But then couldn't it be a two part
process, leading to this:

H202 + 2Cu --> 2CuO + H2
CuO + 2HCl --> CuCl2 + H20

thus leading to hydrogen generation. This might be completely wrong
though... Any opinion very much appreciated

No- hydrogen is not evolved in this reaction. Your first reaction
could be H2O2 + Cu --> CuO + H2O, but this would not be an accurate
representation of the mechanism.
