title: Reply to 'Comments on "Evidence of the hydrogen release mechanism in bulk MgH2"'.
abstract: In a comment on our Article "Evidence of the hydrogen release mechanism in bulk MgH2", Surrey et al. assert that the MgH2sample we studied was not MgH2at any time but rather MgO; and that the transformation we observed was the formation of Kirkendall voids due to the outward diffusion of Mg. We address these issues in this reply.
