Feasibility case study of reducing green gas emissions by converting CO2 to make Formic Acid

The electrochemical reduction of CO2, ERCO2, is considered one of the most promising strategies to valorize waste-CO2 as a feedstock to produce value-added chemicals, such as formic acid (FA), carbon monoxide, methane, ethene and methanol. Among these ERCO2 products, FA is valuable building block with a mature market and a relatively high value. It is used in food technologies, agriculture, pharmaceutical industry and in the production of leather and textiles. Currently, the synthesis of FA is a fossil fuels-based process, which is not straightforward neither environmentally friendly. According to some estimations, the electrochemical production of FA may become cheaper than commercial routes. It is also an appealing strategy to cope with the stringent environmental regulations on greenhouse gas, GHG emissions.

Recently, an article was published in the peer reviewed journal ChemElectroChem that reports a technical-economic analysis of ERCO2 to Formic acid (FA)/formate using Sn-based cathode in aqueous electrolyte considering the most promising electrochemical routes reported in the literature. Five of the most promising case studies were analyzed in the paper.
