Dont forget that one...its still of interest to geologists, I understand there might even be new papers on it, due to the obvious energy benefits if hydrogen pockets arae found...

And what if there two or more of the mechanisms here are not enough on their own, but if they interacted to produce the required mass ?

So even if one mechanism cannot produce the mass, a good idea to eliminate those that are not plausible at all, and look for integrations of mechanisms.

According to the wiki link:
"Starting with the first principles, Larin proposed an explanation for the observed distribution of elements throughout the Solar system."
and "Assuming that the primordial abundance of the elements was similar to the current composition of the sun, the scheme accounts for the present rocky and metallic inner planets and gaseous outer planets."

This theory was originally built to explain the distribution of planets in the solar system. But recent data show that systems are much more diverse. For example, gaseous planets are orbiting very close to the central star. So the original assumption is wrong.

Now, even if the premise of the theory is wrong, it does not mean that the Earth's mantle (and/or core) must not contain large amount of Hydrogen. Francesco Stoppa (Geochemist/Volcanologist) gave a talk last year at Erice supporting this hypothesis.
