Z-neutrino energy was a type of energy used by the New Dalek Empire.

The power source at the core of the Dalek flagship called the Crucible consisted of Z-neutrino energy. The energy was powerful enough that it could tear apart a TARDIS with its defences down. It was used along with the planetary alignment field of the 27 planets which were taken by the Empire to create Davros' Reality bomb. The energy was focused by the planetary alignment field into a single stream, intended to neutralise the electrical charge of every single atom in the universe outside the planetary alignment field.
