Wave2O Desalination System
Resolute Marine
Solution Overview & Benefits
Wave2O™ uses wave energy converters installed just offshore to pressurize seawater and feed it directly into a reverse‑osmosis desalination plant onshore—without using electricity. It’s designed for coastal and island communities lacking reliable power, providing dependable and low-cost freshwater. The system is modular and quick to install, with minimal environmental impact, making it ideal for remote, water-stressed regions.
Benefits:
- Zero fossil fuel use—powered entirely by ocean waves (no grid needed)
- Low freshwater cost—around €1.20–$1.25 per cubic meter, typically 3× cheaper than diesel-based systems
- Scalable & rapid deployment—modular units fit in shipping containers and can be installed in days
- Minimal environmental footprint—brine discharge is highly diluted and safe; no visual or noise disruption
- Local jobs and skills—operation and maintenance create opportunities in target communities
- Reduces CO₂ emissions—each 4,000 m³/day unit displaces about 5,500 tons of CO₂ annually, equivalent to removing ~1,050 cars from the road
History & Development
Resolute Marine Energy (RME), based in Boston, Massachusetts, began developing wave-powered desalination technologies in the early 2000s with support from the U.S. Department of Energy and other partners. The Wave2O™ system evolved from RME’s early work in wave energy converters, adapting this technology to address freshwater scarcity in off-grid coastal areas.
In 2018, Wave2O was selected by the Solar Impulse Foundation as one of their 1000 efficient and sustainable solutions. Pilot projects have been pursued in several countries, including Cape Verde, Morocco, South Africa, and various island nations. The system continues to be refined and adapted for rapid deployment in coastal communities facing climate-driven water stress.
