abstract = {The decision of the European Union to make Europe the first
carbon dioxide-neutral continent on earth pushes
environmental-friendly technologies in all technical areas
drastically forward. Thus, for the energy sector the
conversion of kinetic energy into electricity must be
ensured by non CO2-emitting techniques like wind and solar
power (so called regenerative sources). As both are
depending on natural limitations (wind blowing, sun shining)
electricity storage becomes the dominant pre-requisite for
such a regenerative-based energy future. Therefore,
electrolyzers (low- and high-temperature) will be
established in the future to a large extent. As SOECs are
typically based on classical SOFC technology they are easily
available and capable of being integrated. One additional
aspect to the carbon-neutral future is that all technologies
must also be striven forward with respect to refurbishing,
reuse or recycling (Fig. 1). Within the “Energiewende”
the German government has proclaimed the goal of “green
hydrogen” as basis of its use as direct fuel or first link
to an e-fuel or chemical development chain. In this context,
a BMBF-funded technology platform H2Giga was founded with
the aim of establishing the existing electrolyzer
technologies on an industrial scale. Part of the technology
platform is a recycling-related project called ReNaRe aiming
for recycling possibilities and strategies for
electrolyzers. The own research will focus on the first
steps within the project dealing with recycling and reuse of
either the metallic parts or the ceramic parts of an SOEC
stack. The required stack or stack parts are delivered by
Hexis and Jülich and hopefully also from Sunfire (being
part of H2Giga) and characterized with respect to recycling
possibilities, ways and technologies. First recycling ideas
related to different SOC designs will be presented.},
