Summary Zirconium alloys are currently used in nuclear power plants where they are susceptible to hydrogen pick‐up. Hydride precipitation may occur when the hydrogen solubility limit is reached. Various Zr hydride phases, γ, δ and ɛ have been identified since the 1950s. Combining electron precession microdiffraction, electron energy loss spectroscopy and ab initio electronic calculations, a new Zr hydride named ζ has been identified and characterized. It belongs to the trigonal crystal system with space group P3 m1 and it is fully coherent with the αZr matrix.
