The U.S. Department of Energy Water Power Technologies Office invites you to submit your ideas to develop wave powered desalination systems for the Waves to Water Prize. The Waves to Water Prize is a 4-Stage, $2.5M contest to accelerate the development of small, modular, wave-powered desalination systems capable of providing potable drinking water in disaster relief scenarios and remote coastal locations.

The prize supports the integration of existing and novel wave energy generation technologies with water technologies that can deliver effective, consistent, durable and low-maintenance water delivery systems. The prize seeks to identify the ideal scale of wave energy innovation paired with water technologies that can serve niche markets such as disaster response, and advance the state of both wave energy devices and desalination technologies that could provide value in other markets as the technologies mature.

PRIZE GOALS

The purpose of this prize is to incentivize the creation of wave powered desalination systems that meet the following goals:

  • Flexibility in Varied Wave Conditions: Competitors must develop systems that can survive harsh wave conditions and operate under different wave conditions and different sites without major tuning to ensure operation at a wide variety of locations. All solutions that make it to the DRINK Stage will be evaluated at an open-water test site with an anticipated average- to low-energetic wave resources.
  • Easily Deployed: Systems must be able to be deployed in less than 48 hours, addressing the ability to deploy quickly and easily in a disaster response scenario where there is large uncertainty around site conditions.
  • Ship in a Standard Container: Technologies must fit into a predefined container – approximately 45 x 48 x 42 inches – to standardize the shipping constraints that face many disaster response and recovery scenarios.
  • Deliver Minimum Water Quality: The maximum total dissolved solids (TDS) for this competition is 1,000 mg/L. At the DRINK Stage, competitors will be scored higher if this threshold is exceeded and the water quality is closer to a target goal range of 300 – 600 TDS mg/L.
  • Operate without Environmental Degradation: Brine discharge, or other salt concentration issues from the process of desalinating water will need to be managed without creating environmental issues.

Submission to this Challenge must be received by 9 PM EEST on October 14, 2019
