Deep-level geothermal energy as a sustainable energy source
DMT issues invitation to an experts’ roundtable
23.04.2012 + + + + As the transition away from fossil fuels goes forward, the use of geothermal potentials has become a focus of public discussion. New directives by the Federal Government in Germany target a modern, climate-friendly energy supply boasting at least a 30 percent share of renewable energies by 2020. To achieve this goal, deep geothermal systems are being promoted by way of a market initiative program. But in what cases are deep geothermal systems worthwhile, how can one estimate the potentials, what is the state of the art, and which projects are currently being pursued?
DMT GmbH & Co. KG has been active in this field for many years. DMT is an independent engineering and consulting company, active around the world, with a major focus on natural resources exploration. At the end of October 2011 the company was able to successfully conclude its 75th exploration campaign involving with deep geothermal resources. Covering an area of about 120 square kilometers near the German town of Gross-Gerau, subterranean structures down to a depth of 4,000 meters were explored with a tremendous degree of technical
effort.
DMT’s Exploration & Geosurvey Division carried out that work and is also the initiator of the Expert Talk on Deep Geothermal Energy, to take place in Essen on June 14, 2012. This event is intended to serve as a platform for exchanging information and experience and aims to maintain contacts among colleagues and everyone involved in geothermal research and project realisation.
Among those addressing the assembly are Prof. Rolf Bracke, Directory of the International Geothermal Center (GZB); Dr. Jörg Baumgärtner, CEO at BESTEC GmbH; Dr. Rüdiger Thomas, R&D Coordinator Geothermal Energy of the Leibniz Institute for Applied Geophysics (LIAG); Dr. Markus Wiendieck, CEO at Erdwärme Oberland GmbH; Dr. Dirk Orlowsky, Exploration & Engineering Geophysics Department Manager at DMT; as well as Prof. Horst Rüter, Vice-President of the German Geothermal Association (GtV).
The expert talk takes place under the patronage of the International Geothermal Center (GZB), the German Geothermal Association (GtV), the German Geophysical Association and the EnergieAgentur.NRW state government office. The forum also enjoys the support of the Cologne HarbourDom Consulting GmbH.
The assembly is to take place in the company cafeteria at DMT GmbH & Co. KG, Am Technologiepark 1, in Essen.

Background: Energy from the earth’s interior
Geothermal energy arises – in almost equal parts – from the time of the Earth’s creation and from radioactive decay processes at the center of the Earth, still going on today. The temperatures at the Earth’s core are estimated to be between 4,800 and 7,700 degrees Celsius. That means that 99 percent of our planet is hotter than 1,000°C. About 90 percent of the remaining 1 percent exhibits a temperature exceeding 100°C. Almost everywhere on the planet, temperatures of about 35°C to 40°C will be registered at a depth of one kilometer. In areas that show volcanic activity, either now or in the past, far higher temperatures may be found because of geothermal anomalies.
The most promising sources of geothermal energy in Germany are found in the Northern German Sedimentary Basin, in the foothills of the Alps in southern Germany, and beneath the Upper Rhine Rift. The first geothermal power plant in Germany went into operation in 2004 at the town Neustadt-Glewe (in the state of Mecklenburg-Vorpommern and in the Northern German Sedimentary Basin). A geothermal heating plant was commissioned there in 1994.

About Exploration & Geosurvey
Using methods and techniques drawn from the fields of geology and hydrogeology, geophysics, geodetics and geotechnology, the Exploration & Geosurvey Division supplies the data needed to achieve planning reliability for the extraction of natural resources (oil and gas, coal, salt, deep geothermal energy and others), for relieving the environment (carbon capture and sequestration, reducing CO2 emissions etc.) and for special-purpose civil engineering. Our work, concentrated in a single company and reaching all around the world, begins with planning, includes surveying and interpretation and extends to modeling and the final evaluation. And to ensure the very best results we also develop, operate and market our own geosurveying systems.
