Tandem Electrolysers for High‐Efficiency CO2‐to‐Acetate Conversion Driven by Full‐Spectrum Solar Energy

Carbon Energy, EarlyView.
A full‐spectrum solar‐driven tandem electrolysis system enables efficient CO2‐to‐acetate conversion by spectrally splitting sunlight and coupling high‐temperature SOEC CO2‐to‐CO electrolysis with ambient CO reduction. The integrated design achieves a solar‐to‐acetate efficiency of 15.8%, demonstrating effective energy‐quality matching for solar carbon ...
