Some Russian engineers are working on technologies for introducing hydrogen engines into aircraft. This type of fuel has an advantage over aviation kerosene, but there are questions about storage, said Sergey Korobtsev, head of plasma technologies at the Kurchatov Complex of Nuclear Transport Energy Technologies.
According to him, there are currently only two main technologies for introducing hydrogen.
The first is low-temperature combustion in a fuel cell, where chemical energy is converted into electrical energy. But at the current level, it is only suitable for light aviation, at most regional.
The second technology, Korobtsev clarified, is based on burning hydrogen directly in the gas turbine of the engine.
But here problems arise with storage. This is a cryogenic tank on board.
As a reminder, the world's first hydrogen-powered aircraft was the Soviet Tu-155, which flew back in 1988. However, the project was closed after a dozen experimental flights.
