    Abstract: An off-grid wind turbine system comprising a wind turbine with an electric generator (G) for generating an initial electric power output (AC). An electrolyzer system with a hydrogen electrolyzer (ELT) located inside the nacelle or tower of the wind turbine, so as to generate hydrogen (H) by an electrolysis process. An electric converter system (CNV) serves to convert the initial electric power output (AC) into a DC electric power output (DC) dedicated for powering the electrolyzer (ELT). The produced hydrogen (H) is stored in a hydrogen storage tank (HTK), e.g. located adjacent to the wind turbine. Modules each comprising a converter and an electrolyzer may be stacked to provide the necessary capacity. In some embodiment, a synchronous generator excited by an external exciter (EXC) is used, and in some embodiments a hydraulic torque converter (HTC) is used. In some embodiments an AC to DC converter system involving transformer is used, while in other embodiments an intermediate DC to DC converter is used. By placing the electrolyzer (ELT) inside the wind turbine, a dedicated and compact wind turbine is provided which allows a rather simple and low cost wind turbine especially suited for storing energy in the form of hydrogen based on wind.

    Abstract: An off-grid wind turbine system comprising a wind turbine with an electric generator (G) for generating an initial electric power output (AC). An electrolyzer system with a hydrogen electrolyzer (ELT) located adjacent to the wind turbine, e.g. in a housing separate from the wind turbine, so as to generate hydrogen (H) by an electrolysis process. An electric converter system (CNV) serves to convert the initial electric power output (AC) into a DC electric power output (DC) dedicated for powering the electrolyzer (ELT). The produced hydrogen (H) is stored in a hydrogen storage tank (HTK), e.g. located adjacent to the wind turbine. Modules each comprising a converter and an electrolyzer may be stacked to provide the necessary capacity. In some embodiment, a synchronous generator excited by an external exciter (EXC) is used, and in some embodiments a hydraulic torque converter (HTC) is used. In some embodiments an AC to DC converter system involving transformer is used, while in other embodiments an intermediate DC to DC converter is used. A part of the electric converter system (CNV) may be located in the same housing as the electrolyzer (ELT), e.g. integrated to form a unit. By placing the electrolyzer (ELT) adjacent to the wind turbine, a dedicated and compact wind turbine system can be provided which allows a rather simple and low cost wind turbine especially suited for storing energy in the form of hydrogen based on wind.
