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 ...

First algae powered building goes up in Hamburg

(Phys.org) —A 15-unit apartment building has been constructed in the German city of Hamburg that has 129 algae filled louvered tanks hanging over the exterior of the south-east and south-west sides of the building—making ...
