Invented material for hydrogen storage. Bashny.Net

Hydrogen has great potential as a future source of clean energy. The problem is that hydrogen gas is difficult to securely store and transport. The intensity with which it burns, is made of liquid hydrogen fuel for the space industry, and for this it needs to be liquefied at very low temperatures. Currently, the Japanese research team has invented a compact, flexible polymer that can be used to create the plastic container in which hydrogen can be safely worn even in the pocket.

Researchers worldwide have searched for a long time the best way to store hydrogen, for that would be more widely used as a fuel source. At this stage the focus is on the development of compact hydrogen storage for automotive industry and for other small mobile devices. Modern cars with hydrogen fuel cells like the Honda Clarity Fuel Cell does not burn hydrogen, but chemically converts hydrogen gas with oxygen from the air to generate electricity, with the hydrogen stored in expensive reservoirs under high pressure, which are designed to withstand extreme loads.

This is where the new polymer will find use for it? The researchers of Waseda University (The Waseda University) will soon prove that their new ketone — alcohol polymer safe even when filled with gaseous hydrogen.

The discovery was based on recent research vodorodopodobnykh organic compounds that have shown potential as a practical method of hydrogen storage, because the connections can safely and reversibly store hydrogen by the formation of chemical bonds with it.

The material found in the Waseda University, was established through the development of polymer of ketone, called fluoren — organic compound, which is used for the production of anti-malarial drugs.

The polymer can be cast in the form of a plastic sheet, and can detect hydrogen through a simple electrolytic hydrogenation at — 1.5 V (compared to Ag / AgCl) in water at room temperature. When heated to 80 ° C (176 ° F) with liquid iridium catalyst, Flournoy polymer releases hydrogen.

Thus, there is reason to look to the future with optimism — obtained polymer is safe and simple to use, easily takes the desired shape, durable, non-flammable and has low toxicity. It can be done through repetitive cycles of fixation and hydrogen evolution in mild conditions without significant losses.

This means that in the future the polymer can be used to create plastic containers for hydrogen that you can carry in your pocket. His potential is impressive — for example, it can be used in the transportation of hydrogen and the use of cartridges as a fuel source for vehicles and other devices, as well as to create systems of hydrogen supply for homes, businesses and remote research bases on the moon or Mars ... published
