Dutch chemist Kees Baldé has demonstrated that hydrogen can be efficiently stored in nanoparticles. This allows hydrogen storage to be more easily used in mobile applications. Baldé discovered that 30 nanometre particles of the metal hydride sodium alanate make the favourable extraction and storage of hydrogen possible.

A new breakthrough in hydrogen storage technology could remove a key barrier to widespread uptake of non-polluting cars that produce no carbon dioxide emissions.
