A collaboration including scientists from Lawrence Livermore National Laboratory (LLNL), Sandia National Laboratories , the Indian Institute of Technology Gandhinagar and Lawrence Berkeley National Laboratory has created 3-4 nanometer ultrathin nanosheets of a metal hydride that increase hydrogen storage capacity. The research appears in the journal Small . There is a need for sustainable energy storage technologies that can address the intermittent nature of renewable energy resources. Hydrogen-based technologies are promising long-term solutions that reduce greenhouse gas emissions.
