Summary

The search for geothermal energy in Singapore is hotting up, as researchers from Nanyang Technological University (NTU) are set to expand their search for underground heat reservoirs across the island.

Progressing to the second phase of their study, researchers will be burying another 80 seismic sensors underground, spanning the north-east and south of Singapore.

This comes after the team’s breakthrough discovery of a highly fractured and shallow geothermal reservoir south-east of Sembawang Hot Spring Park in 2024.

That team found that heat between 30 deg C and 60 deg C can be used for water desalination and fish farming, while that above 90 deg C could be used for district cooling. Temperatures above 150 deg C are suited for electricity and hydrogen generation.
