Using a $1 million grant from the U.S. Environmental Protection Agency, the Texas Diesel Testing and Research Center at the University of Houston will retrofit Houston Independent School District school buses with a system that attempts to diminish the negative impact their diesel emissions can have on the environment. UH researchers will supervise the installation of Nett Technologies’ BlueMAX Selective Catalytic Reduction System on buses. Then, over the course of the next two years, they will analyze the system’s ability to reduce smog-causing Nitrogen Oxides (NOx) and sooty particles being released through emissions using a series of real-world tests.
