Technology Description:

The University of Minnesota will design a cell-free biocatalytic system that will reduce CO2 efficiently into formate, an important feedstock for chemicals and fuels, with energy supplied from electricity. Renewable electricity is now competitive with and in many instances less expensive than fossil fuel-derived electricity, but its storage remains challenging. Energy storage in chemical bonds through electricity-driven carbon reduction offers higher energy densities and greater safety and transportability than batteries. The efficient electrochemical reduction of kinetically and thermodynamically stable CO2 into a range of chemicals requires significant innovation. If successful, the University of Minnesota will deliver two major products for commercialization: (1) a portable CO2 capture technology and (2) formate as stand-alone chemical or for conversion in value-added compounds.

Potential Impact:

The application of biology to sustainable uses of waste carbon resources for the generation of energy, intermediates, and final products---i.e., supplanting the “bioeconomy”—provides economic, environmental, social, and national security benefits and offers a promising means of carbon management.


If successful, the new technologies are expected to catalyze new conversion platforms for biofuels and other high-volume bioproducts that are capable of promoting U.S. energy security by increasing recoverable product from the same mass of feedstock through the avoidance of wasting carbon in the form of CO2.


This program funds cutting-edge technologies to de-risk the engineering of carbon optimized bioconversion pathways capable of generating valuable bioproducts such as sustainable aviation fuel without emission of CO2 as a waste product.


The technologies funded by this program can increase the potential bioproduct output by more than 40% without requiring another square inch of land or pound of feedstock, while catalyzing the next generation of carbon optimized bio-based manufacturing.
