The influence of fractures on geothermal heat production in the Roer Valley Graben

This thesis looks into the possibility to produce geothermal energy in the Roer Valley Graben. The locations in this area are limited due to the low permeability of the deep Triassic layers. Fractures can enhance the heat production by increasing the effective permeability and decrease the pressure that is needed to produce the heat. However,...

MUSIC: GIS based EPM and residual heat potential

We do live in interesting times. Social, political and financial turmoil, peak oil and nuclear accidents all contribute to the realisation that perhaps things need to change in our energy system. Providing the right type of energy at the right place at the right time is of course the answer. As the potential yields of renewable energy sources...

Exergy analysis of the use of geothermal energy and carbon capture, transportation and storage in underground aquifers

At the moment global climate change is one of the most prominent environmental and energy issues of our life time. Currently CO2 levels in the atmosphere stand at 387 ppm, almost 40% higher since the start of the industrial revolution and the highest for at least the last 650,000 years. About 96% of these carbon emissions are the result of using...
