MOSCOW, 30 Mar. An advanced hydrogen fuel transportation and storage system is being developed by scientists from the Samara Polytechnic University together with colleagues from Germany. According to them, the hydrogen accumulator they studied will make it possible to obtain a safer fuel mixture, the use of which will significantly reduce the costs of hydrogen energy. The results of the study were published in Fuel.
Hydrogen is now widely regarded as an alternative to fossil fuels. There is about three times more energy per unit mass of hydrogen than in gasoline or diesel, and when it is burned, only environmentally friendly water is formed.
However, the transportation and storage of hydrogen involves a long chain of expensive operations, often making the use of this environmentally friendly fuel unprofitable, the scientists explained. -title='In Russia received elements for flexible electronics and «green» fuel'>
Chemists from the Samara State Technical University (SamGTU, Samara Polytechnic University) are working on a new hydrogen storage system in which gas molecules are chemically bonded to organic carriers. According to the scientists, in the last article they were able to analyze the thermochemical properties of benzintolools, one of the most promising classes of hydrogen storage substances.
“In addition to the generally accepted, but expensive and unsafe options for transporting hydrogen in a liquefied or compressed form under high pressure or at very low temperatures, today chemical bonding technologies are being explored in the world. This is an economical and much safer approach,” said the head of the Department of Gas Processing, Hydrogen and Special Technologies SamGTU Sergey Vostrikov.
In a relatively simple reversible reaction, hydrogen is bound by benzene toluenes and some other organic molecules derived from petroleum, the scientists say. The resulting liquid is non-flammable and no more toxic than diesel or other common fuels, and can be transported at any temperature at atmospheric pressure. jpg» media-type=»ar16x9″ data-crop-ratio=»0.5625″ data-crop-width=»600″ data-crop-height=»338″ data-source-sid=»not_rian_photo» class=»»/

The release of hydrogen from such a mixture, according to scientists, is possible both at distribution stations and directly inside special advanced engines. The consistency of the mixture is similar to motor oil.
«Our results will allow the development of technologies for the safe storage of hydrogen and its transportation over very long distances. It can use existing pipelines and other fossil energy infrastructure to do this, abandoning from extremely expensive infrastructure for working with compressed or liquefied gas,» Sergey Vostrikov emphasized. //ria.ru/20220818/samarskiy_universitet-1810380334.html» data->
The study was supported by the Ministry of Science and Higher Education of Russia as part of the state task of Samara State Technical University to create new youth laboratories. The study involved specialists from the University of Rostock and the University of Erlangen-Nuremberg (Germany).
In the future, the research team intends to improve the composition of the organic carrier and select new catalysts for more efficient hydrogen evolution.
