Renaissance Water qualifies for Tracks A and B of XPRIZE Water Scarcity

Consortium team includes Harmony Desalting, Purdue University, and Bochum University of Applied Sciences. Qualified testing using batch reverse osmosis commences in October.

BOSTON, Sept. 24, 2025 /PRNewswire-PRWeb/ -- XPRIZE Water Scarcity is a $119 million, multi-year prize designed to drive widespread access to clean water by creating reliable, sustainable, and affordable seawater desalination systems. Renaissance Water is pleased to announce that our team has qualified for both Track A (System-Level Innovation) and Track B (Novel Materials and Methods) of the competition.

Today, it is evident: sustainable resource management and circular approaches require extraordinary conditions. To boost recoveries, we must push process boundaries and rethink element design. – Prof. Christine Kleffner, Co-founder & CTO, Harmony Desalting

WATER ALWAYS, FOR ALL: Today, desalination serves less than 10% of the global population (as calculated from a total global desalination capacity of 100,000,000 m3/day and a per capita water consumption of 150 liters/day). This approach is clearly insufficient: 80% of the population suffers from serious water threats to their water scarcity. Desalination must be improved to make a meaningful impact on tomorrow's water challenges.

"We developed the first Batch Reverse Osmosis concept over ten years ago, while we were PhD students at MIT, by asking a simple question: how can we eliminate the largest thermodynamic inefficiencies of reverse osmosis?"

– David Warsinger, Associate Professor of Mechanical Engineering, Purdue University
