The city of Almere and energy suppliers HVC and Vattenfall will investigate in the coming years whether the ground under Almere is suitable for producing geothermal heat. The three parties signed a cooperation agreement regarding this on Monday afternoon.
Warm water is planned to be pumped up at a depth of two kilometers. That heat is used through a heat exchanger to heat buildings. The cooled water is pumped back into the ground.
In Almere previous research done to geothermal energy, says consultant Alexander Sprong. “It wasn’t clear if we could bring him to the surface as well. ” This is now being investigated further.
The deeper it is
According to HVC’s Marco van Soerland, you have to go deep into the ground if you want to use the water to heat buildings. “Every kilometer you go deeper, it’s between 30 and 35 degrees warmer. So if you’re about two to two and a half kilometers, you have about 80 degrees of water. So that’s great for heating houses. ”
Geothermal energy is very important to Almere, says Alderman Sprong: “Our heat now comes mostly power plant in Diemenwhich runs on gas. As a city, we want to move towards energy independence. We are looking for a sustainable source for this. And that includes geothermal heat.”
The research focuses on the layers of the earth above warm water. These layers of soil must be suitable for drilling through to lay the kilometers of pipes. HVC’s Van Soerland expects the search to take years. He hopes that the first test drill can take place in 2030.
