Hydrogen recuperation for vehicles

A method (100) for converting and/or storing electric energy E obtained from mechanical energy M in a vehicle comprising a motor (1), wherein the mechanical energy M is obtained when braking and/or during an overrun operation of the vehicle, the method comprising

• a) converting the mechanical energy into electric energy E in a first step using a generator (2),
• b) storing the electric energy in an intermediate energy store (3) in a second step,
• c) discharging the stored electric energy E to an electrolysis module (4) in a third step,
• d) having the module convert the electric energy E into chemical energy C in a fourth step at least by splitting water (H2O) into hydrogen (H2) and oxygen (O2), and
• e) conducting the chemical energy into a gas tank (5) of the vehicle for temporary storage in a fifth step.
