Appropriate actions for the protection of employees from contracting the SARS-CoV-2 Virus – this can be a real challenge because anyone delving into the subject quickly comes across a large number of publications and recommendations from a wide variety of sources. What can easily be lost in the process is the view of the “big picture”. What really needs to ...

The SARS-CoV-2 Occupational Safety Rule specifies the requirements for occupational safety for the period of the epidemic situation of national importance in accordance with Section 5 of the Protection against Infection Act. It has been issued by the occupational safety committees at the Federal Ministry of Labour (BMAS) in coordination with the Federal Institute for Occupational Safety and Health (BAuA), ...

The control of process systems is usually based on the measurement of process variables such as temperature, pressure, quantity or level or certain material properties. The processing of the information determined by sensors in the process control system, the display of the data in the control room or at the control stand, and the automatic or manual actuation of valves ...

The coal phase-out in Germany by 2038 constitutes a major challenge for regions and industries. Technologies, energy sources and labor markets are changing fundamentally. But there are also opportunities for local actors that are worth to be explored. Even old mines could contribute to the success of the transition of energy production. The German Parliament installed the Fraunhofer Institute for ...

Geothermal energy can play an important role in the decarbonization of the German energy system. In order to make the great potential of geothermal energy in the crystalline basement economically viable, measures are taken to enhance existing permeable structures. However, a prerequisite for the public acceptance of such Enhanced Geothermal Systems (EGS) is the minimization of possible induced seismicity. Their ...

Geothermal resources have huge future potential and could well replace much of our fossil-fuel and nuclear based heat and electricity supplies. Geothermal energy is climate neutral and is available all year round. However, it presents significant technological challenges and is highly capital intensive. This applies both to near-surface geothermics and, more especially, to deep-level geothermal operations, where deep wellbores have ...

By late 2020 a total of 77 deep geothermal wells had been drilled within the territory of Austria, representing a cumulative length of some 135 km. About two thirds of this figure, both in terms of number and cumulative length, comprised boreholes sunk in sedimentary basins, while the remainder were drilled in the Eastern Alpine units and consisted exclusively of ...

Natural gas is besides from crude oil and coal one of the most important energy resources. However, during the depletion of a reservoir, the occurrence of liquids, e. g., water, condensates, is a well known phenomenon worldwide. Depending on the gas composition and the physical boundary conditions (pressure, temperature), water and/or condensate can precipitate out of the gas stream as the ...

The aim of this article is to provide an overview of the main stations of the Innova Rig Terra Invader 418 drilling rig from Herrenknecht Vertical GmbH, Schwanau/Germany, and its positioning on the national and international geothermal market since it was launched. The main features, advantages and benefits of the drilling rig are discussed, such as, e. g., sound protection during ...

Geothermy is a raw materials production process and therefore it has a close association with mining law, unless the activity in question is strictly property related. However, even in this latter case mining regulations will take effect if the drilling extends to a depth of more than 100 m. A general operating plan is not in fact required in this ...
