Bulk industrial gases

Four gas majors own the air-separation plants piped into fabs and smelters, and on-site supply contracts lock buyers in for a decade at a time.

Large-volume gases produced by cryogenic air separation or steam methane reforming for smelting, polysilicon, steel, and semiconductors. On-site long-term supply contracts lock in industrial users. Oligopoly of Air Liquide, Linde, Air Products, and Nippon Sanso/Matheson captures most value.

What the evidence shows

Lead times for new ASUs typically exceed 36–48 months from final investment decision to commercial operation.

Air Liquide operates in a concentrated global industrial gases market alongside a small number of major international peers.

High capital requirements and complex logistics limit new entrants and favor established companies.
