 "summary": "Bulk and specialty industrial gases — nitrogen, oxygen, hydrogen, argon and others — used in chip fabrication, laser manufacturing, and fire suppression systems.",
 "description_md": "Industrial gas companies supply a wide product line that touches the data-center chain at several unrelated points. Bulk and ultra-high-purity gases are consumed inside semiconductor fabs during chip manufacturing (upstream of Layer 1), specialty gas mixes are used in the lasers that manufacture optical components and in laser-based processes elsewhere in the supply chain, and clean gas-based fire suppression systems protect the data hall itself (Layer 9). These are largely separate end markets served by the same handful of large industrial-gas producers, who typically supply fabs and large industrial sites through on-site or pipeline arrangements rather than open-market sales.\nAI-driven fab expansion — more wafer capacity for GPUs, HBM and networking silicon — is the larger and more direct driver of gas demand here; the fire-suppression use inside the data center itself scales with the count and size of protected spaces rather than with chip volume. For investors, exposure runs mostly through the fab-buildout cycle (on-site gas supply contracts are long-dated and tied to specific fab expansions) rather than through data-center construction directly, with the suppression-system side a smaller, steadier adjacent market.",
 "ai_delta": "AI accelerator, memory and networking-chip demand is driving fab capacity expansion, and each new or expanded fab brings a long-dated on-site industrial-gas supply contract with it.",
