Nano-sized hydrogen storage system increases efficiency

Posted by in categories: energy, nanotechnology, transportation

Nice.


Lawrence Livermore scientists have collaborated with an interdisciplinary team of researchers including colleagues from Sandia National Laboratories to develop an efficient hydrogen storage system that could be a boon for hydrogen powered vehicles.

Hydrogen is an excellent energy carrier, but the development of lightweight solid-state materials for compact, low-pressure storage is a huge challenge.

Complex metal hydrides are a promising class of materials, but their viability is usually limited by slow hydrogen uptake and release. Nanoconfinement—infiltrating the metal hydride within a matrix of another material such as carbon—can, in certain instances, help make this process faster by shortening diffusion pathways for hydrogen or by changing the thermodynamic stability of the material.
