There are high hopes for hydrogen as the key to the energy transition. A specific enzyme group found in algae and in bacteria can produce molecular hydrogen simply by catalyzing protons and electrons. However, the enzyme group is so sensitive to oxygen that commercial use of the hydrogen produced by this process as a green energy source is not yet possible. Researchers have now increased the oxygen stability of a hydrogen-producing enzyme by genetically generated channel blockages.
