Abstract - Carbon capture and storage (CCS) is essential if global
warming mitigation scenarios are to be met. However, today's maturing
thermochemical capture technologies have exceedingly high energy
requirements and rigid form factors that restrict their versatility and
limit scale. Using renewable electricity, rather than heat, as the
energy input to drive CO2 separations provides a compelling alternative
to surpass these limitations. Although electrochemical technologies have
been extensively developed for energy storage and CO2 utilization
processes, the potential for more expansive intersection of
electrochemistry with CCS is only recently receiving growing attention,
with multiple scientific proofs-of-concept and a burgeoning pipeline
with numerous concepts at various stages of technology readiness. In
this presentation, I describe the emerging science and research progress
underlying electrochemical CCS processes and assess their current
maturity and trajectory. I also highlight emerging ideas that are ripe
for continued research and development, which will allow the impact of
electrochemical CCS to be properly assessed in coming years.
Biography - Dr. Rahimi is an Assistant
Professor of Environmental Engineering at the Cullen College of
Engineering at the University of Houston (UH). He also holds an affiliate
appointment with the
Materials Science and Engineering Program. Before joining UH, Dr. Rahimi was a
postdoctoral
associate at the Department of Chemical Engineering at Massachusetts Institute
of Technology
(MIT) (2018–2021) working with Prof. Alan Hatton. Dr. Rahimi obtained his Ph.D.
in chemical
engineering from Pennsylvania State University in 2017 under the supervision of
Prof. Bruce
Logan. His research group at UH develops electrochemical processes for climate
change
mitigation, including a wide range of technologies for carbon capture from air
and point sources.
