Electro-agriculture: Revolutionizing farming for a sustainable future

Abstract

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.
