South Africa and Iran have partnered to develop desalination plants along their respective countries’ extensive coastlines.[1]  Both nations are in the midst of intensive drought. 

South Africa is dealing with its most severe water shortages in 30 years.  While the South African Weather Services identifies the source of the drought as El Nino, climate change is also a contributing factor in the lack of rain.  Farmers are losing business, food prices are increasing, and the government has declared 5 of its 9 provinces as “...

In Zambia, climate change has brought about a severe drought that threatens the viability of the hydroelectric Kariba Dam—one of the largest in the world. As reported in the New York Times, when drought previously took hold in the country, the Kariba Dam remained “a steady, and seemingly limitless, source of something rare in Africa: electricity so cheap and plentiful that Zambia could export some to its neighbors.”[1]  The Kariba allowed Zambia’s economy to grow, and also contributed to political stability.  However, the severity...

The Rottnest Island DaisyOn the shores of Rottnest Island in Western Australia, solar energy will soon help to power an existing desalination facility that is undergoing major upgrades. [1] In the spring of 2017, the Rottnest Island Water and Renewable Energy Nexus Project (WREN) will realize its objective to deliver electricity and drinking water for the island at a lower cost and with reduced emissions—by using renewable energy and displacing existing diesel-powered generators. [2]  The WREN Project will add 600 kW of solar power to an existing 600 kW wind turbine that was installed in 2004.  It will also implement a smart control system that will maximise the use of solar and wind energy when it is most abundant, and store treated water for times when renewable energy is not available.

Nanoporous carbonScientists at the Leibniz Institute for New Materials (INM) in Saarbrücken, Germany are further developing an emerging desalination method.  The process, referred to as capacitive deionization (CDI), extracts ions from water using electrodes, generating clean water and ions that have been enriched on the electrodes.[1] This process removes salts and heavy metals and, uniquely, it does not use conventional water treatment methods that rely on chemical reactions or sophisticated filtering methods.

In addition to desalination, Professor Volker Presser, head of the Energy Materials Group at INM, explains that emissions from power plants can be used to produce electricity using CDI—as long as the emissions are present (i.e. dissolved) in the water as ions— by taking advantage of the temperature change between the charge and discharge of the electrodes.

The Namibian government has made progress towards finalising a deal to purchase the country’s sole desalination plant.1 Since September 2014, a Cabinet-appointed government negotiating team has been working with the privately-held company, Areva Resources, to purchase the plant, located in the Erongo region, 30km from the capital, Swakopmund. The Omdel water-supply system and the Kuiseb River have long supported the region’s coastal towns and businesses, however, their volumes have been diminishing over the years. In 2009, water shortages stopped the Erongo region’s uranium mining production for the first time.

The Areva plant currently supplies water exclusively to the Husab and Rössing mines; and will continue to support these mines after officials finalise its purchase. Sugnet Smith, of Areva Resources Namibia, has reported that the company is not able to reveal the plant’s purchase price prior to the conclusion of negotiations. Assuming the sale concludes smoothly, the Namibia Water Corporation (NamWater), owned by the government’s Ministry of Agriculture, will soon assume responsibility for distributing at least 11 million cubic metres of water annually; however, the plant is capable of producing 20 million cubic metres.3
