  • 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.

    2017-12-27 · The solvent-swap operation is based on the selective in-line evaporation of t-BME in three substeps as shown in Scheme 2: (a) in-flight evaporation, (b) droplet crash, and (c) liquid–gas evaporation on the surface liquid on the receptacle placed below. The main aim of this process is to enhance the evaporation surface as much as possible in order to intensify the mass transfer, and subsequently the evaporation.

    The boil-off rate of H 2 is typically 0.4%/day for 50 m 3 tanks, 0.2% for 100 m 3 tanks and 0.06% for 20 000 m 3 tanks (using double-walled vacuum-insulated spherical Dewars). Loss of hydrogen due to boil-off is a problem, although recent work indicates that for the most recent tank designs, venting occurs only in the case of infrequent driving.
