Summary
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. By injecting carbon dioxide into the hydrate reservoir, methane can be displaced and replaced by carbon dioxide.

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

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
