Siemens Energy, Air Liquide eye joint 3-GW electrolysers production by 2025

Germany’s Siemens Energy AG (ETR:ENR) and French industrial gases supplier Air Liquide SA (EPA:AI) are setting up a joint venture (JV) to produce industrial-scale renewable hydrogen electrolysers, with production expected to ramp up to an annual capacity of 3 GW by 2025.

The JV, which is subject to approval by relevant authorities, will support the creation of a sustainable hydrogen economy and an ecosystem for electrolysis and hydrogen technology in Europe, the companies said today.

Siemens Energy will own 74.9% of the Berlin-based JV, and Air Liquide will have 25.1%. As announced earlier this year by Siemens Energy, the factory will also be located in Berlin. It will produce electrolysis modules, or stacks, for both companies to serve their customers and the growing market. Production is expected to kick off in the second half of 2023.

The JV will benefit from the combined pipeline of hydrogen projects of its partners. One of the first projects is a 200-MW scheme of Air Liquide in Normandy, France.

According to the announcement, the stacks, based on proton exchange membrane (PEM) electrolysis technology, “are ideally suited to harvest volatile renewable energy.”

“To make green hydrogen competitive, we need serially produced, low-cost, scalable electrolysers. We also need strong partnerships,” commented Siemens Energy chief executive and president Christian Bruch.

Siemens Energy and Air Liquide first announced they were partnering up on electrolysis and hydrogen in early 2021.
