Canada: 20-MW PEM Electrolyzer World’s Largest Low-Carbon Hydrogen Membrane-based Production Unit Launched

Editor: Ahlam Rais

Air Liquide has developed a new 20 MW PEM electrolyzer which is now producing up to 8.2 tons per day of low-carbon hydrogen in Bécancour, Québec, Canada. The electrolysis unit is equipped with the Cummins technology and is expected to meet the growing demand for low-carbon hydrogen in North America.

Paris/France – Air Liquide has completed the construction of the world's largest PEM (Proton Exchange Membrane) electrolyzer. Supplied with renewable energy, this unit is now producing up to 8.2 tons per day of low-carbon hydrogen in Bécancour, Québec. With this large-scale investment, the Group confirms its long-term commitment to the hydrogen energy markets and its ambition to be a major player in the supply of low-carbon hydrogen.

The new 20 MW PEM electrolyzer, equipped with the Cummins technology, is the largest operating unit of its kind in the world and will help meet the growing demand for low-carbon hydrogen in North America. Bécancour's proximity to the main industrial markets in Canada and the United States will help ensure their supply of low-carbon hydrogen for industrial use and mobility. The commissioning of this electrolysis unit increases by 50 % the capacity of Air Liquide's Bécancour hydrogen production complex.

Challenges for EPC Contractors

With an influx of largescale petrochemical construction projects, EPC Contractors will have to be confronted with challenges such as finding enough capacity and quality of construction manpower, delayed permits etc. which require an EPC strategy to stay competitive in this ever-growing market.

This 12-page Process Insight will discuss the current changes in the EPC business and the impact of these changes on EPC projects. Besides the effect of the Coronavirus as well as the current oil price crash on the contracting industry will also be analyzed and an outlook for the industry will be given.

Compared to the traditional hydrogen production process, this new production unit will avoid the emission of around 27,000 tons of CO2 per year, which is equivalent to the emissions of 10,000 cars per year. The choice of Bécancour is based on two attributes of the site: the access to abundant renewable power from Hydro-Québec and the proximity to the hydrogen mobility market in the northeast of the continent.

Susan Ellerbusch, CEO, Air Liquide North America and Group Executive Committee Member: “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.”
