Reliable, real-time emissions monitoring engineered for today’s evolving energy landscape

The means and methods of power generation are transforming rapidly as industries, utilities, and mission-critical facilities work to meet growing energy demand while reducing environmental impact. From large utility power stations to on-site generation data centers, owners, operators, and developers face increasing pressure to ensure reliable electricity, maintain regulatory compliance, and support decarbonization goals.

 

As data centers expand to meet accelerating digital and AI workloads, many now operate like mini power plants, using natural gas, diesel, or even hydrogen-blend generators to ensure continuous operation. These systems create the same emissions challenges found in traditional power generation—NOₓ, SO₂, CO, CO₂, and particulates—making accurate and and reliable periodic and continuous gas emissions monitoring essential for environmental accountability and compliance to federal, state and local regulations with minimized downtime.

 

Thermo Fisher Scientific delivers industry-leading gas analyzers and is a preferred gas analysis provider for customers requiring emissions monitoring solutions. Thermo Scientific gas analyzers are designed to meet EPA performance specifications and methods for emissions monitoring, helping ensure a smooth startup during CEMS performance certification. Their familiarity within the industry, ease of use, and high reliability give operators confidence in their monitoring systems. Our analytical technologies provide the real-time emissions data required for US EPA compliance, process optimization, and transparent environmental, social and governance (ESG) reporting.

FAQs

Power generation systems, including data center generators, typically monitor NOₓ, SO₂, CO, CO₂, O₂, H₂O, and in some cases NH₃ and CH₄, depending on fuel type and regulatory requirements.

Data center generators are subject to emissions regulations during testing and operation, and accurate monitoring supports regulatory compliance, ESG reporting, and environmental accountability.

A CEMS continuously measures pollutant concentrations in exhaust gases to support regulatory compliance, emissions reporting, and operational oversight.

Thermo Fisher offers CEMS, iQ Series gas analyzers (42iQ, 48iQ, 410iQ), and the MAX-iR FTIR Gas Analyzer for emissions monitoring and compliance in power generation and data centers.

A relative accuracy test audit (RATA) verifies CEMS accuracy by comparing its measurements to approved reference methods.

The MAX-iR FTIR gas analyzer provides simultaneous, high-accuracy multi-gas measurements, making it well suited for reference data collection during RATA testing.
