Air Liquide invests $160 million in Arizona low-carbon hydrogen plant for semiconductor manufacturing

Air Liquide is putting over $160 million into a new ultra-high purity gases plant in Arizona that will supply an advanced semiconductor manufacturer. The facility will produce ultra-pure, low-carbon hydrogen using carbon capture technology. Captured CO2 will be liquefied and purified on site for the customer's needs. The plant is expected to come online in 2028. This investment is part of a larger wave of semiconductor reshoring in Arizona, which has attracted over $210 billion in capital since 2020 from companies like TSMC, Intel, and Microchip Technology. The growing demand for advanced chips to power AI and high-performance computing is driving the need for specialized industrial gases and cleaner production methods. For carbon credit and climate markets, this project demonstrates how industrial gas suppliers are integrating carbon capture into their core operations. The low-carbon hydrogen and captured CO2 represent tangible emissions reductions that could generate carbon credits or support compliance with clean fuel standards.
