It looks interesting, but the article has too few details. Some more info in the first reference https://pmc.ncbi.nlm.nih.gov/articles/PMC11936013/ Anyway, IIUC it discuss a research lab method, that may be hard to escale to factory production.

It being used in some medicines, and in semiconductor processes, then in preserving Blue OLED for longer.

from the article:

Stable, NON radioactive isotope of hydrogen with one proton and one neutron in its nucleus. Natural abundance of 0.015% of hydrogen atoms on Earth
