Batteries are dirty. Geothermal power can help.

Scientific Concepts and Nature Phenomena Presented

• Electric Vehicles (EVs) and CO2 Emissions
  • EVs produce zero emissions during use, potentially eliminating about 18% of global CO2 emissions if all road vehicles were electric.
  • EVs are powered by rechargeable Lithium-ion Batteries, which require metals like Nickel.
• Environmental Impact of Nickel Mining and Processing
  • Nickel mining and smelting cause environmental damage including water contamination, deforestation, and air pollution.
  • Smelting Nickel requires high heat, currently mostly generated by coal-fired power plants, which emit greenhouse gases and pollutants.
  • Communities near Nickel processing plants, such as in Indonesia, suffer from respiratory illnesses due to fine particulate pollution.
• Indonesia’s Role in Nickel Production and Clean Energy Potential
  • Indonesia holds the world’s largest proven Nickel reserves and hosts many Nickel processing plants.
  • The demand for Nickel, especially for EV batteries, is rapidly increasing.
  • Despite heavy reliance on coal power for Nickel smelting, Indonesia has vast Geothermal Energy potential.
• Geothermal Energy
  • Geothermal Energy is generated by heat from magma beneath the Earth’s surface, especially in volcanic regions like Indonesia (located on the Pacific Ring of Fire).
  • Hot underground water or steam is extracted by drilling wells, used to vaporize a secondary fluid that drives turbines to generate electricity.
  • The water is recycled back underground, making geothermal a continuous, renewable, and carbon-free energy source.
  • Geothermal Energy does not depend on weather conditions, unlike solar or wind power.
  • Indonesia is the world’s second-largest Geothermal Energy producer, with about 20 active plants and many more sites under exploration.
• Challenges of Geothermal Energy Development
  • High upfront costs, long development timelines, and risks associated with drilling and resource assessment.
  • Difficulty in predicting resource size, temperature, and economic viability before drilling.
  • Potential environmental and social concerns, including:
    • Preservation of natural parklands.
    • Risk of induced seismicity (usually low-level but a concern for communities).
    • Need for environmentally, socially, and economically sustainable development.
• Economic and Social Context
  • Significant foreign investment (e.g., $30 billion from Chinese Companies) is flowing into Nickel plants powered by coal in Indonesia.
  • Transitioning to Geothermal Energy could reduce pollution and health risks for local communities like Asvina’s.
  • The importance of ensuring that the green energy transition is also socially fair, protecting marginalized communities from disproportionate harm.
• Broader Potential for Geothermal Energy
  • Many regions worldwide (highlighted in geothermal resource maps) have potential for Geothermal Energy that could help decarbonize EV battery production and other industries.
  • Exploration and technology improvements may reduce costs and risks over time.

Methodology for Harnessing Geothermal Energy

• Identify potential geothermal hotspots using geological and geothermal mapping.
• Drill wells to access underground hot water or steam.
• Use the extracted heat to vaporize a secondary fluid in a power plant.
• Drive turbines with the vapor to generate electricity.
• Reinject cooled water back underground to maintain the resource.
• Monitor and manage environmental and social impacts, including seismic activity and land preservation.
