Within the framework of the joint research project, “Production of hydrogen from renewable energy sources” an approach for the temporal storage of excess wind energy and the grid integration of renewable energies is being researched at the BTU Cottbus in cooperation with ENERTRAG AG. The Hydrogen Research Center Cottbus and two pressurized alkaline electrolyzer-prototypes will be built for this purpose to investigate the influence of different temperatures and pressures, and to identify the potential for process optimization with the help of modeling approaches and a series of experimental tests. For this purpose, different load profiles of real wind turbines will be fed directly into the prototypes through an adapted control module.
