Precision Spectroscopy of CO2 Exchange in Hydrates for Clean Energy Production. Carbon dioxide capture and sequestration is a widely considered climate change mitigation strategy. Clathrate hydrates of natural gas, found in deep-water ocean sediments, represent a tremendous opportunity for simultaneous carbon dioxide sequestration and clean energy production.

Carbon dioxide capture and sequestration is a widely considered climate change mitigation strategy. Clathrate hydrates of natural gas, found in deep-water ocean sediments, represent a tremendous opportunity for simultaneous carbon dioxide sequestration and clean energy production. By injecting carbon dioxide into the hydrate reservoir, methane can be displaced and replaced by carbon dioxide. This project will use Raman spectroscopy and nuclear magnetic resonance imaged core-flood experiments to develop a fundamental understanding of the exchange mechanisms governing the replacement of the methane molecule in the hydrate cage with carbon dioxide. This knowledge will be critical for future development of these resources to safely extract methane from sub-sea hydrates.Read moreRead less
Near zero-emission hydrogen and carbon production from natural gas and bio-methane. Hydrogen is envisaged as a clean fuel for power generation particularly for the transportation sector. In the short- and mid-term future, hydrogen will be derived from fossil fuels. Based on the conventional processes, the route from fossil fuels to hydrogen invariably produces greenhouse gases. Geosequestration is a viable technique of storing carbon dioxide but has an uncertain long-term environmental ramifi ....Near zero-emission hydrogen and carbon production from natural gas and bio-methane. Hydrogen is envisaged as a clean fuel for power generation particularly for the transportation sector. In the short- and mid-term future, hydrogen will be derived from fossil fuels. Based on the conventional processes, the route from fossil fuels to hydrogen invariably produces greenhouse gases. Geosequestration is a viable technique of storing carbon dioxide but has an uncertain long-term environmental ramification. In contrast, our proposed technique avoids the production of greenhouse gases and, instead, engenders high value added graphitized carbon as a by-product. Given the relative stability and value of graphitized carbon, our catalytic cracking process provides another option to geosequestration.Read moreRead less
Use of Gas Expanded Liquids to Facilitate Process Intensification. The aim of this research is the utilisation of gas expanded liquids (GXLs) in technology platforms based on the principles of process intensification (PI). In order to facilitate the attainment of project objectives a comprehensive investigation of the fundamental properties of GXLs, and their interactions is proposed.

The aim of this research is the utilisation of gas expanded liquids (GXLs) in technology platforms based on the principles of process intensification (PI). In order to facilitate the attainment of project objectives a comprehensive investigation of the fundamental properties of GXLs, and their interactions is proposed. A significant component of the programme is expected to be to use the knowledge obtained to facilitate the development of scale-up protocol for PI based methodologies, with particular emphasis on the production of biomaterials. GXLs technology is frontier technology with regard to the biomaterials sector.Read moreRead less

Summary
Capturing Latent Methane Emissions from Natural Gas Production. Methane is 21 times more potent than carbon dioxide as a greenhouse gas. The natural gas industry produces significant methane emissions through collateral venting with nitrogen gas. Recovering waste methane will reduce greenhouse gas emissions and increase the revenue of natural gas processors. This project will develop the technology needed to capture the latent methane and significantly reduce its concentration in nitrogen gas ri ....Capturing Latent Methane Emissions from Natural Gas Production. Methane is 21 times more potent than carbon dioxide as a greenhouse gas. The natural gas industry produces significant methane emissions through collateral venting with nitrogen gas. Recovering waste methane will reduce greenhouse gas emissions and increase the revenue of natural gas processors. This project will develop the technology needed to capture the latent methane and significantly reduce its concentration in nitrogen gas rich vent streams. New adsorbents for separating these gases, such as molecular trapdoor zeolites, will be designed and tested over wide ranges of pressure and temperature. Dual reflux pressure swing adsorption cycles will be tested using the best materials to demonstrate how latent methane emissions can be reduced to part-per-million levels.Read moreRead less
Controlling hydrate slurry flow to enable deepwater oil and gas production. This project aims to investigate the plugging of hydrate slurries in pipelines to determine under what conditions they will flow satisfactorily without forming a blockage. Hydrate blockages are expensive and hazardous occurrences in oil and gas operations, so current prevention systems aim to avoid hydrate formation altogether through over-design. These over-designed hydrate prevention systems are extremely expensive to ....Controlling hydrate slurry flow to enable deepwater oil and gas production. This project aims to investigate the plugging of hydrate slurries in pipelines to determine under what conditions they will flow satisfactorily without forming a blockage. Hydrate blockages are expensive and hazardous occurrences in oil and gas operations, so current prevention systems aim to avoid hydrate formation altogether through over-design. These over-designed hydrate prevention systems are extremely expensive to build and costly to run during the operations phase. The project intends to examine the behaviour of hydrate slurry flow as a function of the oil's properties, amount of water and degree of turbulence. Outcomes are intended to be a sophisticated approach to avoiding hydrate blockages that is safe but more efficient and less costly.Read moreRead less

The results from this project will allow use of alternative sources for energy through a better understanding of the functioning, design, operability and control of SOFCs. Fuel Cells (FCs) with biomass ethanol feed will not only act as reliable power source but also reduce greenhouse gas emissions. A successful R&D effort to develop FCs will improve the national energy security by reducing the growing dependency on foreign energy sources, improve the environment by reducing carbon and other harmful emissions, and improve the economic growth by expanding the portfolio of highly efficient energy and useful spill over technologies.

Novel carbon dioxide tolerant ceramic membranes for oxygen separation to improve the viability of clean energy technology. Conventional cryogenic air separation is a major economic impediment to the deployment of these low emission technologies like Callide oxyfuel combustion. This project will lead to the discovery of a new class of oxygen selective membranes for air separation with significantly reduced cost to improve the viability of these clean energy technologies.
Syngas Production Using Catalytic Carbon Dioxide Dry Reforming. This project intends to pave the way for turning remote low-value Australian resources and greenhouse gases into valuable products. Most of Australian natural gas reserves are located in the remote north-west shelf, and many are small scale and thus cannot be economically harnessed using conventional methods such as pipeline transportation or gas liquefaction. In this project, a dry reforming reactor with novel catalysts will be des ....Syngas Production Using Catalytic Carbon Dioxide Dry Reforming. This project intends to pave the way for turning remote low-value Australian resources and greenhouse gases into valuable products. Most of Australian natural gas reserves are located in the remote north-west shelf, and many are small scale and thus cannot be economically harnessed using conventional methods such as pipeline transportation or gas liquefaction. In this project, a dry reforming reactor with novel catalysts will be designed for converting natural gas and carbon dioxide to syngas, which is an intermediate step of gas-to-liquid plant. By innovatively integrating advanced catalysis and heating technologies, reactor weight and operational costs will be minimised.Read moreRead less
