The Russian Federation has started to create a "green" hydrogen engine

Russian engineers are creating environmentally friendly hydrogen engines for industrial applications, Pavel Chupin, general designer of ODK-Kuznetsov, told Izvestia in an interview.

"Experts are now working on the development of promising combustion chambers for "green" gas turbine engines, primarily for ground applications. It is assumed that at the first stage they will be adapted for operation on a mixture of natural gas and hydrogen, and in the future - on pure hydrogen," the specialist explained.

He added that back in the late 1980s, the company developed aircraft engines that used liquefied natural gas and hydrogen as fuel.

These components allow minimizing (in the case of LNG) or "zeroing out" (for hydrogen) the so-called carbon footprint. These projects were ahead of their time, but today they are making a comeback.

For example, Chupin said, as part of one of the research works, a design of the combustion chamber of a gas turbine engine was designed, in which combustion of a mixture of natural gas and hydrogen made it possible to reduce harmful emissions of carbon oxides several times compared to the use of natural gas alone as fuel.
