Superhot Rock Geothermal in the Philippines

The document highlights that just 1% of the Philippines's superhot rock geothermal resource could provide 216 GW of energy capacity, far exceeding the country's 2021 electricity consumption of 106,110 GWh. This resource could theoretically replace all coal and gas used for electricity production, reducing emissions by approximately 75 megatonnes of CO2eq, and significantly reducing the country's 90% dependence on coal imports, primarily from Indonesia. Additionally, superhot rock geothermal is noted for its high energy density, requiring only 12 km² of land per 1 GW, which is substantially lower than solar, wind, or biomass.

• Preliminary modeling indicates that the Philippines possesses significant superhot rock resources; specifically, 1% of this resource could provide 216 GW of energy capacity and generate over 1,801,202 GWh of electricity.
• The potential energy from 1% of the Philippines's superhot rock resource is estimated to be 17 times the country's 2021 electricity consumption of 106,110 GWh.
• Superhot rock geothermal could significantly improve energy security by replacing fossil fuel imports; currently, the Philippines imports 90% of its coal, with the majority sourced from Indonesia.
• Superhot rock geothermal is highly land-efficient, requiring approximately 12 km² per 1 GW, which is significantly less than natural gas (160 km²), solar (180 km²), offshore wind (520 km²), and biomass (14,000 km²).
