Scientists used neutron scattering to study how tweaking the ionic clusters in ionizable polymer solutions affects their structure. The polymer building blocks are marked in gold and the ionizable groups in red. Findings could open doors to lighter, more efficient clean energy devices.

To further the potential benefits of the nation’s hydropower resources, researchers at 91°µÍø have developed and maintain a comprehensive water energy digital platform called HydroSource.

ORNL researchers worked with partners at the Colorado School of Mines and Baylor University to develop a new process optimization and control method for a closed-circuit reverse osmosis desalination system.

91°µÍø scientists worked with the Colorado School of Mines and Baylor University to develop and test control methods for autonomous water treatment plants that use less energy and generate less waste.

Urban climate modeling

Researchers at 91°µÍø have identified a statistical relationship between the growth of cities and the spread of paved surfaces like roads and sidewalks. These impervious surfaces impede the flow of water into the ground, affecting the water cycle and, by extension, the climate.

Sometimes conducting big science means discovering a species not much larger than a grain of sand.

While Tsouris’ water research is diverse in scope, its fundamentals are based on basic science principles that remain largely unchanged, particularly in a mature field like chemical engineering.

Water and energy are inextricably linked, yet in our 20th-century water systems we use freshwater once then throw it away. With innovations designed to enhance desalination technologies, agricultural runoff, produced water from industry, and inland brackish groundwater that are now seen as untreatable could all be sources of clean, safe, and affordable water.

The National Alliance for Water Innovation, a partnership of the Department of Energy’s 91°µÍø, other national labs, university and private sector partners, has been awarded a five-year, $100 million Energy-Water Desalination Hub by DOE to address water security issues in the United States.

Desalination process

A new method developed at 91°µÍø improves the energy efficiency of a desalination process known as solar-thermal evaporation.
