Power Generation Using Wind and Geothermal Hybrid: A Case Study From Dholera
India is planning to achieve around 50% of clean energy share of 500 GW renewable energy capacity by 2030. In this clean energy drive of India geothermal plays an important role. The geothermal fields of India are categorised into four classes on the basis of its tectonic framework. The present study is based on Dholera geothermal field which is a low-medium enthalpy field of India. In this paper the low enthalpy geothermal water has been used for space heating and cooling purpose and the residual of 80oC from the plant will be used for power generation using wind and geothermal hybrid. A novel hybrid technology is suggested in this paper which combines a ventilation system with a wind turbine to generate power. To obtain the desired air velocity within the column, geothermal energy will be employed as a heating element. This heated wind then will act as the source to drive the wind turbine for power generation. A prefeasibility model for this hybrid wind and geothermal technique has been proposed for electricity production which is first time in India.
