Scientists create new polymers to carry stored hydrogen
Hydrogen has great potential as a clean energy source in the future. The problem is that it is difficult to store and carry hydrogen safely. A Japanese research team recently invented a compact and flexible polymer that can be used to make a plastic container to store hydrogen and even carry it safely in a pocket. Researchers at Waseda University in Japan have proved that their new ketone/ethanol polymer is absolutely safe for storing hydrogen. The researchers found an anthrone, an organic compound used in the manufacture of anti-malarial drugs, to make ketone/ethanol polymers.
The polymer can be molded into a plastic film to fix hydrogen at room temperature by means of underwater electrolytic hydrogenation. When the polymer is heated to 80 ° C under the action of a hydroquinone catalyst, the polymer will release hydrogen. At the same time, this hydrogen charging and discharging process under mild conditions is repeatable without significant degradation.
The polymer is non-flammable, has low toxicity and is easy to handle, has a strong plasticity and is strong and not easily damaged. In the future, it is expected to be used to build plastic containers to store hydrogen so that it can be carried in people's pockets. The most likely application is the fuel cell in the automotive sector, and it can also store spare hydrogen energy for the family at any time.
