The first technical session, "Energy Sustainability in a Carbon Constrained World," kicks off with a PowerPoint-fueled presentation from Robert R. Romanosky
, advanced research technology manager at the Department of Energy's
National Energy Technology Laboratory.
starts by noting that U.S. carbon dioxide emissions total 6.3 billion tons a year.
"We've been taking a look at how do we mitigate the problem," he
"We've been looking at two key areas.
One is improving efficiency.
The other major approach is carbon capture and sequestration.
"No matter how we choose to do it, the factor at the end is we have to capture the carbon," he
reviews a variety of new technologies that are currently being tested for their ability to capture pure carbon dioxide as part of the energy-production process.
That CO2 can then be sequestered in geological formations deep in the earth.
