Researchers from the Indian Institute of Technology (IIT) Madras have developed a technology that can be used to generate hydrogen fuel from seawater, an advance that may contribute to a cleaner energy future. Using this technology, described in the journal ACS Sustainable Chemistry & Engineering, hydrogen can be produced on-demand at the point of use, and hence it need not to be stored. This overcomes the storage-related challenges associated with hydrogen as its highly inflammable and may cause an explosion, the researchers said.
