hydrogenase. biocatalyst for 90% effective and green H2

Israeli Energy Minister Karine Elharrar said, “As David Ben-Gurion put it, security is energy. We need a combination of different types of energy, and the crisis in Europe shows that we can’t give up on any of them at the moment. We must lead the world of energy https://english.tau.ac.il/Green_Hydrogen_2023 Over 90% Efficiency The new method was developed by doctoral student Itzhak Grinberg and Dr. Oren Ben-Zvi, under the guidance of Prof. Iftach Yacoby of the School of Plant Sciences and Food Security at the Wise Faculty of Life Sciences and Prof. Lihi Adler-Abramovich of the Goldschleger School of Dental Medicine and the Center for Nanoscience and Nanotechnology. The promising research results were published in the prominent journal Carbon Energy, focusing on advanced materials and technology for clean energy and CO2 emission reduction. “Hydrogen is very rare in the atmosphere,” explains Itzhak Grinberg, “although it is produced by enzymes in microscopic organisms, which receive the energy for this from photosynthesis processes. In the lab, we 'electrify' those enzymes, that is, an electrode provides the energy instead of the sun. The result is a particularly efficient process, with no demand for extreme conditions, that can utilize electricity from renewable sources such as solar panels or wind turbine. However, the enzyme ‘runs away’ from the electric charge, so it needs to be held in place through chemical treatment. We found a simple and efficient way to attach the enzyme to the electrode and utilize it.”
