@ooli tl/Dr "Photoncycle
Brandtzaeg holds up a chalk-looking substance: “With this, you can store electricity 20 times as densely as in a lithium battery.”

“We're locking up the hydrogen molecules in a solid to basically fix them. We're using a reversible, high-temperature fuel cell, so we're assisting a fuel cell which both can produce hydrogen and electricity in the same cell,” he says.

That means no need to cool the hydrogen down, making it non-flammable and giving it a higher density than an ion-lithium battery"

I wonder what's the volumetric energy density, historically that has been a bigger issue than gravimetric energy density.

@JohnDClay

Good question, this article is pretty fluffy, not a lot of hard data. Reads kind of like a fluffed up press release honestly.

This was totally a fluff investment article for funding.
