PEM gigafactory inaugurated

4 January 2024



Siemens Energy and Air Liquide have inaugurated their electrolyser gigafactory in Berlin (pictured). With the new factory, Siemens Energy says it is laying the foundation for the ramp-up of the hydrogen economy, noting that for hydrogen to become the game changer for a climate-neutral future, it must be available in large quantities and at competitive prices. This requires serial production of cost-effective and scalable electrolysers. With an annual production capacity of one gigawatt, Siemens Energy and Air Liquide expect a ramp-up to at least three gigawatts by 2025 with potential for more.

The new 30 million euro facility will supply stacks based on proton exchange membrane (PEM) technology, which is described by Siemens as “being particularly good at following intermittent renewable energy supply.”

“There is no energy transition without green molecules,” said Christian Bruch, CEO Siemens Energy. “With today’s opening and the start of gigawatt-scale production of electrolysers, we are launching the next step for the commercialisation of this vital technology. Now we need to agree on a viable business model with a balanced risk and reward profile.”
