Sources: 2. Developments: 2. Researchers in Germany are advancing biotechnological methods to produce essential nutrients using renewable energy and chemical feedstocks. Initially, the Technical University of Munich developed a solar-powered process that utilizes carbon dioxide, hydrogen, and renewable electricity to create amino acids. This method uses solar energy to produce hydrogen, which is then combined with CO₂ to create methanol, eventually using specialized enzymes to produce a range of seven different amino acids for potential use in animal feed. Building on similar concepts, researchers at the University of Tübingen have demonstrated the economic viability of industrial-scale ‘power-to-protein’ or ‘power-to-vitamin’ production. Their optimized two-step microbial process converts carbon dioxide, hydrogen, and oxygen into proteins and vitamin B9 (folic acid). The study suggests that a facility providing daily recommended doses to 5.6 million people could reach profitability within five years, offering a potential solution to global food security and undernourishment challenges. ## Timeline ### 2026-08-16: University of Tübingen researchers validate industrial biotech protein production University of Tübingen researchers have found that scaling up microbial production of proteins and vitamin B9 using CO2 and hydrogen is economically viable and could help address global food security. 2 sources. https://clstr.news/cluster/university-of-tbingen-researchers-validate-industrial-biotech-protein-production ### 2026-07-27: Technical University of Munich develops solar-powered method to produce amino acids TUM researchers have devised a solar‑electric process that turns CO₂ and hydrogen into amino acids, offering a land‑saving protein source for future food demand. 2 sources. https://clstr.news/cluster/technical-university-of-munich-develops-solar-powered-method-to-produce-amino-acids --- Cite as: German research into biotechnological protein production.
