Blue energy: water power

RNW archive

This article is part of the RNW archive. RNW is the former Radio Netherlands Worldwide or Wereldomroep, which was founded as the Dutch international public broadcaster in 1947. In 2011, the Dutch government decided to cut funding and shift RNW from the ministry of Education, Culture and Science to the ministry of Foreign Affairs.

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.
