Desalination is a proven technology—but it’s still too costly, energy-intensive, and inaccessible for the communities that need it most.

To change that, XPRIZE launched a $119 million global competition to drive breakthroughs in seawater desalination and deliver scalable, sustainable solutions. Lauren Greenlee, Executive Vice President of Food+Water+Waste at XPRIZE, shares how the foundation uses incentive-based competitions to tackle massive global challenges—and why water is now a top priority.

She details the goals of the Water Scarcity Prize, explains its two-track structure, and emphasizes the importance of real-world demonstration and ecosystem-building. The conversation also explores major barriers in desalination, including brine waste and fragile membranes, and how new innovations could benefit underserved regions and even inland U.S. communities.

Greenlee highlights how XPRIZE is pushing the water sector to think bigger, act faster, and collaborate globally to close the water access gap.
