Shallow geothermal drilling is not without risk
It is not every day that geological expertise is brought to the Supreme Court. Late last year, Norway’s highest court dealt with a claim for compensation for subsidence damage to…

A new closed-loop horizontal geothermal well solution
In Europe, deep geothermal heat production for district heating and to a lesser extent district cooling is mainly based on the conventional doublet geothermal well solution. Examples are the wells…
The deepest closed-loop borehole drilled in the UK
This is not the first time I write this, but I keep on saying it. If there is any sector in the geothermal drilling space that is active in the…
Geothermal potential of Ukraine
Ukraine has several geothermal sites and resources, especially in the Transcarpathia region and in the southern part of the country. However, the development of geothermal resources has not been extensively…
A puncture in a geothermal seal
More than fifteen years ago, Delft University of Technology (TU Delft) was one of the first institutions in the Netherlands to come up with the idea to warm their premises…
Shallow geothermal energy production may soon be more important than deep geothermal energy production in the Netherlands
It is a development that is not often talked about or highlighted in the media, but data on subsurface energy production using water as a carrier clearly shows how important…
How to explain the low energy output of one of the UK’s flagship geothermal projects?
In September last year, the UK Government announced a list of renewable energy projects that qualify for a minimum price guarantee for the energy delivered to the grid. Geothermal projects…
Monitoring a geothermal motor
Following the drilling of successful exploration wells into the Kenyan Rift Valley in the 1970’s, the flagship Olkaria geothermal field has seen a steady development to a capacity of around…
Shallow geothermal energy is also thriving in the Munich area
The Munich area in the south of Germany is situated in a genuine hot spot when it comes to geothermal energy production. Karstified Upper Jurassic carbonates have already formed an…
After four years of production, what is the verdict?
Whilst drilling of Eavor’s landmark geothermal closed-loop drilling project in southern Germany has reached the deepest point this week, the company also released a report summarising the past four years…
Geothermal resources show their limits
Development of geothermal capacity in Turkey has seen a rapid increase over the past decades but has recently slowed down.
Heating a block of houses rather than a single one
Closed loop geothermal systems, with a heat pump superimposed, form a new and promising way of domestic heating systems. Hundreds of small rigs are actively drilling these loops across many…
