Genset Catalyst Market to Hit $11.79 Billion by 2034 as Data Centers Lift Demand

1 articles · Updated · Straits Research · Jun 12

$11.79 billion is the projected size of the genset catalyst market by 2034, up from $6.96 billion in 2026, implying a 6.8% annual growth rate.
Stricter emissions rules are driving adoption of SCR, DOC and DPF systems, while expanding data centers, industrial backup power needs and wider diesel and gas genset deployment add demand.
Asia Pacific held the largest regional share at 38.42% in 2025, and SCR matched that share among catalyst types; North America is forecast as the fastest-growing region with a 6.52% CAGR.
Data centers are a key growth engine, with that application segment projected to expand at a 9.10% CAGR as AI workloads raise power demand and reliance on backup generation.
