Capturing CO2 with electricity: A microbial enzyme inspires electrochemistry      (via sciencedaily.com)     Original source 

Humanity continuously emits greenhouse gases and thereby worsens global warming. Increasing research efforts go into developing strategies to convert these gases, such as carbon dioxide (CO2), into valuable products. CO2 accumulates dramatically over the years and is chemically very stable, thus challenging to transform. Yet, for billions of years, some microbes have actively captured CO2 using highly efficient enzymes. Scientists have now isolated one of these enzymes. When the enzyme was electronically branched on an electrode, they observed the conversion of CO2 to formate with perfect efficiency. This phenomenon will inspire new CO2-fixation systems because of its remarkable directionality and rates.
