Sharper Focus on Drilling Technology will Open Door to Geothermal Revolution

Traditional drilling techniques have hamstrung the vast potential of deep geothermal—too long on site, too many risks and too high of a market barrier—which is why, particularly given the potential of enhanced geothermal systems, it is time for the sector to take a fresh approach to its core technology.

The global shift toward the collective net-zero future is accelerating at pace with renewable energy and other low-carbon initiatives leading the charge and with society and industry rightly pursuing every means available to minimize emissions and address the climate emergency.

Geothermal energy has much to contribute; by tapping into the heat stored beneath the earth's surface—where temperatures at the core are measured in thousands of degrees—it is possible to radically reshape the energy future.

In part that is because of the scale of the resource. Consultancy Wood Mackenzie reported last year that geothermal could contribute in excess of 1,000 GW by 2050, more capacity than either nuclear or hydro currently supply.

Unlike renewables pace-setters wind and solar, which by their nature are intermittent, geothermal is regular and dependable. This makes the energy ideal for providing the baseload electricity required to complement existing decarbonization efforts.

Cost, however, has been an issue. Traditional drilling techniques in particular have hamstrung the vast potential of deep geothermal: too long on site, too many risks and too high of a market barrier.

That is why, particularly given the potential of enhanced geothermal systems and advanced geothermal systems, HydroVolve, a specialist energy engineering company, believes it is time for the sector to take a fresh approach to its core technology.
