Overview

Challenge Overview

Solar Desalination Prize

The Solar Desalination Prize is a competition designed to accelerate the development of systems that use low-cost solar-thermal energy to produce clean water from very-high-salinity water, like water produced from oil and gas extraction. The clean water produced can be used in municipal, agricultural, and industrial applications.

 

 

The Opportunity

According to Environment Protection Agency, the oil and gas industry produces several hundred billion gallons of wastewater annually.  This water can have a salt content that is too high for commercially available desalination technologies. Solar thermal desalination can the solution to treating this water, even in remote locations.

The technologies used in solar desalination can also be used in industrial applications like food processing, chemical production, and mineral processing. Solar desalination systems and many industrial applications like food processing do not require high temperatures, so they utilize lower-cost components than other electricity-producing applications.

 

The Prize Structure

The prize is structured in four phases. Each successive phase is more challenging than the last, with larger prizes and fewer competitors advancing. The challenge requires competitors to make progress on a condensed timeline, form private-sector partnerships, and secure investments to make their ideas a reality. 

By the end of the competition, the teams will have designed their solar-thermal desalination system, obtained the necessary permitting and approval documents, built it, and then demonstrated the operation of their system. The Department of Energy will determine the winner and award a final prize of $1 million in cash.
