A hybrid inorganic-biological artificial photosynthesis system for energy-efficient food production

Elizabeth C. Hann et al.

Summary: Artificial photosynthesis systems can capture CO2 and produce a highly concentrated acetate stream, which can be used for heterotrophic cultivation of yeast, mushroom-producing fungus, and photosynthetic green algae. Coupling this approach with photovoltaic systems can significantly improve solar-to-food energy conversion efficiency and reduce the required solar footprint. This technology allows for a reimagining of food production in controlled environments.
