Hydrogen recovery from liquid metals

gas-liquid interfacehydrogenNuclear fusion


The process uses a porous membrane to recover hydrogen isotopes from liquid metals and to realize gas sensors for the measurement of the hydrogen isotopes concentrantion into liquid metals. The membranes developed can be used to produce hydrogen from dehydrogenation reactions at high temperature (i.e. water decomposition).

Technical features

The device developed is a Membrane Gas-Liquid Contactor consisting of a porous membrane where a gas-liquid interface allows the hydrogen isotopes extraction from liquid metals. It can be used to to recover hydrogen isotopes from the breeding blankets of the nuclear fusion reactors and for realizing gas sensors in the liquid metals. Another applications concerns the realizazion of liquid metal membranes operating at high temeprature for producing hydrogen via dehydrogenation reactions (for instance the thermal water decomposition).

Possible Applications

  • Tritium extraction from the breeding blankets of the nuclear fusion reactors;
  • Gas sensors for detecting the hydrogen concentration into liquid metals;
  • Membrane reactors operating at high temperature to produce hydrogen via thermal water decomposition.


  • High hydrogen extraction efficiency from liquid metals and high durability;
  • Measurement of hydrogen concentration into liquid metals with quick response and high sensitivity;
  • Thermal water decomposition to produce hydrogen with high reaction yield.
