Superconductive undulators have been developed at the German synchrotron light source ANKA for about 15 years. These insertion devices have the potential of overcoming the fundamental limits of permanent magnet undulators in terms of field strength and short period lengths. Thereby the spectral range of the synchrotron radiation accessible may be significantly extended. Moreover, superconductive undulators provide the opportunity of controlling key parameters like the field amplitude and direction purely electrically without mechanical movements. In March 2005 the first cold-bore superconductive undulator designed for storage ring operation was installed and successfully tested at ANKA. A second generation of specialised superconductive undulators capable of electrical polarisation control, electrical period doubling and electrical field error compensation is currently developed. This contribution gives an overview over the status and future prospects of the superconductive undulator development at ANKA.
