Superhot Rock Geothermal in Indonesia

The document highlights that just 1% of Indonesia's superhot rock geothermal resource could provide 1,982 GW of energy capacity, far exceeding the country's projected 2050 electricity demand of 936,986 GWh. It argues that this technology could replace all coal and gas in electricity production, reducing emissions by approximately 240 megatonnes of CO2eq, while requiring significantly less land than solar, wind, or biomass. The report suggests Indonesia can leverage its existing conventional geothermal expertise to transition to this emerging technology, which could also foster socio-economic development and improve air quality.

• Preliminary modeling indicates that Indonesia possesses vast superhot rock resources; specifically, 1% of this resource could provide 1,982 GW of energy capacity and generate over 16,492,935 GWh of electricity.
• The energy potential from just 1% of Indonesia's superhot rock resources is sufficient to meet the country's projected 2050 electricity demand of 936,986 GWh, leaving over 15,555,949 GWh for other uses like hydrogen production, desalination, or exports.
• Superhot rock geothermal is highly energy-dense with a low land footprint, requiring approximately 12 km² per 1 GW of production, which is significantly lower than natural gas (160 km²), solar (180 km²), offshore wind (520 km²), and biomass (14,000 km²).
