NanoH2O is a Los Angeles-based startup that has developed a new membrane material for use in reverse osmosis (RO) desalination. While RO is an established technology, its economic viability hinges on the properties and performance of the membrane.

Carnegie Wave Energy (Carnegie) is an Australian company that develops and commercializes wave energy technology that can not only provide power but also desalinated water.
Carnegie says it will build the world’s first wave-powered desalination plant that will generate energy as well as fresh water (see CleanTechnica
Lockheed Martin, one of the world’s largest military contractors, has developed a process that company officials say significantly reduces the amount of energy needed to desalinate water, an innovation that could help communities worldwide tackle the growing threat of water scarcity.
Water is always precious. Increased natural gas production is happening ion the US. But natural gas wells have problems: Large volumes of deep water, often heavily laden with salts and minerals, flow out along with the gas. That so-called produced water must be disposed of, or cleaned. Once cleaned it has beneficial reuse in often arid regions.
Israel NewTech reported that IDE Technologies will take part in the building and maintaining of what will be the largest desalination plant in the U.S., using the company’s reverse osmosis technology, under a deal that totals $650 Million for IDE. As reported in Globes, IDE has signed a $150 million contract with one of the largest desalination ventures in the US to plan and supply
Israel has always suffered from water deficiency, a fact which has fueled research and development in the field, and brought about a national practice of education regarding water conservation and advanced water management methods. Today, water management has been transferred to water corporations and the water economy is now based on desalination. Water prices
Solutions to environmental challenges are often laden with paradoxes. Let’s take the case of desalination of sea water to make potable water. It’s becoming more common in some parts of the world, including the Mediterranean region and Australia. But there’s a catch: it’s energy-intensive, therefore carbon
Energy Recovery Inc. (ERI), a company based in San Leandro, California, has developed technology that reduces the amount of energy required for desalination.
The technology does not directly relate to filtering water, but instead harnesses the pressure in the wastewater stream of reverse osmosis systems and transfers that pressure to the incoming feed stream to reduce the
More than $88 billion will be invested in desalination technologies worldwide from 2010 to 2016 as regions face dwindling supplies of freshwater and steep population growth, according to a new report. Declining costs associated with several key desalination technologies — including reverse osmosis — will make saltwater-
Water is the new oil. The $425 billion global water sector remains at the forefront of industrial, geopolitical, and social agendas because of a growing supply/demand imbalance and trends in water scarcity, quality, and safety issues. Only 3% of the world’s water is freshwater available to humans and the environment, and water scarcity is a growing problem. By 2025, it is
“Water, Water everyone, nor any drop to drink”
-Rime of the ancient mariner by Coleridge
We’ve all heard or read that “water is the new oil”, often as a pundit’s shorthand for some market prediction. Drinking water, we are told by analysts and environmentalists, is a rare, limited resource which the world is
Dow Chemical Company, a worldwide leader in the global chemical industry, and sponsor of the 2010 Dow Live Earth Run for Water, has entered into agreements with the new Saudi Arabian King Abdullah University of Science and Technology (KAUST) for developing cleaner, new routes for producing chemical derivatives.
The two are also looking into ways for carbon capture –a method which proposes to suck up and store greenhouse gas emissions.
Although many of the chemicals produced by the American chemical giant are used in the petroleum distilling and petrochemical industries, with much of the company’s “raw material” is coming from Saudi Arabia.
It sits in the middle of a harsh, barren desert, sweltering in searing heat. It has no clean water, its sea is polluted and there is no topsoil, just a covering of sand. It is also the biggest per capita consumer of fuel, massively reliant on cars, power-hungry desalination and air-conditioning. And with all this, can the United Arab Emirate state of Abu Dhabi really succeed in building a new “green city” in the Middle East?
If you can believe visionary people like architect Gerard Evenden (his words above), from the British architectural firm Foster & Partners, yes it can. Billions of dollars are riding on the assumption
Water agencies facing droughts and shortages of freshwater, such as in coastal California, have been turning increasingly to desalination this year.
However, current desalination methods can be expensive and energy inefficient. Watchdog groups prefer water conservation and efficiency efforts, and charge that tapping the oceans for potable water can pollute waterways and kill marine creatures.
Yet could desalination become more viable and efficient? The Global Cleantech 100 list anointed several companies with that aspiration as technology innovators earlier this month.
