Compact hydrogen storage gets a boost / Lo stoccaggio di idrogeno compatto riceve una spinta. Segnalato dal Dott. Giuseppe Cotellessa / Reported by Dr. Joseph Cotellessa An international team of researchers has used nano-engineering to speed up the charge and recharge cycle of compact, solid-state hydrogen storage materials. Solid metal hydrides are seen as a potential fuel source for powering hydrogen vehicles, but are usually limited by slow hydrogen uptake and release. But scientists from Lawrence Livermore National Laboratory (LLNL), working with colleagues from Sandia National Laboratories, Thailand’s Mahidol University, and the National Institute of Standards and Technology, have developed a technique to overcome this. The researchers found that nanoconfinement – infiltrating the metal hydride within a matrix of another material such as carbon – can have the effect of shortening the diffusion pathways for hydrogen, making the hydride a more efficient
