Demand for specialty gases to support the manufacture of photovoltaics in India, and Asia-Pacific more widely, is set to take off in the next few years, creating a market opportunity for specialty gas suppliers that could be worth up to $500m, according to analysis by India-based industrial gas company INOX Air Products.
Nishant Shah, Head of Specialty and Package Gases for INOX Air Products, told delegates assembled on day three of gasworld’s Asia-Pacific Industrial Gas Conference 2025 in Bangkok that solar installs have been growing sharply in APAC in recent years. In 2025 the region accounted for 70% of global solar installs, with 417GW of capacity installed against 597GW worldwide.
“The momentum in Asia-Pacific solar installs is clear right now, and India is seeing the most striking growth,” said Shah. “In 2024, India installed 32GW, which was 14% up on its 13GW of installed solar capacity in 2023.”
The manufacture of solar photovoltaics demands about a dozen different specialty gases, including silane, ammonia, nitrous oxide, hydrogen, boron trichloride, and high-purity oxygen and nitrogen.
