Air Liquide completes world’s largest electrolyser
The French firm made a strategic shift to low-carbon hydrogen and is engaged in several large-scale projects around the world
French industrial gases giant Air Liquide completed construction of the world’s largest proton exchange membrane (PEM) electrolyser system to produce green hydrogen in Quebec on 26 January. It was a small but important step in the company’s goal of becoming a leading supplier of low-carbon hydrogen and related technologies to the world. It has committed to provide only low-carbon hydrogen for the mobility market as of 2030. The 20MW PEM electrolyser will be made up of four 5MW modules provided by US-based engine maker Cummins. It is twice as large as the previous record holder in Fukushima, Japan—opened last March—and boosts hydrogen capacity at Air Liquide’s Becancour plant by 50pc. B
