Geothermal Energy Poised to Power Singapore’s Future
Singapore is exploring geothermal energy as a crucial component of its strategy to achieve net-zero emissions by 2050, potentially offering significant cost savings and environmental benefits.
Cost-Effective Energy
Simulations conducted by researchers indicate that geothermal systems could substantially reduce electricity generation expenses. The models showed a potential decrease of at least 38% in electricity generation costs and a 39% drop in the costs of chilled water production when applied to Singapore’s district cooling system.
Beyond cost, geothermal energy could slash greenhouse gas emissions by a minimum of 90%, according to the research team’s findings.
Mr. Chidire emphasized Singapore’s proactive approach to diversifying its energy sources, noting that geothermal energy can play a vital role, enhancing both energy security and environmental responsibility. He added, “Singapore is prudent enough to know that they want to diversify their electricity mix in future. They do not want to go only with 100 per cent imports, or go only with hydrogen, or only solar,”
recognizing the limitations of relying solely on solar power.
Geophysical Survey Underway
Encouraged by the promising data, the Energy Market Authority (EMA) has initiated a geophysical survey to gain a deeper understanding of Singapore’s subsurface and identify potential geothermal hotspots, according to Dr. Poh. The survey results are anticipated by the end of 2026.
Next Steps: Pilot Program
Professor Alessandro Ramognoli, who is leading the research collaboration, stated that the existing data is “quite compelling.”
The team is actively seeking collaborations with both the public and private sectors to launch a pilot demonstration project to study the practical aspects of deploying geothermal energy. Professor Ramognoli added, “From our side, what we are working on is to see whether we can bring together the public sector, together with the private sector, to go for a pilot demonstration plan,”
stressing the need to move beyond theoretical studies.
According to a 2024 report by the International Renewable Energy Agency (IRENA), geothermal power has the potential to supply 8.3% of global electricity needs by 2050 (IRENA Report).
