Hydrogen doubles as coolant and working gas in new metal hydride compressor

A joint research team from the Helmut Schmidt University/ University of the Bundeswehr in Hamburg and the Helmholtz Zentrum Hereon has developed and presented an innovative metal hydride compressor system. For the first time, hydrogen takes on a dual function: it serves not only as the medium to be compressed but also simultaneously as a heat transfer agent. The results were recently published in the journal Communications Engineering and have been patented in advance.
