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.
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.
“Winning”
I believe you mean lobbying.
To a company, those are the same. For us? It’s a pure loss.
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)
That’s quite the game of telephone you’ve established.
I am not claiming there is no real science behind it but it’s still fuel generation and energy storage is possible without needing to create a fuel.
The inefficiency at each step accumulation. The laws of thermodynamics are not negotiable. Fewest conversions is always going to win.
There are plenty of other more useable products we could create from excessive energy, clean water from desalination is a common one.
The theory of excess energy is nonsense. Especially when it comes to solar, which you would optimize to use peak capacity at peak production times. Pumped hydro is vastly more efficient than electrolysis to produce hydrogen, and it doesn’t require us mining. Any precious metals.
Since the point of this research is to reduce the impact of mining, you would think that mining for the catalyst material would have been considered. Those metals are not readily found and bodies of water, for example.
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?
I didn’t read anything beyond the summary
From the linked article
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
Chatgpt says:
Proton batteries are an emerging energy storage technology that uses hydrogen ions (protons) to store and release energy. They split hydrogen gas into protons and electrons at the anode, with a membrane allowing only protons to pass to the cathode. At the cathode, protons combine with oxygen and electrons to generate electrical energy. Proton batteries offer high energy density and potential environmental benefits but are still in early development and face efficiency and cost challenges compared to traditional batteries
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.
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
“ChatGPT, please provide your rebuttal 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
right, and they’re actually pretty bad at remembering facts, that’s why we have entire institutions dedicated to maintain accurate reference material!
why do people throw all of this out the window for advice from a dumb program I’ll never understand
Not really. We also have deductive capabilities (aka “system 2”) that enable us to ensure some level of proof over our statements.
What is the energy density (by volume) 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 cell/electrolysis combo having poor energy efficiency.
Edit: specified density by volume, as density by weight was never the issue
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?
And more pertinent, how small does it get? Fit one in my phone? Motorcycle? Car? Boat?
You asked for the energy density, that’s why it’s relevant?
For the rest of your questions, try Google?
