Recent research conducted by Jie Li from the College of Environmental Science and Engineering at Guilin University of Technology has shed light on the geothermal potential of the Midu Basin in Yunnan Province, China. Published in the journal Energies, this study employs seismic imaging technology to evaluate medium-deep geothermal resources, a critical step in harnessing geothermal energy for clean power generation.
Geothermal energy is increasingly recognized for its role in reducing carbon emissions and providing a stable, renewable energy source. The Midu geothermal field, located in a region known for its high-temperature geothermal resources, has significant potential but has historically underperformed in terms of utilization, with less than 0.5% of its reserves currently being tapped. This is largely due to the considerable depth of the geothermal resources, which poses exploration challenges.
Li’s study utilized natural seismic data to perform a tomographic analysis of the geothermal system in the Midu Basin. The findings indicate that the basin consists of two primary structural layers: a thrust basement from the Mesozoic and Paleozoic eras and a sedimentary layer from the Cenozoic era. The research identifies a low-velocity anomaly in the central basin, indicating a loose sedimentary layer, while high-velocity anomalies at the edges suggest the presence of more stable geological formations.
One of the key insights from this research is the identification of the MiDu Fault as a significant control point for geothermal storage. “The MiDu Fault exhibits higher thermal conductivity than the Yinjie Fault, making it a crucial conduit for water,” Li noted. This suggests that the western side of the basin is particularly promising for developing medium-high temperature geothermal resources, which can be used for power generation.
The implications for the energy sector are substantial. As countries strive to transition to cleaner energy sources, harnessing geothermal energy can provide a reliable and environmentally friendly alternative. The study emphasizes that geothermal power generation is zero-emission and pollution-free, potentially offering a continuous power supply with over 8,000 operating hours per year. This reliability far exceeds that of solar or wind energy, especially in regions like southwestern China.
Furthermore, the research highlights opportunities for commercial ventures in heating and wellness applications, particularly around the Yinjie Fault area, which is more suited for such uses. This opens avenues for businesses to invest in geothermal heating systems, spas, and other wellness facilities that leverage the region’s geothermal resources.
Overall, the findings from Jie Li’s study not only enhance our understanding of the geothermal landscape in the Midu Basin but also signal a promising opportunity for the energy sector to invest in sustainable energy solutions. The utilization of advanced seismic imaging techniques marks a significant step toward unlocking the geothermal potential of this region, paving the way for cleaner energy initiatives in China and beyond.
