Description du projet
Optimiser un concept prometteur de batterie afin de relever les défis de l’eau et de l’énergie
Il est impératif d’améliorer l’accès à l’eau douce, une ressource qui s’amenuise rapidement et est indispensable à la vie sur Terre. Les technologies de dessalement produisent de l’eau douce à partir de l’eau de mer. L’osmose inverse, la technologie la plus utilisée, consomme toutefois d’énormes quantités d’énergie et produit de l’eau douce, mais à un coût très élevé. Il y a un peu plus de dix ans, des scientifiques ont annoncé un nouveau concept qu’ils ont baptisé «batterie de dessalement». Celui-ci extrait les ions sodium et chlorure de l’eau de mer et génère de l’eau douce en utilisant une quantité d’énergie bien moindre que l’osmose inverse. Le projet REDEBA, financé par l’UE, repensera ce concept de batterie afin d’optimiser l’électrode de capture des ions chlorure pour une perte d’énergie moindre et un fonctionnement plus souple.
Objectif
"Better managing energy and water resources along with development of water treatment technologies with low environmental impact and energy consumption has become more essential than ever due to water-energy nexus and growing environmental issues. This is mainly performed by using Reverse Osmosis (RO) technologies. However, RO presents number of environmental drawbacks such as effluents produced associated to the chemical regeneration of membranes. There is a strong necessity of secure and sustainable water supply, thus green technologies for water treatment are needed to safeguard the interests of a sensible use of water resources, to remain in strengthening environmental equilibrium as well as in the economic prosperity. Moreover, ""Climate action, environment, resource efficiency and raw materials Challenge"" in Horizon 2020 presents as one of its aims: positioning Europe as a global market leader in water-related innovative solutions. This project will revamp the Desalination Battery (DB) technology, the original and innovative aspects of the proposal lies in taking up the challenge to shift the knowledge frontier and develop a Cl- capturing electrode. Thus, the aim of this project is to develop a full concept for the next-generation DB, addressing the issue of new materials for anion capturing and cell design, which gives lower energy losses and more flexible operation. In order to do so, development of flexible and anionic electrode materials will be investigated, as well as the impact of operation variables on desalination degree and on energy consumption in dependence of the cell design. The multidisciplinary nature of the project is strong, involving a combination of electrode materials development, electrochemistry and engineering (scaling-up, cell and module design). This project is in line with the EU strategy for the sustainable development of water resources and desalination."
