The Electrochemical Society Interface • Fall 2004 ydrogen storage is a crucial step for providing a ready supply of hydrogen fuel to an end use, such as a car, as it is considered by many to be the most technically challenging aspect of achieving a hydrogen-based economy. Current hydrogen storage materials or systems are still far short of meeting target goals set for either 2010 or 2015. Two k...

As a kind of cost-efficient hydrogen storage materials with high hydrogen capacity and light weight, Mg-based alloys have attracted much attention. This review introduces an effective technique in producing bulk ultrafine-grained (UFG) Mg alloys and promoting its hydrogen storage property, namely, equal-channel angular pressing (ECAP). This paper briefly describes the technical principle of ECA...

Hydrogen-based fuel cells are promising solutions for the efficient and clean delivery of electricity. Since hydrogen is an energy carrier, a key step for the development of a reliable hydrogen-based technology requires solving the issue of storage and transport of hydrogen. Several proposals based on the design of advanced materials such as metal hydrides and carbon structures have been made t...

Extensive research has been carried on the molecular adsorption in high surface area materials such as carbonaceous and MOFs well atomic bonded hydrogen metals alloys. Clathrates stand among ones to be recently suggested for storage. Although, simulations predict lower capacity than expected by DOE norms, additional benefits of clathrates low production operational cost, fully reversible reacti...

Science, technology and politics agree: hydrogen will be the energy carrier of future. It replace fossil fuels based on a sufficient supply from sustainable energy. Since possibilities storing transporting play decisive role here, so-called LOHC (Liquid Organic Hydrogen Carriers) can used as materials. materials reversibly absorb hydrogen, store it without loss release again when needed. little...

Silicon-hydrogen crystalline models are proposed to estimate theoretical hydrogen storage capacity in porous silicon media with nanostructure features like cubic nodules, columnar forests and thin wall honeycomb like networks. To simulate these nanostructure features and their hydrogen storage capacities, three basic crystalline types (cubic, column and plate) have been developed as building bl...

This project aims to develop new porous hydrogen storage materials which utilize molecular chemisorption of hydrogen rather than mere physisorption, and ultimately do this in low weight hybrid materials. Stronger binding of hydrogen should result in greater capacity and lower operating pressures at room temperature. These studies should lead to the design and synthesis of hydrogen storage mater...

The goal of this project was to develop a high-density hydrogen storage system based on ammonia borane (AB) complex. Due to their high hydrogen capacity, AB hydrides have been employed as disposable hydrogen (H2) sources for fuel cell applications. The objectives of this project were to 1) identify viable amine-borane (AB) complexes for hydrogen storage at ambient conditions, and 2) develop a c...
