  • Large-scale storage of hydrogen - ScienceDirect

    2019-5-3 · As mentioned earlier, the most commonly suggested refrigerant is liquid nitrogen, which has a heat of evaporation of approximately 0.056 kWh/kg nitrogen. If one considers an adsorbent which has a hydrogen adsorption enthalpy of 4 kJ/mol, or 0.56 kWh/kg, this means that at least 10 kg of liquid nitrogen need to be evaporated to remove the heat of adsorption of 1 kg of hydrogen.
