Renewable Energy Source Driven Seawater Desalination

Coupling Inland Solar Electricity & Coastal Desalination Technology
(Excerpt) "Renewable energy sources (RES) for powering desalination processes is a very promising option...Renewable energy driven desalination systems have been extensively discussed as an innovative approach to desalinate water economically and in an environmentally friendly manner...Desalination systems can utilize...the available RES potential. The energy produced is consumed for potable water production which can be stored economically for a large period of time before consumption...

RES & desalination coupling schemes that do not require the RES unit and the desalination unit to be located in the same physical area are of special interest."

Adequate & Reliable Multi-Source Community Water Supply Systems
The inland Topaz Solar Farm utility-scale solar electrical plant, and others like it that are located on the existing electrical grid, would seem a likely RES that could be coupled through existing electrical power transmission lines to environmentally friendly community-scale desalination systems efficiently located near the coast. The resultant potable water could potentially be produced, stored for later pumping, or immediately moved through pipelines -- depending on the RES electrical power available from the inland solar plants.

Coastal desalinated water sources could be balancing components in adequate and reliable multi-source community water supply systems. These drinking water systems might be less susceptible to extended rainwater drought conditions. Or maybe "State of Emergency" water drought conditions. Or other disasters...

(Excerpt) "In cases where coastal cities use large amounts of freshwater, any upstream use can limit coastal supplies. But water delivered to coastal areas, such as that supplied by mobile desalination and power vessels, could additionally help both coastal and inland areas by adding extra resources."

(Excerpt) "Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use. Along with recycled wastewater, this is one of the few rainfall-independent water sources."
