Anyone know what the catch is here? Very exciting if real, but sometimes these things don't scale/aren't commercial/something else I'm ill-equipped to perceive. Not trying to knock this by any means, I hope it works wonderfully!

Scaling up could be limited by the availability of Boron:

> Boron is synthesized entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, so it is a low-abundance element in the Solar System and in the Earth's crust.[12] It constitutes about 0.001 percent by weight of Earth's crust.[13]

> Global proven boron mineral mining reserves exceed one billion metric tonnes, against a yearly production of about four million tonnes

The catch is that hydrogen storage is the smallest of the problems facing the nascent hydrogen economy. Energy losses in electrolysis and in the conversion from hydrogen to electricity are by far the biggest piece of the efficiency-loss pie.

Once the boron nitride powder is heated to release the captured hydrogen, can it be reused to capture again?

It uses boron nitride which seems relatively easily available in large-ish quantities: https://www.alibaba.com/product-detail/nano-boron-nitride-po...

The catch is that the parent article is extremely confusing.

The real research article

https://www.sciencedirect.com/science/article/abs/pii/S13697...

has nothing about the storage of pure hydrogen (a.k.a. dihydrogen), which would be very surprising if achieved, but about a better method for the separation and storage of certain unsaturated hydrocarbon gases, e.g. acetylene or ethylene (which can be absorbed by boron nitride powder and released later).
