A group of scientists at the University of Southern California (USC) have developed a hydrogen storage system that could make practical, safe fuel cells a reality.
The team at USC have been working to overcome the hazards associated with carrying tanks of the highly flammable gas, by storing the hydrogen in a nitrogen–boron complex, ammonia borane, which can be transported as a stable solid.
In an article published in the Journal of the American Chemical Society this month, the researchers presented a catalyst system that releases enough hydrogen from the safe complex to make it usable as a fuel source.
The scientists claim that the system is air-stable, lightweight, and re-usable, representing a breakthrough in hydrogen storage that could have wide-ranging fuel applications.
