Journal article
In: Renewable and Sustainable Energy Reviews,
Elsevier,
March 2025
Abstract: Global geothermal energy utilisation for power generation and direct-use applications have increased over the past 25 years, with Asia having the fastest growth in direct-use applications, which suggests a high demand for geothermal resources in Asia. This review seeks to fill a critical gap in the existing literature on geothermal development in South, Southeast and East Asia. …

Abstract: This study presents a comparison of pathways to emission reduction in Singapore including its neighbouring countries. Given Singapore’s limited renewable resources, electricity imports are one possible pathway to reduce the country’s carbon footprint. This study quantitatively shows that restricting greenhouse gas (GHG) emissions in Singapore alone leads to a higher dependence …

Abstract: A deep exploratory slimhole reaching a depth of approximately 1.1 km was successfully completed in the northern part of Singapore. The rock cores extracted from the exploration slimhole provide a unique opportunity to understand rock conditions past few hundred metres deep and generate datasets such as overall rock conditions and concentrations of various elements. …

Abstract: Singapore is exploring potential geothermal reservoirs to reduce its reliance on natural gas and transition towards sustainable energy sources. With only 4 % of registered power generation capacity coming from renewables, the city-state aims to achieve net-zero emissions by 2050. The study focuses on harnessing low- to medium-temperature geothermal resources for electricity …

Abstract: Optimizing geothermal heat extraction requires a deep understanding of the thermal properties of host rock. This study identifies the governing factors to enhance heat extraction rate and efficiency under various geological and operational conditions, using both water flow experiments and 3D numerical models. Our results indicate that the surrounding temperature and flow rate …

Abstract: Singapore has at least two known hot springs with surface water temperatures of 50–90°C. Together with its estimated high heat flow, Singapore is thought to have a geothermal potential. To assess the potential, we focus our study on the northern part of Singapore, where elevated shallow subsurface temperatures have been identified. Two deep exploratory slimhole sites are …

In: Sustainability,
MDPI,
June 2024
Abstract: About 20 % of the world’s CO2 emissions originate from transport. Many countries are committed to decarbonizing their transport sector. Singapore pledged to electrify a whole host of its land transportation fleet which includes private cars, public buses, ride-hail vehicles, and motorcycles. This paper proposes a simple empirical framework to estimate the …

Conference paper
In: Proceedings of the 2023 IEEE PES Conference on Innovative Smart Grid Technologies (ISGT) Asia,
IEEE,
November 2023
Abstract: This study investigates green hydrogen production using a closed-loop geothermal system integrated with an organic Rankine cycle (ORC). Geothermal energy powers the ORC turbine, generating electricity for hydrogen production through water electrolysis. The study quantifies the global warming potential (GWP) of the production of green hydrogen. Notably, the GWP is low at …
