Stimuli-Responsive Metal Organic Frameworks
Technology Description:
A team led by three professors at Texas A&M University is developing a subset of metal organic frameworks that respond to stimuli such as small changes in temperature to trap CO2 and then release it for storage. These frameworks are a promising class of materials for carbon capture applications because their structure and chemistry can be controlled with great precision. Because the changes in temperature required to trap and release CO2 in Texas A&M's frameworks are much smaller than in other carbon capture approaches, the amount of energy or stimulus that has to be diverted from coal-fired power plants to accomplish this is greatly reduced. The team is working to alter the materials so they bind only with CO2, and are stable enough to withstand the high temperatures found in the chimneys of coal-fired power plants.
Potential Impact:
If successful, the materials developed at Texas A&M would reduce the cost of carbon capture, enabling accelerated retrofitting of existing coal-fired power plants while satisfying consumer demand for electricity.
Security:
Enabling continued use of domestic coal for electricity generation will preserve the stability of the electric grid.
Environment:
Carbon capture technology could prevent more than 800 million tons of CO2 from being emitted into the atmosphere each year.
Economy:
Enabling cost-effective carbon capture systems could accelerate their adoption at existing power plants.
