The future of sustainable energy lies in breaking the boundaries between biology and electrochemistry and building an efficient and clean energy conversion and storage system. In the field of biomanufacturing, the use of microorganisms to convert renewable energy sources (e. g. green hydrogen, electrons) into liquid fuels or chemicals is a promising direction. Researchers have modified microorganisms such as acetic acid-producing bacteria through metabolic engineering, enabling them to use electricity or hydrogen to reduce carbon dioxide, synthesize energy carriers such as acetic acid and butanol, and realize the energy storage form of "electricity-liquid". In terms of electrochemical energy storage, solid-state battery technology is gradually solving the problem of interface impedance. By developing solid-state electrolytes with high ionic conductivity, scientists are working to replace flammable liquid electrolytes, which greatly increase the energy density and safety of batteries, which are crucial for electric vehicles and grid-level energy storage. In addition, green hydrogen preparation technology is also constantly iterating, and the catalyst for hydrogen production from proton exchange membrane electrolysis water is being de-preciousized, which greatly reduces the cost of hydrogen production by developing high-activity transition metal phosphide or sulfide catalysts. These technological breakthroughs are building a zero-carbon energy Internet with electricity as the core and hydrogen and biomass as the wings.
