pwp writes to mention that researchers at the University of New Brunswick are reporting they have found a new method of storing hydrogen gas. The new method is able to condense hydrogen gas into a usable solid under mild conditions. "Hydrogen gas is typically stored under pressure in large metal cylinders, approximately four feet high. These cylinders are heavy and expensive to transport. Since they are under pressure, they also pose a safety hazard. 'We've reached a milestone with our ability to condense hydrogen into a usable solid,' said Dr. McGrady. 'The next step is to produce a safe, compact storage system for the compound that is both lightweight and affordable.' The research is expected to produce reversible hydrogen storage materials that can be processed into a powder for use in limitless commercial applications."
