Dutch researchers’ findings could treble yield of power from salinity gradients
Physicists at Utrecht University in The Netherlands have calculated that that energy producers theoretically could achieve a much higher yield when generating electricity by a version of so-called blue energy production – which harnesses the energy generated when saline and non-saline water mix. Conversely their findings suggest a much more efficient means for desalinating brackish water.

Capacitive Deionization: Challenges and Opportunities
When new technologies arrive on the scene, various companies and researchers publish their own particular view of their use and value. After a few years, some, like capacitive deionization, achieve a toehold in the industry and are deserving of the more considered look these authors have given them. This article first appeared in the November/December…

CDI low-energy desalination can supply remote communities
There has been a lot of media fuss recently about the work at the Massachusetts Institute of Technology on using graphene sheets in membrane desalination. Equally important work is going on in Australia on using graphene sheets as electrodes for capacitive deionisation (CDI). Supported by the National Centre for Excellence in Desalination, Professor Linda Zou…
