Tailpipe CO2 Onboard Capture System
Valero continues to support Southwest Research Institute (SwRI) in the development of a solid CO2 separation
membrane to remove CO2 from the exhaust gas of internal combustion engine vehicles, with the objective of
providing an affordable solution to lowering GHG emissions. To date, SwRI has improved upon the initial concept
and demonstrated performance enhancements through design and optimization efforts.
Plans are in place for prototype scaling and testing,
and we have 昀椀led patent applications for several novel
technologies. If successful on a commercial scale, cars
built with this technology could compete with EVs as
a low-cost solution for reducing tailpipe emissions.
In addition, even greater bene昀椀ts to life cycle GHG
emissions reductions are possible if low-carbon fuels are
used in combination with the onboard capture system.
Carbon Capture
and Storage or
CCS
CCS is a proven
technology that has
been in commercial
use for decades in
the oil and gas and
fertilizer industries. It
involves three steps:
1. Capture:
Separation of CO2
from other gases
produced at industrial
process facilities.
2. Transport:
Separated CO2
dehydrated and
compressed prior to
being transported by
pipeline, rail, trucks or
ships for storage.
3. Storage:
CO2 destined for
permanent storage
and injected into deep
rock formations.

Industrial Carbon Capture — Valero 昀椀rst used carbon capture technology in 2013
at its re昀椀nery in Port Arthur, Texas. Approximately 1 million metric tons of CO2 per
year is captured from two third-party hydrogen plants that produce hydrogen
from natural gas.
Large-Scale CCS —
Valero has agreed
to participate as a
shipper on Summit
Carbon Solutions'
proposed pipeline
project by connecting
eight of Valero's
ethanol plants and
enabling the capture
and storage of
approximately
3.1 million metric tons
CO2 annually, which
could potentially
reduce Valero's
ethanol's CI by
approximately 40%.

Stand-Alone CCS — We are continuing to evaluate and develop stand-alone
carbon sequestration projects at several of our Eastern ethanol plants, potentially
capturing more than 1 million metric tons of CO2 a year. Certain of our ethanol
plants are located near geology believed to be suitable for successful CCS
projects, making them potentially attractive for development.
