In pursuit of achieving net-zero emissions by 2050, Singapore is exploring the immense potential of geothermal energy as a promising renewable solution. Despite limited knowledge about its geothermal resources, a groundbreaking project led by renowned scientists, Professors Rainer and Wei from NTU, aims to bridge this gap by conducting an extensive investigation.

The project’s focal point is Sembawang, where advanced gravimeter sensors are utilized to measure gravity anomalies caused by subsurface fluids. Professor Rainer and his team have developed a cutting-edge quantum gravimeter capable of precise absolute gravity measurements. Simultaneously, Professor Wei and his team have deployed relative gravimeter stations at the Sembawang drilling site to obtain relative gravity values. By calibrating the relative gravimeter readings with absolute gravimeter data, the teams can generate a detailed map of absolute gravity anomalies across the test site.

Additionally, seismic sensors are being deployed by Professor Wei and his team to detect potential seismic signals originating from active faults beneath the subsurface. The integration of gravity and seismic surveys within this project promises crucial insights into subsurface geothermal energy, significantly contributing to future geothermal exploration in Singapore. Leveraging these innovative approaches, the project aims to pave the way for a sustainable and greener future, aligning with Singapore’s net-zero emissions target by 2050.
