In Israel, The Jerusalem Post reported that a team of researchers from Tel Aviv University (TAU) has produced green hydrogen.
Their research was published in a study in the peer-reviewed Carbon Energy journal, according to the report.
The TAU team produced hydrogen using a water-based gel to attach the enzyme to the electrode and a biocatalyst. Over 90% of the electrons introduced into the system were deposited in the hydrogen without any secondary processes, the report added.
“Hydrogen is very rare in the atmosphere, although it is produced by enzymes in microscopic organisms, which receive the energy from photosynthesis processes,” explained Itzhak Grinberg, a doctoral student who helped lead the project. “In the lab, we ‘electrify’ those enzymes. That is, an electrode provides the energy instead of the sun.”
The team expects this method could be commercially implemented in the future to lower the cost of green hydrogen production.
