Scientists at Sevastopol State University Propose to Desalinate Sea Water with Wind Energy


The shortage of fresh water in Crimea can be compensated for by building a network of sea-based desalination stations on the Crimean shelf on the basis of wind power plants.This conclusion was made by scientists in the ‘Department of Renewable Energy Sources and Electrical Systems and Networks’ at the Institute of Nuclear Energy and Industry of Sevastopol State University during work on the internal grant.

“The North-Crimean Canal provided up to 85% of water consumption on the peninsula (approximately 1.5 million cubic meters per year). After the cessation of water supply from Ukraine, an emergency situation was avoided due to the transfer of a part of the river flow to the northern slopes of the mountains and the intensification of drilling and exploitation of groundwater.

However, as our analysis showed, these resources are not enough for industry and irrigation, ”says Victor Cheboksarov, Associate Professor in the ‘Department of Renewable Energy Sources and Electrical Systems and Networks’According to scientists, through the desalination of sea water it will be possible to replenish about 20% of the volume of water previously received from Ukraine.

The difficulty lies in the lack of energy capacity on the peninsula as desalination is a very energy-intensive process.“It takes about 2 gigawatts of power. This is four times the capacity of two new power plants built in the Crimea. Fortunately, there are renewable energy sources. We propose to create a network of marine desalination stations on the basis of innovative wind power plants. They will be located at platforms installed on the shelf off the Crimean coast, ”said Cheboksarov.According to him, fresh water will be supplied to the land via pipes, and brines formed during its production will be dumped to a depth of more than a hundred meters. With funding, scientists at Sevastopol State University could create a prototype of such an installation in 2 years.
