Singapore's geothermal potential dwarfs annual electricity needs: EMA

The Energy Market Authority (EMA) released findings from a non-invasive geophysical survey that has mapped previously unknown geothermal resources located several kilometres beneath Singapore's surface. The survey identified high-temperature geothermal zones that may be harnessed for power generation, marking a significant development in the nation's energy exploration efforts.

According to the EMA's assessment, Singapore's estimated geothermal resource potential exceeds 60 times the island's annual electricity consumption, presenting a potentially substantial energy reserve. The discovery could diversify Singapore's energy portfolio and reduce dependence on imported fuels and regasified liquefied natural gas, which currently dominates the country's power generation mix.

Geothermal energy has long been considered a clean, renewable power source with minimal environmental impact and consistent output capabilities. The identification of suitable geothermal reserves near Singapore could support the nation's climate goals and energy security objectives, though further development and feasibility studies would be required before commercial exploitation could begin.

The non-invasive nature of the geophysical survey means the assessment was conducted without drilling or disturbing underground formations, making it a preliminary but promising step toward evaluating Singapore's geothermal potential. The findings are expected to inform future energy strategy discussions as Singapore seeks sustainable alternatives to conventional fossil fuels.
