Electrolysis is an important component of hydrogen production from renewable sources (wind, sun, water). By using our water-cooled rectifiers of the EPS/HC5000-WC series, we have succeeded in optimizing the combustion process in power plants. On the one hand, we achieve higher productivity and reliability and, on the other hand, lower energy costs and lower CO² emissions. For these and other applications, we can supply capacities of up to 2 MW.
