EcoWorldly reports that Saltwater Power Could Supply Energy for Most Dutch Homes. A new proposal to improve a 75-year-old dike, the Afsluitdijk, in The Netherlands could make it the world’s leading site for generating saltwater power— a clean, Blue Energy source which is 30-40% more efficient than burning coal.
The breakthrough process, which is called reverse electrodialysis, captures the energy created when freshwater becomes saltier by mixing with seawater. Although scientists in the 1950s discovered that electricity could be generated this way, no one knew just how efficient the process could be until a recent study proved that a remarkable 80% of the energy could be recovered.
The sea is the Netherlands biggest enemy, with most of the country being below sea level. The sea may actually pose its benefits.
