HZB-EPFL tandem campaign
The Helmholtz Zentrum Berlin for Materials and Energy (HZB) & the École Polytechnique Fédérale de Lausanne (EPFL) carried out a joint campaign at the High flux solar simulator (HFSS), Lausanne in the first week of June 2023. The experiments served as a demonstration for the integration of the PEC (Photoelectrochemical conversion) reactor of WP1 and the EC (Electrochemical conversion) reactor of WP3 to carry out tandem electrolysis of CO2 to CO and CO to hydrocarbons. The weeklong experimental campaign focused on relating the operational conditions of the individual reactors to the performance of the integrated PEC-EC device across various performance metrics.
