Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have created a composite material that they claim can store hydrogen densely and safely, yet that also allows it to be easily accessed for creating electricity. Some materials that are currently used for hydrogen storage have a relatively small capacity, and need to be superheated or supercooled in order to work at peak efficiency. The new material, however, is said not to have either of these limitations.
