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…
Geothermal
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…
Drilling twice as fast in basement rocks
John Gibb’s Aberdonian accent is noticeable even though he has spent many years in Houston. “I drilled many wells throughout my career”, he says, “including highly deviated development wells on…
Exploration drilling – for geothermal energy
Only a few days ago, a very interesting drilling campaign kicked off in the Netherlands, at a very prominent location close to the Ajax football stadium in Amsterdam. And while…
An order of magnitude more energy for drilling twice as deep
“What attracted me to geothermal is the fact that there are still a host of technical challenges to be addressed in order to unlock it as the ideal complement to…
The economics of geothermal pumped well power projects
Geothermal pumped well projects provide power to the grid at a contract price and terms negotiated with the power off-taker. This can vary significantly from country to country, but as…
Extended reach drilling for geothermal energy production
The energy transition is about pipe, lots of pipe. Where gas can be transported across the globe, geothermal energy, especially the low-temperature version of it that is mainly used for…
A geothermal gold rush
When it comes to producing geothermal energy, Munich is without a doubt the place to be in Germany. As the map here clearly shows, the city is dotted by wells…
Groundwater flow – a potential cost-saver for shallow geothermal loops
The energy transition is all about pipes. Where a single gas well was sufficient to deliver energy to power an entire city until recently, closed-loop geothermal boreholes are now increasingly…
Understanding geothermal energy
The energy contained in a geothermal fluid is defined by its enthalpy, generally given in kilojoules per kilogram (kJ/kg). For a liquid, the enthalpy is primarily determined by its temperature.…
