Badania wiatrów na Bałtyku

aktualności 09 maj, 2019

Jak donosi www.kierunekenergetyka.pl na wysokości latarni morskiej w Stilo, około 30 km od linii brzegowej, zainstalowano laserowe urządzenie pomiarowe, tzw. pławę z lidarem. Rejestruje ono odbite od cząsteczek powietrza wiązki laserowe, dzięki czemu jest w stanie dokonać pomiaru parametrów wiatru na różnych poziomach, do 300 metrów nad powierzchnią morza. Grupa ORLEN posiada na Bałtyku koncesję, w ramach której może zbudować morską farmę wiatrową o mocy do 1200 MW. W celu zbadania warunków środowiskowych i potencjału będą mierzone takie parametry wiatru jak prędkość, kierunek, siłę i turbulencje. Morskie farmy wiatrowe na Bałtyku mogą być bardzo perspektywicznym źródłem czystej energii.
