REGENLOOP is a DOE-funded project led by the
National Laboratory of the Rockies, with Alon Lidor
as principal investigator. It investigates the
conversion of captured CO₂ into CO, an intermediate
used to produce synthetic fuels and chemicals.
The process uses a ceria-based oxide in a two-step
chemical-looping cycle. Hydrogen first reduces the
oxide, producing water. CO₂ then reoxidizes the
material, producing CO in a separate reaction step.
These steps have different thermal demands:
hydrogen reduction requires heat, while the
CO₂ reaction releases it. The laboratory-scale
system incorporates an external fluidized bed of
inert particles to capture, store, and return
thermal energy between steps.
My summer work focused on developing and integrating
the experimental hardware and controls needed to
investigate this process.
