Work is underway in Eastern Europe to produce alternative modes of air travel using cryogenic fuels, as Russian scientists perform huge research, construction and experimental work on creating alternatively-powered civil aircraft.

In efforts to move away from the traditional kerosene, scientists have already tested liquefied associated petroleum gases (condensed aircraft fuel), as well as LNG and liquid hydrogen, according to a report by Russia IC.

All such alternative fuels are thought to be cheaper than traditional kerosene and do less harm to the environment, while perhaps also symbolic of the drive towards a cleaner energy future.

Engineers have reportedly built a unique aircraft, the’ Tu—155’ which is the first flying vehicle in the world, using cryogenic fuels. The vehicle has already performed over 60 flights, including a voyage to Europe.

Newest modifications of ‘Tupolev’ aircrafts operate on alternative fuels, while developers emphasise that reconfiguration of fuel tanks requires minimal costs, the report suggests.
