Capacitive Deionization (CDI) is an emerging, eco-friendly desalination technology gaining momentum. This review covers key topics in CDI, including electrode materials, cell architectures, selective ion removal, energy consumption, and salinity ranges. Key improvements include optimizing carbon materials with surface functional groups, heteroatom doping, and metal oxide modifications. The use of Faradaic materials has significantly increased CDI’s desalination capacity. Innovations in cell architecture from static to flow electrodes allow for continuous production, boosting energy efficiency and expanding CDI’s salinity range. Future research should focus on ion-selective mechanisms, electrode stability, hydraulic design, and economic and environmental assessments to enhance scalability and practical […]

Shortly after the California Coastal Commission’s stunning rejection of Poseidon Water’s $1.4 billion ocean desalination plant proposal for Huntington Beach, Poseidon’s long—time VP of development, Scott Maloni, quipped on Facebook about the “unjust decision,” which put an end to big ocean desal in California for the foreseeable future.

CAIRO – 29 April 2024: Egypt plans to tender bids for the establishment of four desalination plants at a total cost of $350 million, with some near Ras El Hikma by mid-July, according to Atter Hanoura, head of the Public-Private Partnership Unit at the Egyptian Ministry of Finance. Hanoura added that 17 consortia have qualified for the tender since nearly a year ago, and they will be notified to obtain the tender documents.  (Source)

“We need to talk with a consultant about the desalination project. First, we need to understand why we did not get a response for the global tender and then we can decide on the next move,” (Source)

As California continues to adapt to the impacts of a changing climate, the State must work to identify future sources of safe, reliable water for all. This week, the Department of Water Resources (DWR) released a report identifying future planned desalination projects to help meet the brackish water supply goals identified in California’s Water Supply Strategy: Adapting to a Hotter, Drier Future.
