Large-scale geothermal energy has long been constrained to volcanic areas where heat can easily be captured and turned into electricity. Today, breakthroughs in drilling techniques are opening new horizons, offering the prospect of “geothermal anywhere”.
In this special report, EURACTIV looks at the latest developments in geothermal technology and the remaining challenges that need to be addressed before it can become a cheap and reliable source of renewable energy.
A growing number of cities in Europe are betting on geothermal to provide households with clean heating, but the little-known renewable energy source will need more attention from Brussels in order to scale up.
Geothermal power is a reliable and renewable energy source that is local by its nature and offers baseload power generation. Alongside energy efficiency measures and other renewable heat sources, like heat pumps, it could be part of the solution to Europe's energy crisis, says Sanjeev Kumar.
Geothermal energy has until now been constrained to areas with special geological conditions where the earth’s heat is close to the surface. Today, closed-loop technologies make geothermal accessible almost anywhere in the world, opening up new prospects for mass-scale deployment.
The ability of geothermal energy to provide baseload electricity and flexibility to heating and power systems will be invaluable in order to move towards a 100% renewables-based system, experts say.
The energy industry is at a moment of reckoning. As the global energy demand continues to double and triple, climate change will not wait for us to solve the green energy conundrum on our own schedule.
