Gas Turbine Emission Reduction Systems

T-SCR

The shifts to renewable energy sources such as wind and solar require the modern power grid to adapt, becoming more flexible and responsive to meet evolving market demands. Open cycle gas turbines (OCGT) are essential in providing the flexibility and expediency required, but their NOx emissions pose significant challenges. The NEM Selective Catalyst Reduction system using tempered air (T-SCR) offers a robust solution, allowing gas turbines to provide reliable and flexible power to the grid while complying with strict environmental emission regulations. By effectively reducing OCGT emissions to the most stringent NOx requirements, achieving NOx levels as low as 2.0 ppm, our T-SCR system ensures clean, reliable energy, seamlessly stepping in when renewable sources fall short, and ultimately creating a healthier, more resilient power grid.
