In 2015 HARC completed a project that identified the primary sources of fine particulate matter or PM2.5 pollutants in Harris County as well as the control measures that can be used to reduce them. Each control measure has a unique efficiency and cost.
Mobile Monitoring of Volatile Organic Compounds in the Eagle Ford Shale
HARC deployed a mobile laboratory equipped with a Geographical Positioning System (GPS), a portable meteorological station, and a Proton Transfer Reaction-Mass Spectrometer (PTR-MS) to perform real time measurements of ambient concentrations of toxic volatile organic compounds in the vicinity of oil and gas sites located on a large private property in the Eagle Ford Shale of South Texas. The HARC microscale air quality model was then used to attribute observed peaks in ambient concentration to specific emission points, such as flares and loading/unloading facilities, and to quantify the associated emissions. The air quality impacts of the inferred emissions were also assessed.

Research Associate, Engine and Emissions Control
HARC collaborated with GRIDbot, Good Company Associates, and City of Houston to provide technical support for the demonstration of the GRIDbot charging station infrastructure.
The electric system is experiencing rapid growth in the adoption of a mix of distributed renewable and fossil fuel sources, along with increasing amounts of off-grid generation.
Advanced engine control strategies and after-treatment control strategies are being developed to meet stringent emissions regulations for large diesel engines.
