Analytical and Numerical Models for Determining Geothermal Energy Potential: A Case Study in India

The energy supply in India is based on coal, whose reserves are present in eastern and central provinces of India. The electricity distribution network cannot rely on the potential hydraulic system that is subject to sharp fluctuations due to the monsoon rains and floods. In recent years, attention has been focused on renewable energies. One of the most attractive options is the exploitation of geothermal reservoirs, especially in northern India. The priority for research of geothermal sources is the Puga valley in Ladakh district in the state of Kashmir, 1,600 km from New Delhi and at an altitude of about 4,400 m. This work presents alternative ways for determining thermal energy exploitation, looking at both analytical and numerical models. After discussing the different approaches, an example of a possible application in India is shown and results are discussed.
