in Helsinki, start of bedrock studies the reason is climate change, so coal, and later also natural gas replacement by cleaner alternatives.
Five years from the close of the Hanasaari coal power plant is replaced by the large part of wood burning, which has raised concerns of a major wood-burning consequences. Salmisaari coal burning will end in 2029 coal bans, and its substitutes are still open.
– I Believe and hope that the variety of the earth’s heat to take advantage in the solutions can be from several tens of per cent of Helsinki’s annual energy needs by the year of 2029, say helen’s investment chief Jaakko Tiittanen .
research the vehicle you are shaking the central park bike path
the bedrock of the studies done on vehicles with paws shaking the ground. Around the research area to install the sensors, which of the following how the rock responds.
the studies done on the central park jogging path, because the hardware works best in a quiet environment. Central park is not therefore to drill anything, and planned thermal plant investment the place to be.
Drill is a risk always that there under the ground was not seen.
Jaakko Tiittanen, Helen.
If the study produces a reliable estimate of the bedrock structure, the methods may also try the city area.
In the depths attract hot
the house of the heating of the earth’s heat is not in itself new. Already, many houses get their heat from the ground. For example, a layer house can warm up with a few 300 meters deep at the well of heat pumps.
But now start in the trials, the ground being probed eight miles to a depth until. There the country the temperature rises over a hundred degrees, i.e., the same readings as the district heat network running along the water.
a Couple of miles reach, by thermal wells can be heated blocks, seven miles to reach through the hole in the pair the whole neighborhood or small town.

in otaniemi in Espoo is drilled already for several years the hole pairs of 6.5 km depth. If this is the final stage of an ambitious experiment succeeds, it can be used next year to cover up to ten percent of espoo’s district heating consumption. Holes drill ava the St1 has the objective to drill the next hole to Turku.
Helen didn’t hog the deepest holes yet, at least
Helen of interest to all the heat the earth’s surface and the eight miles between.
but at the moment a functioning and economically viable are just a few hundred meters depth of the wells, where energy is taken for geothermal heat pumps.
helen’s investment manager James Tiittanen believes and hopes that beneath our feet, the temperature becomes a major energy source also in Helsinki.Petteri Right / Yle
Although Helen is monitored otaniemi therefore sites accurately, the company does not plan to now similar. The company plans to target the medium-deep for about two miles to wells and geothermal use, i.e. a few hundred meters depth in the wells. First of all, the company wants to see now launched the results of the studies.
Deep thermal wells based thermal plant of the biggest money holes is drilling.
Drill is a risk always that there under the ground was not seen. With this method, the aim is to see whether there is lithological variation or cracks that can be exploited or which may be unpredictable, where the drill might get bogged down or complicate, said the investment manager Tiittanen.
