New view of deep rock fractures for geothermal energy

Scorchingly hot granite deep underground can be tapped for energy by opening up cracks in the rock. This potential resource, known as enhanced geothermal energy, requires a clear sense of changes happening in the rock over ...

Solving geothermal energy's earthquake problem

On a November afternoon in 2017, a magnitude 5.5 earthquake shook Pohang, South Korea, injuring dozens and forcing more than 1,700 of the city's residents into emergency housing. Research now shows that development of a geothermal ...

Improved risk management for geothermal systems

Enhanced geothermal systems (EGS) are considered a promising source of energy that is clean, provides a sustainable baseload for heat and electricity, and is an emerging key technology in the long-term transition to a fossil ...

Aquifers for environmentally compatible cooling and heating

In this year's record summer, everybody wishes to have a cooled home or office. But air conditioning systems consume a lot of energy and are far from being environmentally compatible. Researchers of the GeoSpeicher.bw project ...

Packing heat: New fluid makes untapped geothermal energy cleaner

More American homes could be powered by the earth's natural underground heat with a new, nontoxic and potentially recyclable liquid that is expected to use half as much water as other fluids used to tap into otherwise unreachable ...

Better data tools for a bigger geothermal future

To fully realize the potential of harnessing energy from the heat within the earth will require a far more detailed understanding of what's going on down there than scientists currently have. And beyond naturally occurring ...

Mapping the energy potential below our feet

Easy-to-access visualisation of the 'very shallow geothermal potential' (vSGP) of Europe has been made possible thanks to an EU-funded project. By harmonising pre-existing data relating to geological, hydrogeological, soil ...
