Correction to: Cyclic soft stimulation (CSS): a new fluid injection protocol and traffic light system to mitigate seismic risks of hydraulic stimulation treatments

Geothermal Energy, 2019
After publication of the article [1], it has been brought to our attention that there is an error in Figure 7. Instead of the “2” in the first row of the green and yellow stages of the traffic light system it should be a “3”.

Cyclic soft stimulation (CSS): a new fluid injection protocol and traffic light system to mitigate seismic risks of hydraulic stimulation treatments

Geothermal Energy, 2018
Hydraulic stimulation treatments are standard techniques to access geologic resources which cannot economically be exploited with conventional methods. Fluid injection into unproductive formations may increase their permeability by forming new fractures ...

Repurposing idle wells in the North German Basin as deep borehole heat exchangers

Geothermal Energy
This study investigates the feasibility to repurpose wells from gas production for geothermal closed-loop application in the North German Basin (NGB). The objective for this research topic is to extend the value-added chain of idle wells by re-completion

Solar thermal vs. PV with a heat pump: A comparison of different charging technologies for seasonal storage systems in district heating networks

Energy Conversion and Management: X
The majority of district heating networks (DHNs) in Germany and other European countries are still supplied by fossil fuels. While several possible technical solutions exist to decarbonize DHNs, the problem is the availability of solar energy – thermal ...

Three-dimensional geologic mapping to assess geothermal potential: examples from Nevada and Oregon

Geothermal Energy, 2019
Geologic structure plays an important role in controlling fluid flow in geothermal systems. In particular, very complex structural settings, consisting of many closely spaced and intersecting faults, host many geothermal systems.
