Overview

Challenge Overview

Solar Desalination Prize

The Solar Desalination Prize is a four-phase prize competition that will advance thermal desalination technologies to expand the utilization of non-traditional water sources, ensure water security, and improve the resilience of U.S. infrastructure.

The Opportunity

Removing salt from water takes a lot of energy! Many of the largest untapped water resources in the US and around the world cannot be cost-effectively used because of high concentrations of dissolved salts.

Water treatment processes, like reverse osmosis, are efficient when salt concentrations are low, but can’t treat high-salt waters like those that are produced from oil and gas wells, concentrated brines, and some industrial and agricultural wastewaters.

Novel thermal desalination technologies can purify water with very high salt content without dramatically increasing the amount of energy required. By using solar thermal as the energy source, desalination technologies could be used in a variety of important environments, especially in arid areas with high sun exposure, where water purification is especially important.

 

The Prize Structure

The Solar Desalination Prize has a rapid iteration prize structure designed to help entrepreneurs use innovative research to come up with ideas, then design and test concepts, with the end goal of having shovel-ready technology primed for industry adoption.

Millions of dollars in prizes will be awarded over the competition, increasing in value in each phase, culminating in a $1 million grand prize at the end of the competition for successful testing and demonstration of promising solar desalination prototypes.
