Research

What are the fuels of the future? It is intriguing to consider that a nitrogen economy, where hydrogen obtained from water splitting is chemically stored on abundant nitrogen in the form of a nontoxic and safe nitrogen‐based alternative fuel, is energetically feasible.

Splitting water splitting: we decouple the hydrogen and oxygen evolution reactions by dividing the process into two steps: an electrochemical step that reduces water at the cathode and oxidizes the anode, followed by a spontaneous chemical step that is driven faster at higher temperature, which reduces the anode back to its initial state by oxidizing water.

The E-TAC water splitting DEMO system at H2PRO. H2PRO was founded in 2019 by leading hydrogen experts from the Technion (Israel Institute of Technology): Dr. Hen Dotan and Profs. Gideon Grader and Avner Rothschild in collaboration with the team that founded Viber, Juno and iMesh.

The intermediate-temperature wash fluid in the grey tank on the left is circulated through a bypass most of the time. This fluid is used to ‘push’ the cold and hot electrolyte solutions to their respective tanks at the end of the H2 generation or O2 generation steps.
