Offshore Geothermal Energy Extraction: A Renewable Frontier in Oceanic Crust Utilization

Explore the potential of offshore geothermal energy with insights on the world energy scenario and finite element modeling for load analysis. Geothermal energy is a renewable power source that harnesses the heat generated by the Earth, with specific focus on utilizing this energy from oceanic crust areas like mid-ocean ridges. Learn about the thermal loading considerations, heat transfer concepts, and the structural responses involved in extracting energy from offshore geothermal sources. Presented at TFAWS 2016 by Ms. Arundhuti Banerjee from the Indian Institute of Technology (IIT) Delhi.

  4. Offshore-Geothermal Energy Geothermal energy -Renewable and sustainable power source that comes from the heat generated by the earth -Harnessed in areas of volcanic activity -Electricity generating potential of geothermal energy vary from 35 to 2,000 GW Ring of fire zone Geothermal heat extraction process

  5. Offshore-Geothermal Energy Geothermal gradient is the rate of increasing temperature with respect to increasing depth is about 25 °C per km of depth in continental crust and mean heat flow is 65 MW/m2 whereas 35 °C per km of depth in oceanic crust with 101 MW/m2 of heat flow Mid-ocean ridges More concentrated in areas where thermal energy is transported toward the crust bymid-ocean ridges.
