There's a global race to reduce the amount of harmful gases in our atmosphere to slow down the pace of climate change, and one way to do that is through carbon capture and sequestration — sucking carbon out of the air and burying it. At this point, however, we're capturing only a fraction of the carbon needed to make any kind of dent in climate change.
Researchers from The University of Texas at Austin, in partnership with ExxonMobil, have made a new discovery that may go a long way in changing that. They have found a way to supercharge the formation of carbon dioxide-based crystal structures that could someday store billions of tons of carbon under the ocean floor for centuries, if not forever.
"I consider carbon capture as insurance for the planet,” said Vaibhav Bahadur (VB), an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering and the lead author of a new paper on the research in ACS Sustainable Chemistry & Engineering. “It's not enough anymore to be carbon neutral, we need to be carbon negative to undo damage that has been done to the environment over the past several decades.”
These structures, known as hydrates, form when carbon dioxide is mixed with water at high pressure and low temperature. The water molecules re-orient themselves and act as cages that trap CO2 molecules.
