Superhot Rock Geothermal in Spain

The document highlights that just 1% of Spain's superhot rock geothermal resource could provide 229 GW of energy capacity, potentially replacing all coal and gas used for electricity production and reducing emissions by approximately 41 megatonnes of CO2eq.

• Preliminary modelling by the Clean Air Task Force and the University of Twente indicates that Spain possesses significant superhot rock resources. Specifically, 1% of this resource could provide 229 GW of energy capacity, generating over 1,909,314 GWh of electricity, which is seven times Spain's 2021 electricity consumption.
• Utilising 1% of Spain's superhot rock geothermal potential could theoretically eliminate the use of coal and gas in electricity production, reducing carbon emissions by about 41 megatonnes of CO2eq. This would represent 32% of Spain's share of the EU's Nationally Determined Contribution (NDC) goal, although the technology is not expected to reach commercial scale by 2030.
