Our solutions





An electrolysis system

The electrolysis system is the group of components that ensures operation of the electrolysis stack, which is the central element in which water is split into hydrogen and oxygen using electricity. ANDRITZ is technology open regarding electrolyzers. Currently, we are on the market with AEL (Alkaline Electrolysis) and entering the market with PEM (Proton Exchange Membrane).


ANDRITZ Green Hydrogen unique selling proposition (USPs):

  • Be a major global solution provider for green hydrogen production
  • Deliver by optimized manufacturing and supply chain management
  • Reliable high quality - ANDRITZ as trusted partner
  • Leader in total cost of ownership: competitive CAPEX and low specific energy consumption
  • 100% autonomous plant: remote control
  • Service including performance management and predictive maintenance
  • R&D in coming electrolyzer technologies (AEM, SOEL)


The first industrial electrolyzers were large unpressurized alkaline systems (AEL) installed in Rjukan, Norway, in 1929. The power was supplied by a hydropower station with an initial capacity of 108 MW (established in 1908 – the largest hydroelectric power plant in the world at the time). The purpose of the electrolyzers was to provide hydrogen for a Haber Bosch plant producing ammonia fertilizer. Similar installations followed, mostly in connection with hydropower (Aswan in Egypt in the 1960s, Kariba in Zimbabwe in the 1970s, Cuzco in Peru, and many more). Some of them were in operation until the late 1990s and even early 2000s. 

The ANDRITZ Metals electrochemical history is based on development of the so-called GRAVITEL cell for electro-galvanizing of steel around 30 years ago. At that time, we were the first to use iridium coating on the anode, which is used in the PEM (proton exchange membrane) stack as well today. Moreover, hydrogen is produced in our electro-galvanizing process as a by-product. 

Hydrogen touchpoints along ANDRITZ Business Areas

  • Pulp & Paper: electric power as side stream in the pulp mill (black liquor) as input for electrolyzer, CO2 capture technology (Example) and e-methanol.
  • Metals: green steel industry, stamping and welding solutions for bi-polar plates for fuel cells
  • Hydro: provide renewable energy for a green hydrogen plant
