Desalination Gets a Graphene Boost

November 13, 2015 by Energy @ MIT

Graphene Technology and Safe Water

With the intensifying drought in California, the state has accelerated the construction of desalination plants. Yet due to high construction and operating costs we’re not likely to see reclaimed seawater represent more than a small fraction of America’s clean water reserves for some time to come.[read more]

Getting the Salt Out

Solving Salt Problems

The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that’s much saltier than seawater, after leaching salts from rocks deep below the surface.[read more]

Can Modular Desalination Provide Cheap, Clean Water and Demand Response Too?

Modular Deslination

The process of desalination isn’t nearly as energy-intensive as it was just a decade ago, thanks to new reverse-osmosis plant designs and nano-structured membranes that have drastically improved the energy efficiency of turning salt water into fresh water.[read more]

Steam from the Sun

Steam and New Materials

A new and innovative material structure developed at MIT generates steam by soaking up the sun. The structure, which consists of a layer of graphite flakes and an underlying carbon foam, is a porous, insulating material structure that floats on water.[read more]

Texas Firm Wins Approval for Wave-Powered Desalination Plant

June 1, 2010 by Tim Hurst

SEADOG can be used for desalination or as stand-alone renewable electricity generators One of the biggest problems of large-scale water desalination plants is that they require tremendous amounts of electricity to operate. There have been breakthroughs in desalination technology that have drastically reduced the amount of energy...[read more]

An electricity generating desalination process ?

August 23, 2009 by Big Gav has a post on research into using microbial fuel cells to desalinate water - Penn State discovers new electricity-generating desal process. Researchers from Pennsylvania State University and China have discovered a new desalination process that has a triple cleantech benefit. The process cleans wastewater, generates...[read more]
