The global food demand is projected to significantly increase. To maintain global food security in the future,
protein production needs to become more efficient regarding the use of limited land and water resources.
Protein-rich biomass can be produced via direct air capture of CO2 with the help of H2-oxidizing bacteria and
renewable electricity in a closed, climate-independent system. This quantitative literature review conservatively
estimated the direct land and water use of bacterial protein production relying on secondary data for the
components of the technology and for the reference protein sources. A several times higher potential protein
yield per land area can be achieved by this technology with approximately one-tenth of the water use compared to that required for soybean production.
