This dataset presents the nitrogen adsorption isotherms for a range of powders and monoliths formed from them used to calculate their BET surface area. Hydrogen isotherms are also produced to show the storage capacity for the same entities. A comparison of the mass of hydrogen stored using the monoliths compared with compression is also included. A comparison of the mass of hydrogen stored by compression at different conditions with activated carbon AX21 at different conditions is included. The effect of the volume of adsorbent on the mass of hydrogen stored is also included.
