A hydrogen containing nanostructure is provided, where the hydrogen is adsorbed to the nanostructure by physisorption. The nanostructure includes light elements, selected from the second and third rows of the periodic table. The nanostructure is formed as a layered network of light elements coupled

A hydrogen containing nanostructure is provided, where the hydrogen is adsorbed to the nanostructure by physisorption. The nanostructure includes light elements, selected from the second and third rows of the periodic table. The nanostructure is formed as a layered network of light elements coupled with covalent sp2bonds. The chemical composition of the nanostructure can be such that the desorption temperature of hydrogen is greater than the liquefaction temperature of nitrogen, 77 K. Further, a hydrogen storage system is provided, including a container and a nanostructured storage material within the container, wherein the nanostructured storage material includes light elements, and the nanostructured storage material is capable of adsorbing hydrogen by physisorption. The hydrogen storage system can include a liquid nitrogen based cooling system, capable of cooling the nanostructured storage material below the desorption temperature of hydrogen. Some embodiments contain a heater to control the temperature of the nanostructured storage material.
