New research at The University of Texas at Austin shows that injecting air and carbon dioxide into methane ice deposits buried beneath the Gulf of Mexico could unlock vast natural gas energy resources while helping fight climate change by trapping the carbon dioxide underground.
The study, published June 27 in the journal Water Resources Research, used computer models to simulate what happens when mixtures of carbon dioxide and air are injected into deposits of methane hydrate, an ice-like, water-rich chemical compound that forms naturally in high-pressure, low-temperature environments, such as deep in the Gulf of Mexico and under Arctic permafrost.
Lead author Kris Darnell, a recent doctoral graduate from the UT Jackson School of Geosciences, said the research is the next step in solving two significant global challenges: energy security and carbon storage.
“Our study shows that you can store carbon dioxide in hydrates and produce energy at the same time,” said Darnell, whose research was funded by the University of Texas Institute for Geophysics (UTIG).
