On 13th of September 2020 the first in the world hybrid system for lake purification: floating PV and aeration system was installed on lake Ak-Gel. Lake Ak-Gel is located in the center of Makhachkala (Dagestan Republic, Russia) and it faces many serious ecological problems:
* Oxygen concentration is 3 times less than normal;
* Active algae growth;
* Water evaporation (area was reduced twice during the last 20 years).
Engineers from HelioRec, a Skolkovo innovation center resident, and Eco-Energy (project developers) invented the unique solution to solve these problems. Floating power plant with the total area of 150 m2 that consist of:
* 24 floaters with 295W photovoltaic modules (Solar Systems);
* 36 footpaths;
* 4 batteries;
* 4 aerators which can help to bring needed amount of oxygen to revive the lake within 1 year.
In the process of developing the first project of its kind in the world, engineers were required to apply fundamentally new solutions: aerators are powered by an autonomous solar generation with a 7 kW capacity based on a floating system, and “smart control technology” allows to control the power plant from a mobile phone.
The system could survive the first storm (19.09.2020) with wind speed more than 30 m/s (link).
Based on the results of the first installation, HelioRec and Eco-Energy will decide about increasing size of the power plant and further project development.
