AERIAL VIEWS BALTIC LAGOONS 2021
Aerial photographs of ash-storage lagoons of the largest oil shale-fuelled power plants in the world:
The Narva Power Plants, located in eastern Estonia, directly at the boarder to Russia.
As I am visiting Estonia once in a while (my wife is Estonian), I have had in mind to photograph this particular location for years, but it was difficult to get permission for, because it is so close to the NATO external boarder.
The oil shale burnt at Narva plants produces roughly 46% ash, so the stations produce about 4.5 million tons of ash per year. The ash-disposal system involves washing it away with water, and the dirty water is stored in ash-storage lagoons which appear bright blue seen from above.
The ash is highly alkaline, since the non-combustible portion of the oil shale is essentially limestone (Source Wikipedia).
