Generating electrical energy from hydrogen and oxygen

A method of generating electrical energy from hydrogen and oxygen, comprising an internal combustion engine, a waste heat steam generator (WHSG) which is connected to an exhaust gas duct of the internal combustion engine and which has only one pressure stage, and an H2-O2 reactor, the method comprising:

• feeding the H2-O2 reactor with WHSG steam from the waste heat steam generator, with high-pressure feed water from the waste heat steam generator, with oxygen, and with hydrogen, wherein in the H2-O2 reactor a reaction of oxygen and hydrogen produces additional steam and the high-pressure feed water evaporates into further steam, and wherein the WHSG steam, the additional steam, and the further steam together form a greatly superheated steam that is fed to a steam turbine, and wherein all the WHSG steam exiting the waste heat steam generator is uncooled enroute to the H2-O2 reactor,
• feeding the greatly superheated steam to a steam turbine,
• condensing expanded steam that has exited the steam turbine before the expanded steam that has exited the steam turbine reaches the waste heat steam generator, and
• generating electrical power by a generator connected to the steam turbine, and
• controlling the reaction in the H2-O2 reactor and a steam temperature at an exit from the H2-O2 reactor by spraying the high-pressure feed water as water from the waste heat steam generator into the H2-O2 reactor via a feed water conduit.
