Siemens Energy and Air Liquide Inaugurate Electrolyser Gigafactory in Berlin

Siemens Energy and Air Liquide inaugurated a cutting-edge electrolyser gigafactory in Berlin, Germany, marking a leap in the mass production of electrolysers. German Chancellor Olaf Scholz, Siemens Energy CEO Christian Bruch, and Air Liquide CEO Francois Jackow pressed the start button to kick off the series production of electrolysers.

The factory, with an annual production capacity of 1 GW, is set to become a cornerstone in the rapid expansion of the hydrogen economy. Siemens Energy and Air Liquide will scale up the production to at least 3 GW by 2025, with potential for further growth.

With a 3 GW installed electrolysis capacity, the factory aims to produce an average of 300,000 metric tons of green hydrogen annually. 

Siemens Energy CEO Christian Bruch emphasized the pivotal role of electrolysers in the energy transition, stating, "There is no energy transition without green molecules." He expressed optimism about the gigawatt-scale production's potential to propel the commercialization of this vital technology.

The Berlin facility, built at a cost of approximately EUR 30 million, utilizes the existing infrastructure of a Siemens Energy site, optimizing production efficiency. The electrolysers, based on proton exchange membrane (PEM) technology, will supply stacks – the core components of electrolysers – to a diverse range of customers, supporting the burgeoning market demand.

The joint venture between Air Liquide and Siemens Energy is already supporting projects like the Air Liquide Normand’Hy 200MW electrolyser in Port-Jérôme, France.
