Blue energy: water power
Published on:Monday, April 16, 2012 - 15:55
Blue Energy, the power generated by the difference between fresh and salty water molecules, could provide for the entire world’s energy needs. That’s right, 100%.
But 'could' is the operative word; researchers at the Wetsus institute in Leeuwarden say they would be quite pleased if they could produce 10%. They’re currently carrying out large-scale tests near the Afsluitdijk in the north of the Netherlands.
The Afsluitdijk, a major causeway separating the salty Wadden Sea and the freshwater IJsselmeer lake, is an ideal spot to experiment with this blue energy, which results from creating a tension between fresh and salty water.
Extensive testing in laboratories has proven that Blue Energy works. And, of course, it's very sustainable - the resources are virtually inexhaustible and production doesn’t require much space. Researchers are now ready to carry out a large-scale test on the Afsluitdijk. Wetsus has already secured the necessary permits to build the first experimental power station.
