Carbon dioxide and other greenhouse gases have been long characterized as one of the leading causes of global warming. And with the seemingly limitless sources of emission — from general breathing of countless living species to vehicular and industrial emissions — the amount of carbon dioxide seems to be ever increasing. It is then, a huge waste of a resource when you consider how comparatively limited the human use of this abundant gas is. The paper “The O2-assisted Al/CO2 electrochemical cell: A system for CO2 capture/conversion and electric power generation”, published in Science Advances, aims to change that. Prof. Lynden Archer, chemical and biomolecular engineering, the James A. Friend Family Distinguished Professor of Engineering, and Wajdi Al Sadat, grad — who are the authors of this paper — have created a cell which can use carbon dioxide to produce electricity via electrochemical reactions.
