Hitachi Energy has supplied Ovako with a modular eHouse solution for the electrification of a 20 MW electrolyzer in Hofors, Sweden. The project marks the world's first steel plant to use hydrogen for heating before the rolling process. Beyond steel heating, the hydrogen will fuel cell-powered trucks, and surplus heat from the plant will support district heating. Hitachi Energy's delivery includes a modular Grid-to-Stack solution, with components such as transformers, rectifiers, control equipment, and high-current connections to convert alternating current from the distribution grid into the direct current required for the electrolyzer. The company has collaborated on the system's development with Volvo Group, H2 Green Steel, and Nel Hydrogen.
