Application of polymeric foams for separation, storage and absorption of hydrogen

To build and operate a “hydrogen economy” in future, it is essential to develop safe and reliable technologies to handle (produce, recover, concentrate, store, deliver, etc.) hydrogen gas. In this work, application possibilities of polystyrene foam were studied and the experiments have proven that closed cell polymeric foams are able not only to separate and store hydrogen, but even to absorb it from gaseous mixtures.
