Air Liquide inaugurates world’s largest PEM electrolyser

Air Liquide has completed the construction of the world’s largest proton exchange membrane (PEM) electrolyser, which is now producing up to 8.2 tonnes per day of low-carbon hydrogen in Bécancour, Québec.

In a statement issued last week, the company said that the new 20 MW PEM electrolyser increases by 50% the capacity of Air Liquide’s Bécancour hydrogen production complex.

Air Liquide added that, compared to the traditional hydrogen production process, this new production unit will ‘avoid the emission of around 27,000 tonnes of CO2 per year’.

Susan Ellerbusch, CEO, Air Liquide North America and Group Executive Committee Member, commented: ‘The fight against climate change is at the heart of the Air Liquide Group’s strategy. The inauguration of the Bécancour site in Canada marks an important step in the implementation of this strategy. With this world’s first, Air Liquide confirms its commitment to the production of low-carbon hydrogen on an industrial scale and its ability to effectively deploy the related technological solutions. Hydrogen will play a key role in the energy transition and the emergence of a low-carbon society.’
