Jacobi, Wang receive Department of Energy funding for solar desalination
They are co-principal investigators of a project titled “Ultra-Compact and Efficient Heat Exchanger for Solar Desalination with Unprecedented Scaling Resistance,” which will design, develop, and test novel coatings for heat exchanger surfaces in high-temperature thermal desalination applications which aim to increase heat exchanger efficiency by 150 percent or more than current state-of-the-art technology. This will help address challenges like fouling and scaling as well as corrosion resistance that occurs at temperatures above 200 °Celsius.
Jacobi is the Kritzer Distinguished Professor and Department Head in MechSE. Wang is a research assistant professor.
The MechSE professors’ grant was part of $21 million total funding for new projects to advance solar-thermal desalination technologies. These 14 projects are focused on reducing the cost of solar-thermal desalination and helping the technology to reach new markets, including to areas that are not connected to the electric grid.
Desalination treats seawater, brackish water, and contaminated water for use in municipal and industrial water supplies, or to serve other reclamation needs. Today’s desalination operations need to be grid-connected, limiting their applications to areas with electricity access. Solar-thermal power, which concentrates sunlight and converts it into heat, has the potential to expand access to desalination by enabling smaller, more portable systems that don’t have to be grid-connected.
Four markets that are particularly attractive for solar desalination technologies include: municipal water production, agriculture, industrial processes, and the purification of water produced from energy development, including oil and gas extraction.
Projects that address challenges for small-scale plants that process low-volume, high-salinity water, like brine from oil and gas operations, target an LCOW of $1.50 per cubic meter. Projects that address challenges for large-scale plants that process high-volume, low-salinity water, like sea water for a municipal utility, are expected to target a leveled cost of water (LCOW) of $0.50 per cubic meter.

- Columbia University (New York, NY) $1 million
- Fraunhofer USA Center for Energy Innovation (Storrs, Connecticut): $800,000
- GreenBlu (Hamilton, New Jersey): $1.6 million
- Lawrence Berkeley National Laboratory (Berkeley, California): $800,000
- National Energy Laboratory of Hawaii Authority (Kailua-Kona, Hawaii): $2 million
- Oregon State University (Bend, Oregon): $2 million
- University of California: Los Angeles (Los Angeles, California): $2 million

The projects are anticipated to last up to three years and will be awarded as cooperative agreements, which requires between 20 to 50 percent cost share. Cost share requirements ensure maximum return on taxpayer-funded research and development. In total, the projects represent a public-private investment of nearly $30 million.
