Deep heat under Singapore could power the country 60 times over

Beneath one of the most built-up cities on Earth, survey teams have found a furnace. A two-year geophysical survey — carried out without drilling, by listening to the ground — has found high-temperature geothermal heat several kilometres under Singapore, hot enough to generate electricity, with an initial estimate of technical potential above 60 times the country's annual electricity use of about 60 terawatt-hours. The survey was run by Chevron, Metatek Group and Surbana Jurong, and Singapore's Energy Market Authority has now appointed Surbana Jurong and GLJ Ltd to run a deeper feasibility study, starting at the end of 2026, into safety, practicality and cost. Shallower, cooler heat could serve factories sooner, driving industrial heating and cooling through heat pumps. For an island that imports almost all its energy, the ground itself may turn out to be the largest power station it owns.
