A Circular Approach to Desalination


4 years

2022 - 2026





Water scarcity impacts 40% of the world’s population, hindering sustainability and threatening the health of ecosystems around the world. In Europe, water stress already impacts 1/3 of the continent, with climate change impacts threatening future water quality and quantity across the EU and leaving the continent more vulnerable to water shortages.

Seawater (SW) desalination offers an alternative water resource with an abundant supply; however, it is an energy-intensive process resulting in high emissions, further exacerbating climate change, and high costs, limiting the uptake of desalinated water.

Since the 1960s, costs for desalinated water have been declining, with reverse osmosis (RO) emerging as the leading technology. Today, it is estimated that energy costs make up 50-60% of the total cost of producing water. In this context, energy-efficient technologies provide an opportunity to further reduce costs and incentivize desalinated water use.

LIFE INDESAL tackles the challenge of supplying safe freshwater from seawater, contributing to fight climate change and to the shift to the circular economy. The project aims to develop and demonstrate a novel integrated and circular seawater desalination solution with a low carbon footprint that produces multi-purpose desalinated water, renewable energy and resources simultaneously.
