A Kind of Energy Storage Technology: Metal Organic Frameworks

Abstract

For last fifteen years energy has been transferred by using electricity and as an energy carrier media electricity has some disadvantages like its wire need for transportation and its being non-storable for large amounts. To store more energy safely and for transportation it easily, new storing medias and devices are needed. For easy and safe energy transport there are many technologies and some of these contain hydrogen energy. Metal hydrides, carbon nanotubes, metal organic frameworks (MOFs), compressed gas hydrogen and liquid hydrogen can be cited for these technologies that contain hydrogen. 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) has some targets for 2010 and 2015. System gravimetric and volumetric density should be 5.5 % wt and 40 g/L respectively. To meet the DOE 2015 target a novel organometallic valin-Cu(II) complex studied. After synthesis of metal organic framework structured valin-Cu(II) complex, it is characterized by elemental analysis, X-Ray, FT-IR and thermo analytic TG-DTG techniques. After characterization, hydrogen storage capacity of complex is determined by HPVA-100 adsorption analyzer.
