New study exploring CO2 conversion in single-chamber electrochemical systems

Researchers from Universitat Autònoma de Barcelona have published a new study exploring how single-chamber electrochemical systems can efficiently convert CO₂ into formate under biocompatible conditions, a valuable step forward in integrating electrochemical and biological processes for sustainable production.

This work is part of the PhD research of Zainab Ul Kausar, supervised by Mira Sulonen, Albert Guisasola Canudas, and Juan Antonio Baeza, and was developed in collaboration with Paniz Izadi, Philip Haus, and Falk Harnisch from Helmholtz Centre for Environmental Research, also a VIVALDI partner.

While double-chamber systems have been the standard, this study demonstrates that single-chamber setups (simpler and potentially more cost-effective) can still achieve strong formate production levels suitable for microbial fermentation.

This research reinforces VIVALDI’s mission: turning CO₂ into valuable products through collaborative, cross-disciplinary innovation.
