4 Hydrogen storage Alternative ways of storage include: Metal hydrides Cryogenic adsorption Chemical hydrides Liquefaction (at 20 K and 1 bar) Compression (at 298 K and 350 or 700 bar) Sodium alanate AX-21 Ammonia borane David, WIF.

5 Hydrogen storage Eberle et al. Angewandte Chemie International Edition (2009) 48,
6 Hydrogen storage in porous materials Storage in porous materials can increase its volumetric density at higher temperatures than liquefaction and lower pressures than compression Synthetic chemistry of highly porous materials has known tremendous developments and new materials include metal-organic frameworks and porous polymers Topic: metal-organic frameworks NU-100 (6,100 m 2 g -1 ) Furukawa, Yaghi et al.

8 Hydrogen storage in porous materials Absolute and excess adsorption In a supercritical fluid, this difference is negligible at low pressures but becomes very significant with increasing pressures Experimental sorption techniques (volumetric and gravimetric) can only account for excess adsorption Because adsorptive storage of hydrogen will most likely occur above the critical temperature and at high pressures, understanding and quantifying absolute adsorption is critical
