Solar-powered device generates electricity through ion transport and could lead to low-cost for seawater desalination

By binding photosensitive dyes to common plastic membranes and adding water, chemists at the University of California, Irvine have made a new type of solar power generator. The device is similar to familiar silicon photovoltaic cells but differs in a fundamental way: Instead of being produced via electrons, its electricity comes from the motion of ions. Dubbed the “synthetic, light-driven proton pump” by its creators, the innovation – because of its ionic basis – has the added potential capability of taking the salt out of seawater. “The materials used to make such a device can be dirt-cheap,” said Shane Ardo, […]

Qatar and Sweden are planning to set up a green water desalination project that would use only solar and wind energy – Qatar – Sweden

Qatar and Sweden are planning to set up a green water desalination project that would use only solar and wind energy to treat water and reduce 4,50,000 tons of carbon emission per year. Both countries have agreed to “start technical workshops in near future” on this eco-friendly project that is planned to come up in the north of Qatar.

“Sweden and Qatar are negotiating on a water producing project that will be setup in the north of Qatar and it will use only wind and solar energy to desalinate sea water. My meeting with Minister of Energy and […]

We can repair desalination plants: Govt Namibia

Windhoek —

The Ministry of Agriculture, Water and Forestry has denied reports suggesting it lacks the capacity to fix two solar-powered desalination plants set up to supply potable water to Amarika and Akutsima in the Omusati Region.

The two solar-powered desalination plants in question were donated by the German government in 2013 at a cost of about N$200 million. Deputy permanent secretary in the Ministry of Agriculture Abraham Nehemia this week said government had enough competent people with the skills needed to repair the plants. His response came after the Namibian Sun reported last week that Nehemia […]

In this work, for the first time, researchers utilize living organisms – mushrooms – to generate steam under sunlight. It turns out that the micro- and macrostructures of mushrooms possess all the needed characteristics for a good solar steam-generation device: high solar absorption; efficient water supply and vapor escape; and good thermal management. Interestingly, a mushroom is an unlikely candidate as it typically lives in the shadow, i.e. it doesn’t get to see sunlight that much.
The mushroom maintains its hydrophilicity before and after carbonization because of its components, which include carbohydrates and proteins; the nitrogen functional groups […]

UAE Water Aid Foundation (Suqia) has partnered with Dubai Electricity and Water Authority (Dewa) to develop a water desalination plant at the Mohammed Bin Rashid Al Maktoum Solar Park in Dubai, UAE.

The project includes the development of a solar reverse osmosis desalination plant with a capacity of 50 m3/day. The capacity generation relies on a hybrid energy system combining photovoltaic cells (100 kW) and power storage system (batteries) with a capacity of 520 kWh.

The cooperation aims to raise awareness on the importance of finding sustainable and effective solutions to serve the drought-stricken areas and to highlight the role of renewable energy in achieving sustainable development, said HE Saeed Mohammed Al Tayer, chairman of UAE Water Aid Foundation and MD & CEO of Dewa.
