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. 

 

 

 

Who can participate?

In April of 2020, the Solar Energy Technologies Office at the U.S. Department of Energy (DOE) launched the Solar Desalination Prize competition to help achieve the goals of the Water Security Grand Challenge.

Round 1 is underway in the Design Contest.

Round 2 launched in April of 2021.

Questions and concerns on team collaboration

Nov. 22, 2021, 7:19 a.m. PST by NREL Challenge

We have received a couple of questions surrounded collaborations between competitors within the Teaming Phase of the Prize. As stated in the rules document, the goal for the Teaming Contest is to identify a cross-functional team that can develop and successfully validate an operational prototype of a solar-thermal desalination system. However you build that team is entirely your decision – whether you collaborate with other prize participants, utilize the American-Made Network, or find external experts. The strongest submissions will demonstrate a team that has the necessary experience, expertise, and access to resources required to develop the proposed concept into a prototype. Each entry will be evaluated based on the criteria outlined in the rules.
