“…Combined with light-vehicle electrification, biofuels could thus play a major role in decarbonization of the transportation sector . Of note, the methods of biomass production rely heavily on sustainable, “second-generation” energy crops that remove the competition for arable land with food sources . Beyond just dedicated crops, it is estimated that the global generation of biomass waste, including residues from industries of biomass-based materials production (e.g., logging, pulp and paper industry), as well as production, processing, retail, and consumption of human food and animal feed, is 100–140 gigatons/year (Gt/y). , Assuming an inherent carbon content of approximately 50 wt%, 140 Gt/y of biomass (i.e., 70 Gt/y carbon) has the potential to satisfy the entire global demand for gasoline, diesel, and jet fuel by factors of 45, 63, and 185 times over, respectively. , Demands for ethylene and propylenethe top two carbonaceous industrial chemicals by volume, at ∼150 and ∼120 Mt/y, respectivelycould be met by almost 300 times over .…”

The drive to reduce consumption of fossil resources, coupled with expanding capacity for renewable electricity, invites the exploration of new routes to utilize this energy for the sustainable production of fuels, chemicals, and materials. Biomass represents a possible source of platform precursors for such commodities due to its inherent ability to fix CO 2 in the form of multi-carbon organic molecules. Electrochemical methods for the valorization of biomass are thus intriguing, but there is a need to objectively evaluate this field and define the opportunity space by identifying pathways suited to electrochemistry. In this contribution we offer a comprehensive, critical review of recent advances in lowtemperature (liquid phase), electrochemical reduction and oxidation of biomass-derived intermediates (polyols, furans, carboxylic acids, amino acids, and lignin), with emphasis on identifying the state-of-the-art for each documented reaction. Progress in computational modeling is also reviewed. We further suggest a number of possible reactions that have not yet been explored but which are expected to proceed based on established routes to transform specific functional groups. We conclude with a critical discussion of technological challenges for scale-up, fundamental research needs, process intensification opportunities (e.g., by pairing compatible oxidations and reductions), and new benchmarking standards that will be necessary to accelerate progress toward application in this still-nascent field.
