Title: Progress in Research of High-Density Hydrogen Storage Materials
Abstract: Hydrogen is a clean fuel and hydrogen energy is one type of new energy with tremendous potentials.The bottleneck of hydrogen energy development at the present stage is hydrogen storage,methods of which include high-pressure gaseous storage,low-temperature liquid storage and solid-state storage,but the former two cannot reach future storage goals.Solid-state storage can store hydrogen in solid-state materials through chemisorption or physisorption,which is considered as the most promising way of hydrogen storage due to its high energy density and safety.High-density hydrogen storage materials consist of lightweight elements such as alanates,borohydrides,amido hydrides,ammonia borane,and etc.,exhibiting high theoretical hydrogen storage capacity of more than 5%(mass fraction).Recent developments of high-density hydrogen storage materials are reviewed,and high-density hydrogen storage,close-to-room temperature operation,controllable storage/release of hydrogen,and long-life lightweight hydride materials are believed to reach the goal for hydrogen storage applications as required by fuel cells and mobile hydrogen sources.
