Abstract:
Large amounts of methane exist in the earth in the form of natural gas hydrates (NGH), an ice-like substance with hydrocarbon molecules trapped within by water cages. The amount of carbon stored as NGH is more than twice the carbon content present in all fossil fuels combined. It has been demonstrated that conventional gas production techniques can be employed to produce energy from natural gas hydrates. Thermal stimulation, depressurization or a combination of both these methods are the approaches to recover natural gas. One innovative and promising solution to secure the future energy needs and mitigate carbon dioxide emissions simultaneously is to replace methane trapped in the gas hydrate deposits with carbon dioxide. There are specific challenges like sand and water management during energy production that needs to be overcome/mitigated to sustain methane production from NGH. Thus, there is an overwhelming need to pursue research and development at laboratories in order to exploit this huge resource in the future. In this work, the state-of-the-art experimental work in methane production from natural gas hydrates carried out at the National University of Singapore will be summarized and future directions and challenges will be outlined.
Keywords: gas hydrates; energy recovery; methane hydrates; thermal stimulation; depressurization; carbon dioxide fixation.
Biography of presenter:
Praveen LINGA is faculty in the Department of Chemical and Biomolecular Engineering at the National University of Singapore (NUS). He also serves as an associate editor in the journal of natural gas science and engineering (Elsevier UK). He works in the frontier research areas of energy and environment. His research interests are in the areas of clathrate (gas) hydrates, energy storage, CO2 capture storage & utilization, desalination and energy recovery. Up to date, he has published more than 50 research articles and delivered about 20 keynote/invited talks. His research has received numerous awards that include four most cited paper awards in reputed journals.
