1. A wind turbine comprising:
a generator;
a system inlet;
a system outlet;
an electrolytic unit electrically powered by the generator to produce hydrogen from an input fluid, wherein the hydrogen produced can be taken out of the wind turbine by the system outlet; and
a safety system controlled by a control unit configured to evacuate the hydrogen out of the wind turbine by a plurality of gas outlets distributed on a platform of the wind turbine and configured to release the hydrogen to the atmosphere; wherein the control unit controls the flow through the gas outlets depending on whether a gas outlet is located at a windward direction or at a leeward direction with respect to the platform for avoiding that the hydrogen spreads over a region of the platform,
wherein the gas outlets comprise a funnel with an opening, the opening of the funnel being configured as an air inlet for introducing air into the electrolytic unit and enhancing an evacuation of the hydrogen.
