SPOTLIGHT ON THE NETHERLANDS WHAT IS BLUE ENERGY?
Official opening of the Blue Energy Pilot-plant
Blue Energy is energy generated from difference in salinity between two solutions. Those solutions could be river water and sea water, for example at the point where rivers naturally empty into the sea, or sea water and brine, commonly found in industrial processes
The method can also be applied for energy reduction in desalination processes and in energy storage (in the salinity gradient).
REVERSE ELECTRODIALYSIS Reverse Electrodialysis (RED) makes use of two types of membranes; one allows only positive ions to pass and the other allows only negative ions to pass. Electricity can be generated by arranging these two types of membranes in a RED stack. REDstack is the world leader in developing RED technology, with the mission of bringing industrial-scale RED to the market.
UNIQUE PILOT-PLANT
A worldwide unique pilot-plant is located on the Afsluitdijk, a closure dam connecting the provinces of

North-Holland and Friesland, and uses water from the WaddenSea and IJssel-Lake with a total operating capacity of 50kW. This research plant was officially opened by the Dutch King Willem-Alexander. Blue Energy is under research, generated and supplied to the grid.
Because the pilot-plant is successful, the next step in the RED research programme is to upscale to a demonstration-pilot installation, in Katwijk, The Netherlands. This is conducted through the combined effort of the three project partners, Fujifilm Manufacturing Europe, Wetsus and REDstack
export product for the Netherlands. Worldwide, a potential of 2.6TW, (20% of current energy consumption) is described by Post (2007).
Blue Energy is sustainable energy without producing CO2 and without smoke-stacks. Blue Energy is independent of the weather – rain or shine, with or without wind – meaning the potential of Blue Energy is predictable, requires no back-up capacity and plays a role in the sustainable energy-mix. Real sustainability in action!
