Ultra-Low NOx SCR Technology for Clean, Compliant Data Center Power Generation
Today’s data centers support mission-critical operations such as artificial intelligence (AI), cloud computing, banking, healthcare, and national security, and are installing larger on-site backup generation systems to ensure consistent uptime and strong resiliency.
As this installed capacity continues to expand, managing nitrogen oxide (NOx) emissions has become a key environmental and permitting concern, particularly as federal, state, and local air-quality regulations grow increasingly stringent.
NOx Regulations Are Tightening for Data Centers Worldwide
NOx is generated during combustion in diesel and gas-fired generators and auxiliary boilers that help maintain uptime during emergencies and testing. As data centers expand, stricter air permits, annual tonnage limits, and Tier 4-equivalent standards are being enforced across North America, Europe, and Asia to protect air quality in densely populated areas.
SCR Solutions Engineered for Data Center NOx Control and Compliance
Environmental Energy Services (EES) focuses on advanced emissions control solutions, highlighted by its proprietary LIMitNOx™ SCR platform, which often achieves over 90% reduction, and is designed for demanding applications such as fast-start generators in data centers and distributed power environments.
