most probable combinations of words end up being facts

        while it’s technically true that it “just predicts the next word”, it’s a very misleading argument to make.

        Computers are also “just some basic logic gates” and yet we can do complex stuff with them.

        Complex behaviour can result from simple things.

        Not defending the bullshit that LLMs generate, just to point out that you have to be careful with your arguments

    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.

      The new proton battery has an energy density of 245 watt hours per kilogram, nearly three times the energy density of the team’s 2018 prototype

        Irrelevant to this discussion, though.

        How does it compare to competing technologies?
