Terrestrial heat without earthquakes

Very hot water from the depth is to supply warmth and river. photo: geox (openPR) - in new castle one would like to start still 2007 with a Geothermie project

They whirled the entire industry in disorder and shook the confidence into a still recent technology: the earthquakes in Basel - released of the there Geothermie project. In the Markgräflerland the responsible persons might have it now still more with difficulty to find backers for 20 million a euro-project. The Stoltenberg energy GmbH with seat in Schleswig-Holstein plans a Geothermie power station in new castle since 2004. It does not want to be thrown with Basel into a pot.

In Basel probably the circumstance was for quake responsible that the drills penetrated into a depth of 5 of,000 meters there, into firm rock. Into this depth inside with high pressure water was pressed, so that it can heat up there. Hot Dry skirt procedure is called that. Into new castle the drills are to advance only into a depth of 2 of,800 meters. There a pouring in such a way specified is to be appropriate, an underground lake with 140 degrees for hot water.

The largest difference to Basel: Here no water is pumped to the depth. It is only up-carried, which natural-proves in loose rock is already present. Hydrothermales procedure is called that. New castle shows like many places in the upper pure ditch geothermal anomalies so mentioned. That is, it is here in 2,800 meters of depth already as hot as elsewhere only in 4,000 meters. Therefore the upper Rhine ditch is a so favorable terrain for Geothermie.

Force heat coupling will be used into new castle. From the energy in the depth both river and warmth are won. 2.9 megawatts river and 9.6 megawatts warmth are calculated. The river can be fed into the public net. With the warmth a development area in new castle, which is in planning, could be supplied or the close of the drill location of convenient industrial companies.

That particularly high temperatures under new castle prevail, one already knows since the 70's-years, when in the area sample drillings were made. „It gave at that time however no EEG “, explains Robert Doelling, with Stoltenberg for the new castle project responsible person project developer, why one left the Energiepotenzial 30 years in the earth schlummern. For geothermally produced river the EEG, the law, 15 cent per kilowatt-hour feeding remuneration plans renewable energies. „Doelling really is because of the lower limit “, says. For solar electricity more than 40 cent is paid. Doelling: „If we so much would get, would be already full the upper Rhine ditch with Geothermie power stations. “15 cent is not much, but during one period of 20 years a reliable size.

„That is, as if a mosquito stings an elephant. Those can suck that also not empty “, explains Doelling. Is to be called, the quantity of underground hot water rich out to hold the power station far beyond 20 years in enterprise. This concerns a closed cycle. The water pumped up is carried back, after it delivers its energy has, again into the depth, where it can heat up on the new.

The disadvantage of wind, water and solar electricity: The quantities vary, depending upon wind conditions, water levels and duration of sunshine. Geothermie is freely of such fluctuations, it is basic loadable like charring and atomic power plants, but in contrast to those CO2-frei.

„The Hot Dry skirt procedure still is in the development phase, therefore we make it not “, explain Doelling. But also the Neuenburger project has its Tücken. The recently created project company must find 20 million euro. Risk capital - with the drilling nobody knows by hundred percent whether the prognoses supporting by the sample drillings and geological appraisals prove to be true. There is the risk not to become fündig or find smaller occurrences. 20 years must the hot wet permanently from the depth gush. Whether that functions in practice actually so smoothly, is not able to guarantee also Doelling. Or whether not also here tectonic disturbances - if it also no earthquakes release - which disturbs and impairs river upward.

Bath new facts and energy service are in relation to the project „unlocked “, so new castle mayors Joachim shoemaker. Bath new facts the warmth could decrease, to energy service the river. Obligatory promises however gave both enterprises still none.

New castle reserves already for years to the A5 an urban property for the power station. And it supports Stoltenberg also with authority courses and with the search for investors. Shoemaker calls it one „alternative to Fessenheim “, in addition, a project, which cannot be financed „from the region alone out “.

Stoltenberg energy hopes that to center of the yearly the financing stands and can still for 2007 be begun. A perspective could be the interrain promotion pot of the European union. Shoemaker originally thought of a trinational Geothermie group: New castle in Germany, Soultz sous Forets (Nordelsass) in France and Basel in Switzerland. Basel probably is after the earthquakes raus. Then it becomes binational stop.
