The final drilling phase of energy company St1’s geothermal heat pilot project is about to begin in Otaniemi, Espoo.
The first 6.4 kilometre-deep geothermal heat well was completed last year, and the second well to a depth of 3.3 kilometres awaiting the results of water stimulation modelling. The drilling plan for the remaining part of the second well has been determined according to modelling and the actual drilling will start in September.
Once complete in 2020, the plant will be the world’s deepest geothermal heat production plant, which will produce heat completely without emissions.
