US$2 million DOE grant awarded to engineer to study CO2 capture

The DOE’s Office of Fossil Energy, National Energy Technology Laboratory (NETL) has awarded Joan Brennecke, the Keating-Crawford Professor of Chemical and Biomolecular Engineering, a US$2 million US Department of Energy (DOE) grant for research into how ionic liquids, or salt in a liquid state, can improve the efficiency and economics of the carbon dioxide (CO2) capture process.

Ionic liquids require less energy than today’s approaches to capturing CO2.

Brennecke will study the encapsulation of solid compounds that turn into an ionic liquid when they react with CO2 and turn back into a solid when the CO2 is released.

Brennecke believes ionic liquids are a potentially pivotal component of an integrated system that can safely and economically sequester combustion-generated CO2, thereby mitigating its impact on climate change.

The liquids have the potential to efficiently capture CO2 from the flue gas of coal-fired plants, as demonstrated in 2004 by a research team led by Brennecke and Edward J. Maginn, the Dorini Family Professor of Energy Studies and chair of the Department of Chemical and Biomolecular Engineering, as part of a project sponsored by the DOE’s National Energy Technology Laboratory.
