Researchers at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences and their collaborators have begun a large-scale project demonstrating photovoltaic powered production of hydrogen, which is then used to convert carbon dioxide into methanol.
The French startup Qairos Energies says it plans to build a plant in Mareil-en-Champagne near Le Mans in northwestern France that will gasify hemp biomass into valuable products.
Oxygen inhibits hydrogenases, a group of enzymes that are able to produce and split hydrogen. This degradation is fatal for possible biotechnological applications of these enzymes for the production of clean energy. Understanding the mechanisms of this process is hence essential. Researchers from UCL (UK) and CNRS (France), including an Ikerbasque Research Fellow from CIC nanoGUNE, have characterized each chemical reaction step that results in the reduction of oxygen by the enzyme.
The researchers developed “P22-Hyd” by modifying an enzyme and placing it within a protective protein shell, a “capsid”, from a bacterial virus. The strengthened biological catalyst is 150 times more efficient than the original enzyme.
