Air Products, the global leader in the production of gas separation and purification membranes, announced it will invest more than $70 million to significantly expand its manufacturing and logistics center in Maryland Heights, near St. Louis, Missouri.

The investment, which is Air Products Membrane Solutions’ largest ever, is driven by growing product demand in biogas and hydrogen recovery applications, as well as customer needs for the use of nitrogen for the aerospace industry and cleaner fuels for the marine industry.

"We are excited to announce this investment to significantly expand the footprint and production capacity of our St. Louis manufacturing and logistics center. This expansion shows our commitment to continue to be a leader in the energy transition by creating innovative products for a safer, cleaner and more productive world,” said Dr. Erin Sorensen, general manager, Air Products Membrane Solutions. “This expansion also highlights our ongoing commitment to the local community and our talented and motivated employees in the region. We are proud to continue to grow and expand our global manufacturing capabilities in the United States in St. Louis.”

The new manufacturing facility is expected to be in production by the end of 2025 and include the addition of 30 new positions. Currently, about 170 employees work at the St. Louis facility. This expansion follows a previous $10 million investment made in 2023 to increase production capacity at the current facility.

“We’re pleased to see yet another leading and innovative company like Air Products expanding its presence in the St. Louis region,” said Missouri Governor Mike Parson. “The growth of employers like Air Products highlights the value of our state’s ideal business climate, strong infrastructure, and skilled workforce. We look forward to Air Products’ continued success in Maryland Heights as it invests and creates jobs in the area.”

Missouri Department of Economic Development Director Michelle Hataway said, “Air Products’ expansion is the latest example of the incredible business growth that’s helping Missourians prosper in St. Louis. We appreciate this company’s commitment to the community as it creates new opportunities and helps drive economic growth in the region.”
