CIMC ENRIC Energy Systems · Technical reference
At a comparable power class (about 500 kW), natural-gas gensets typically emit far less NOx and particulate matter than diesel units, with lower CO and near-zero sulfur. Use the comparison below for early customer discussions; it is compiled from published industry sources and is not CIMC factory-test or certification data.

Why emissions matter in gas-to-power projects
Operators replacing diesel with pipeline gas, LNG or CNG often need a clear, citeable view of air-quality benefits: NOx and PM for local air quality, CO and NMHC for incomplete combustion, and CO₂ / GHG for carbon reporting. Modular natural-gas packages such as CIMC ENRIC containerized gensets are commonly evaluated on that basis alongside fuel logistics and power density.
Exhaust factors at about 500 kW (g/bhp·h)
| Pollutant | Diesel | Natural gas | Natural gas vs diesel |
|---|---|---|---|
| NOx | 3.9 | 0.03 | ~95% lower |
| NMHC | 0.2 | ≈ 0 | ~98% lower |
| CO | 1.2 | 0.59 | ~59% lower |
| PM | 0.07 | ≈ 0 (negligible) | Nearly eliminated |
| SO₂ | Present even with ULSD | Essentially none | Near-zero sulfur |
Source for the g/bhp·h factors: Generac Industrial Energy white paper on environmental advantages of natural-gas generators (about 500 kW appendix). CO₂ / GHG order of magnitude is typically also lower for natural gas than diesel (lean-burn on the order of ~40% lower; rich-burn ~11% lower), depending on engine design.
Indicative long-run comparison
Using the same industry appendix assumptions (about 100 operating hours per year over 20 years), cumulative NOx for a ~500 kW diesel unit is on the order of 6.5 tons versus about 0.05 tons for natural gas; particulate mass for diesel is several tons while natural-gas PM is typically treated as negligible.
