03_Largest PEM(1) electrolyzer in the world, Quebec, Canada

Producing renewable hydrogen on an industrial scale.

By inaugurating the world’s largest PEM(1) electrolyzer in 2021, Air Liquide has reaffirmed its goal of achieving carbon neutrality by 2050. This next-generation electrolyzer is 99% powered by renewable hydraulic energy and produces up to 8.2 metric tons of hydrogen per day, which is enough to power more than 2,000 cars or 230 trucks. It will cut CO2 emissions by 27,000 metric tons per year, which is equivalent to the emissions of 10,000 cars.

04_Low-carbon Air Separation Unit (ASU), China

Building the world’s largest low-carbon ASU for the steel industry.

Air Liquide will build and operate a low-carbon Air Separation Unit in Zhangjiagang City, Jiangsu Province. Designed for Jiangsu Shagang Group, the biggest private steel company in China, this state-of-the-art unit, capable of producing 3,800 metric tons of oxygen per day, will significantly reduce CO2 emissions. By becoming the Group’s largest source of liquid oxygen and nitrogen in China, the unit will supply industrial customers and hospitals in the east of the country. It will also supply krypton and xenon to meet the growing demand of the local electronics industry.
