KAILUA-KONA, HAWAII—The Natural Energy Laboratory of Hawaii Authority (NELHA) is set to receive a $2 million award from the U.S. Department of Energy Solar Energy Technologies Office (SETO) to advance solar-thermal desalination technologies, which can reduce cost and expand the market for creating freshwater from otherwise unusable waters.

The project at NELHA will demonstrate improvements to thermal desalination technologies and low-cost integrated designs for solar-thermal collection and storage to reduce the cost of desalination at its Hawaii Ocean Science and Technology Park (HOST Park) on the Island of Hawaii.
