| Abstract | Geothermal energy, while a promising source of clean, baseload power, faces numerous challenges across technical, economic, environmental, and regulatory domains. Technically, geothermal exploration involves complex subsurface analysis and deep drilling under extreme conditions, posing risks such as wellbore instability and equipment wear. Reservoir management also demands precise reinjection strategies to prevent pressure imbalances and induced seismicity. Economically, geothermal projects are capital-intensive with high upfront costs, exploration risks, and prolonged payback periods, complicating financing and insurance. Environmentally, geothermal development is associated with risks like induced seismicity, gas emissions (e.g., H₂S and CO₂), water resource contamination, and land degradation. Mitigating these impacts requires robust emission controls, brine management, and biodiversity protection. Regulatory challenges include complex permitting, land use disputes, and inconsistent policy incentives that deter investment. Natural hazards such as earthquakes, volcanic eruptions, floods, and droughts add further risks, particularly in geologically active regions. Case studies highlight lessons learned: the Basel project in Switzerland underscores the need for seismic risk assessments; The Geysers in the U.S. demonstrates successful reinjection practices; and Iceland showcases the value of policy support and public trust. Looking forward, the paper advocates for improved exploration techniques (e.g., machine learning, 3D modeling), advanced drilling technologies, integrated monitoring systems, and policy reforms. Engaging local communities and enhancing international collaboration are also emphasized to ensure socially responsible and resilient geothermal development. |
