To say it simple:a hydrogen bond is a special case of (rather strong) dipole-dipole attraction between two atoms.

So no, there is no way to have a hydrogen bond without the H atom connected to another atom.

 According to this page hydrogen iodide, HI, with a bond energy of 71
kcal/mole can be decomposed into H and I by uv light at a wavelength of
266 nm:

 Are there other gases where a single hydrogen atom can be dissociated
at a lower energy?
