Journal article
In: International Journal of Hydrogen Energy,
Elsevier,
2025
(early access)
Abstract: Liquid hydrogen (LH2) is a promising solution to transport green hydrogen to countries lacking domestic energy resources. One challenge in simulating the liquefaction process is the exothermic ortho-para conversion (OPC). Orthohydrogen is converted to parahydrogen during the process to prevent the liquid hydrogen from evaporating due to the exothermic conversion in …

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. …

Conference paper
In: Proceedings, 50th Workshop on Geothermal Reservoir Engineering,
Stanford University,
February 2025
Abstract: Singapore is a small, densely populated urbanized city-state that relies on energy imports for self-sustainability and security due to the lack of natural resources. Aside from renewable energy sources, including solar energy, geothermal power could also be a viable domestic source of energy. Hot springs and anomalous regional heat flow indicate that the country have geothermal …

Conference paper
In: Proceedings of the IEEE Region 10 Conference 2024 (TENCON 2024),
IEEE,
December 2024
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 …

Chapter in multi-author book
In: Lecture Notes in Civil Engineering,
Springer,
July 2024
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. …

Springer,
July 2024
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 …

In: Lecture Notes in Civil Engineering,
Springer,
July 2024
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 …

Chapter in multi-author book
In: Lecture Notes in Civil Engineering,
Springer,
July 2024
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 …

Journal article
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 …
