CO₂ Sources and Infrastructure

Work in phase 1

Subproject L1 “Water Electrolysis” investigated the possibilities of providing the necessary climate-neutral hydrogen. The focus here lay on producing hydrogen by means of water electrolysis using volatile renewable energies. A larger plant in the technical center and smaller test stations with different electrolysis processes were operated for this purpose. In particular, it was possible to investigate more closely the aspect of degradation during dynamic operation in the laboratory and in the technical center.

Aims in phase 2

In the second project phase, the focus in subproject L-I “CO₂ Sources and Infrastructure” lies on other CO₂-intensive industries such as the cement and lime industry, as well as thermal waste treatment. Solutions that have already been developed should be transferred to these industrial sectors and thus provide evidence that the Carbon2Chem^® technology modules are able to minimize cross-industrial CO₂ emissions, also making them transferrable to smaller locations. This transformation is a long process and requires sufficient availability of renewable energy and hydrogen. As part of L-I, this transformation path and the effects on the availability of CO₂/CO over time should be investigated. This also includes consideration of the necessary infrastructure for hydrogen and CO₂.
