Adsorption Storage of Gaseous Hydrogen at Cryogenic Temperatures
The storage of hydrogen on board vehicles is one of the most critical issues for the transition towards an hydrogen-based transportation system. The physical adsorption of hydrogen on activated carbon can reduce the pressure required to store compressed gases. Though an efficient adsorption-based storage system for vehicular use of natural gas can be achieved at room temperature, the application of this technology to hydrogen using activated carbon as the adsorbent requires its operation at cryogenic temperature. In this paper we present a comparative study of the efficiency of adsorption and compressed gas storage of hydrogen as a function of temperature and pressure. The isothermal hydrogen storage and net storage densities for passive systems at 77 K, 150 K and 293 K are compared and discussed.
