Siemens Energy and Air Liquide form European electrolyser JV

Firms unveil plan to ramp up PEM stack production at Berlin facility and to collaborate on research and development

German technology company Siemens Energy and French industrial gases group Air Liquide aim to ramp up electrolyser stack production capacity at a facility in Berlin to 3GW/yr by 2025 as part of a green hydrogen joint venture (JV) unveiled today. Siemens will hold a majority 74.9pc share, with the rest held by Air Liquide. The JV is subject to regulatory approval. Production will focus on proton-exchange-membrane electrolyser stacks and will be based at an existing Siemens facility in Berlin that previously produced gas turbines. Initial production is scheduled to start in the second half of next year. “We want to be a driving force in hydrogen technology,” say Christian Bruch, CEO of Siemens
