ARC Advisory Group’s new research on the Emission Monitoring Systems (EMS) market highlights how industrial decarbonization initiatives and expanding carbon capture investments are increasing the importance of Emission Monitoring Systems for compliance, carbon accounting, and capture-efficiency verification. CO2 capture is driving the evolution of CEMS by increasing the need for accurate, real-time monitoring of emissions before and after capture. CEMS support not only regulatory compliance, but also carbon trading and verification of capture efficiency. They are now used at key points in carbon capture infrastructure, including flue gas streams, pipelines, and storage sites. As a result, CO2 capture is making CEMS more critical and technically advanced in the push for industrial decarbonization.
"Global environmental challenges require collaborative solutions from governments, industries, and environmental organizations. The Emission Monitoring Systems market is seeing more cooperation to create uniform monitoring protocols, exchange best practices, and apply emission reduction strategies on a global level. This trend highlights the shared responsibility in fighting climate change and reaching sustainable development goals," according to Vidya Prasad, Research Director, Process and key author of ARC's Emission Monitoring Systems Market Research.
Emission Monitoring Systems Market Trends
In addition to providing detailed competitive market share data, the research also addresses key market trends as follows:
End Users Exhibit a Preference for Extractive CEMS
End users exhibit a preference for extractive CEMS due to ease of calibration, but the market is showing a trend toward greater use of in situ CEMS. Though complex, in situ CEMS does not require sample conditioning, a major advantage over extractive CEMS. Another advantage is the ability to measure gases such as NH3 and nitrogen dioxide (NO2). As many plants are installing deNOx systems, they require a system that can measure NH3. For in-situ CEMS, the most common technique is single-point measurement using a probe.
Companies Opting for CEMS that Utilize Fourier Transform Infrared Spectroscopy (FTIR) CEMS
A growing number of plants are now choosing CEMS that utilize Fourier transform infrared spectroscopy (FTIR), as this technique can measure multiple gases without requiring frequent calibrations. In situ systems are also getting more popular as these can measure ammonia (NH3) gas. Multi-component products will reduce the cost of ownership with connected world (Internet of Things solutions), and sensitive products are required due to reduction in emission limit values with complete solution.
PEMS Provides a Cost-Effective Alternative to CEMS
PEMS provides a cost-effective alternative to CEMS, a contributing factor in the growth of PEMS. Although now approved for use in lieu of CEMS by the US as well as few European and Middle Eastern
countries, adoption of PEMS remains slow. A major reason for slow adoption is the limited applicability of the PEMS. PEMS cannot replace CEMS for all applications. PEMS is most suitable in applications with a constant quality fuel source, making natural gas-fired plants the most likely prospects.
Global Collaboration for Emission Reduction
Global environmental challenges require collaborative solutions from governments, industries, and environmental organizations. The EMS market is seeing more cooperation to create uniform monitoring protocols, exchange best practices, and apply emission reduction strategies on a global level. This trend highlights the shared responsibility in fighting climate change and reaching sustainable development goals.
Changing Regulatory Landscape
Emission regulations are constantly changing, as governments around the world implement more stringent measures to fight against global warming and air pollution. This creates more opportunities for the EMS market, as they need solutions that can meet the current requirements and also adjust to future ones. Companies in this market are developing technologies that give complete data for
regulatory reporting.
