Air Liquide has announced the construction of a PEM (proton-exchange membrane) electrolyser with a 20 megawatts (MW) capacity for the production of carbon-free hydrogen.

The 20MW electrolyser will increase the current capacity of the Tier One company’s hydrogen facility in Bécancour, Québec (Canada) by 50%.

The PEM electrolysers, with Hydrogenics technology, will serve the increasing demand for carbon-free hydrogen. The PEM will be the largest globally.

Bécancour’s proximity to major industrial markets in Canada and the US will help ensure North America’s supply of low-carbon hydrogen for both industry and mobility usage.

“This investment will help further contribute toward carbon-free hydrogen supply for Air Liquide industrial and mobility markets in North America and complement the recently announced hydrogen investment for the energy markets in the western US,” said Michael Graff, Executive Vice-President and Executive Committee Member of Air Liquide SA and Chairman and CEO of American Air Liquide Holdings, Inc.

“Both are reflective of the Group’s Climate Objectives: to reduce the carbon intensity of its activities and work with customers towards a sustainable industry and the development of a low-carbon society,” Graff continued.

The new production unit will reduce carbon intensity, compared to the traditional hydrogen production process, cutting emissions of nearly 27,000 tonnes of COper year.
