Researchers develop improved polymer for hydrogen storage

Cardiff, Wales – Scientists at Cardiff University in Wales have announced the development of an organic polymer capable of storing around three per cent hydrogen by weight. The new polymer is an improvement on one developed previously by the scientists, which was capable of storing 1.7 percent hydrogen by weight.

Professors Neil McKeown, Peter Budd and David Book say their work offers hope of producing an organic polymer in the future capable of storing enough hydrogen to successfully power a vehicle.

“We are excited to report this recent discovery by our research team of a polymer which can hold around three percent hydrogen by weight,” McKeown says. “Although we still have a long way to go, it is clear that we are moving in the right direction, especially as we also have a number of promising new polymers to test.”

In order to make hydrogen a viable alternative to gasoline, the scientists say a material which can store hydrogen at a weight of over six percent is required. The figure is estimated by the U.S. Department of Energy as the minimum required to make a fuel tank for hydrogen to power a vehicle for 300 miles (483 km).
