Power-to-Protein: Carbon Fixation with Renewable Electric Power to Feed the World

We are currently amidst a multifaceted crisis regarding food production. The detrimental consequences of animal-based protein production on the environment are becoming increasingly clear.1 The utilization of finite resources, such as land, fossil fuels, phosphorous, and water, accompanied by greenhouse gas emissions, are primary outcomes of conventional livestock production.2 An extensive generation of ammonia via the Haber-Bosch process sustains the plant growth that is required to feed the many animals, but it is inefficient and creates runoff from agricultural lands, resulting in eutrophication on a local and continental scale
