The process, called osmotic power, is a harvesting the energy that appears when salt water and fresh water meet through an osmotic filter. For the moment, the project is small-scale but could prove the great potential of osmotic energy.
Saltworks Technologies reported that they can produce 1 cubic meter of fresh water using just 1kWh compared to 3.7kWh per cubic meter achievable using reverse osmosis.
As the world’s potable water resources thin each year, scientists strive to decypher ways to use the immense amounts of water that abound the oceans and seas, and to make them drinkable. All that desalination process consumes energy resources, and that makes water more expensive to produce and drink in some parts of the world.
