As an eco-friendly fuel, hydrogen has many advantages, including clean emissions. Storing hydrogen, however, proved difficult and dangerous — until now. The Department of energy has achieved a breakthrough nanotech that will allow for the secure storage and transportation of hydrogen.
Hydrogen has potential uses in the road transport industries, in other systems of alt-fuel and fuel cells and aviation, but hydrogen is dangerous, highly flammable stuff (image just the hydrogen fire that destroyed the "Hindenberg" professionally, or hydrogen explosions that damaged nuclear power plants in Japan). Safely store hydrogen for transport needs robust means gas tanks and potentially heavy design, which decrease the efficiency of the complete vehicle. But the work by scientists at Lawrence Berkeley National Lab of DoE have created an entirely new composite material packed with nanoparticles that absorbs the gas in its structure for storage of safer, more reliable.
The trick was to distribute magnesium nanoparticles through a polymer called poly (methyl methacrylate), creating a nanocomposite material. The resulting material is good at quick absorption of gaseous hydrogen molecules in its structure and then quickly releasing it on-demand at "modest", all without oxidizing the metal in the material (other similar solid storage methods for hydrogen involve serious heating and cooling).
Nanocomposites could be packed into a tank of fuel and keep the hydrogen gas in a stable, without taking up too much volume in the reservoir-which means that if the tank was broken in an accident, there would be much less opportunity for rapid release of gas idrogenoed any resulting explosions. Might also work for Pocket-sized fuel cells in the future computers or cell phones.
