The hydrogen-powered Tu-155 prototype made its first flight on 15 April 1988.. A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor.
Some development of technology for hydrogen-powered aircraft started after the millennium and gained track since about 2020, but as of 2022 was still far away from outright aircraft product development. Hydrogen fuel cells do not produce CO 2 or other emissions (besides water). However, hydrogen combustion does produce NO x emissions.

Aircraft fuel tanks are a major component of aircraft fuel systems. They can be classified into internal or external fuel tanks and can be further classified by method of construction or intended use. Safety aspects of aircraft fuel tanks were examined during the investigation of the 1996 TWA Flight 800 in-flight explosion accident.
The Tu-155 was a hybrid, only one of its three Kuznetsov NK-8 engines (they are now called NK-88) was actually powered by hydrogen. [2] The fuel tank was located in the air-blown (or nitrogen) rear compartment. A distinctive feature of the aircraft is that the protrusion of the ventilation system is visible on the tail (near the no. 2 engine).

HY4 is a four seat hydrogen fuel cell powered aircraft. It made its maiden flight on 29 September 2016 from Stuttgart Airport, powered by gaseous hydrogen.It was designed by DLR Institute of Engineering Thermodynamics of the German Aerospace Center, [2] [3] [4] based on the Taurus G4, manufactured by Pipistrel.
The company's main product was intended to be a conversion kit to be retrofitted to existing aircraft to allow them to run on hydrogen fuel. The kits were to consist of hydrogen storage tank modules made by the company, combined with an electric motor made by magniX and fuel cells made by Plug Power. [8]
