Abstract

This poster summarizes at a high-level the scope of various groups' work on Formate as an Energy Source to Allow Sugar Fermentation with No Net CO2 Generation: Integration of Electrochemistry with Fermentation. The goals of this research are to develop and demonstrate an integrated process that electrochemically generates formate from CO2 and use the formate as an energy source for the fermentation of sugars to fatty acid methyl esters (FAME) without net CO2 generation wherein formate provides reducing equivalents for sugar fermentation and a chemical looping reactor system takes advantage of intermittent low-cost electricity from wind and solar resources.
