“Electrochemical capture of
CO2”
Wednesday, June 27, 2007
12 PM Seminar in Hamerschlag B131
Refreshments will be served.
CO2 capture and sequestration will be required in
the future to limit the impact of CO2 emissions on
the global environment. The massive scale of
the capture requirements makes the energetic efficiency
of the system and the recycling of reagents two of
the most critical parameters in evaluating competing
systems. The equilibrium efficiencies of electrochemical
processes are very high. Any operating capture process
would not operate under equilibrium conditions, however,
and consequently would have a lower overall efficiency
than expected from simple thermodynamics. We will discuss
an electrochemical CO2 capture system we have been
investigating as well as some alternative electrochemical
schemes and the technology developments that will be
necessary to make them competitive with existing technologies. |
