  • Oxygen Tanks or Cylinders - Overview and Use of Oxygen

    The 'E' tank is a 3-foot tall aluminum tank that weighs about 8 pounds and carries anywhere from 2,200–3,000 PSI of compressed oxygen gas depending on the manufacturer. If used continuously at 2 liters per minute, an 'E' tank will last about 5–6 hours. While the 'E' tank is still considered portable, it is too tall to be carried safely over ...

  • 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.
