Hydrogen is considered to be the most environmentally friendly and promising type of fuel, including for the space industry. Its main drawback is the storage mode. For example, to produce liquefied hydrogen, it must be cooled to an extremely low temperature. Now a group of Japanese scientists from the University of Wasade has developed a flexible polymer, from which it is possible to make a plastic container for storing and transporting liquid hydrogen.
The polymer was obtained from an organic substance called ketone, also known as fluorene, used to produce drugs against malaria.
From the resulting polymer, it is possible to form plastic sheets that hold hydrogen by electrolytic hydrogenation (absorption of the hydrogen material from the gaseous state) in water at ordinary temperature. When heated to +75 ° C in combination with an aqueous iridium catalyst, the material liberates hydrogen.
The experiments showed that the polymer is safe, easy to handle, strong enough, non-flammable and non-toxic. This means that it is quite possible to make plastic containers for transportation of hydrogen, which can even be carried in your pocket. In the future, there may appear fuel tanks for hydrogen cars and various gadgets, as well as gas storage of hydrogen for heating residential houses.
