Ultra Portable Green House Gas CEMS

GHG-CEMS with OA-ICOS and Exhaust Gas Dilution

UP-GHG-CEMS: Unrivaled CO2 and CH4 Slip Measurement for Marine Engines.

In an era of tightening environmental regulations and a global push for sustainability, precise measurement and reporting of greenhouse gas (GHG) emissions—methane (CH₄), carbon dioxide (CO₂), and water vapor (H₂O)—from both LNG and conventionally fueled engines (e.g., diesel, heavy fuel oil) are critical for compliance and cost savings. The UP-GHG-CEMS (Ultraportable Greenhouse Gas – Continuous Emissions Monitoring System) empowers you with an unmatched solution for accurate GHG analysis across all engine types, helping you significantly reduce costs associated with purchasing CO2 and CO2e allowances. It combines two industry-leading technologies:

  • ABB/LGR’s OA-ICOS Analyzer: Delivers highly specific, interference-free measurements of CH₄, CO₂, and H₂O at a rapid 1 Hz frequency, ensuring precise data for compliance and optimization. Unlike traditional THC (FID/HFID) methods, which can overestimate CH₄ concentrations by more than 50% in LNG engines due to non-specific hydrocarbon detection, the OA-ICOS analyzer provides accurate measurements for both CH₄ and CO₂ across all fuel types, saving you from overpaying for allowances. Measurement methods are traceable to national and internationally recognized metrology institutes, ensuring global credibility and regulatory acceptance.

  • OXYDAN® DP7900 Dilution Sampling Technology: Provides a pristine sample by reducing the dew point below ambient temperature, removing only particulates, and delivering high-speed sampling (8 m/s) through the sample line. This prevents exhaust gas condensation, clogging of sampling lines, and contamination of analyzer optics and measuring cells, ensuring accuracy comparable to ambient air quality for both LNG and conventional engines. No heated sample lines are required, simplifying your operations and reducing maintenance costs.

This powerful combination delivers exceptional precision and reliability, enabling accurate GHG emissions reporting to meet regulatory requirements, optimize fleet performance, and minimize CO2 and CO2e allowance costs across LNG, diesel, and other fuel-powered engines.

Benefits to Help You Save and Succeed

Slash Allowance Costs with Certified Reporting: The OA-ICOS analyzer, recognized as the gold standard by GHG scientists, corrects CH₄ overestimations exceeding 50% seen in THC (FID/HFID) methods for LNG engines and ensures precise CO₂ measurements for all fuels. Traceability to national and international metrology institutes guarantees credible data to report actual emissions, minimizing CO2 and CO2e allowance purchases.

Power Your AI/ML with Robust Data: High-accuracy, real-time data at 1 Hz drives advanced emissions modeling and fleet optimization for both LNG and conventionally fueled engines, enhancing performance and efficiency.

Streamline Operations with Zero Downtime: Eliminates daily, weekly, or monthly service needs and the use of heated sample lines, reducing operational costs and complexity across all vessel types.

Ensure Superior Sample Quality: OXYDAN® DP7900’s high-speed (8 m/s) sampling, dew point control, and contamination prevention deliver a clean, interference-free sample for LNG and conventional engines, enhancing measurement precision.

Operate Anywhere with Ease: Compact design supports on-board use and easy transfer between sampling points or vessels in a ship pool, providing flexibility across diverse fuel types and operational environments, maximizing ROI.
