Company says technology helps achieve World Bank Emissions Standards

GE said it has added selective catalytic reduction (SCR) technology to its mobile aeroderivative gas turbines, a move that helps surpass stringent World Bank Emissions Standards.

The first such system was installed on four GE TM2500 turbines at the Department of Water Resources (DWR) sites in Yuba City and Roseville in California, USA. According to GE, the solution reduced nitrogen oxide (NOx) and carbon monoxide (CO) emissions by over 90%, surpassing World Bank Emissions Standards. It marked the world’s first-of-a-kind solution on a GE mobile TM2500. The technology helped lower emissions while supporting the statewide energy grid during extreme climate-driven events including drought or wildfires.

With the SCR technology, GE’s mobile gas power technology, typically used for emergency use, can meet not only the emissions requirements in line with World Bank Standards, but even surpass them and meet California’s most stringent emissions standard requirements.

“GE’s aeroderivative mobile technology, typically used for emergency power, represents a perfect complement to renewable energy and peaking power use cases worldwide,” said Clive Nickolay, CEO of GE Gas Power’s Aeroderivative business line. “We’re excited about GE’s efforts to provide power plant operators with a technical solution that will allow them to quickly install peak power when needed, while drastically reducing NOx and CO emissions levels to low single digits.

The technical solution includes engineering studies for the integration and installation of a Selective Catalytic Reduction (SCR) technology system. The technology works by removing common emissions through a catalytic converter transforming the nitrogen oxides contained in the exhaust gas into water vapor and nitrogen.

At Yuba and Roseville, GE worked with the engineering, procurement, and construction company Kiewit Power Constructors Co. to install this solution on a GE mobile gas power turbine to solve DWR’s emissions challenge. The emissions control solution includes 11-meter-high modules and a 22-meter-high stack. Each of the four TM2500 can produce up to 34 MW of electricity for a total of 136 MW and is now equipped with a system to reduce pollutants to 2.5 parts per million, the legal limit set by the state of California.
