Research on hydrogen-fueled cars may be one step closer to application thanks to a new form of hydride discovered by scientists at the ESRF. The material, lithium borohydride, is a promising energy storage system: it contains 18 weight percents of hydrogen, which makes it attractive for use in hydrogen-fueled cars. Its drawback is that it only releases hydrogen at quite high temperatures (above 300C). The team has found a new form of the compound that could possibly release hydrogen in mild conditions. This discovery was completely unexpected from the point of view of theoretical predictions.
Automotive industry regards hydrogen as a perspective energy carrier. If a good hydrogen storage material will be developed, the petrol in cars can be replaced by clean hydrogen energy. Five kilograms of hydrogen would take you as far as twenty liters of petrol.
The rest of the article is pretty technical and over my head, but it seems that this discovery defies limitations on hydrogen as a fuel source that were previously accepted as conventional wisdom.
