مضخة حرارية في البلطيق لتوفير %40 من طاقة هلسنكي

By Phil Bainbridge

October 24, 2022 - مشروع طاقة تبلغ قيمته 400 مليون يورو وبقدرة تصل إلى 500 ميغاواط الهدف منه توليد الحرارة للعاصمة الفنلندية سوف يستخرج المياه العميقة من قاع البحر، حتى عندما يتجمد السطح.

Seawater will be carried to the heat exchangers via a 17km tunnel being bored from the Baltic seabed - where the temperature is a constant 2˚C year round. Heat exchangers will transfer and concentrate the heat from the seawater - which is returned to the sea through a 9km tunnel - to the district heating system where it will reach around 88˚C.

Already home to the world’s largest heat pump, Helsinki is aiming to become carbon neutral by 2050, and the new pump alone is expected to provide up to 40% of the city’s heating requirements when it goes online in around 2029. The utility company Helen Ltd currently provides around 8% of Helsinki’s heating through recovering heat from waste water and the excess from data centres and other buildings.
