American-Made Challenges

Waves to Water Prize

The Water Power Technologies Office (WPTO) at the U.S. Department of Energy seeks innovators to design water desalination systems powered by marine renewable energy. The Waves to Water Prize is a five-stage competition that offers up to $3.3 million in cash prizes, with a goal to demonstrate small, modular, cost-competitive desalination systems that use the power of ocean waves to provide clean drinking water for disaster recovery and for remote and coastal communities.

The Powering the Blue EconomyTM Waves to Water Prize seeks to accelerate technology innovation in wave energy powered desalination systems. These technologies hold the potential to deliver clean water to communities for disaster relief purposes, and to remote communities throughout the globe. Over the last two years, the prize has provided innovators a pathway from initial concept to technical design, to prototyping. Now, in the final year of the prize, DRINK Stage finalists will test their systems in partnership with the Coastal Studies Institute at Jennette's Pier to see if these prototypes can provide clean, abundant drinking water using only waves as a power source.
