The waste product in this process is brackish water. The technology of reversed electrodialysis has been confirmed in laboratory conditions. As in common technologies, the cost of the membrane was an obstacle. A new, cheap membrane, based on an electrically modified polyethylene plastic, made it fit for potential commercial use. As in a fuel cell, the cells are stacked. In the Netherlands, for example, more than 3,300 m³ fresh water runs into the sea per second on average. The energy potential is therefore 3,300 MW, based on an output of 1 MW/m3 fresh water per second. Size A module with a capacity of 250 kW has the size of a shipping container. Testing 2005 A 50 kW plant is located at a coastal test site in Harlingen, the Netherlands. The focus is on prevention of biofouling on the anode, cathode and membranes and increasing the membrane performance.

This page uses material from the Wikipedia article Blue energy About Oilgae - Oilgae - Oil & Biodiesel from Algae has a focus on biodiesel production from algae while also discussing alternative energy in general. Algae present an exciting possibility as a feedstock for biodiesel, and when you realise that oil was originally formed from algae - among others - you think "Hey! Why not oil again from algae!" To facilitate exploration of oil production from algae as well as exploration of other alternative energy avenues, Oilgae provides web links, directory, and related resources for algae-based biofuels / biodiesel along with inputs on new inventions, discoveries & breakthroughs in other alternative energy domains such as solar, wind, nuclear, hydro, geothermal, hydrogen & fuel cells, gravitational, geothemal, human-powered, ocean & wave / tidal energy.
