Abstract (en)
[origin: WO2011012507A1] The generation of gases using electrolysis is known, wherein in the prior art the electrical energy therefor is taken from the grid. According to the invention, the electrolysis occurs as a high-pressure electrolyzer, oxygen being produced on one side and hydrogen on the other side, with corresponding pressure. Said gases may optionally be stored without additional compression. The PEM fuel cell process is used in reverse for the process. It is advantageous that excess energy may be used by wind power plants. In the associated device, a high-pressure electrolyzer (1) is present which is operated using environmentally friendly air power. Due to the improved operating point of the high-pressure electrolyzer, improved economy results for the generation process compared to the prior art, in particular for hydrogen as an energy storage means.
