The nominated project by ITM Power from South Yorkshire, UK, is a compact plant for the demand-oriented and flexible production of hydrogen and oxygen through electrolysis (power-to-gas). Electricity from renewable energy sources is converted into hydrogen or methane and can then either be used to fuel vehicles or fed into the natural gas grid as methane. Thanks to its compact design, the system can be installed close to the consumer. In addition to an inherent pressure of 80 bar and the compact dimensions, the jury was also impressed by the high system efficiency of 72% and a short start-up time of less than one second. The project thus makes a contribution both to stabilizing the grids and to hydrogen-based electromobility.
