Green hydrogen: Research to enhance efficiency
(PHYSorg.com Chemistry)

Laboratory experiments and a parabolic flight campaign have enabled an international team of researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) to gain new insights into water electrolysis, in which hydrogen is obtained from water by applying electric energy. Water electrolysis could play a key role in the energy transition if efficiency improvements can be achieved. The findings published recently in the journal Physical Review Letters offer a possible starting point for enhancing the environmental impact of hydrogen-based technologies.
