Product description

Seawards’ Cryo-Separation Desalination System offers a groundbreaking approach to desalinating seawater by utilizing controlled freezing instead of traditional methods like filtration or distillation. This innovative technology cools seawater to low temperatures, forming freshwater ice crystals that are then separated and melted into drinkable water.

Unlike conventional desalination systems, Seawards’ method eliminates the need for chemical additives, avoids brine discharge, and consumes less energy. The system's compact and modular design enables easy installation in coastal communities, ports, off-grid islands, and emergency response zones. Powered by renewable electricity, it is an ideal solution for decentralized freshwater production without harming marine ecosystems.

Seawards incorporates digital monitoring tools to ensure water quality and energy efficiency. With zero liquid waste, high water recovery rates, and minimal maintenance requirements, this system provides a circular and scalable solution to combat water scarcity in an environmentally sustainable manner. Its versatility makes it suitable for various applications, including public infrastructure, humanitarian missions, climate adaptation initiatives, and sustainable tourism projects.

About the Company

Seawards is a French deeptech company founded in 2022 and based in Marseille. As a subsidiary of the Seanergy Group, Seawards develops an innovative and sustainable seawater desalination process based on cryo-separation—a zero-waste, low-carbon alternative to reverse osmosis. The company’s patented technology leverages low-temperature freezing to separate freshwater from salt without chemical treatment or high energy demands. This closed-loop system reduces environmental impact while preserving marine biodiversity. Seawards targets areas affected by drought, water scarcity, and coastal stress, offering compact, modular units adapted for decentralized deployment. The solution is designed for full alignment with France 2030 ecological transition goals and responds to public infrastructure needs. Seawards partners with industrial groups, port authorities, NGOs, and government agencies to test and deploy their solution in real-world scenarios. Its innovation has been awarded and recognized by national research and policy organizations.
