Blue Energy

Energy produced in this way is often called Blue Energy.

RED (Reverse ElectroDialysis) is a form of sustainable energy generation. The 'fuel' consists of fresh and salt water. Rivers flow into the sea where fresh water mixes with salt water. These are the most obvious suitable locations for the application of RED. Part of the river water is led together with seawater along a membrane stack in an enclosure called REDstack. This is where the company REDstack got its name from. Salt and fresh water are mixed in a controlled manner in the stack and electrical energy is gained through this process. The resulting brackish water is returned to the sea and the electrical energy is fed into the grid and distributed from there. Translated with (free version)
