‘Blue energy’ is a relatively new but promising sustainable energy source. Piotr Długołęcki from the University of Twente and Wetsus improved the most used method in The Netherlands to generate blue energy. Due to this a three to four times higher energy output can be obtained.
When salt dissolves in water it will fall apart in loaded parts: positive and negative ions. Saltwater has more loaded parts then freshwater to generate electricity. This is done with special membranes that allow either positive or negative parts through. The resulting charge is converted over the membranes into electricity.
Piotr Długołęcki aimed specifically for the transport of ions to optimalize the amount of energy. Because of his improvements the energy profits will be much higher. Długołęcki obtained his doctorate for this research on November 18th, 2009.
