FORGE – first injection test successfully completed but no pressure equilibrium achieved

August 30, 2024

A couple of months ago, the FORGE project in Utah, USA, reported a successful stimulation and circulation test at their flagship Enhanced Geothermal Systems project. “These tests in stimulated hot…

Removing barriers to geothermal project development

Henk Kombrink

August 19, 2024

Trying to work with the current myriads of non-standardised terms, definitions, and well design types for geothermal projects is challenging. Interest in the sector is growing rapidly, but its technical…

How the winner of a technology competition made room for the losers to take over the market

Henk Kombrink

July 30, 2024

Sweden comes third in the list of countries using geothermal energy. But it is not deep geothermal energy, it is shallow geothermal – mostly sourced through closed loop systems of…

Shallow geothermal in Canada – A deep penetration in the geo-energy market

Henk Kombrink

July 16, 2024

This is the last out of three articles in the shallow geothermal series. In previous articles, we discussed shallow geothermal drilling technology, the market, and the role of the subsurface…

Shallow geothermal in Australia – from “cold” Melbourne to “hot” Sydney

Henk Kombrink

July 11, 2024

This is the second out of three articles in shallow geothermal series. In the first one, we focused our attention on Sweden, where 100% of geo-energy is produced by shallow…

Shallow geothermal in Sweden – A deep penetration in the geo-energy market

Henk Kombrink

July 5, 2024

The top three countries in terms of geothermal energy production are China, the US and Sweden. In total, these countries produced around 200 TWh in 2020. Of that figure, ground-source…

The first high-temperature aquifer thermal energy storage project in Europe

Henk Kombrink

June 27, 2024

“We have a unique geothermal energy solution here”, says geologist Eva van der Voet from Ennatuurlijk Aardwarmte in Middenmeer, the Netherlands. “The complex of greenhouses we deliver energy to is…

Why Taiwan is looking at geothermal energy with a lot of interest

Henk Kombrink

June 18, 2024

“Taiwan’s geothermal heat gradient, ranging from 48 to 60 degrees per kilometre, is a clear testament to the island’s volcanic origin. This natural advantage has sparked significant interest in geothermal…

Brushing up on your geothermal vocabulary

Henk Kombrink

May 29, 2024

It must have been a major exercise to write the paper that was published recently by authors Maryam Khodayar and Sveinbjörn Björnsson in the Open Journal of Geology. I know…

Shallow geothermal drilling is not without risk

Ronny Setså

May 2, 2024

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

Kim Gunn Maver - Green Therma

April 24, 2024

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

Henk Kombrink

April 22, 2024

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…
