Silver Atena GmbH SILVER ATENA GMBH is a technology and engineering company focused on the development of safety-critical electronics and control systems for hydrogen fuel-cell powertrains. Its broader business is centered on electrical conversion, distribution, protection, control, or system integration, with equipment normally connected to transformers, switchgear, cooling, automation, grid interfaces, and the electrical load of the process being supplied. The company’s equipment is normally one layer of a larger electrical architecture, so system design has to account for the characteristics of both the upstream power source and the hydrogen process or load being supplied. Hydrogen projects use the company’s documented electrical technology for the particular electrolysis, fuel-cell, Power-to-X, hazardous-area, or auxiliary-power functions identified in its portfolio, depending on the supplier’s specialization. Its hydrogen-related products include DC/DC converters, high-speed motor inverters for fuel-cell air systems, and hydrogen-tank control electronics. The company also provides functional-safety, embedded-software, and systems-engineering services for fuel-cell and hydrogen-storage applications. Within the hydrogen value chain, SILVER ATENA GMBH therefore acts as an enabling electrical-technology supplier to plant integrators, electrolyzer and equipment manufacturers, project developers, OEMs, and industrial operators.
