Following an influx of funding in the sector in recent years, there have been significant advances in geothermal energy. More countries are backing the clean energy source in a bid to diversify their energy mix and shift away from a reliance on fossil fuels towards green alternatives. In addition to government backing for geothermal projects, many private companies, including several technology giants, are investing in the clean energy source to help meet the growing electricity demand due to the commercial rollout of advanced technologies.
People have been tapping into geothermal energy worldwide from natural heat sources, such as hot springs, for centuries. However, over the last half a century, energy companies have been increasingly looking to source geothermal energy at less conventional locations. This involves the drilling of a borehole up to several kilometres deep, where the rocks are around 200°C, and…
