For millennia, humanity has depended on photosynthesis to cultivate crops and feed a growing population. However, the escalating challenges of climate change and global hunger now compel us to surpass the efficiency limitations of photosynthesis. Here, we propose the adoption of an electro-agriculture (electro-ag) framework that combines CO2 electrolysis with biological systems to enhance food production efficiency. Adopting a food system based entirely on electro-ag could reduce United States agricultural land use by 88%, freeing nearly half of the country’s land for ecosystem restoration and natural carbon sequestration. Electro-ag bypasses traditional photosynthesis, enabling food cultivation in non-arable urban centers, arid deserts, and even outer space environments. We offer a new strategy that improves energy efficiency by an order of magnitude compared with photosynthesis, along with essential guidance for developing electro-ag focused on staple crops, to maximize benefits for regions facing food insecurity. This innovative approach to agriculture holds significant promise in reducing environmental impacts, streamlining supply chains, and addressing the global food crisis. 

In this study, we elucidate the reaction kinetics for the simultaneous hydrodeoxygenation of xylitol to 1,2-dideoxypentitol and 1,2,5-pentanetriol over a ReOx-Pd/CeO2 (2.0 weight% Re, 0.30 weight% Pd) catalyst. The reaction was determined to be a zero-order reaction with respect to xylitol. The activation energy was elucidated through an Arrhenius relationship as well as non-Arrhenius kinetics. The Arrhenius relationship was investigated at 150–170 °C and a constant H2 pressure of 10 bar resulting in an activation energy of 48.7 ± 10.5 kJ/mol. The investigation of non-Arrhenius kinetics was conducted at 120–170 °C and a sub-Arrhenius relation was elucidated with activation energy being dependent on temperature, and ranging from 10.2–51.8 kJ/mol in the temperature range investigated. Internal and external mass transfer were investigated through evaluating the Weisz–Prater criterion and the effect of varying stirring rate on the reaction rate, respectively. There were no internal or external mass transfer limitations present in the reaction.
