Last month a group of researchers from the Technion Israel Institute of Technology published a paper, “ Decoupled hydrogen and oxygen evolution by a two-step electrochemical–chemical cycle for efficient overall water splitting,” in the journal Nature Energy.  The key word in the title is “efficient.”  In a September 15 Technion press release, the researchers state that their technology “facilitates an unprecedented energetic efficiency of 98.7% in the production of hydrogen from water.”  Applied to the appropriate use case, the technology could lead to a major improvement in green ammonia’s ability to compete with brown ammonia and other low-carbon energy carriers.
