Examining plant cycles and testing new efficient processes, not only can reduce water intake, but also lower overall operating costs. Identifying, and treating alternative sources of water, such as brackish, and effluent streams, offers opportunities for scientists to address energy-water system challenges. The complex relationship between energy and water is constantly developing.
Linking reclaimed water with power generation: Water reuse and the energy-water nexus
The multiple components that impact the system can be modeled and analyzed to better inform decision-makers, and scientists alike. This area helps prioritize research objectives through thorough analyses of the water-energy system behavior. The diagram explains the movement of water throughout the plant and highlights key technologies where water efficiency can be improved.
Cooling Research Heats Up
Assessing the Energy-Water Nexus, and providing new technologies for efficient energy production Water is a fixed resource with competing demands and increase uncertainty. Increasing Water Efficiency and Reuse With the inextricable link between water and energy, it is increasingly important to use water effectively through the power generation sector. Treatment of Alternative Sources of Water Identifying, and treating alternative sources of water, such as brackish, and effluent streams, offers opportunities for scientists to address energy-water system challenges.
Energy-Water Analysis The complex relationship between energy and water is constantly developing. A short video showing freezing and thawing of the PCM in this sink is shown below. Initially, the PCM is frozen.

Heat is supplied to the evaporator surface, causing all of the temperatures to rise. After the PCM is melted, the temperatures start to rise more quickly due to sensible heating. The heater was turned off after 8 hours had elapsed, and the PCM began to recharge. Some supercooling occurred, so the PCM froze at a colder temperature than it melted roughly 9 hours after the start of the experiment.
One of the main research focuses of this project was solving the subcooling issue, which was completed for the large scale prototype.

Reports & Software
A loop thermosyphon connects the evaporator and air-cooled radiator to the PCM heat exchanger. A series of valves allows each section of the loop thermosyphon to operate independently during the melting and freezing operations.

To meet the project goals, the PCM heat exchanger was designed for the melting process to finish in 10 hours. The results of this effort are seen in Figure 6.
In section 2, the PCM was remixed by melting all present hydration levels, which led to stability of the PCM solution. Further testing is required to qualify the system for industrial applications. Figure 5.
