A kind of energy storage technology: Metal organic frameworks

Abstract

Abstract- For last fifteen years energy has been transferred by using electricity. As an energy carrier electricity has some disadvantages like its wire need for transportation and its being non-storable for large amounts. To store more energy safely and to transport it easily, new storing medias and devices are needed. Metal hydrides, carbon nanotubes, metal organic frameworks (MOFs), compressed gas hydrogen and liquid hydrogen systems are being investigated to store and transport hydrogen safely and easily. To use hydrogen as renewable and sustainable energy source on board for transportation and many mobile applications economically and efficiently, USA Department Of Energy (DOE) had set targets for 2010 and 2015. System gravimetric and volumetric density should be 5.5 % wt and 40 g/L respectively according to DOE. To meet the DOE 2015 targets a novel organometallic valin-Cu(II) complex studied. After metal organic framework structured valin-Cu(II) complex synthesis, it is characterized by elemental analysis, X-Ray, FT-IR and thermo analytic TG-DTG techniques. And then hydrogen storage capacity of complex is determined by HPVA-100 adsorption analyser.
