If you browse google for nickel nanopowder and hydrogen, then you find
countless scientific research articles.
Of course almost all must be payed.
It is mentioned that water resulting from the process can poison the
process and this is still heavily researched.
There is not one process, there are hundrets of research and proprietery
industrial processes that involve nickel powder and hydrogen.
Yes Nickel powder and Raney nickel can self ignite on air and is
dangerous and toxic but there are no dangers in combination with
hydrogen mentioned. The biggest danger is, it doesnt work, and they try
all tricks to make it work.
Especially never neutrons or soft gamma-rays or gamma-ray injury of
persons where reported.

One would not have to use pure Hydrogen; I bet they have identified an
H2-Noble Gas mixture that is slow-enough to be safe. You can dissolve
most metals in acid and cause them to precipitate as nano-particles.
The you would expose it to your gas mixture.
