<p>The energy management system comprises an electrolysis system (6) with an alkaline electrolysis unit (8) and a polymer electrolyte membrane (PEM) electrolysis unit (10), and a control unit. The control unit is: designed to adapt a total power of the electrolysis system to independently control the electrolysis units; and adapted to vary a power of the PEM electrolysis unit for the adaptation of the overall performance of the electrolysis system. The alkaline electrolysis unit is operable in a capacity range of 25-100% of rated output, and has an adaptation time of 1-5 minutes. The energy management system comprises an electrolysis system (6) with an alkaline electrolysis unit (8) and a polymer electrolyte membrane (PEM) electrolysis unit (10), and a control unit. The control unit is: designed to adapt a total power of the electrolysis system to independently control the electrolysis units; and adapted to vary a power of the PEM electrolysis unit for the adaptation of the overall performance of the electrolysis system. The alkaline electrolysis unit is operable in a capacity range of 25-100% of rated output, and has an adaptation time of 1-5 minutes for power adaptation and a power of 100 KW to 5 MW. The PEM electrolysis unit is operable in a capacity range of 0-300% of rated output, and has an adaptation time of 1-30 seconds for power adaptation and a power of 50-500 KW. Independent claims are included for: (1) an industrial plant; and (2) a method of operating an energy management system.</p> |
