A very large wind turbine with a rotor diameter of 200 m can generate a maximum of 14 MW output power. We plan to build a hydrogen energy storage system for the turbine with capacity to store the energy of one day of operation of the turbine at maximum power. The system uses an electrolyser to produce hydrogen from water, and is powered locally from the turbine output. The hydrogen is stored in a tank nearby the turbine at 700 bar pressure. Estimate the required size of the storage tank to be used, while taking into account the efficiency of the electrolysis process.
