I studied Raney Ni and found no evidence for extra heat. The material
is actually an Ni-Al alloy that contains a small fraction of Al. It is
very reactive to oxygen, unreactive to water and unreactive to H2. It
is dangerous to use without care.

Hi Jack,
I had the same idea a couple of years ago. It gets even more
interesting when you realize that the NiAl + NaOH reaction produces
Raney Nickel (google it - it is a nano-porous material) which has
very interesting properties. The reaction effectively pre-loads the
Raney Nickel 'metallic foam' with Hydrogen.
I wonder if anyone has looked for anomalous heat in this process. I
suspect not.

Since either potassium hydroxide or sodium hydroxide react with
aluminum to produce hydrogen, I wonder if NiAl wire in electrolysis
with KOH or NaOH might prove interesting. Any thoughts?
Perhaps even simpler would be adding this wire to a solution of KOH
or NaOH without electrolysis. I don't know if the hydrogen
produced would load into the lattice.
Best regards,
Jack
